The “write amplification effect” refers to the fact that when an SSD performs a write operation, the actual amount of data written may be greater than the amount of data requested by the user. This accelerates the wear and tear of the flash memory cells. To reduce the write amplification effect, it is helpful to use the TRIM command and maintain enough free space.

Increasing memory can improve performance, especially for systems running large applications, virtual machines, or multitasking operations. However, when the amount of memory is enough for daily demand, the boost effect of adding memory becomes smaller.

SSDs are temperature sensitive, and sustained high temperatures may affect their longevity and performance. It is recommended to use it in a normal working environment and monitor the temperature regularly. All of Oreton’s SSDs (2.5″ SATA, M.2 SATA and M.2 NVMe) have an operating temperature in the range of 0~70°C, and if used in extreme conditions, it may be more appropriate to choose a high-temperature, industrial-grade SSD.

While it’s possible to mix different brands of memory, ideally, you should use the same brand, frequency, and capacity to ensure stability and compatibility. When mixing memory at different frequencies, the system defaults to running at a lower frequency, which can impact performance.

SSDs can be used in RAID configurations, but be aware that different RAID levels will have different impacts on performance and data protection. RAID 0 increases read and write speeds but does not have data redundancy, while RAID1 provides redundancy at the expense of half the storage space. In addition, some RAID controllers may not be able to fully exploit the performance of the SSD.

Single-channel memory can only use one memory channel at a time to transfer data, while dual-channel memory can use two channels at the same time to transfer data, providing higher bandwidth and performance. For a dual-channel configuration, it is recommended to install two memory modules of the same capacity and frequency.

Enable TRIM: Ensure that the operating system supports and enables the TRIM command to help the SSD manage data more efficiently.

Avoid completely filling the SSD: keep at least 10-20% free space for garbage collection and performance optimization.

Upgrade Firmware: Periodically check the manufacturer’s website and update the SSD firmware, which may improve performance or fix vulnerabilities.

Disable system defragmentation: Do not defragment your SSD as this will have an impact on its lifespan.

Single-channel memory can only use one memory channel to transfer data at a time, while dual-channel memory can use both channels to transfer data at the same time, providing higher bandwidth and performance. For dual-channel configuration, it is recommended to install two memory sticks of the same capacity and frequency.

Yes. Upgrading older computers to SSDs usually results in significant speed and responsiveness improvements. Even older SATA interfaces will see large improvements. However, ensuring that the motherboard interface is compatible with the SSD is necessary.

Yes, heat dissipation of memory sticks is an important issue, especially in high performance or overclocking situations. Memory sticks running under high loads generate heat, and excessive temperatures can affect stability and performance. For this reason, heatsinks or fans can be used to help reduce memory temperatures and ensure reliable system operation.

1. Turn off the computer and unplug it.
2. Open the case and locate the memory slot on the motherboard.
3. Align the notch of the memory stick with the slot and gently insert it until you hear a ‘click’ sound, indicating that the memory stick is locked in place.
4. Close the case, reconnect the power supply, and start the computer.

When choosing DDR memory, both capacity and frequency are important, but the priority depends on the specific usage scenario. For most users, especially those who are multitasking or working with large applications, increasing the memory capacity will improve the overall performance more than increasing the frequency. However, in certain situations, such as certain gaming or specialized applications, an increase in frequency may result in better performance.

Data recovery is possible, but it is more difficult than with HDDs because SSDs use the TRIM command to clean up unused blocks, which may result in permanent loss of some data.

The nominal frequency of a DDR memory stick is the maximum data transfer speed it can achieve under normal operating conditions, usually expressed in MT/s (million transfers per second). For example, DDR4-2400 means that the maximum transfer speed of this memory is 2400 MT/S.

Even though SSDs are more durable, prolonged periods of non-use or extreme conditions can still lead to data corruption. Therefore backing up your data on a regular basis is the recommended practice.

