The ram is spec'd for DDR2800 @ 4-4-4-12 so with your overclock you memory might be well OC'd and 4-4-4-12 might not work. So make sure which ever divider your memory is at (and ram speed) is not too far OC'd.


With a quad dont use Orthos or Intel TAT - use Realtemp for temperatures and Prime 25.6.
Just a little update.

I've saved two OC profiles which i'm happy with:
380x9 (3.42GHz) - 1:1 DDR2-760MHz (1.4375v Vcore)
400x8 (3.21GHz) - 1:1 DDR2-800MHz (1.3875v Vcore)

Both are stable with Prime95 for at least 6 hours (haven't tested for longer as yet but no errors at all) but they both BSOD with Orthos within an hour. Should I be concerned about that? When I run Prime95, I choose the small FFTs option and both cores are definitely being stressed. Would it be wise to use a blend or large FFTs test with Prime95 to confirm stability?

I'm also going to lap my cpu next week which should shave of a few degrees off idle and load temps. I'm not particularly worried about my temps at the mo (29C idle, 60C load) but I think they are an issue when i'm trying for a 400x9 OC so it may help. Plus i'm going to replace my Zalman CNPS9500 with an Thermalright Ultra 120 Extreme + Zalman 120mm fan asap.

Thanks for all the advice so far
