Problem Description
Overclocking for a year now, this MB needs alot of patience. Managed to go to 3.6GHz, ram on stock (linked and synced have me 1:2, which is pretty good performance gain) but I used to get ramdom 0x000000124 crashes out of nowhere. Passing 40 linpack maximum with no prob, primes Blend and Gpu Caps Viewer (gpu burner, fur thingy) at the same time for 8 hours. Yesterday I was playing COD5 and after 2 hours it bsod me again, dagn I got one while writing this. I heard that when you get bsod's and restart, that means is the CPU, if you get bsod and no restart (freeze) it means is either ram or mainboard, is that true? I get both anyhow :P Also when I decrease bank timing (which is said to decrease latencies alot) memtest 2.10 doesn't report a thing in MB/s, is there a difference or memtest is correct?

This was my problem, the above settings are of a stable q6600 at 3.8 GHz and ram at 1900MHz tightened timings. Tested a week, 8 hours primed in blend and 2-3 times a day playing games. No crash whatsoever.

General guidelines:
Change the CPU and motherboard thermal pastes to ceramic, if you are clocking a lot, go liquid, especially on the motherboard. I thought I hit a wall at 3.4GHz, but that was just the Northbridge going hot.

Calculate CPU GTL refs, round them to a higher value and keep them there, on quad core system not only they mean stability but sometimes even less vcore. Keep NB gtl on auto.

More guiding here http://67.90.82.13/forums/showthread...202292&page=22 post 550 (scroll at the bottom)

I hope this helps you guys.

Just a quick question but what is that VID on that cpu?

Cibic · 12-12-08

My bad. CoreTemp reports Vid 1.2625

Cibic · 12-14-08

CPU gtl ref's should be rounded to the calculated and kept there, NB and ram gtl should be on Auto.

Not bad for an Nvidia chip-set. I got my Q6600 to 3.8Ghz with a ease. 475*8. P45 rock.

Cheers, it took me a year mate

From what I've heard on the Asus forums and from a few members here that is a outstanding oc on that chip with this board.That is some good work.I'll have to paste that on a notepad and save it for reference when I order my 9650.

Great job! and +1

Thanks Sasquatch in Space, I appreciate it. I will keep this thread updated upon change. Nice 8600 gt oc you got there.

Cibic · 12-17-08

Updated GLT Refs. Check the first post.

If you have freezing on transfering data and you have vista you might need a notch up in vdimm and relax timings abit
