Dual channel help from gurus!

[castcore]

Ok guys, thanks in advance but I really need help here.


would like to upgrade my current Dell 9150 Pentium D 3.2ghz , 2gb to 3 GB. I now have 2 1GB sticks running in dual channel. I know I can stay in dual channel even with 1gb+512mb(channel 1) and 1gb+512mb(channel 2) but my question is, do the 512mb sticks have to be the same specs(ie ram chips, brand) as the 2 1GB sticks?

Or am I even correct I can still run dual channel like this?


What if I get 3 1GB sticks , all the same specs? Will that work? Thanks in advance

You can probably run dual channel in that configuration, however you just have to make sure that the timings/voltage is able to run on all sticks.

You can't run dual channel with 3 sticks except if you have a special AMD board (S939) that came with 3 available slots where you can put channel one 2x512 and channel two 1gb.

Anyhow, your channel 1 is 2x1gb and second is 2x512.

I meant dual channel in matched pairs (2x1GB and 2x512mb)....not in 3x1GB
