Serious overclocking problems

Hey all, ive been having some serious trouble trying to overclock my cpu for the first time. I have an i5 3570k with a hyper 212 evo cooling it as well as 3 case fans. I used this guide to overclock because i have an asrock motherboard: http://www.overclock.net/t/1198504/complete-overclocking-guide-sandy-bridge-ivy-bridge-asrock-edition
So I overclocked my CPU to 4.2 ghz using this guide because I did not want to increase voltage at all and people were telling me that 4.2 ghz should run fine without touching voltage at all. But during the prime95 blend test that I ran overnight With 4.2 ghz it failed in less than an hour (core #3 I think), so I said fine, maybe just not enough voltage. Set it down to 4.0 ghz, which is literally 0.1 ghz higher than what it will boost to out of the box, and the thing still failed on 2 of the 4 cores after about 2 and a half hours. I've heard that each CPU behaves differently when overclocking and with temperatures, but I must have gotten the runt of the litter if I can't even go 0.1 ghz over the stock speed while staying stable. Also, my temperatures are a little higher than most people receive with the same CPU and cooler, but they're not in the danger zone or anything, so I don't think that is a culprit, but anyway, I'm at a loss as of what to do in this situation. Someone please help me out :(

temps little higher means what EXACTLY? Evo will not support much more than 4.3 in the best of conditions. It is a good BUDGET cooler. Not an end all for OC. So don't expect to shoot the moon with that thing in the first place.

What did you change EXACTLY? Did you turn off power saving options? Hate to ask this but have seen it happen - did you turn off screen saver and power saving on your OS as it can interfere with test

What voltage is it actually running at? leaving on auto is often a recipe for disaster and fail. best to set manual to lowest stock voltage and follow guide in step by step for OC, raising if needed.

We need far more data detail than just observation to actually help
