Can't Overclock my GTX 780 Lightning

post #1 of 6
Thread Starter 
I'm using MSi Aferburner Beta 16 and the 331.82 Nvidia Drivers on my brand new GTX 780 Lightning. The Asics value is 65.4 % which is average i guess.

Anyhow, yesterday i ran Unigine Heaven benchmark and for every time i passed it I would increase the Core Clock by 10mhz. I ended up at 1150 Core Clock and 1502 (stock) Memory clock before Unigine Heaven crashed and I got a score of 1426 on all ultra presets.

My 3DMark Score was 9.2k or something similar with a small overclock. Anyhow, I wanted to push my Lightning to at least 1200 Core clock so i increased the voltage to +62 and powerlimit to 109%. I still couldnt get Heaven to not crash. I started using 3DMark instead then but that won't work either now, it starts up the first Demo then its crashes and says "an Unkown error occured, line 313, DirectX11 Diag call failed" or something similar.

How do I make 3DMark not crash and how can I push my Lightning further?

Any help would be much apprecieated

I have same problem right now, i can't benchmark my GTX 780 Lightning anymore, and i just don't know why, i have tried overclocking it a few times, but nothing "extreme" and now i get same error, except one time i got a HARDWARE REMOVED error, which is just the drivers crashing or something like that.
I would like to know what this could be caused by too. hopefully i haven't damaged my card in any ways.
Hope someone can help me solve this too frown.gif

Looks like it is chip limitation or in other words : you've got bad chip ... but in my opinion LIGHTNING should have good overclocking. In early Jan'2014 I will have this great card and test it.
Btw perhaps you guys may try to reinstall driver but with DDU first then install latest driver.