There may be a compatibility issue between your SSD and the platform. Please follow the steps below to troubleshoot (listed in order of likelihood):

1. Check if your PCIe SSD is running the latest firmware version. If not, update it to latest version using SSD Scope.
2. Please also make sure your platform BIOS is up-to-date.
3. For Windows OS, we suggest any version later than 1709. (Check your OS version in Settings -> System -> About)
4. Download and install the latest driver for all devices (e.g. chipset, power management, display card, etc.) used on the platform from their official websites.

If you’re using an IDE SSD, there’s no need to install a driver. But if you are using a SATA SSD, it will depend on your system requirements. Please contact your computer system or motherboard manufacturers if a driver is required when you are installing an OS.

Currently, there are three main types of memory packages, such as TSOP, BGA, and CSP, and the packaging method also affects the performance of memory sticks.

TSOP package: a typical feature of TSOP( Thin Small Outline Package) is to make a lot of pins around the encapsulated chip.TSOP package is easy to operate, relatively high reliability, is the current mainstream packaging method.

BGA package: BGA is called ‘Ball Grid Array Package’, its biggest feature is that the number of pins of the chip has increased, and the assembly yield has been improved. The use of BGA package can make memory capacity increase by two to three times under the condition of the same volume, compared with TSOP, it has a smaller volume, better heat dissipation performance and electrical performance.

CSP package: CSP (Chip Scale Package) as a new generation of packaging, and its performance has been greatly improved, CSP package is not only smaller, but also thinner, and can improve the reliability of the memory chip for a long time, the chip speed has been greatly improved. Currently, this package is mainly used for high-frequency DDR memory.

It’s true that flash memory comes in different qualities, corresponding to different costs, just like CPUs. usb flash drives generally use lower grade flash memory, and if you use a usb flash drive as a hard drive, I think you’ll immediately feel the difference in SSD performance. Also in terms of reliability, the difference between good and bad flash memory is obvious. High-quality flash memory chips have a much lower chance of error throughout their life cycle.

First of all, we need to understand our usual use of the PC, is the read more or write more? Open the PC into Windows: a lot of reading + a small amount of writing; open large software: a lot of reading + a very small amount of writing. It seems that for the average user, it is clear that the application of reading more than writing applications, but when you download an MP3 and stored in the SSD above, it is a write action, the production of an Office document, but also a write action, I do not know if you find that the action of writing is often a number of small files, compared to the mechanical hard drive, SSD, small files read and write performance is not very strong, which is why many SSD test software will have 4K file storage test project, early first-generation SSD in reading and writing small files sometimes lag a little, but today’s mainstream SSDs have been through their respective different ways (increase cache, etc.) to make up for this defect in SSD, users can rest assured.

FBGA (Flip Chip Ball Grid Array) is a form of packaging for integrated circuits whose main advantages include:

Reduced size: The main purpose of the FBGA package form factor is to reduce the size of the chip, allowing electronic devices to be more compact and space-saving. This is especially important for electronic products that require a high degree of integration, as it allows designers to integrate more functionality in a limited space.

Slight speed increase: In addition to reducing size, FBGA packaging can also slightly increase the speed at which the chip operates, which can have a positive impact on improving the overall performance of an electronic device. While this speed increase may not be significant, it can be critical for applications seeking high performance.

Different methods of calculating capacity: For the convenience of calculation, storage device manufacturers use the decimal calculation method, which is based on 1000 (103) as the conversion unit, i.e. 1GB = 1000MB. Whereas computers use binary, the system is using 1024 (210) as the unit of conversion, i.e. 1GB = 1024MB. The capacity of the USB flash drive identified by the computer will be less than the nominal capacity of the USB flash drive manufacturer, and the actual capacity will be about 90% of the labelled capacity. Therefore, the actual capacity of all USB flash drives are smaller than the marked capacity, generally speaking, 8G is about 7.45G, 16G is about 14.9G, and so on.

Problems with the chip itself: Due to problems with the flash chip itself during manufacturing, the flash media is allowed to have bad blocks, which are not counted as effective capacity because they cannot be used.

