Re: two 256mbs dont work 2getha ?

Any motherboard you buy, you musn't mix branded modules, buy a matched pair of the same size and same speed and type.. This is the correct way:

dimm 1 = xms corsair 3200LL = 512mb
dimm 2 = xms corsair 3200LL = 256mb

This is the wrong way below

dimm 1 = xms corsair 3200LL = 256mb
dimm 2 = xms corsair 3200LL = 512mb

motherboard will only register the largest size first
But if you want dual channel performance you are best to buy a matched pair of the same type and size e.g XMS corsair 3200LL 2 x 512mb modules
my matched pair is 1024-3700PT a gig in total means 2 x 512mb modules

His mainboard doesn't support dual channel memory.

As was stated... Never mix match different modules of RAM. You are only asking for problems ESPECIALLY if you have a dual channel board!!! Glad you managed to fix your problem though!!!
