Ask that I want to trade in certificate of deposit, can change into two in 512M DDR the certificate of deposit? Thanks the direction!
May, but in the present market can be able to buy you could also use only then DDR400.Not question ~~~ Changes into DDR400 512MB to be possible.
Cannot trade DDR2,
Certainly must pay attention.
DDR2 and the DDR needle foot number is dissimilar.Just looked up your motherboard, is the compatible DDR1 memory.May add two 512M the DDR1 memory, generally the DDR1 400 words are quite good, but the present did not know that also has sells out does not have.Is first definite the memory model, then buys two 512 then.————————————— DDR1 400 words, because the present possibly does not produce, relatively expensive somewhat, will want about probably 300.May.
