I opened up my son's computer last night (24 hours or so before this post) to check a noisy fan. His board (which is actually using my old P4 Hyperthreading 3 GHz CPU) also supports dual channel & has 2 different pairs of RAM sticks. I noticed hat it too had the RAM installed with matching pairs side by side. So I swapped the sticks appropriately & now its RAM pairs match the colours. I don't know if you have to change anything in the BIOS for ASUS mobos to "activate" dual channel? Or does it take effect automatically?

Anyway his recent average credit was 362 when I did this. So let's see if it changes much going forward.

True but I'll try to find more info on this.
