The problem arises when the cores stay under 22-23c or so for a few minutes. After a few minutes, the whole computer just seizes up... but no BSOD or anything diagnosable. This doesn't happen as soon as I crank the heating up and the cores idle >25c or so. I'm not sure if this happens as stock speeds or not; shall I experiment?
Another observation: Increasing the PLL (1.6v to 1.8v) seems to delay the amount of time it takes before the whole thing seizes somewhat. I don't want to push much higher than 1.8v though...
So from what I gather, when your ambient temps are low your overclock freezes up and again without changing anything in the BIOS, when you increase the ambient temps the issue is no longer there?
I haven't heard of anything like that before, I really don't know what the issue might be. Have a little read on the Idle Bsod 124 / Freezing thread in my sig, it may help it may not. If all else fails, create a new thread. Sorry I can't be much help.

Try using manual voltage first, make sure you eliminate vdroop as much as possible by using the correct LLC for your system (not sure what motherboard you have). Just a note, not all SB chips will hit 5ghz, work your way up from 4.5/4.7ghz.
Added Rig...using P8Z68-V Pro
lastest test went all the way up to 0.150 offset on High LLC. Hovered fairly steadily in the 1.496 range and would periodically peak to 1.504 in CPU-Z with temps maxing at 76,83,83,78. 3 workers passed Prime95 1344 for 15minutes; worker 1 stopped after 11 minutes.
Might need to increase the vcore again but be careful when playing with those voltages, however looking at your temps I really don't think it'll be possible. As a rule of thumb, keep temps below 85c when stress testing.

As mentioned please read the first page of the thread, alternatively click on the guide in my sig.

Its a Hyper 212+ as the last screenshot said
Thanks bud, screenshot looks fine. Will add you to the spreadsheet in a moment. Thank you for contributing.

my temps are beautiful as far as i can tell.
i dont see a reason to go higher. 4.8 wont help with bf3 and 5.0 takes too much volts.
if i crossfire 5850's, will the extra 300mhz help ?
safe 24/7 vcore is 1.45v ?
Same to you, screenshot looks perfect. Will add in a moment. Thank you for your patience and welcome to the club.
Not really, 4.5ghz is probably all you need. safe vcore is what you think is safe I personally think....... well it's all in the first page, scroll down to max temps and voltages for SB.

I have a Corsair 400R, P8Z68-V/GEN3 and 2500K setup with a Hyper 212 EVO as mentioned earlier. I have quite a few fans in my case:
Front - 2 x 120MM intake fans - Default Corsair ones
Side - 2 x 140MM intake fans
Top - 2 x 140MM exhaust fans
Back - 1 x 120MM exhaust fan - Default CorsairI overclocked the 2500K to 4.5Ghz and I left the Vcore at default just so I could run a stress test, check what the load voltage was and set the offset value accordingly.
I ran Intel Burn Test on the Maximum setting and no word of a lie, within 20-25 seconds the temps on the four cores were 84-97-98-89. Needless to say I immediately
stopped the test. What could be wrong?
Is it the orientation of the fan on my 212 EVO? I'm not sure whether to have it on the right side pointing towards the front of my case or on the left, pointing towards the exhaust?
Could this be caused by too much thermal paste? I think I applied a little too much (There was thermal paste sort of coming out of the side of the heatsink and onto the metal 'enclosure' if you will (The metal catch thing that closes when you put down the arm of the CPU socket to lock the processor into place)
If this is the case, how do I clean the thermal paste off? I have some 70% isopropyl wipes; would these be OK? Perhaps I didn't tighten the heatsink enough? (How much is too tight/loose?)
I'm basically trying to establish whether it's the BIOS settings for my overclock, the thermal paste/heatsink or the airflow. I'm idling at anywhere between 29-34 degrees Celcius.
Sorry for the wall of text but the temperature are rather alarming.
Please read the guide in my sig and follow that. SB overclocking is pretty simple.
In regards to your questions:
The temps are certainly very high, the orientation and instructions should be available in the manual of some kind, you sort of want to set it up like THIS
Definitely sounds like you put tooooo much TIM (thermal paste). a small uncoocked grain of rice in the middle of the cpu is all you need, then allow the pressure of the heatsink to do all the spreading on it's own while you tighten it, on that note, you will know how much to tighten.
I usually clean it off using Isopropanol (Isopropyl Alcohol 99%, however I'm sure the wipes will do.
