Questions about memory frequency. Is it good to have a high memory frequency?

First of all, the memory of DDR2 800, it runs at a frequency of 400, and 800 is just the equivalent frequency.

DDR2 800 memory, which means that the highest equivalent frequency of this memory is 800, if your motherboard only supports 667 memory, you plug in 800 to go up, the maximum equivalent frequency of this memory can only reach 667, all of the above are under the condition of not overclocking. The actual working frequency of the memory is determined by the ratio of the CPU external frequency and the CPU external frequency to the memory running frequency, which is the synchronous asynchronous problem you mentioned. For example, if the CPU of the E2200 is 200 and the memory module is DDR2 800, if the ratio of CPU frequency to memory frequency is set to 1:

1, then the actual working frequency of this memory is 200, and the equivalent frequency is 400, which is called memory synchronization, so that the memory of DDR2 800 is used as DDR2 400. If it is set to 1:2, then the actual working frequency of this memory is 400, and the equivalent frequency is 800, which is called memory asynchronous, so that DDR2 800 memory is not wasted.

This ratio is asynchronous as long as it is not 1:1. If you set it to 1:

3,Then the memory is going to be overclocked,To work at 600,The equivalent frequency is 1200,At present, dd2 800 memory can be overclocked to 1000, which is good,1100 is very little,1200 is basically nothing。。。

The number of high-frequency memories that the motherboard can support is determined by the Northbridge chip. In general, if you buy 800 memory, and the motherboard can also support 800, then the motherboard will make the memory work at the equivalent frequency of 800 by default; If you buy 800 memory, the motherboard can only support 667, then the motherboard will make the memory work at the equivalent frequency of 667 by default; If your motherboard supports 800 RAM and you buy 667, then the motherboard will make the RAM work at the equivalent frequency of 667 by default.

That's popular enough, right? Hehe.

Take the strip off and see how much is written on it. Try a different machine. It may be a false positive, is CPU-Z the latest version?

Usually not.

Isn't it your IDE that is open-cored.

Generally, open-core ones need to be declocked memory.

If you don't downclock, you won't go up.

Fakes are scammed in general impossible.

You post your picture for everyone to see.

Then there's your CPU-Z and your BIOS configuration diagram.

This way everyone can help you more.

It's capacity that matters, but that doesn't mean frequency isn't important. Memory capacity refers to the storage capacity of the memory module, which is a key parameter of the memory module. The memory capacity is measured in MB and can be abbreviated as M.

The capacity of the memory is generally 2 times the whole power, such as 64MB, 128MB, 256MB, etc., generally speaking, the larger the memory capacity, the more conducive to the operation of the system.

Like the CPU frequency, the memory frequency is customarily used to indicate the speed of the memory, which represents the highest operating frequency that the memory can achieve. The memory clock speed is measured in MHz (megahertz).

The higher the main frequency of the memory, the faster the memory can achieve. The main frequency of the memory determines the maximum frequency at which the memory can work properly. At present, the more mainstream memory frequency chambers are 333MHz and 400MHz DDR memory, and 533MHz and 667MHz DDR2 memory.

Higher memory frequency is not always better, and too high a frequency will not only result in wasted performance, but also increase cost.

Theoretically, the operating frequency of the memory is equivalent to the processing speed of the memory, and the higher the frequency, the faster the processing speed and the better the performance. If you're using DDR2 or DDR3 memory, DDR4 memory will definitely perform much better than the first two.

However, with the development of technology, the performance of memory has improved significantly, and it is difficult to become a shortcoming that restricts the performance of computers. Especially after the advent of DDR4 memory, most users usually have excess memory performance.

In addition, when purchasing memory, be sure to refer to two parameters, namely the type of memory supported by the motherboard and the working frequency, and the memory working frequency supported by the CPU. Usually, the frequencies supported by the CPU and motherboard will be matched to avoid waste.

The performance resources of the memory are provided to the CPU through the motherboard, and the motherboard provides a transmission channel, so no matter how high the memory frequency is, try not to exceed the upper limit of the working frequency supported by the motherboard.

For example, if the motherboard supports 2133MHz, if you use 2400 memory, the memory will be downclocked to 2133 and will not work at 2400. But if the motherboard can support overclocking up to 2400 or even 2666, then there is no problem and there will be no performance waste, while there is a difference between the memory of the 2133 and the ** in the **.

In terms of CPU performance, there is generally no need to worry about the memory frequency slowing down the processing speed of the CPU, but only whether the memory capacity is sufficient and whether it is a dual-channel.

In summary, in actual use, the higher the memory frequency, the better, and too high a frequency will not only cause performance waste, but also increase costs. Generally speaking, choosing low-frequency memory is enough to ensure that the computer hardware plays to the ideal state, after all, most high-frequency memory can only be used at reduced frequency.

The motherboard Z590-F can overclock the memory, but whether it can exceed 3200 depends on the memory itself.

Use CPU-Z to detect the memory SPD first, if the memory isxmpOverclocking strip, there is x***200 timing (as shown below), enter the motherboard BIOS to enable XMP, you can exceed the frequency of 3200.

If the test results are detected, several sets of memory timings are all the samejedec, this is the general strip memory, the motherboard BIOS will not be able to set XMP, the memory frequency can only get the greatest common divisor with the CPU, JEDEC1163 1200 1333 timing, running at 2133 2400 2666MHz.