USB flash drive itself file system occupancy: USB flash drive and hard disk, flash drive is also generally used FAT file system, and the FAT file system including MBR master boot partition, FAT file allocation table and ROOT directory area, etc., these areas also want to take up space, generally need to take up a few hundred kilobytes.

SSDs do not get bad sectors since they have no physical sectors. Therefore, traditional hard drive detection tools are not suitable for SSD examination.

Pin Count and arrangement: Different generations of DDR chips differ in pin count and arrangement. For example, DDR1 has a pin count of 92 pins on one side and 184 pins on both sides, while DDR2 and DDR3 both have 120 pins on one side and 240 pins on both sides, and they also have different pin arrangements.

Memory chips shape: Both DDR2 and DDR3 memory chips are square, while DDR2 uses 1.8V and DDR3 uses 1.5V, which indicates that with the development of technology, the operating voltage of memory is gradually reduced, while the power consumption is also gradually reduced.

PCB layout and gold finger design: There are significant differences in the way DDR4 is laid out on the PCB compared to DDR3, as well as adjustments to the location of the gold finger anti-dumbing latch, indicating that the design of the memory is constantly being optimised as technology advances to accommodate higher data transfer rates and lower power consumption requirements. 

Size and thermal design: DDR2 memory modules are typically slightly larger than DDR3 memory modules, and DDR3 memory modules are designed to be more compact and efficient, and may have more advanced thermal designs, such as thinner heatsinks or more efficient heat dissipation materials, to cope with higher transfer rates and power consumption.

USB 3.2 Gen 1 refers to another name for USB 3.0, which is an upgraded version of USB 3.0 that offers higher transfer speeds and higher bandwidth.USB 3.2 Gen 1 offers transfer speeds of up to 5Gbps, which is 10 times faster than USB 2.0; it is also slower than USB 3.2 Gen 2, which has a transfer speed is up to 10Gbps.

USB 3.2 Gen 1 interfaces are backward compatible with USB 2.0 and USB 1.1, which means you can connect older USB devices on the newer USB 3.2 Gen 1 interfaces.

It is important to note that USB 3.2 Gen 1 is also known as USB 3.1 Gen 1. This is because prior to 2017, USB 3.2 Gen 1 was known as USB 3.1 Gen 1. It was later renamed to USB 3.2 Gen 1 by the USB Developers Forum based on the new naming convention.

CAS Latencys refers to the delay time required for memory to access data, simply put, it is the reaction speed of the memory after receiving the instruction from the CPU, which is one of the important parameters of the memory.CAS Latencys is related to the performance of the memory in terms of reading and writing, and the timing of the memory is theoretically the lower, the better, but the prerequisite is to ensure that it can be operated in a stable manner.

Memory stick slot problem: To determine if this problem exists, you need to check that the memory stick is properly inserted into the memory slot. Make sure that the slots are not loose or dirty. Try re-inserting and re-plugging the memory sticks to make sure they are firmly inserted into the correct slots and orientated correctly. Sometimes you may need to gently press down on the memory sticks until the clips on both sides automatically bounce back to hold them in place. After this, restart the computer to see if the motherboard recognises the memory correctly.

Compatibility issues: There may be compatibility issues between different motherboards and memory. Check your motherboard’s user manual or visit the manufacturer’s website to confirm that the type of memory you are using meets your motherboard’s requirements. If there is a compatibility issue, it is recommended to replace the memory stick with a compatible one.

Damaged memory sticks: There may be a problem with the memory sticks themselves that prevents the motherboard from recognising them correctly. Try inserting the memory sticks one by one and test them, inserting them individually into each memory slot and restarting the computer to see if they are recognised correctly. If only one of the memory sticks is not recognised, it is likely that it is damaged and you will need to replace it with a new one.

