Overclocking my Q6700....???

I was just curious as to why you got a new board, was checkin to see if something was wrong. or if you just got a new one just to upgrade.

So I've been reading about how vdroop affects your OC a lot more than people think. and when your PC is under load the voltage drops.. and that is fine, but when OC'n that causing people to be unstable. I talked to more than a few guys that said after they got rid of some of there vdroop they were able to get stable at higher rates. I don't wanna mess around to much. So I slightly just did it a little bit.

Right now I'm at 3.44 GHz and in BIOS I'm at 1.45 volts. in CPU-Z that shows up at 1.416v and under load the droop makes it go to 1.392v
so when your clocking higher, that droop gives it even less power, when it needs more to reach that clocked speed. So I slightly adjusted mine. Now the same settings of 1.45 in BIOS shows up the same as 1.416 in CPU-Z but now under load the droop only drops to 1.408 Thats a pretty good difference. so that should help me. I'm going to lower my core now to the LOWEST i can and still be stable at 3.44 GHz and I think I'll just be happy there, and then occasionally go to 3.6 GHz for a bench here and there..

Well, update.. even after the droop mod, I still fail depending on the settings at 3.5 GHz. I read into the GTLREF's even more and I got the math behind it, it's whatever ur vcore is x 0.67 =what GTLREF should be set to, this is only the way my board is, not for everyone. so I figured that out, and set to what it needs to be at. and I'm passing. OCCT after about 15 minutes and the Core's are at 99.49% I get to 70c and I turn it off.. So thats lookin good.

So, I was messin around. and tried to go 3.7 GHz and It did not post. so went down to 3.66 and I'd post, but crash in OCCT.

So i added a small vcore increase cuz now I'm at 3.612 GHz, and adjusted the GTLREF once again to the new vcore X 0.67 = 99mv.
So I set them once again and loaded up. and I've been runnin Prime AND OCCT at same time for over 10 minutes now. Thats a LOAD.

Although Nes, I will say, my OC to 3.6 GHz and yours to 3.6 GHz your 4870 still scores a little higher than my 260 in Mark06.
at 3.6 GHz and GTX260 OC'd a little I scored 16,700

Here's The screeny. So ya, looks like I stumbled into (And after tons of Reading) a stable 3.6 GHz clock. :)

Not bad I guess.
