hmm yea that's what I was afraid of, was hoping I could at least get to the FTW version's stock level haha. It didn't happen during my full playthrough of crysis AND warhead at 850 core and 2000 memory nor during other games so I figured it still had some headroom...
From what I can see so far, I think i'll be stuck at 840 mhz and 2050 memory at 1.037 volts
Edit: If anyone feels it's some other issue and not the card's limit, please feel free to add
Oh also during OCCT the temperature gets to around 85 and there are 0 errors about 5 minutes into it before the monitor turns off. (I also hypothesize that the gpu downclocks because the FPS in OCCT goes from 300+ to 60ish when I run it again without a fresh restart of the computer. If this information clarifies some things I hope it does.
