Computer Memory Speed Chart

I choose to post this computer RAM chart is because I find that sometime I forgot what the memory speed for a specific RAM type is.

The reason of posting this chart is convenient anyone who needs to configure the computer RAM speed. Let say you have a RAM with PC-2100 but you misconfigure it to run in 400 MHz, it may not provide you as fast as you set and perhaps will shorten the RAM life time. The other way round, if the motherboard only can support up to 400 MHz then it is useless to buy a 500 MHz or faster RAM installed for your computer. This is because no matter how fast the memory you installed the motherboard will automatic downgrade it to 400 MHz or the maximum speed that the motherboard can support.
