Ok I got a question to the club. First let me start off by saying the my GTX 680 has great temps and runs awesome at stock. HOWEVER....
I originally got an OC - Power Boost +125% Clock +140 Memory +400 and was able to get through a 3DMark11 bench.
Now for the life of me I cannot even replicate that OC anymore. Drivers fail and in Heaven benchmark 3D11 Windows App error. I'm first going to assume it's me doing something wrong because I see so many other members who are getting crazy higher results. Only other possibility is I did not get lucky with my GPU and it's just a lousy over clocker. The highest OC I can obtain is 100 Mhz on the core and 100 Mhz Memory.
I down to running the fan maxed at 85% during my benching because my aggressive fan curve might not be working. I've tried both scenarios.
Case has great ventilation with fans positioned optimized.
I've restarted the system now every time the drivers failed to reset.
Anyone have any suggestions? I've gone through the Nvidia Control Panel settings and have read every setting and chose the best option for performance. Anyone else going through this or perhaps know what might be my issue?
Call me jealous but I'd love to run my card as fast as most are in the club too. My GTX 580 ran 900 Mhz at stock voltage 24/7 for a year with no problem.
3DMark11 9521 I got this new score with +100 Mhz Core and +200 Memory.Validation
I can't go any higher than this without driver failure.
Now maybe I'm just reading it wrong because GPU Boost is working behind the scenes and I just don't know it. Example is when I run EVGA OC Scanner X 2.0.0 and see the following log text:

Is the card actually being boosted to 1411 Mhz Core clock?
I guess the new GPU Boost is messing me up because I'm only at +100 Core and see others sliding it higher %. Me feel dumb.
Last question is I have GPU Boost at +132 but my voltage has stayed stock default for me at 0.987V. I know the limit according to Jacob is at 1.175V. How do I force voltage so I can get a higher OC.
