Some help with TDP of GTX780 SLI

post #1 of 4
Thread Starter 
I have read hundred of posts but am struggling to solve my issue. I have to reference GTX 780's in SLI in my watercooled rig. I have EVGA Precision X. I have update my vbios on both cards to be able to go to 1.212v and 115% TDP. When running it at above +300 GPU +400 Mem i have issues with benchmarks freezing (stress tests work fine). I believe the TDP is being reached. The temp is below 55 degrees on stress testing and the volts are ok as well. I am looking for a vbios to flash to my ref cards to allow me to increase my TDP. I can't find one that says its ok for reference cards. Im not too fussed about voltage past 1.212 but i suppose with my temps being ok I can probably push it further. Any help would be appreciated.

Are you hitting 115% when overclocking? Precision will show your card's power usage also.

Are you water cooling those cards?

Yeh, GPU 1 card is showing as hitting the TDP ( GPU 2 only gets to 109%). And yes, both are watercooled with EK blocks, hence the low 54 degree temps when OC'ed with Furmark on burn test smile.gif
