First of all, I want to ask you.
Both RAMs are installed.
Whether the system can operate normally.
and identified to 2 heel memory.
There is no blue screen appearing.
Memory error. Problems such as crashes?
If not. That proves that both are good.
If something goes wrong.
You can use the alternate method.
Unplug the memory alternately.
Try which one is having problems.

AwardBIOS Self-Test Bell Meaning:
1 Short: The system starts normally. Congratulations, there is nothing wrong with your machine.
2 Short: General error, please enter CMOS
setup, resetting the incorrect option.
1 long and 1 short: There is an error with the RAM or motherboard. Try to change the memory, if it still doesn't work, you have to change the motherboard.
1 long and 2 short: The display or graphics card is wrong.
1 long and 3 short: The keyboard controller is wrong. Check the motherboard.
1 long and 9 short: motherboard flash
RAM or EPROM error, BIOS corruption. Try a different block of flashram.
Constant ringing (long sound): The memory module is not plugged in tightly or is damaged. If it still doesn't work, you can only replace a memory module.
Ringing: The power supply and monitor are not properly connected to the graphics card. Check all the plugs.

Here can be solved inMaster Luto detect your own computerMemory sticksGood or bad, here's how to do it.
1. First of all, click [Start Installation] in the computer to install Master Lu, as shown in the figure below.
2. After installation, Master Lu will be automatically opened, and click [Start Physical Examination] in the window.
3. After the physical examination is completed, scroll down, find and click [Hardware Information], as shown in the figure below.
4. Finally, under the hardware information, if you can see the memory information of your computer, it means that the memory module is good, if it is not displayed, it means that the memory module is broken.

1. Judge the memory module.
Whether it is in good contact with the slots on the motherboard. Sometimes due to too much dust inside the case, the memory module is in poor contact with the socket. At this time, you can take out the memory module, use an eraser or brush to sweep the dust on it, and at the same time clean the dust in the memory slot, and then plug in the memory module and restart the computer;
2. Secondly, judge whether there is a problem with the slot. In general, motherboards provide 2 or 3 memory slots, and you can try changing the memory module to another slot. Thirdly, if the computer upgrade has done a memory expansion, determine whether a memory module that is not compatible with the motherboard is selected.
At this point, you can try to change the memory module or upgrade the motherboard's BIOS directly. If you add another memory module to the original memory module, you need to determine whether the two memory modules are of the same brand and whether they are compatible. In general, it is only necessary to ensure that the model of the two memory modules is the same;
3. If the memory is damaged, there will be an alarm sound when it is turned on. If the damage is unstable, it can only be experienced in use, for example, to rule out the factors of the system, often blue screen.
Reboot, or boot reboot, blue screen. Wait a minute. Another way to do this is to use software testing.
It's time-consuming, though. Go to the Internet and find an everest to take the test.

If the memory module is damaged, the computer will not start, the blue screen, and the computer will freeze.
The memory module is a very important component in the computer, which is easy to be accidentally damaged, and when the memory module is faulty, the computer will fail to start, often crash, blue screen, and the software will not be opened on the wrong display. You can send the computer to the repair place and have the computer overhauled by professionals.
DDR3 is definitely DDR2 good, but the slots are not the same, that is to say, two slots cannot be inserted into the same slot. If you originally support DDR2 800, then you can only change DDR2. If the motherboard is a mix of DDR2 and DDR3, remember to correspond.
The speed of adding memory will be felt.
Mixed plugging is possible, as long as the parameters of the two memories are about the same, in fact, as long as it is not dual-channel, the parameters of DDR memory are similar, generally put the latest maximum capacity in bank0, and then bank1, that is, your 512MDDR400 is placed in bank0 slot (the one closest to the CPU), and 256DDR333 is placed in bank1. Of course, if you mix and plug in, the DDR400 will automatically drop to 333 to run, but the increase in capacity can make up for the lack of speed, and the speed is almost unfelt, if you are running large software, large memory will definitely prevail. You can tell by the speed at which you open a word file. >>>More
Memory is an indispensable component of a computer (PC, MCU). Unlike dispensable external memory, memory is a component that reads and writes on a bus; Memory is more than just a data warehouse. In addition to a small number of indispensable programs in the operating system to reside in memory, the programs we usually use, such as Windows, Linux and other system software, including typing software, game software, etc., although a large amount of data including programs are placed on external memory devices such as tapes, disks, optical discs, mobile disks, etc., but any data in external memory can only be really used when transferred into memory. >>>More
