So after installed ML on X79 Sabertooth with 2 x GTX680 (works 100%) and
making many tests, i noticed that the GTX680 cards runs only at 75% of speed.
Scores from Cinebench and Luxmark vs. Windows scores are about 25% lower.

(Cinebench ML 35,52 vs. Win7:55)

At LuxMark i can see under Card GTX680 :

Clock 705MHz (both cards) !!!!!!!


(my score at LuxMark is about 2400)

this should be the difference!

I think, this is Driver-Internal and can not be changed from any .kext.
I have already changed or/and disabled agpm.kext too - but no change...
AGPM are working and OK. My Mac is 5.1 Pro model.

Have someone better scores or other informations about this ? or know how
to change the clock-rate to about 1050MHz from Windows ?

Hi. Asus P8Z68 Deluxe/Gen3 here with i2600K clocked to 4.3 ghz and ASUS GTX680 2048 mb card. At LuxMark scene Sala I am getting 1200 score and the clock speed shows like 705 mhz... So I have same problem here. Deleting AGPM doesn't help as well. Patching AGPM for correct device-id gives nothing.

About changing clock speed to 1050 mhz I have the only idea... to flash the card with a patched already "clocked" (in this case to its normal values) firmware.
