I want to change the memory, please point to the high!!

Yours is the memory of the DDR generation, with frequencies of 266,333,400, respectively

High-frequency memory can be used at reduced frequency, and there are currently no 266,333 memory on the market, so you can use the memory of DDR400 normally, but it is best to sell your current 266 and replace it with two DDR400 of the same specificationFor example, Kingston memory of 512 2.

In addition, DDR533,667,800 is DDRII memory and cannot be mixed with DDR generation.

Good memory with Kingston.

Add two DDR2 800's.

It's much faster.

And it's not expensive.

Why don't you have a 133M CPU now, it's all antique, you play one less zero, now the memory must buy DDR2 soon Kingston's good.

PC2100 is DDR266 belongs to the first generation of DDR memory, you can change the root DDR400 512 memory to try. That's it for the highest support, 667 800 don't even have to think about it.

It is recommended to change to a DDR2 motherboard with 400 pieces + 1GDR2 memory with 120 pieces.

If you want a DDR4, the performance will not go up, and it will be expensive, and it will be annoying to upgrade it in the future.

Nowadays, DDR memory is also expensive, and the performance is far inferior to DDR2.

Don't listen to their nonsense, if you use DDR2 the consequences are either your memory burns or you ruin the motherboard. According to your configuration, the external frequency of your CPU is 133, which means that your motherboard must be relatively old. It is recommended that you buy the same memory as your memory brand.

Because your external frequency is 133 and the working frequency of the memory is twice that of the CPU external frequency, so your current memory should be DDR 266, remember to remember, you must buy the same brand as your current memory model, you didn't say the brand and model of your motherboard, so I can't give you more advice.

Your motherboard is relatively old, what is the maximum capacity of a single memory supported by the motherboard in the manual? (If it can support 512MB, it's the best) you go to your motherboard's manufacturer** to see if there is an update to the BIOS, if there is an improvement in the content of the update, the motherboard's support for the CPU, if there is, you can flash the BIOS, but flashing the BIOS has a certain danger. (If you won't, don't mess around, otherwise it will damage the motherboard) after successful flashing.

If the motherboard can support the CPU external frequency 200, and the front-end bus is 800, then you can change the CPU, and the single-core CPU is cheaper now. Changed the CPU and then the memory. Because the CPU external frequency is 200, you choose DDR 400 512MB to buy two, it is not expensive, and 2 is 150-180

Kingston. ddr400

It's the perfect fit for you.

The DDR 400 3200 memory can be used on your motherboard. Of course, the larger the memory, the better.