BIOS settings: In some cases, the motherboard’s BIOS settings may affect the memory recognition. Enter the BIOS interface (usually by pressing the Del, F2 or Esc key) and check the ‘Memory Settings’ or related options to make sure the memory is recognised and configured correctly. Try to reset the BIOS settings to default, save and exit the BIOS interface, then reboot the computer to see if the motherboard can recognise the memory correctly.

Update motherboard firmware: Some older motherboard firmware may have memory compatibility issues. Please find and download the latest motherboard firmware from the manufacturer’s website and follow the instructions to update it. Updating the motherboard firmware may require a certain level of technical skill, so please make sure you understand the procedure and safety risks before proceeding.

High SMART temperature readings of SSDs can be caused by reading and storing data for long periods of time, or because of the environmental conditions around the SSD, the amount of space available for heat dissipation, and other factors. In order to solve this problem, there are some measures that can be taken to reduce the temperature of the SSD, such as adding auxiliary cooling devices, using software to intelligently cool down the temperature, streamlining unnecessary startup items, and checking for and dealing with viruses.

Use Eraser: Eraser can effectively remove the oxidised layer on the gold fingers. Simply place the memory stick on a flat surface of the desk and rub the gold finger area repeatedly with the eraser. This method can remove some of the stains and oxides, but may not be effective for the oxide layer on the metal surface. The cleaning process should not be too strong to prevent damage to the gold finger.

Technical limitations: There may be technical limitations in the design and manufacture of DDR (Double Data Rate Synchronous Dynamic Random Memory) that prevent it from reaching the specified frequency. For example, the internal clock speed and data transfer rate of a DDR module may be affected by factors such as chip design and manufacturing process, thus limiting its performance.

Hardware design issues: Defects or deficiencies in hardware design may also cause DDR modules to fail to operate at the specified frequency. For example, if the master controller chip lacks necessary features such as read/write balancing, this may lead to problems with data transfer timing, which may affect the performance of the module.

Software configuration issues: In some cases, the performance of DDR modules is also affected by software configuration. For example, memory modules may run at JEDEC frequencies by default on the motherboard, such as 2133, 2666, etc. To reach the nominal frequency of the memory you may need to enable XMP ( Extreme Memory Profile) or manual overclocking settings.

Compatibility issues: If a DDR module has compatibility issues with the motherboard or other system components, it may also fail to run at the specified frequency. For example, DDR4 memory modules are typically not compatible with DDR3 memory slots, and even if some motherboards support slots for both DDR3 and DDR4 memory, the memory module will run at lower speeds and timings.

Power management settings: the power management settings of Windows 10 system may affect the performance of USB external devices. For example, if High Performance mode is turned on in Power Management, it may cause USB devices to run slower. It is recommended to check and adjust the power management settings to ensure that they are in balanced or energy-saving mode, or try restoring the default values of the plan settings.

Driver Issues: Outdated or maladaptive drivers can also be the cause of slower operation of USB external devices. Make sure all relevant drivers such as Intel Management Engine Interface driver, Intel Rapid Storage Technology driver. Intel INF installation driver, etc., are up-to-date, which can help improve the operating efficiency of the USB device.

System Configuration: The overall configuration of the system, including CPU, RAM, and the type and performance of the hard drive, will affect the performance of the USB external device. For example, if the system itself has a low performing hard drive, then the overall speed of data transfer through the USB interface will be affected.

In addition, the type and version of the USB interface also affects the data transfer speed. For example, the theoretical maximum transfer speed of USB 3.0 is 5Gbps, but in practice, the actual transfer speed may vary due to factors such as device compatibility, interface usage, and the degree of optimisation of the operating system and file system. The actual transfer speed may vary.

Using the Memory Inspection Tool

1、Windows Memory Diagnostic Tool: In Windows operating system, there is a memory diagnostic tool, which can help us detect whether there is a problem with the memory. To do this, type “Memory Diagnostics” in the search bar and select “Windows Memory Diagnostics”.

2、Third-party Memory Diagnostic Tools: In addition to the tools that come with Windows, there are many third-party memory checking tools available. These tools usually have more powerful features and more detailed reports.

