Any settings I could look at increasing that might help besides vcore?
4.7ghz at 1.34v????????

That's really good man. Not every chip is golden, lol.

i found my 'wall'...turned out it was PLL overvoltage was disabled...heh.

4.8ghz managed with 1.36v after quick passes on ibt, but I need to get p95

IBT without AVX is probably the same as running WEI lol

Install SP1 and download the latest IBT from here and run it and post back a screenshot: http://gigaflopd.com/downloads/ibt/

then go onto Prime95 blend test

Yeah that's ultra low voltage dude, but start with 1 hour of Prime blend, not IBT. I've found that I can pass other things but fail Prime blend in 4 minutes. I can also pass Prime Small FFT easily, its those larger FFTs that crash quickly.

All IBT does is heat up your CPU (if you are running Win 7 with SP1 and AVX instructions) to levels you couldn't achieve even with a small fire going right inside your case. Yeah its another stability tester, but you have to sacrifice clockspeed in the end just so that your CPU isn't throttling when it runs IBT properly (not because the temps are too high). Or you have to spend more money on better cooling when it is completely unnecessary.

With Prime you have a reasonable overestimation of temps, maybe 8-10C. That makes sense. When I run games im like 10-15C below my max Prime temp.

All IBT does is make people either reduce their clockspeed when they dont need to, or buy better cooling. Sorry I'm not ranting at you I just cant stand that program, lol.

that's because you didn't use the avx linkpack. My temps after 12hours prime blend is peaked at 70c, with IBT (avx) its 12c higher which is absurd. I personally don't like IBT/LinX.
