Prime 95 "Hardware failure detected"

post #1 of 44
Thread Starter 
Not sure if this is the right section to post this, kinda new here! (Sort of new to overclocking in general, but I know the basics)

Anyway, I got my hyper 212+ in the mail the other day, put it in and decided to overclock my phenom 2 955 to 3.8ghz. I got it there running seemingly stable, 32c idle, max 50c. I ran prime 95 for 11 hours and somewhere along the line got this error:

I've been having problems with my ram (crashing programs, weird glitches etc) and I suspect it has something to do with wrong ram timings or voltage?
I have Corsair XMS3 2x2gb ram. I don't know much about ram in relation to the CPU and how it should be setup with an overclock so that's what I need help with. How should I go about addressing this overclock to make it stable? currently the timings are 8-8-8-24 and voltage 1.67.
Any help is appreciated!

Its not a fault its just instability, you just need more voltage or to back off a little.

Run a memtest if you believe that your ram is defective.

What is the rest of your hardware that you are using,cpu,MB?
and you bios setting,it makes it easier to help.

but heres a good Prime95 helper

basics are like this.

errors in small fft's are most likely cpu related
errors in large fft's are memory and NB/IMC related
if vcore is way too low it can error in large or small or crash
small fft's are these 8k,14k,20k and so on
large fft's are these 768k.986k,1024k and so on
running blend switches between small and large,so depending
on what size it fails at will determine what needs to be done
to fix it.

heres a great link on how to use prime95.

Torture test your CPU with Prime95


it looks like you failed some large and small fft's

Your OC is not stable, but a failed worker (your error) usually means you are close to stability. Bump vcore up a notch and try again.

Well if you are OCing your ram to that frequency you will have to raise your timings, that is probably the issue, also the ram voltage should be set to whatever is recommended, which in your case is 1.5v then you are going to have to raise it for your Ram OC, so the safe max is 1.65v so give that a try. Try running that at 11-11-11-30 unganged and try command rate 2t. give yourself some more ram voltage and that should fix the ram problem, which is almost guaranteed part of the problem

You are close but it needs more volts or you need to back down.

Edit: It ran 11 hours so you are very very close.

Thanks for the fast helpful responses!
I think I should bump my CPU vcore up a bit, yeah?
It's only a few notches higher than default, something like 1.405v
I'll try memtest as well

I am certain it is the ram timings, when you OC frequency of ram you have to loosen the timings, try the timings in my last post. Then if that doesn't work you may try doing vcore, but those timings are unstable just by looking at them.

what are the rated specs on your kit(speed and timings)?
