2gb + 1gb in dual channel -possible?

[nO}{8]

Ive got 2x1gb sticks and also have 2x512mb sticks, can I use them both in my 4 available slots in dual channel? Will I have to run 2t or something?

one is rated at 3/4/4/8 and the other 2.5/4/4/8

No, as far as I know you can only have two identical sticks in there to run in dual channel mode, although I could be wrong.

Try it!,but i think you`re going to lose some performance..I think the mem will default to slowest which will be 3 timing in 3/4/4/8 and 2t.

4 sticks indeed means running at 2T and you may have to set the memoryspeed manually to 1:1

Also overclocking might be limited as you are limited by the slowest stick.

The disadvantage of 2T is ~5%-10% depending on the application but the advantage is that in situations where 1Gb isn't enough 2Gb will be faster.
