Asus P8P67 Deluxe - Need some OC help

post #1 of 8
Thread Starter 
I know there are a ton of 'help me OC' threads, I've read a lot of them, including Clunk's excellent guide at http://www.clunk.org.uk/forums/overc...beginners.html

Unfortunately, whenever I set everything manually (following that guide) it BSODs within minutes of starting Prime95. I'm trying to at least get to 4.5GHz with a 2600k, with current settings: BCLK 100, Multi 45, memory is set to 800MHz for now, DRAM voltage is 1.5, and I've tested Vcore from 1.2 to 1.27. So far no dice.

Now the interesting thing is that with Auto Tuning, I was successfully running at 5.1GHz. But of course Vcore was up to 1.6v, BCLK was at 103, and temps were over 85C (don't recall extactly).

So, I'm trying to figure out where to go from here. Should I keep pushing Vcore? I know every chip is different, but shouldn't I be stable at 1.27? At only 4.5GHz, VCCSA shouldn't be an issue, right?

Any suggestions would be greatly appreciated.

No, only good chips can do that. Most need at least 1.32v.

Thanks Telstar. Will read through that and do some tweaks, then post back.

Then i'll read. I'm probably getting the same board, so i'm doing my homework

There's alot more to it than just vcore....

Have you enabled PLL overvoltage?
cpu current capability to 130% ?
digi+vrm to 350 ?
phase control to extreme
Duty control to extreme

Thanks guys. I read through the post linked above, which was great and gave some additional info I didn't see in Clunk's guide. And you're right Chewy, I believe part of my problems were some of the settings you mentioned.

PLL overvoltage was and is on
I don't think I currently have cpu to over 100% (I'll have to check)
I did not have VRM to 350, but have set that now
I did not have Duty and Phase control to extreme but do now

With the above changes and bumping Vcore to 4.25 and LLC to ultra high I am now running initially stable at 4.8Ghz, if a bit warm on Prime95 (up to 81C but only briefly - with a Silver Arrow, is that an acceptable temp?). I only ran it for about 20 minutes, just to test for the quick BSODs I was getting and had no problems. Now I will start bringing the Vcore down to see how low I can get it.

I've read different comments on LLC and am not sure if there is a consensus on its effects -- should I leave that on ultra high?

Thanks again for the assistance and any more suggestions that might be out there. Will post back.

It looks like I'm stable at 1.395v Vcore at 4.8Ghz. I know Prime95 will push things beyond any normal usage, but I did hit and hold 80-82C during several phases of testing. With my setup, is that reasonable? I would have thought the Silver Arrow would have kept it cooler in the mid 70s. I don't have the mesh side panel for the 600T case yet, so that's probably a factor, but just wondering...
