[Official] MSI GTX 680 Lightning Owners Club - Page 430

post #4291 of 7827
Just successfully completed a few runs of Heaven Benchmark 3.0 with my new Lightning, at max voltage (+100 mV), +110 core, and +500 memory I'm getting ~1306 MHz core, 1712 MHz memory speeds. I tried to push it to +150 on the core, but had a driver crash, so this appears to be the best overclock I'm going to get (good enough for me). It does appear that the newer cards aren't overclocking as well as the older ones pre-Nvidia lock. Does anyone know if increasing the Aux or memory voltages would increase my overall stability, or should I just leave it at their default settings?

Yer I switched to the older gen drivers in search of my number one spot back in the 3DMark11 thread. Maybe because I overclocked my CPU to 5.2Ghz, this was the cause and further testing will confirm. I posted here hoping someone else was hgaving the same issues since switching to and from the new betas.

Maybe I have messed up but also I don't buy into this chip degredation but maybe I am wrong.

Ah, the CPU maybe? I was getting the red screen right after loading Windows, before I even had a chance to overclock my Lightnings (don't have Afterburner set to open on start-up). I've had unstable instances of overclocking my CPU before, wouldn't get into Windows. But I never had my screen go red from an unstable CPU overclock when loading Windows before I got my Lightnings. So, maybe the red screen is related to when you're using a Lightning and get a CPU instability crash? Only thing I can think of, because I got the red screen before even touching my Lightnings, and never got the red screen from a CPU overclock before getting my Lightnings.

Deffo a strange one and I will dig a little deeper. I will be putting XP on a drive to bench 3DMark06 and I will see if it is still doing it. Hopefully I have not killed one or both of my cards frown.gif

FIX: nvidia control panel set bf3 to "prefer max performance" fixes bullcrap 800mhz issue.

Had the same problem.
