2500K+P8P67-M Pro = Impossible overclock...

post #1 of 9
Thread Starter 
Hey guys. I am shooting for 4.5ghz turbo. I have been using IBT on max, and trying to manipulate the useless offset voltage to get a consistent voltage, but I keep getting 124 code BSOD's, or IBT error. Right now according to Real temp, I am hitting about 65*C @ 1.37v @ 3gb IBT and 4.5ghz under turbo. Is this too high temps/voltage? Right now on 4 cores it is only a couple ghz away from my 1055t I built and sold this week, which is impressive....but I am not going to jeopordize (sp?) the longevity of the chip.

Any tips on OC with this mobo? I don't even have access to CPU PLL or anything....

Cooler is Hyper 212+ push pull.
P.S is it normal for Core 1 to be alot cooler than the other 3? It is in general 8-10* cooler.

doesn't 124 BSOD mean more VTT or vcore?

Thats what I have seemed to search on google and here.....1.37v core just did 5 ibt's without the BSOD, so well have to see , I am trying 1.36 now.....

I was under the impression most 2500k's will do sub 1.3v at 4.5ghz?

Well yea i have seen the majority of them doing 4.5 with 1.26-ish volts

I don't recommend you overclocking on an Asus mATX board. I used to own a P7P55-M, the mATX P55 board, and that thing overclocked to 3.4GHz on my i5 750 and it shut itself off on anything higher. I switched to an ATX board and I was happily hitting 3.8GHz.

All in all, mATX boards were not made for overclocking. I'm sure if you switch to a full ATX, you'll hit at least 4.0GHz, provided you have sufficient cooling.

No way it has full cooling, even the mosfets -Crossfire, etc. It is good enough, it is just a horrible BIOS.

I am running a D2 step chip, so is 1.37 @ 4.5 way off?

The temps reporting in BIOS are all toast vs windows programs, but my temps are similar to D1 stepping temps at lower volts, making me question if there is an error in one of the chips reading wrong...

I.E the D1's may use like 1.28 @ 4.5 but I am getting high 50's load on avg just like them, on air.

Maybe your chip is a dud?
Imo the motherboard is probably lacking a little bit.
Try updating the bios perhaps?
