Hope you have more luck with your second RMA, bud !

Does the 680 display if you put it in another PCIE slot ? The problem persisting when the 560 could have something to do with that. Try some different PCIE cables if possible, flip the BIOS onto the second BIOS on the Lightning too if...

Quote:Originally Posted by gpvecchi So, 770 bios works on 680 Lightning? Do you still have full control of all voltages, and power limit to 300%? Thank you! It works fine. Core Voltage can be adjusted, Memory & Aux voltage have been...

So after some Valley testing, both cards are stable with +100mv, power limit of 132, core clock of 1200 and memory at 7088. Lack of voltage to both memory and GPU is hurting the max OC I think. FPS is exactly the same as my LN2 Bios'd...

Quote:Originally Posted by lacrossewacker can you get any higher OC's?   Other than the BIOS difference, I'd assume there are other inherent slight differences in the 770 just from have such a mature development life time.  The...

Flashed it on my cards, runs stable, with afterburner reporting I can change the core voltage (not the mem/aux however). Don't have my multimeter to check the voltage however. Lightning clocks vs this 770 BIOS has the 770 about 5% faster...

So curiosity got the best of me and I flashed my 2 cards with that '770' BIOS. Works fine ! Cards run cooler than my LN2 bios cards did, presuming that's from the less voltage being out through the chip. Performance is about 5% more...
