@ Kelvinchen - 52C is Nice!

You are lucky. I'm on a reference blower EVGA 780 SC and did the rev4 skynet bios, the 1.3v AB unlock, and the LLC hack, but the only problem is that I Can't do anything over 1.212v without going past 71C (@100% fan). Plenty of case airflow / ambient room temps are 75F.

looks like 1.212v is the max (basically just the skynet bios mod and nothing more) for my reference card since the guide said anything over 70C/75C is trouble.

can anyone confirm that g-sync works fine with a flashed 780 skyn3t bios and LLC/voltage hacks?

That worked, kind of.
Although this rom has 10% min. fan speed, I get only 27%. I don't know why exactly this number. But the interesting part is that despite min. speed now is lower, fans' RPM has not changed — it is still in rage of 1200—1250.

So here's my question: does anyone get lower RPM with Rev. A1 Asus 780 DCII (80.10.37.XX.XX)?

excuse me guys newb 780 owner here. so I played around with my 780 a bit. didn't try anthing special. the maximum core clock I could get it stable at 1.2v is
1202mhz (could clock a bit higher but wouldn't pass 3dmark vantage at extreme) and the memory was stable at 7ghz didn't try pushing it more coz of my OCD (LOL). is this a decent clocking card? what is the average oc for most 780's? TIA thumb.gif
post #16646 of 24922
i have tried two 780s and they are stable for 24/7 at 1202 core with 1.200v. the only difference was in the memory, the first one was with samsung modules and they clocked stable for 24/7 at 7000, the second one was elpida and they clocked for 24/7 at 6600. Strange the card with elpida memory chips is a little faster than the one with samsung chips in benchmarks like heaven and valley. I suppose the elpida memory modules are with tighter timings than samsung modules. I think that with 1.200v almost every card should reach 1189Mhz-1202Mhz-1215Mhz

Though I'd ask here instead of starting a new thread, is a Gigabyte GeForce GTX 780 a worth while upgrade over my current 670 or would the Ti be a better upgrade?

Thanks wheee.gif

Asking due to my 670 playing up, think summer cooked it frown.gif

I can confirm from my personal experience that GV-N780OC-3GD (rev. 2.0) is with a very good cooling, i have never seen mine to go over 69 degrees (20 ambient, 1.200v core) and is deadly silent, my case 200mm fans are making more noise then this card.

thanks for the info +rep. impressed with how these cards clock. my gtx 680 almost has the same overclock so I was expecting it to be alittle lower because it has a "bigger" gpu. thanks thumb.gif

im from manila and my temps with my OC is reaching 80 degrees max. is it advisable to flash the bios to get more clocks out of it?

I don't know, it's your personal choise.
