There are several mainstream memory sockets now

I don't understand what you mean?

Many motherboards have three memory sockets.

Each motherboard can only use one model of memory.

The memory is divided into DDR and DDR2, and the frequency is 266, 333, 400, 533, and 600.

At present, there are three kinds of mainstream memory: SDRAM, DDR and memory can only be used on P3 motherboards, i845 and KT133A chipsets, and the most common SDRAM memory standard specifications are PC-100 and PC-133, among which PC-133 is the most commonly used, but with the introduction of DDR memory, SDRAM memory is basically on the verge of elimination.

DDR memory is the most mainstream memory on the market at present, mainly because of its high cost performance, and almost all motherboards on the market now support DDR memory. The only ones that have been approved by the International JEDEC (Joint Electron Device Engineering Council) are DDR200, DDR266, DDR333 and DDR400. Generally speaking, the high-end is always compatible with the low-end, but there are exceptions to this, such as the 915P chipset can not support DDR200 memory, which should be noted by the majority of users when choosing.

And the quality of memory is also mixed, sometimes even the author can't distinguish it, so it's best to have a knowledgeable person present when buying memory, generally speaking, choose Kingston, Kingmax, Infineon, original Hyundai, original Samsung, Corsair, Micron (Micron), Apacer, Transcend (Transcend), Twinmos (Qinmao), ADATA (A-Data) and other brands are always right, ** generally between 300-320.

DDRII memory specifications that will be popular in 2005 are popular because they can produce DDRII products without replacing DDR production line equipment, and are popular with chip manufacturers, and its bandwidth and transfer rate are much faster than DDR memory, which is cheaper than RAMBUS memory in addition. Therefore, it has been welcomed by most hardware manufacturers, including Intel, but because the current production capacity and sales have not reached a certain base, the current DDRII memory is still relatively expensive compared to DDR memory, and now only Intel 9X5 series, K8T890 supports DDRII memory specifications, so it will take a little more time for DDRII memory to be popularized on a large scale.

Memory slot: This is the slot on the motherboard that is used to store hardware memory modules.

There are four types: SD, DDR, DDR2, and DDR3.

But there are frequencies!
