Single sided or double sided RAM?

[Sir Phoenixx]

I just got 2 512mb sticks to go with my current 2 512mb sticks. All 4 sticks are Corsair 512mb DDR400 PC3200 CL 2.5 184pin, but 2 of them are single sided, and the other 2 are double sided.

I can run either set in dual channel mode, or any combination of 1 single sided and 1 double sided in single channel mode, but I can't run all 4 at the same time in any order at all.

EDIT: Nevermind, switched to 2T and all 4 sticks work and are all running in dual channel.

Where did you buy them? Anyway to get the same (single or double sided) as your older ones (assuming you could then run in 1T)?

2T really slowes performance compared to 1T if you can help it.

Although 2T dual channel memory would probably perform better with most apps than 1T single channel unless it was a program that really liked lower latencies (winzip/winrar).
Glad you got it at least working in dual channel.
