My computer s memory frequency is 400, can I use the current frequency of 800 memory?

You can't use 800, 400 should be DDR1, 800 is DDR2

It depends on the motherboard. Look at your motherboard, it supports 800. It is not supported to change the motherboard.

No way! Yes for the motherboard corresponding! Unless you change the motherboard.

It is possible to change the motherboard, one slot to insert 800, and one slot to insert 400, but I doubt such stability.

Cao is different, it can't be plugged in at all, unless you change the motherboard, change the CPU

This is because the default setting of the motherboard is to run a frequency of 2133 MHz, and I am afraid that the frequency is too high to support ordinary memory.

If you are sure that the memory supports 3000MHz, you can go to the BIOS interface (press the delete key or any other key when booting, the screen prompt), find the overclocking interface, modify the memory frequency (RAM frequency), and change it to 3000MHz.

Memory Overfrequency Method:

1. On the Boot button panel, enter the BIOS system and select the first item (M i T).

2. Use the mobile keys on the keyboard to select (advanced memory settings).

3. According to the above prompts, you can use the plus key to set the option value.

4. Select the memory frequency and the plus sign on the keyboard.

5. After pressing the plus key, the memory frequency will increase until you select the desired bay rate.

6. Finally, select the upper right corner of the interface (Save & Leave).

Because of 1600 memory.

Come, this ** its base frequency is 800.

1. At present, the internal DU memory of BAI is called DDR, which is simply understood as double. The motherboard gives a base DAO base frequency, 800, and then the memory runs double, which becomes 1600.

2. It can be inferred from this that if it is 1333 memory, the actual base frequency is 667. The same goes for other memory.

DDR=Double Data Rate. Strictly speaking, DDR should be called DDR SDRAM, which is used to being called DDR, where SDRAM is the abbreviation of Synchronous Dynamic Random Access Memory, that is, Synchronous Dynamic Random Access Memory. DDR SDRAM is the abbreviation of Double Data Rate SDRAM, which means Double Rate Synchronous Dynamic Random Access Memory.

DDR memory is developed on the basis of SDRAM memory, and the SDRAM production system is still used, so for memory manufacturers, only a little improvement of the equipment used to manufacture ordinary SDRAM can realize the production of DDR memory, which can effectively reduce costs.

It can support DDR II 800, but it is recommended to use 667 when upgrading, and it is best to use the same frequency of the two memories; If you abandon the original one, it is also possible to upgrade two 2G DDR II 800 at the same time.

800 belongs to the second generation of memory, you can see if the middle part of the memory slot is written, the second generation of memory is.

You can check the parameters of the motherboard and the memory it supports, but I guess your computer's motherboard should only support DDR2 667MHz, but you can also use 800MHz memory, but if you do, it will reduce the frequency.

In other words, if you plug in an 800-frequency memory module, your motherboard only supports a 667-frequency memory module, so the final memory frequency can only be 667 at most. This is because high-frequency memory modules are backward compatible with low-frequency memory sockets.

It should also be noted that if your motherboard only supports DDR2, you can only use DDR2, not DDR3.

Purchase suggestion: Try to choose a big brand of memory to avoid poor compatibility and other situations such as blue screen on the computer.
