What exactly controls the computer's memory frequency? Does the motherboard limit the memory frequency?

Hello everyone, I'm a craftsman. Friends often ask me: My CPU is written to support 2666 frequency memory, so if I buy 3200, it will be a waste, and if I see that the motherboard supports more than 4000 memory, then can I buy a higher one? ? This all reveals that who decides the frequency of memory? How much can the high frequency performance improve? There is no concept at all. Today, Xiaojiang will introduce some small knowledge of memory to you. First of all, let's understand what is the memory frequency? Electronic devices will run at a certain frequency when they are working. The higher the frequency, the stronger the performance, just like stepping on the accelerator when driving. Then, what we usually call overclocking is to increase the factory frequency and make it overload. However, this operation is dangerous, because the frequency increases, the voltage and heat will also increase, and the extreme situation may also burn the hardware. Then there are several key factors that limit the frequency of memory. ①: The marked frequency of the memory module itself ②: The default memory frequency of the CPU ③: The default frequency of the motherboard ④: The frequency of the overclocked memory of the motherboard The lowest of the first three items shall prevail. For example, if you buy a 12th generation i3-12100F processor and the motherboard is H610, then when you buy a 3200 memory and plug it directly, the memory display is likely to be 2400 or 2666, which is the default memory frequency of the motherboard. But when you turn on XMP (official memory overclocking), the memory can run to 3200, which means that the motherboard and CPU can support higher, but because the SA voltage of the non-K version of this generation of processors is locked, the memory exceeding 3200 will be It is unstable, so it can only go up to 3200, which is the limit of the CPU. Of course, if you are using Intel's K-series processors and Z-series motherboards, or AMD's Ryzen series, the memory can also be overclocked to a higher frequency. For example, the 3200 frequency memory you purchased can work at 3400/3600 or even higher after overclocking. At this time, it depends on how high your motherboard can support. So the last question: how much does high-frequency memory improve performance? Here we will directly look at the picture and talk. The following are some mainstream 3A large-scale stand-alone games. Tomb Raider: Shadow Cyberpunk 2077 Wilderness 2 Microsoft Flight It can be seen that for this large-scale 3A stand-alone game, the impact of the number of game frames and the number of frames is very small, the improvement is there, but not very big . It is more intuitive to upgrade the CPU and graphics card. In the end, let's sum up the old saying: what fits is the best. If you are an i3, why is the last 4000 frequency necessary? In the same way, if you use an i9, is the last frequency of 2666 a waste of CPU? The performance of the host follows the principle of wooden barrels, and the overall improvement can only be achieved if everyone matches and improves together.