1、Memory sticks not inserted tightly or damaged: If the memory sticks are not fully inserted or are physically damaged, the computer will not correctly recognise the full memory capacity. Ensure that each memory stick is properly inserted and secured, and if necessary, try reinstalling the sticks to improve contact.

2、Incorrect BIOS Settings: Memory settings in the BIOS are critical for correctly recognising memory capacity. If the settings are incorrect, the computer may not recognise all of the memory. Check the memory settings in the BIOS to make sure they match the actual memory installed.

3、Memory incompatibility with the motherboard: Some memory sticks may be incompatible with a particular model of motherboard, resulting in the computer not recognising all of the memory. Check the compatibility list provided by the motherboard manufacturer to ensure that the selected memory is compatible with the motherboard. 

1、Hardware connection problems: The connection between the SSD and the computer’s motherboard may be poor or damaged, including poor or damaged contact with the SATA cable or power cable. Ensuring that all connections are secure and not frayed or damaged is the first step in resolving the issue.

2、Improper BIOS settings: In some cases, it is necessary to manually enable the SATA controller in the BIOS to recognise the SSD. Checking if the SATA controller is enabled is a necessary step.

3、Incompatible or missing drivers: The operating system may be missing the proper SSD driver, or the existing driver may not be compatible with the new SSD model. Updating or installing the correct driver can solve the problem.

4、Partitioning and formatting issues: If the SSD is not properly partitioned or formatted, the operating system may not recognise it. Creating a new partition and formatting it using a disc management tool may help to solve the problem.

5、Firmware issues: Firmware issues with the SSD may also cause recognition failure. A firmware upgrade may be a solution.

6、System compatibility issues: Ensure that the operating system supports the SSD being used. In some cases, it may be necessary to update the operating system or install drivers compatible with the SSD.

7、Hardware conflicts: Sometimes other hardware devices may conflict with the SSD. Try unplugging the other SATA device to determine if such an issue exists.

8、Failure of the drive itself: Ensure that the power supply is providing enough power and is able to power the SSD consistently.

Generally speaking, SSDs and HDDs consume similar amounts of power when they are working under the same high loads, or when they are also in a dormant state. However, SSDs still have some advantages in terms of power performance, such as the fact that SSDs do not have an internal rotating motor, and therefore consume significantly less power in the idle state. Second, because there is no ramp-up or ramp-down startup time, SSDs enter or wake from hibernation in less time and more frequently. Finally, SSDs are able to do the same work in less time and therefore enter hibernation earlier. All of these advantages make SSDs more energy efficient than traditional hard disks in the real world.

First of all, memory and hard disc are different in function. Hard discs are mainly used for long-term data storage to retain as much user data as possible, while the main function of RAM is for temporary data storage and data exchange between the CPU and the operating system, so that the user can use the programme as smoothly and quickly as possible.

Secondly, they are also different in performance. The performance of the hard disc mainly depends on its data transfer speed and storage medium, only need hard disc data reading speed is fast enough; while the performance of the memory is dependent on its processing data speed, that is, what we call the frequency, the faster the frequency of memory, the faster the speed of data exchange, therefore affecting its performance.

Finally, the size of their capacity also varies greatly. Hard drive usually has a larger storage capacity, common SSD and HDD hard drive capacity of hundreds of GB to several TB; while the capacity of the memory stick is relatively small, common only 4GB, 8GB, 16GB, etc., although with the development of technology, also gave birth to a single 48GB memory stick, but compared with the hard drive is still a huge gap.

The performance of any SSD is determined by a combination of raw flash bandwidth, the efficiency of the loss balancing algorithm (firmware), and the interface (SATA, PCI-E, etc.). With SATA interface speeds stuck there, there’s no point in having great flash performance.

Buy two memory sticks with exactly the same parameters, that is, if you want the memory capacity is 8G, then buy two 4G, if you want 16G, then buy two 8G, now many manufacturers are directly producing sets of strips, the budget allows direct purchase of sets of strips can be. Then insert them at intervals or in the same colour on the motherboard.

