    Woah, wait. How does an extra 55mhz core result in about 250 extra points in 3DMark11 than my card? What drivers are you using?

    Currently it doesn't seems to be affected by the application overclocking tools.
    Probably got locked somewhere inside the BIOS.

    But, with the help of svl7 from Techinferno, I'm currently running at 950MHz core VS the 500MHz stock. :)

    Ah, I'm using 304.48. Are you on Windows 7 64bit? Also, does your system use Optimus? Because it seems like in the beginning of every test I have a really low fps then it slowly creeps up. I see that between every test my GPU usage plummets to 0%. It's also quite peculiar how our combined tests yield just about the same score of around 2500. I'm going to install those drivers and see what happens.

    I'm on windows 7 64 bit, and my system also uses optimus and i think its normal that between tests the gpu usage plummets to 0% which is what it should do.

    Crap, idk what's going on. Now I can't even break P3000 anymore and I'm using the 304.79 drivers. I wonder what's wrong. I'm using the most recent version of 3DMark11 basic (the free version), if that makes a difference.

    But to solve your problem, though, I found out you have to go to the P0 state and boost the mem to +1000. Then you'll notice that you can't go past 3000mhz on the mem. I guess the boost acts as a limiter to the P5 mem state. Let me know what you're 3DMark11 score is after OC'ing the mem. :)

    But yeah can anyone help explain the massive disparity between our scores?

    You got that score without Ocing the memory ? :eek:
    Seems that its pretty useless to oc the memory, at least on GDDR5 version.
    Also 1200mhz from 835mhz on core without overvolting, this gpu is a crazy overclocker !!!!
