wow, why is that? Due to being able to pump way more volts through it due to the water cooling?

there's a good 'chance' you can hit 1300mhz on water wink.gif

in simple terms, these silicon chips get 'efficient' with lower temp, hence need for voltage per clock would also be lower.

I can't get Asus GPU Tweak to save any settings. It always reverts back to stock. I even updated to skyn3t's bios for my card. Suggestions?

[EDIT] Figured it out. Went back to the latest WHQL drivers 337.88 and it works thumb.gif

Anyone else played with PX15 yet or is this still on the "stay away from" list?

Hey,

I should have mentionned. I reinstalled the nvidia driver many times using DDU. I tried 337.88 WHQL, 340.43. Same story frown.gif
I also checked for leaks, none to report.
I also tried the cards one by one (can' t remove them from the mobo since doing that means draining my loop and so on) but I disabled SLI, plugged only one monitor on and tried each cards separately.
Both still exhibit the same problems especially in 3DMark 11 and Fire Strike although one of them more than the other.

I'm guess I should drain the whole thing again and put the stock coolers back on and see whether the problem persists.
Warning: OFF TOPIC FLIGHT SIM STUFF! (Click to show)
Nice flight sim setup man, got the Warthog as well but with Saitek rudder pedals smile.gif I assume you also have TrackIR biggrin.gif Man this problem is driving me crazy. I just want to fly smile.gif Btw, in DCS A10c, sometime I can do a whole mission just fine and most of the times, it just freezes. At that point, I either have a bsod or I can alt-tab away from the game but the computer is laggy within Windows. Only thing I can do is restart.

It is always best to cross off every other possible issue before RMAing, in my opinion. The next step would be to re-install your operating system. I would do that before going through the tear down process. Like I said before, a bad block mount which is causing grounding issues would present its self much quicker than what you are experiencing. Rather strange that both are exhibiting the issues when running by them selves.

just dropped yesterday, definitely on my do not fly list.
