I was having difficulties getting my Q6600 system stable at a 3.2 GHz overclock,after a 2GB to 4GB memory upgrade (which is FSB=356 X 9 on my Asus P5K motherboard).Then, I tried selecting DDR2 800MHZ memory in the BIOS instead of leaving it on Auto.This has resulted in a stable system with memory running at 6:5 X FSB which amounts to 854 MHz.Before the memory upgrade, I was running memory at 1:1 X FSB which I thought was the optimum setting.Is there any reason to want to revert to a 1:1 setting, or is 6:5 (which is faster) actually better?

Is there any reason to want to revert to a 1:1 setting, or is 6:5 (which is faster) actually better?

After reading up on this, it would appear that the opinions are split: Some swear by 1:1 and otherssay "go as fast as your memory will go".Since my 4 GB seem to be quite happy at 854MHz even though they are rated at 800, and thatwithout changing any voltages... I think I'll just stick with this setting.

850mhz for RAM rated @ 800 isn't too big of a step. I wouldn't anticipate any issues down the road running at that speed.
