One 2G RAM and one 512M RAM

The problem is this! "The old machine was originally a 512m667 Jintai memory", which determines that your motherboard is recognized by default with a frequency of 667 strips, when you plug in 2G ADATA 800, because it is 800, so you can't use it! And although you can use both plugs in, your ADATA 800 is actually recognized as 667 (which is also the reason why the CPU is unstable)!

The frequencies that everyone is talking about are different and incompatible because of this! There are two ways to solve it: one is to buy another 667 (the so-called capacity is asked, the key is the frequency), and you can use it at the same time!

2: Modify the default setting of the motherboard BIOS hardware to 800, so that your 667 can not be used (high-energy recognition is the bottom, but the bottom cannot be recognized as high, haha!). You can only use 2G ADATA 800!

Let's use the second method! 2G is enough if you don't play big games!

NF5 can definitely support DDR800.

It's just that there is a problem with your memory itself or it is incompatible with this board, try to buy it, or get it to a friend**Try it, if your friend can use it normally, it proves that it is incompatible.

It stands to reason that it shouldn't, when you plug in 2GB memory alone, one can be plugged into the 512M memory position, and the other is to power the CMOS and then start the machine to see if it will start normally!

Because some motherboards will memorize the hardware information of the system, after you add 2GB alone, the machine will also press 512M to record the information, which may cause boot failure!

If you work together and the capacity is about 1, it means that the memory recognition is fine, and if it can run stably, it means that the compatibility is no problem!

1. Clean the memory slots;

2. Give the BIOS a charge, that is, take the BIOS battery;

3. Change the position of the two strips;

If it doesn't work, it should be incompatible, one is a brand conflict, and the other may be a difference in frequency; Then I have to change to another machine to see if it works, and the possibility of changing is basically non-existent.

Your 2G RAM is not compatible with the motherboard! 2G and 512 words 512 or 2G are not available! Anyway, there is one that doesn't work! To add only 512m667 Kintek.
