100 mhz downlock = severely reduced performance? Help!

post #1 of 16
Thread Starter 
I couldnt keep my 760 stable @ 4.0 since my chip is just waaaay too power hungry [needed 1.34v] so I downclocked to 1.29v and 3.90 ghz and I'm completely stable, but I'm getting highly reduced performance in cinebench!

I don't necessarily care about this since intel burn reports my GFlops only being .5 to .75 lower but it just seems really odd to me.

Here is a screenshot of my cinebench results, the 4.0 ghz being my previous clock.

Are you sure you are as stable as you think you are?

the only reason i see is that your chip is very unstable. How stable are you? Have you run Prime95 yet?

Hour into prime 95.. 68c max and still stable.

edit: doing blend tests, just in case it's worth mentioning

Run it for 6 hours.

Seems you really got a problem. With my old q9550 i reach 4,49@3,7GHz.
But stability issues should cause this drop? I rn several times this program with setting that are 100% not stable and had never a drop like this.
Even if your RAM isn`t stable it should drop that bad.

especially confusing since my GFlops in intel burn dropped by less than one....
