The 4G memory module only shows how to deal with 2G

XP only supports 2G memory, and it is useless not to display more.

W7 with 2G than XP2G card. With XP, no matter how good you use the 1G network, it is also a card. With 2G, it's fine.

W7 will use 4G, the same network will not be stuck. In the same network in W7, you use a 2G card, and you will not get a card with 4G.

If you simply go to school and work, you can use 2G.

A 2G computer memory will have a bit more than a 4G computer memory card.

Memory is one of the most important components of a computer, and it is the bridge that communicates with the CPU. The running of all programs in the computer takes place in memory, so the performance of the memory has a very large impact on the computer. Memory, also known as internal memory, is used to temporarily store computing data in the CPU and exchange data with external memory such as hard disks.

As long as the computer is running, the CPU will transfer the data that needs to be calculated to the memory for calculation, and when the operation is completed, the CPU will send the result out, and the operation of the memory also determines the stable operation of the computer. Memory is made up of parts such as memory chips, circuit boards, gold fingers, etc. There are many types of memory, which can be divided into main memory and auxiliary memory according to their use, and the main memory is also known as internal memory (referred to as memory, which is called memory in Hong Kong and Taiwan).

If the CPU of the computer is very strong and the memory is very small, the CPU will process too fast, the data in the memory will be in short supply, and the situation of the CPU waiting for memory is generally called a card.

If you guess correctly, the 1600 one should be 4g. The 2g one is 1333.

Then that's easy to explain.

The northbridge chip for this motherboard is the G41. This is the boss of the block 775 interface. The memory controller is not inside the CPU, but in the Northbridge. The memory frequencies supported by the G41 are the long-lost DDR3 800 and DDR.

Obviously, the 1600 strip is no longer within the compatible range. We can think that it can't be used.

However, quite a bit of memory will run in buckdown mode. For example, the memory module of 1333 can run at frequency 1066.

This generally requires 2 conditions:

The motherboard supports this frequency of memory. Including the motherboard can recognize the SPD of this memory and can be applied, the memory module itself can work stably at lower frequencies.

If the frequency of the memory modules used together is different, it will not form a dual channel. Whether the timing is compatible with high-frequency memory modules.

We usually force the memory manager to use a certain frequency by swapping memory slots. Usually the slot near the CPU or the north bridge is the main slot. The system determines the frequency of subsequent slots based on the frequency of the primary slot.

You did do this, but it didn't work. We can tell that this motherboard really can't use memory modules at this frequency.

Another thing to explain is why Master Lu can recognize 6G memory. The operating system does not directly show the actual size of the physical memory, but rather the actual usable memory capacity. In other words, another 4G memory module system can read out the SPD information, but it is judged to be unavailable.

Then the operating system won't show it to you.

Software is the hardware that is shown to you as it actually exists, but not always available. Therefore, I have always been disgusted with this kind of junk software of Master Lu. This junk software keeps giving users misinformation.

The maximum possible amount of your memory is not at the same frequency and cannot form a dual channel.

1. Either it is a problem with the system itself, try to replace the system once;

2. Either you have a problem with the strip later, you can try it on other machines.

The computer checked the 2G and 4G memory modules, and the overall composition is 6G memory, if the system only shows 2G memory, then a 64-bit system should be installed.

Reason: The mainstream system of the computer (win7, win8, win10 system) is divided into 32-bit and 64-bit. A 32-bit system can only recognize a maximum of about 3G of memory, and if the computer's memory is 4G or larger, you need to use a 64-bit system to make all the memory performance.

You plug in a single 4G and try it. If it doesn't turn on, it proves that your computer is not compatible with that 4GB of RAM.

Call the BIOS limit, reset the BIOS, or upgrade the BIOS.
