denny, if you crashed after a few minutes of prime, try adjusting your MCH Core to 1.3v see if that doesn't help. Also, what is your I/O Core and I/O Ref? After about 425MHz, I have found that I need to raise my I/O Core to 1.2v.

I recommend launching ET6 when trying out OC sets, that way when you post a screenie, we can see the full range of voltages...

Just checked my BIOS to be sure about about the other settings. Aside from the voltage settings already reported everything else was set to normal. I did not see I/O ref listed. Is that the ICH IO? I will up the MCH Core and the I/O core on my next attempt. Thanks

I don't have ET6 but can dld it if needed

Well, the best I ever got out of my 780i was 4.275 @ 1.392v. However, I've still yet to get an oc on this board that can match or beat the vcore/clock i could get on the 780i (1/2 the reason i got this board). I know it's there somewhere, I just haven't found it yet. At the moment I'm having a hard time trying to find a good cpu ref. Seems no matter what I do, the best i've been able to to get is through 5 blend cycles....but it still crashes on #2 & #4 every single time. Seems regardless of my core/clock as well. I can drop that 4.32 down to 4.0 w/o changing any other settings and it will still dump the same cores.

I can't seem to get my E6600 to 3.6Ghz

...I get a BSOD on Windows startup or sometimes a few minutes into Windows at that speed.
With my previous mobo (680i), I was stable at 3.4Ghz with 1.30625v (1.288v CPU-Z) so voltage shouldn't be too much of an issue...even setting it to 1.4V yields the same result at 3.6Ghz.
These are the settings I tried for 3.6Ghz...

Any suggestions?

@ Nate911--I would raise the CpuTerm to 1.28,maybe 1.300

edit : You may not need that much MCH Core for 400FSB --try 1.24v

NoGuru · 06-18-09

nate911 bump your CPU term up to 1.25 and try.

Edit: lol denny is faster

Quick question for you all. I am currently running this board on my sig rig. As you can see I am running a GTX 295 in the first PCI-E slot and nothing in the second. I know that if this board was set on a X-fire setup both slots would revert to PCI-E 2.0 and both slots would run at 8x.

Here is the question: If I installed a Creative X-Fi Titanium Pro, which is PCI-E, would it revert my 295 to PCI-E 2.0 and run it at 8x? Or would the sound card work at all?

Thanks

NoGuru · 06-18-09

Yes the sound card will work and the 295 will stay the same X16

Tweex · 06-18-09

+rep to you sir for a speedy response.

dennyb · 06-18-09

Ok, I've been getting my nerve up to try higher clocks here lately. Mainly due to the encourgement to NoGuru, Grish, supa and others as well. So, thanks for that. Up until now,all of my attempts to overclock have been done with all case fans on low. I now have all 4 on high and am presently @ 4.2Ghz and testing in prime 95 blend. I tried 4.3Ghz but it was a no go-lasted 10 min -crashed 3 times with diff voltage settings. Dropped to 4.2 and voltages as follow--V-core=1.3625 in Bios & in CPUZ it is fluctuating betw. 1.344 and 1.328---Cpu Term =1.32v--- MCH Core=1.30v. Have been running 30 min now and temp ,which were really good the first 10 min are now in the mid to low 60's. They did jump up to 72/69/67/67 at the highest. I was getting a little nervous. I just peeked and worker # 4 threw an error. Rounding was 0.5 expected less than 0.4. Ol' Gigabyte Goodness doesn't seem to do too well @ High FSB. She's as happy as if she had her right mind @ 445 and lower . Get her up to 467 and higher and all she does is complain. What's a mother to do?

Im probly going to order this board next week.