The answer to this question is a bit more complicated. The way SSDs store data is significantly different from traditional hard discs, for example, to prevent frequent reads of a storage unit that can lead to rapid aging, SSDs tend to use a ‘wear levelling’ mechanism that averages out the number of reads and writes to each block. Current operating systems are not prepared for this.

The main principle of the disk defragmenter is to put the data that needs to be read frequently where it can be accessed at high speed, and the data that is rarely accessed is piled up in the corners. The principle of SSD is that it can find any piece of data very quickly. Current disk defragmentation tools just can’t do anything to optimise the file system of an SSD. Therefore, my recommendation is that SSD users should disable automatic disk defragmentation and not do it manually either.

Timing refers to the latency of the memory, and is generally shown using four sets of parameters with dashes, e.g., 16-18-18-36, CL-TRCD-TRP-TRAS, respectively;

We generally focus only on the first parameter, the CL value, which can be roughly interpreted as the reflection time; in most cases, the lower the CL value, the better, given the same memory frequency.

Like two sides of anything else, SSDs and HDDs have their advantages and disadvantages. By far the biggest disadvantage of SSDs is cost and capacity, while the biggest advantage is performance. Additionally, SSDs require less power to perform the same operation, which means that laptops can have longer battery life and data centers can save significantly on their electricity bills. Because they are more resistant to shock and vibration, SSDs are also better suited to mobile devices than HDDs. SSDs can even be cheaper than traditional hard drives if capacity is not required.

    (1) Determine the type of memory stick based on the CPU and motherboard;

　 (2) Determine the capacity of the memory;

　 (3) Determine the quantity: according to the number of slots and the number of channels supported by the motherboard;

　 (4) Determine the frequency of the memory stick according to the frequency range supported by the CPU and motherboard: memory sticks with low timings perform well, and memory sticks with higher frequencies perform better at the same timings;

　 (5) Determine the brand: Pay attention to the memory particles and timings.

This is a complex issue. Over the life cycle of an SSD, many factors can affect its performance. Not the least of these is the issue of data fragmentation. Unfortunately, there is no way to externally measure the impact of data fragmentation on an SSD. As stated above, test programs may be able to detect a performance difference between an SSD’s internal storage stripe or not, but it doesn’t significantly affect the user experience. Optimization of the SSD file system will further address this issue in the future.

Computer to upgrade memory, the first step is to determine what kind of memory stick is installed in the computer.

The first method is to read the memory stick information in the boot information, some computers do not show the basic information on boot or need to press ESC or Tab key to see it, or read it in the BIOS.

The second method is to use system tools or commands, or third-party software such as CPU-Z, Thaiphoon, LU Master, etc. to read, the disadvantage is that it needs to be installed.

The main reason is that “reasonable capacity” flash memory does not take up much space in terms of physical specifications, and it is more appropriate to make it 2.5″ or 1.8″. The term “reasonable capacity” refers to the ability to provide enough storage space for real-world applications at a reasonable price. If the flash memory to fill a 3.5-inch hard disk space, the price must be quite amazing.

Many people may have a misconception about this, thinking that SSDs don’t come in 3.5″ models because it’s only for the laptop market. In fact, SSDs have never excluded desktop PCs, and there is no difficulty in installing a 2.5-inch SSD in a 3.5-inch drive bay in a desktop PC. Moreover, there is no difference between the SATA interfaces of 3.5″ and 2.5″ hard disks.

SSD is able to replace the traditional mechanical hard drive to become the newest system disk which is the biggest credit to the NAND latency-free response speed, and this data in the SSD specifications using IOPS (random read and write) to indicate that the greater the value of IOPS indicates that the SSD in the system application of the “sensitivity” is also higher.

