it is only limited multi threaded so nope.
even my old dual xeons should destroy Haswell if they'd scale

Btw i wouldn't get too fussed over WEI, my CPU and SSD are getting 7.6 and everything else is 7.9, it's no biggie, but overclocking will raise the CPU score anyway.
I could never figure out why the max score was 7.9 either thinking.gif i think WEI is just something Microsoft put in place to help people who don't know very much about this stuff buy and sell their computers. Same thing Intel did with the star ratings a few years back.
things have changed. Input voltage in haswell is huge.

Try 1.25vcore, 1.76vrin, put some vrin LLC (highest or second highest level), set uncore to 34x, ring voltage to 1.15 and see what cpu core multiplier you can pass x264 benchmark 5.0.1 with

I put in those settings, with the exception of vrin LLC because I don't know what this is. smile.gif I'm trying to look it up now. I didn't see anything listed like that in my gigabyte BIOS, but I suspect I just missed it or it has a slightly different name. These settings did pass a basic Intel Burn Test though, temps hit 90. But, running at a little lower vcore is a plus?

Interestingly, found the LLC, set to turbo which is the second highest level. Ran IBT again,and my temps this time only peaked at 81, which is massively better. Is that normally what happens when you adjust LLC? I don't even know what that does tbh, but it seemed to greatly enhance my system stability and temperature.

It just keeps your VRIN voltage tight which lets you optimize it more and be more stable at lower vcore etc.

Intelburntest is an AVX stress test, so it will draw more power and run hotter than real workloads, that's why i suggested x264 benchmark 5.0.1 (you'll see temps much closer to the programs you are using and it also seems to be quite the pain in the rear to stabilize cpu for on Haswell, harder than IBT for me atleast)

Yarp. Unfortunately, with this new rig, I've downloaded about 100 gig worth of data in this month, which is my bandwidth cap (yes, Alaska still has those -_- ) I have 800 MB to get me through till Sunday, lol. x264 benchmark 5.0.1 will have to wait until then to get downloaded. Seeing as how I appear to be stable though and with lower temperatures, I think I'd like to shoot for 4.5 GHz now and see where that lands me.

Good luck! OCCT is a decent lightweight option (it has a version of linpack that you can disable avx on easily, but if you use that, you'll probably have to add some more volts after being "stable" there) if you want to see more real world temperatures, i think x264 is king for haswell stability testing though. It utilizes avx2, but in a real world way, and i've not seen anything be stable in x264 but unstable elsewhere on fault of the CPU

If you're adjusting vcore and core multiplier, adjust VRIN with it, vrin=vcore+0.5v seems to be a decent rule for my chip as a ballpark number. You can adjust uncore after everything worked fine for a while, biggest mistake people seem to make with haswell cpu's is assuming stuff works fine or will work and changing too many things at once
