Regarding the problem of memory frequency, ask for the difference between high and low memory freque

The first thing to say is that the DDR memory specification does not have DDR300, the closest to it is DDR333, if you buy 512M DDR 400 specification memory and your 256M DDR266 memory at the same time.

If used, the 512M DDR 400 will be clocked down to 512M DDR 266 to be used, DDR333.

The same will be downclocked to DDR 266 to use, since it is the same frequency memory as long as the capacity is the same.

The performance will be about the same, but the current DDR 266 specification memory is mostly seen in the second-hand market, in order to.

To avoid buying problematic memory, you still better buy a 512M DDR 400.

Will go according to the lowest frequency!

For the sake of stability, it is necessary to reduce the 400 to 266 to use. Also, different memory particles will be incompatible. Since your memory is 266, I think your CPU has been bought for a long time, and the external frequency is estimated to be 100 or 133, which is just right with 266.

I think 266's is enough. Since it was summer, I dropped my sempron2500+ from 166 to 133 in frequency. The memory is automatically adjusted to 133 according to the CPU.

But it's no problem playing normal games. So I say, you should pay more attention to compatibility, stability.

Exclusion of incompatibilities.

The motherboard automatically locks the memory at the lowest frequency of any memory module. In your case, the old memory is 266, then if you change any memory with a higher frequency than 266, it will automatically drop to 266.

Therefore, in the current situation, what should be given up must be given up, and the old can be abandoned.

3What is the difference between the frequency of all memory? Take a look at the Bogo computer to explain it to you!

The frequency of the memory module represents the highest operating frequency that the memory can achieve, and to some extent, the speed at which the memory accesses data.

The main factors that affect a memory module are: size, model, and frequency. The latest model is DDR4, and there are DDR3, DDR2 and DDR, all of which are not as fast as DDR4.

The higher the frequency, the better, usually 1600MHz and 1333MHz.

Now the mainstream DDR2 memory is DDR2 800, the frequency of the memory is related to the rate of transmission, it is recommended to use two 1G 800 memory to form 2G memory is enough, playing 3D games has a lot to do with the graphics card, if there is no good graphics card, it is recommended to buy a suitable graphics card.

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.