The reason for this phenomenon, the first may be caused by the motherboard chipset itself, some of the old motherboards only support 256MB memory capacity (i815 series only support 512MB), beyond the part, can not be recognised and used. Of course, there are also some cases is due to the motherboard can not support high memory particles caused by.

The solution is to replace the motherboard or memory. Also in some cases the problem can be solved by adjusting the insertion order of the memory.

Sometimes, after installing new memory sticks, the computer does not recognize them. This may be due to the fact that the memory sticks are not properly inserted into the slots or there is dirt on the slots. In this case, we should check if the memory sticks are inserted correctly and gently wipe the slot gold fingers with an eraser to ensure good contact with the slots.

No, it is not necessary or recommended to defrag an SSD. Since there are no physical disks, there is not need to organize the data in order to reduce seek time. Oreton SSDs have TRIM, which serves the same basic function to make your drive faster without subjecting the drive to the extra workload. Defragging an SSD will put undue wear and tear on the drive and may actually shorten its life.

The capacity is shown in “Megabyte” (same with Hard Disk Drive, 1MB = 1000KB). In Windows environment or DOS mode, 1MB equals to 1024 KB.  Therefore 1GB is approximate 953MB.

The actual available memory on the device is less than what is listed on the package. This is due to small discrepancies in file format and algorithms used by various operating systems. In addition, a portion of memory space is reserved for system files and data sectors for better performance.

NVMe stands for Non-Volatile Memory Express. Non-Volatile Memory means that it does not require power to retain information.NVMe takes advantage of pipeline-rich, random-access, memory-based storage. It provides significantly higher data transfer rates than traditional disk interfaces such as SAS and SATA.

The NVMe protocol can be used with most standard interfaces which includes M.2 / PCIe / and SATA express.

No, they are different; M.2 supports both SATA and PCIe storage interface options, while mSATA is SATA only. Physically, they look different and cannot be plugged into the same system connectors.

Self monitoring, analysis, and reporting technology (S.M.A.R.T.) is a built-in monitoring feature for regular hard drives and solid-state drives. It allows users to monitor the health status of their devices. This operation is achieved through monitoring software designed specifically for the S.M.A.R.T. function. All Oreton solid-state drives support S.M.A.R.T.

Paired memory may not necessarily need to be installed, but some higher-order motherboards have motherboards that support dual or four channels, which can (in some cases) significantly improve performance.

Reminder: If using two or four memories, their memory capacity must be the same, and it is recommended to use the same brand of memory to avoid a state of inability to power on.

No, the speed, voltage, and memory slot (or gold finger gap) of DDR3 and DDR2 are different.

Depending on your needs, increasing memory capacity can allow you to run multiple applications at the same time, but there may still be some differences in their operating speed. Suggestions are as follows

• Mostly used for browsing web pages and office documents, homework programs: 4GB or 8GB
• Mainly used for simple games and video playback: 8GB or 16GB
• Mainly used for drawing software or heavy game players: over 16GB

ECC (Error correcting code): When a storage device with this function encounters an error while accessing data, the device will automatically detect and fix the error to maintain normal system operation. This technology can increase the accuracy and security of data.

CAS latency, also known as CL value, refers to the amount of time a computer needs to wait before actually starting to read data from memory. The higher the CL value, the longer the delay time required, which usually increases with the increase of frequency. It is not the best choice to pursue a lower CL. For example, CL2 refers to the time required to access data in memory at two frequencies. Generally speaking, the smaller the CL value, the more advanced the process used, and the higher the requirements for the motherboard.

Dual channel is designed by the CPU architecture and operates in parallel. When connecting two memories, the bus width will reach 128 bits, and the difference will be known when calculating the memory width. After opening dual channels, the bandwidth can be doubled and the efficiency will also increase; As for whether it can be increased to twice the speed, according to testing, it seems impossible, but it is very helpful for improving memory performance. Depending on the characteristics of each motherboard, there are slight differences, which can be combined with overclocking to enjoy different performance experiences.

If paired with memory of different frequencies, the system will automatically run dual channel performance with the minimum frequency memory.
