I use ver. 27.7 because of AVX and if don't use that version, then yes it will run colder. The new AVX coding makes it run hotter.

I'm talking about 27.7. Like I said, at some points during the run temps approached IBT temps, but this was quiet infrequent and on average temps were much lower. In fact Prime temps are roughly the same temps as I get when encoding with x264.

What do you use to Encode?
I am using MeGUI and my temps at full 8 threads are 10-15'c cooler than Prime run.

Now this I agree with. There have been lots of us that have had voltage-related whea warnings despite successful long Prime95 runs. In fact if someone else on these forums hadn't spotted them on their PC I wouldn't have even checked my event viewer for them. Data corruption and crashes waiting to happen. I'd urge anyone to check their event viewer for these errors. I've seen people on here OCd high and apparently Prime95 stable on surprisingly low voltage, and while I'm not saying that's impossible, there would be a very good chance they will find these warnings too.

I am using x264 from the command line. Yes, I said during some parts of the run Prime95 temps approached IBT temps but on average were closer to x264 temps. These peaks will skew things slightly if you just check RealTemp for your max temps after your Prime run. I kept a close eye on it for much of the run and temps averaged quite close to my encoding temps (average 55-60 degrees).

PS if you are using MeGui with any intermediate AVISynth filters this will affect temps especially if you are using the single-threaded version of AVISynth. Plus a lot of AVISynth filters are 32 bit only.

Yup! Same thing for me, too! If I hadn't seen his post, I would've never known those existed.

OK guys here as promised 4.7ghz on AIR I could probably tune the volts down a little but I was checking CPU PLL more than anything.
I'll be back with 4.8ghz later

Nice, but keep watching it. It will hit in the 90s later into P95 and that's where you need to be careful.

a lot of people worry about 90+ temps, the cpu throttles at 105c
As an engineer, you set "limits" of your design WELL under the stress you will put on it.
For instance buildings are usually set for 3-5x their "nominal" stresses.

I don't think being at constant 105c will burn out your chip but I could be wrong. Luckily there is the $25 intel insurance for OCers
for $25 if you OC your chip and it dies you get a ONE TIME replacement.

Speaking of that insurance...I'm doing another P95 test on my chip to see if I get those WHEA 19 errors. If so, I need to up the voltage which will make me mad cause I'm already at 1.24v for 4.5GHz. If this is the case, I might just push the hell out of this chip and kill it and get my replacement lol
