OK... if you're running a version of Prime95 older than 27.7 you're getting P4 FFTs. AKA, they are lengths and styles of the Prime computation that are designed to tax the older Pentium4 architectures (which was relevant with everything up until Ivy). Ivy Bridge has AVX now... and Prime95 27.7 alternates between P4 FFTs and AVX FFTs when stressing, fully utilizing your new Ivy Bridge CPU. The only thing I've found about the new Prime95 AVX FFTs is that they are FAR more vcore hungry. This in turn equates to higher temperatures. As it stands right now, there are no real applications utilizing AVX, so it seems like a silly thing to stress to. In 3 years when AVX applications are all over the place it'll be a concern, but by then most of us will be on Haswell, or whatever they plan on debuting after that.

So why run AVX then? I see no point if that's the case.

People do it because they're deathly concerned with stability. If the computer runs good for what you use it for, then it runs good.

I mean, to be argumentative, you and some others were concerned with WHEA errors. If you're computer is running stable, who cares if WHEA errors pop up in the Event Viewer? tongue.gif

I completely agree. I completely disregard WHEA errors now.

Sandy B. and later generations have the AVX instruction set. And there are real apps that use AVX, mostly in the High Performance Computing world where FFTs and Linear Algebra routines that can benefit from vectorization are used as building blocks. LINPACK is the benchmark, but the underlying BLAS routines are used in the HPC world. Same with FFTs that are the core of Prime 95.

For real-world apps: HPC as mentioned.

For those Overclocking and needing to test stability of the OC: because they do stress the CPU and require the right amount of current (with heat generated correspondingly). So there's strong (but not perfect) correlation on passing benchmarks that use them and OC stability. Even if you're not using AVX in your day-to-day computing, the fact that an OC setting has passed stress testing with AVX routines means it is likely (but not guaranteed) that it will be stable day-to-day. It's still not fool-proof of course which is why most will use a mix of stability tests. I use 20 minutes Prime 95 AVX 8K FFT + hyper-pi / super pi to test IMC + 3DMV / 3DM11 to test CPU+GPU dynamics. If it passes those, they're typically stable day-to-day for me (but not necessarily Prime 95 stable on all the FFT tests which needs 18-24 hours). YMMV.

I heard whea error is because the processor thinks it did some math wrong and it goes and re-checks its self. So lets just say you need 1.25 vcore but you only give it 1.20. So it does some math wrong all the time, well it has to re-check that math causing lower performance. So I am pretty sure whea errors do matter...

^ Yep thats why I care. Why overclock the extra 100MHz when the CPU is re-doing things it did incorrectly anyway?

Usually I only read here, but with the doubts about the WHEA Errors I need to register.
My 3770K will run Prime and LinX 4,5Ghz without any Error and 1,172V Vcore, but with WHEA Error.
To eliminate this WHEA Errors the correct VCore is 1,200V for 4,5Ghz.

If You are folding and You have WHEA Errors, then You would fold faster without this errors (so what is the point to ignore them).
For example: Running LinX with WHEA Errors generate less GFlops and running CineBench with WHEA Errors and You will see a less good result.

WHEA Errors can only be solved with increasing the VCore.
To check, if Your VCore is correct, just run Prime v27.7 Beta the Custom Test Min. FFT 36K Max FFT 36K and Run FFT´s in Place.
Running this Test for about 30 Min. and not having one WHEA Error is a good indicator for enough VCore.

I think there's some confusion here. The technique Dimaggio1103 is describing is not the typical spread it around thing that I have seen some do and is not recommended. Rather, it sounds like Dimaggio1103 is doing what's described in the Arctic Silver recommendations here:

"Tinting the Heatsink and Metal cap"

My temps aren't what I was expecting with my waterblock. Maybe I'll try that method and see if I get any improvement, too.

Why I have a hard time not disregarding WHEA errors is because I never get those errors during Prime, but the second I fire up some apps, I get like maybe 1 error a week or sometimes never, but sporadically it will show.
