Overclocking help

[TheHaydster]

My CPU won't get 4.8 GHZ, only 4.7. After 2 hours, it bluescreened, saying WHEA_UNCORRECTABLE_ERROR . Please help!

 

Specs:

CPU: i7 4790k

CPU Cooler: Cooler master Hyper 212 evo

Thermal Paste: Arctic Silver 5 High-Density

PSU: Corsair CS650M

Mobo: Asus ROG Maximus VII Hero

Case: Corsair 230t

GPU: EVGA GTX 980 ACX 2.0 SC

OS: Windows 8.1

Please, don't overclock with that cooler. Perhaps upgrading it before overclocking.

Thanks! The liars at Tom's Hardware said 4.8.

That cooler should definitely be fine for overclocking, just don't go that high if the temps are causing issues.. I have my 4690K at 4.5GHz and my friend has his FX-6200 at 4.5 both never crashing with the same CPU cooler. Just see how high your temps are; the cooler isn't causing your PC to crash, it's just overheating.

It depends on how hot his CPU was running at the time, he didn't include the temperatures that his CPU was at the time of the crash. Also, he's using an i7 where as you and your friend are using CPU's with less power so really the i7 would produce more heat. Also with the i7 having hyperthreading whereas the i5's and AMD CPU's do not, so that would draw additional heat too. 

 

It could be overheating too because he was running his i7 at higher clock speeds than you and your friend was, with a CPU that was originally meant to produce more heat.

You said just flat out to not overclock with that cooler in your original post. The cooler is fine for overclocking, he just shouldn't go that high if it's causing issues.

Evo 212 is fine for OCing, I had an FX8350 (which has a way higher TDP) running happily at 4.5Ghz with a 212 Evo.

Your limit should be based on temps, stability and nothing else, every system is different and what's right for one setup might not be for another. If you've hit the wall at 4.7 then that's fine, I mean the extra 0.1Ghz means nothing.

FTR WHEA_Uncorrectable_Error is exactly what I get with my 4770K when I try and push past 4.6Ghz so yeah, you've hit your CPUs wall I'm afraid.

Also please remove the frankly ridiculous answer you marked, its entirely wrong.
