This article explains from a technical perspective<\/strong> why mixing RAM modules can degrade performance and how to choose memory correctly to avoid pitfalls.<\/p>\n No matter how fast your memory sticks are rated, the actual speed is often determined by the slowest component in the system<\/strong>.<\/p>\n Mixing RAM causes issues because the system must make all modules work together under a shared set of parameters:<\/p>\n For example, mixing 2666MHz + 3200MHz will force the system to run at 2666MHz. The system will adopt the loosest timing among the modules.
