Overclocking 2500k

How does this look?

Prime for 25 mins on these settings seems to be solid so far. 4th attempt. 3 BSOD's and 1 system hang pushes the vcore to 1.34 on 4.5ghz.

Edit:
1 hour and it BSOD's. Back to stock running at 4.2. I think this will have to do. I'd rather not make matters worse as i've only just got it.

Yes, it sounds like it. I suspect your temps are reaching 90 degrees +? You'll need to: A) Get better cooling, B) Decrease your overclock.

Well I've got a K2 with a TY-147 and HwMonitor is showing 65 as the highest it's gone. I wouldn't let it get to 90 in the first place if I'm honest.

So Far this failed - 4.5ghz, vCore 1.34v, LLC @ Level 2: This would start at 4.5, but drop to stock speeds/multi when running IntelBurnIn or Prime.

Currently running 4.4ghz, vCore 1.33v, LLC @ level 2: Multi seems to jump sporadically, but seems to be comfortable at 4.4 until the temp hits about 64-65. Prime is 30 mins in and seem to drop down the sped to 3.9/4ghz.

Drop it more and see if it does the same thing.
 
Yeah, it failed to boot completely when testing 4.3 @ 1.34v and Level 2 LLC.

So far, the most successful overclock I've had out of this has been at 4.2ghz with stock volts, C2/3, SpeedStep & turbo disabled.

The system completely flops over when trying to overclock the RAM using the XMP profile. I think I've reached the top with this one. 4.2 from 3.3 is good enough for me and BF3 has been a blessing to play on.

Your CPU is being limited by a setting in your bios called "Turbo Boost Power Limit" and "Core current limit". You'll need to increase them to keep the clocks @ 4.5ghz, there is no danger in increasing this as long as your voltage is below 1.5v. It's similiar to the +power % on AMD cards for overclocking.

4.2Ghz should be fine though, I need around 1.35v to get 4.5ghz stable, I never noticed any real benefit in performance even in cpu heavy games compared to 4.2ghz
 
Thanks for your guidance.

In all honesty, the increase from stock to 4.2 has had an impact already. At sub 60 deg, I cannot complain. I may consider playing around with it more before I upgrade, but I'm happy with the current outcome.
 
now you need to convert you fixed voltage over to offset voltage and turn on all the power saving:D;)

and see how cool it runs at idle

I don't think I have change the voltage, it's running stock.

I had thought about re-enabling the power saving, but not sure on it's impact. I will have a play over the weekend as I cannot get into the BIOS using my Logitech G510. Will have to source my other KB.

OK, so I though I would give it a try anyway as I'm inpatient. Assuming I simply enable what I disabled, that consisted of C3, C6 & Power Saving Mode.

On rebooting, I got 'Machine Check Error'.

This obviously has some correlation to what I enabled, but not sure what.

Advise?
 
not sure on asrock,but if you clocked with cpu offset and used the power states it would throttle at idle

you might need a touch more voltage then your using atm but the gains would be lower idle volts/temps

importand stock default cpu voltage + llc level + whatever offset you set = total load cpu voltage so be carefull what llc level you use and only use small offset amounts so not to overvolt the cpu so maybe high llc and +0.020v offset
