The CPU and memory frequency are only half of what they actually are

It's not a dual-core patch thing at all, and dual-core patches have nothing to do with frequency.

The memory is indeed normal.

Your CPU is also normal, because AMD has a technology called cool and quiet (cool &quiet), when the CPU is not in a high load state, it will automatically reduce the frequency, so as to achieve the purpose of energy conservation and environmental protection, this technology is turned on by default, you can choose to enter the BIOS to turn off the item, you can do the following specific operation: how to turn off cool and quiet. After turning it off, your CPU-Z display will be normal.

Or if you suddenly open a large program, you will find that the CPU frequency has become normal.

Hit the dual-core patch from the ground up, suspect that you are missing the patch.

Memory dram is normal.

The so-called 800 refers to 800 working up and down at the same time, and it is still 400 in one direction, and CPU-Z detects it in one direction.

It doesn't seem to be clear ...

A quick explanation.

The so-called DDR2 800 refers to the fact that the memory works in both directions, one up and down, one way works according to the 400 frequency, and the two add up to 800, which is what it means.

The low CPU frequency is due to AMD's cool and quiet function, which automatically reduces the frequency when idle to save power.

The memory is actually running at a frequency of 400 because DDR2 transmits data 4 times in one clock cycle, which is equivalent to DDR800

Because of the memory frequency shown in CPU-Z.

is the real frequency, and the frequency that is usually said is the equivalent frequency, which happens to be the real frequency x2.

Memory clock speed and CPU clock speed.

Similarly, it is customary to use it to represent the speed of 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.

<> what you see is normal, DDR3 memory is all double the data transfer rate.

So the physical frequency is 800

The equivalent frequency is 800*2=1600

This is mine, frequency 667

So my memory is DDR3 1333

You can rest assured.

The nominal frequency of the memory refers to the frequency of dual channels, such as 1600MHz for DDR3. When checked with the CPU Z program, the display frequency is 800MHz, which is exactly half the frequency of the dual channel.

800x2 = 1600MHz, this memory is double data rate

DDR for short).

When some friends use CPUZ to test the memory frequency, they find that their CPUZ memory frequency is only half, I don't know why, I am worried that the memory is broken, in fact, this is a normal phenomenon, not Yan Shenchun represents a problem.

1. In fact, it is normal that the memory frequency of CPUZ is only half.

2. Coarse resistance because most of themDDR4 is bidirectional, and Hyo-amOnly one-way frequencies are displayed in CPUZ

3. So the real memory frequency only needs to multiply the memory frequency of CPUZ by 2.

4. If you are not at ease, you can enter".biosUnder Settingsmain"Menu.

5. You can check your real memory frequency below.
