The answer is nobody knows yet. If you want opinions I would say 75-77c max unless you're doing AVX Linpack SP1 which I let go up to 80c as it's an excellent stress test, far better than prime blend 12+ hours. But again this is coming from someone that would have no regrets if his chip degrades.

I would +Rep if you posted a SS of at least 50 runs of SP1 LinX on max tongue.gif.

50 runs

-1c ambient

No need to + rep me this run is from last week when I was finalizing my OC

Keep it below 85C

OR

Keep it below 80C

OR

Keep it below 70-75C

Just want to know your view on what's safe. For myself I haven't really decided on what's safe or not (rarely will hit those kind of temps for 24/7 usage).

Just include in your post what your Vcore/VCCIO/PLL/Multiplier/LLC is, load temperature, cooler and if you have enabled internal PLL overvoltage AND if you had any success with it in terms of temperatures and stability. Please only use prime95 blend for this.

Need to set some things straight because it could change people minds on running their sandy bridge from 4.5GHz to 4.8GHz! For example

What I was running yesterday:

Prime95 Blend (1 hour)
4.8GHz
Vcore - 1.40V (LLC Ultra High)
VCCIO - 1.050V
PLL - 1.80V
78C (max temp)
Internal PLL Overvoltage - Disabled (Haven't tried enabling it yet)
Prolimatech Shadow Mega

Am I safe with this? No idea, currently running it at 4.6GHz at 1.35V for now until I get some solid answers

Post post post!
your LLC is it levl 2 ?

and what is u r volatge at load in cpu z at 4.8 ghz ..
thanks
