You can probably thank VDroop. I don't have a I7 but when I set my mb to give 1.27 volts to keep it stable at 3.8 it would give it about 1.23 at idle and sometimes drop below 1.2 at load which caused it to not be stable under Prime or OSST. If you have load line calibration or something similar on your board you could enable it. I enabled it on my mb and it made it run stable. Now with the mb set to give the cpu 1.2564 volts it gives it about 1.23 at idle and 1.21 at load.

Again I don't have an I7 but maybe the VDroop problem is similar.

Ok so I can't seem to get 4gz with (200x20 & 1.4vcore) but I'm 100% stable at 3,990MHz (190x19 /w Turbo & 1.375vcore). So weird...

Magus I see your board does have LLC (Load Line Calibration) try turning that on and see if it helps.

Yeah have it enabled. Also disabled all the power saving options.

Wow that still is a nice speed. Just curious can you run SuperPi 1M and see how much better it is than my Q9550 @3.8?
I got 12.230, I am betting you get about 10 or even below.

10.4s

Thanks!

SOB! My RAM is rated at 1333Mhz with 7,7,7,16. I can probably do better... thought I was limited to 1066Mhz. ><

So what did you do Magus?

07-29-09, 08:04 PM

Haven't tried yet, Im too tired from work to bother. Will work on it tomorrow night.
