I still have to do some more testing to see what the max gaming stable is going to be. The memory and vrms don't really exceed the lower 30's c.
I would really careful with memory, better leave on stock volt and OC it to the max for memory. But on water cooling perhaps it's OK to set memory overvoltage like 1.7volt??

that is nice score for GPU and CPU

Mine is boosting to 1334 solidly on core and just benched stabily in valley at + 500 on memory (hynix). I do have a water block and love it. In games, my core has averaged 32 c or less at the stated clocks (pretty decently cold ambients though due to me turning heat off in my computer room). In benchmarks at 1398 core it touched 39 c when my room had really warmed up. My first full cover block, and I am seriously impressed. I don't recall ever seeing the vrms over 32 c either. I have been so satisfied with the stock bios so far that I haven't flashed to try and go for 1400 +. On stock bios, I have been able to bench at 1398. I doubt it would be game stable though as I suspect it would need more than + 100 on the core. I don't have sli now, but I would love to in future. Good luck with your over clocking.
Wow looks like your stock VBIOS is good in overclocking
I haven't tried OC to the max with stock VBIOS because power limit is still 109% at max.

I got a nice 1 month old one secondhand if the guy doesn't back out on the last moment.
Finally I can add the Lightning to my list of tested GTX780's. I've had 7 different cards from reference to DC2 to pretty much every popular non-ref like the Gaming, Gigabyte models, Palit Jetstream and so on..
So far nothing can even come close to the Gigabyte Ghz Edition in terms of overclock ability. (Yes, the Gigabyte supports 1.30v softmod) and I hope the Lightning can finally bring a challenge.
I only have one question. Do we have software voltage control up to like, 1.25-1.30v, yet or still just rbby tool..
Mycard can go up to 1.25volt with no mod, full load 1.150volt at stock and I can set slider to the max +100mv which is to be 1.25volt.

I ran a full run of Heaven successfully, so I'm thinking "Great! Let's go a little higher!". I step up to 1270mhz, still 1.212 volts...30 seconds in so far so good...then out of nowhere the display crashes, the fans spin up to max, and all the power LED's on the back of the card shut off, and the fans are stuck at max. I powered off the computer, then powered back on, and the LED's still won't come on and the fans are definitely stuck at max. I power cycled again...same thing...it appears to be dead. I swapped my other card back in and it powered up normally. I even flipped the bios switch between all 3 bios and it still wouldn't boot under any circumstances.
Sorry for your lost mate, hmm how com it happened? do you use Skyn3t VBIOS which has no boost?
