Semi-Noob here. I used to overclock P4 with FSB .. New way is semi-easier.

But so many posts about i5 3570K each one stating something different.

Some people say not to use prime95 but then i read more and it seems only asus mobos. So is my asrock z77 extreme4 safe to use prime still?

Other posts say that prime doesn't use all the processor and that its not enough or that its bad for the chip.

So ive been getting WHEA errors a lot. Ive been upping the volts and i now am error free. But my volts seem semi-high .. some people say 1.4 is deadly. others say its ok to go just under.

I am currently at 1.328 max 1.320 is what it says most of the time.

Core temp readings of 85C max but only for a second and normally its no higher than 80C

I will do IBT next, ushally higher.

I was stable but with WHEA errors which i guess really means im not stable. From what i read it means that the process had an error, was fixable by running it again, and doesnt crash prime.

Should i be ok with those temps / volts?
 
Solution
the chips will shut down at 105c but will throttle at somewhere in the 80 range i believe by default (could be wrong on that one, could be 90's) 72 is considered a pretty good temp after overclocking, rule of thumb is to keep it under 75c
Prime uses more than you will ever use in real life, and is totally acceptable for stress testing. 1.4 is pretty damn high, and temps in the 80's are uncomfortable to most people

also prime 95 is still the most commonly used cpu stress test around, so it's not bad, though it hasnt been updated for haswell yet i believe.
also what core speed are you running at with 1.328v??? most people can get to 4.7 without going over 1.3
 
if you are getting crashes in anything however, then you are not at a stable overclock

when testing with prime, do you overclock and then let it test for at least 2 hours. yes this seems like a long time but it is 100% necessary if you are overclocking this high so that you don't corrupt your data via a crash

Intel says 72c but..I think it'd be somewhat OK
I would probably reduce core voltage/OC a little bit just to run cooler and stable.
Try Hyper-Pi 32m for stability testing without overheating your chip. :)
