post #3351 of 6939
My 6850 could reach 1000/1175 easy... sure it doesn't have as many shader clocks, but it's nearly silent and runs under 70C load.

I'll just go with "my 6870 is a dud". It happens :\\

Im in the same boat, one of my 6850's does 1000 on the core easy but the other only 960 is stable.I wonder would it be worth the trade my good 6850 for your bad 6870?lol

Hey guys! New here and noob in overclocking too.

My card is ASUS EAH 6850.

Got 2 questions:

1. MSI Afterburner doesn't change the Voltage. Although I enter 1200, it still runs the benchmark at 1.150 (stock). Haven't tried SmartDoctor or TriXX. And CCC doesn't allow voltage tweak as far as I know. What to do? Even tried setting UnlockVoltageControl=1 manually in MSIAfterburner.cfg.. Still no go.

2. I managed to just increase the Core Clock to 980 at stock voltage and run Kombustor for about 10 mins with no problems. Shouldn't I get white dots at such high clocks or the gpu should crash at stock voltage? (it crashes at 1000 though). Didn't touch Memory just yet. Is this normal or am I doing something wrong?

Thanks in advance!

Edit: Little update. I randomly tried 950 / 1150 at stock voltage. And no artifacts, white dots - nothing! How can it be? Temperature is at about 75 degrees. No crashes either. I am puzzled. In all reviews I see people say "we had to increase voltage to reach 950" etc etc..

Are you pressing the Apply button at bottom after changing the values?

Yes, of course I made a screenshot as proof coz it seems people think I am mad



950
1150
1.15v (although I set 1175 in Afterburner, it is still 1.15 in burn-in test)

And no crash or anything I ran 3dMark11 and got very high scores compared to non-overclocked state before..

Edit: Tried SmartDoctor. Still VCore stays at 1.15 only..
