Did you try increasing ram voltage?

yeh i did go up a little bit but it didn't help. i wasn't overclocking the RAM though so i dont suppose it should've made any difference :/

Sometimes ram voltage will help stabilize cpu oc.. I guess not in ur case. Sorry bro that u got bad batch. But even without oc that cpu is the beast. Maybe ur mobo is bad. You said ur voltage went up a lot between small difference in oc..

its cool - still a great cpu at 4.1Ghz smile.gif was just disappointed because i screwed myself over to fork out for a big upgrade, making sure i got a good motherboard for overclocking and knowing the 2500k's have such a great reputation - then this happened. my 4.1Ghz OC seems stable at just over 1.2v, but to get 4.2Ghz to POST i think i needed somewhere around 1.36v. When you need a hell of a voltage bump just to go up by such a small amount its usually a sign you have hit your CPU's limit, or at least that's how it seems to me, might not be the case...

Sell it to someone that never plans on overclocking and get another. If it's the chip, you may have gotten the worse 2500k made.

haha...I am sure you will be fine until your next upgrade. I just understand the disappointment. If my chip would have clocked like that, on to someone else it would have gone. My thought process would be, sell it for $50 less than a new one, buy a new one, and get 400Mhz-900Mhz for my $50.

it was sorta tempting i gotta admit but i'll just stick with it. ive already come to terms with it and settled for my 4.1Ghz overclock lol... im still hopeful i can overclock it more at some point though but i wont hold my breath!

Apologies for the late reply but before you give up could you try a couple things for me.

Clear CMOS - Important step.


Only change these pages and leave everything else on default:
Pics (Click to show)
450
450


CPU Ratio - Manual - 45 (skip to 46 if 45 doesn't work)
Internal PLL Overvoltage - Disabled. (only enable it if it doesn't boot into windows)
Speedstep - Enabled
Turbo Boost - Manual
Long & short duration - 250
Core current - 250
Spread spectrum - Disabled


CPU Core voltage - Manual - 1.4v
LLC level - 2
PLL Voltage - 1.75v
VTT Voltage - 1.115 (or thereabouts)



Those are the only changes you should make after clearing CMOS. Obviously set your boot priority accordingly and the RAM to it's stock settings which includes the timings, voltage and frequency. Please report back when you have tried that and let us know the outcome of the results. Be sure to use Prime blend for stress testing purposes.

Good luck.

hey man i tried it 45/46 with those settings, and then with pll over voltage enabled. just wouldn't post any of those times frown.gif could be the motherboard but i reckon i probably just got a dud cpu...
