There is a detailed configuration for computer plus memory modules

Buy a brand of memory, and you can generally use it.

Although DDR400 memory is generally available on the market now, many CPUs at that time, especially Intel's, had the default maximum working frequency of the memory determined by the external frequency of the CPU, and many memories were used for frequency reduction.

Generally, you can use the memory when you buy it, but in the case of instability, the motherboard sets the memory working frequency according to the SPD value of the new memory, and you can adjust it to the same frequency as the old memory in the BIOS.

Then there is the memory quality is not good, and it is indeed not compatible with your motherboard, very little.

1 PC2700 (166 MHz) RAM is DDR 333 RAM. You can buy DDR 333 RAM or DDR 400 RAM (DDR 400 RAM is compatible with DDR 333 RAM).

It can definitely be bought, but it is only 2 lots.

If you can't buy it, there's a best way.

It's to sell the old one and buy the new one, depending on how often your motherboard supports it. Generally, DDR400 1G will do!

This machine is too old, it is better to spend 2000 to replace the hardware on the motherboard.

My classmate used 1700 to change it, and it was very cool to play anything.

Your memory is only DDR1, and now it's basically DDR2, and you can buy a DDR333.

There are definitely 2 lot markets.

Call the customer service of the same party and ask them to provide you with how much memory your machine master supports.

Of course you can buy it, but you have to buy it second-hand!

Buy it at the second-hand market.

The model and capacity should be the same.

Before configuring computer memory, you must first determine the maximum memory capacity that can be supported by the computer system and motherboard, the number of remaining memory slots on the motherboard, and the model specifications of the supported memory.

The specific operation steps are as follows: detect the maximum memory capacity that the computer can support: the operating system is different, the motherboard is different, then the maximum memory capacity supported by it is also different, such as win 32-bit system, the highest is to support the left and right memory, no matter how much your motherboard supports at most, but the maximum 32-bit system can only support the left and right memory.

If you have more than 4G of RAM or just 4G, install a 64-bit operating system for more memory support and faster processing on your PC. Keep in mind that hardware + operating system determines the maximum memory supported.

The specific detection methods are as follows:

1. Open the "Start" menu and click the "Run" button.

2. Type "cmd" in the pop-up window, and then confirm or press enter.

3. Enter "wmic memphysical get maxcapacity" in the command window and press enter.

4. Then the computer will give a string of numbers in kilobytes. Convert this string of numbers into common gigabyte units. The conversion is:

The resulting number (divided) by 1024 (divided by) 1024": This computer gets a string of 16,777,216k bytes, which is 16GB divided by 1024 and divided by 1024. In other words, the hardware of this computer, and the system that is installed, supports a maximum capacity of 16GB of memory.
