What's the benefit of c1 states enabled but speedstep disabled ?

I think he means both disabled.

you do know that unless you have a microcode update, there is a bug in p95 28.9 that fails on specific FFTs, right? Again guys - hammering the FPU with p95 is not a test of stability, it is a test of your cooling.

Misinformation!! Firstly, there is no bug in P95 28.9, if there was then it wouldn't be Intel's job to fix it. Secondly.....

Correct, the bug was in Intel's microcode, not P95. Secondly, is was with AVX instructions (27.9), not FMA3 (28.9).

Picky, picky...
6 of 1.. half dozen of another... the point was the bios update with a corrected MC. Rather than let the guy continue to abuse his cpu with p95 stopped workers, either of you could have dropped the hint. Instead of a feeble attempt to correct my post oppar. tongue.gif

I'm trying to overclock my 6700k on an Asus z170a, nh-d14 cooler, 16gb 2133 ram.
I'm able to pass a 15 minute rog real bench stress test with 4.7@1.38V (actual vcore of 1.376V), but when I try to run x264 overnight it fails. I've tried up to 4.7@1.4V (actual 1.406).
My current mobo settings are:
47 core ratio
LLC set to level 6
CPU current capability 130%
CPU power phase Extreme
FCLK 1ghz
CPU core voltage 1.41 (able to pass 15 min stress test with 1.38)
VCCIO 1.2V (actual 1.224)
System agent 1.25V (actual 1.288)
Maybe I just have a bad chip? Are there any other motherboard settings I'm missing?

Try lowering vccio to 1.1-1.15v and vccsa to about 1.2v. You shouldn't need that much for either of those with 2133 ram. If that doesn't work you prob just need more cpu voltage. Passing overnight of x264 is a massive difference compared to passing a benchmark.

I'll try lowing those 2 voltages and passing 1.42v, which is more than I'd like but I'll see if it can pass a longer stress test. Seems like it fails after ~3 hours of x264

Quick way to tell if it's just voltage or something else would be drop to 4.6 and leave everything else the same and see if it fails at the same time or at all.
