honestly, it looks like a driver crash: low voltage, power, core clock

Yea, I may need to revisit the bios settings I have flashed. Maybe I'll take a screen Cap of them tonight for some of you guys to review and critique. And maybe i just have a piss poor overclocking 670.

Does anyone know where to download Kepler BIOS tweaker from?

I Googled it but just a bunch of spam sites.

That's what I mean. How do I know which to click, its so full of ads I can't tell.

?

Is there somewhere here that its uploaded?

It says it downloaded but then won't open and run. ? Maybe I'm not doing something right. Says its a rar file and I don't have a program to run it? Weird.

Guy I get a Blue screen when I run natural selection 2, my boost clock is already tuned down to 1137Mhz, voltage is 1.212V. What could be causing it?

WHEA uncorrectable error and restarted my PC. 2xGTX670 SLi, i5-3570K

Hello everyone,

I am trying to get an unlocked voltage, power limit (to 1.21V) and GPU boost 2.0 bios for an asus dc2 gtx 670. Where can such a thing be found? Or is it only the 680 that is eligible for a gpu boost 2.0 mod because it is the same chip as 770 and 670 has no 700 series equivalent(in OEM it does apparantly).

hello,
I'm pretty new here wink.gif
I own GTX670 2Gb (915/1550).
Max clocks:
Boost 1150 - its also boost limit
memory 1800
voltage: 1.175

Everything above 1150mhz is unstable. When boost limit in Kepler BIOS Tweaker is set to more than 1150mz Unigine Heaven is crashing. Even increasing power limit is not helping.

Temps are pretty fine, its stock cooling but I modified fan curve in Evga precision ( always bellow 66)


p.s. sry for my English smile.gif

I was following the (quite brilliant) guide and chugging along nicely, and heaven started blacking out around the airship, accompanied by GPU usage/clock speed completely tanking, the frame appearing once or twice, than the whole thing would go on as normal with clock speeds reset to default (which I find to be really weird). At first I thought this just meant it was time to back off, but it still happened even when I reduced my clocks down to my best scoring run, making me start to think it was Heaven, and I just did an hour of BF4 on my max attempted heaven clock w/o an issue.

Gigabyte Windforce 2gb

1059 Mhz Default Boost
1149.7 MHz Kepler Boost
1502 Default Memory (haven't fiddled with this yet)
112% Power Target, maxed out (1.175) slider

Any ideas? Is this logically instability, or has anyone else seen this issue in heaven before ? The power holds fine, and the GPU Straightlines until this hiccup and stays at default until a precision reboot, but the system isn't crashing, nor the game. It's almost like the GPU resets itself. After this moment the rest runs brilliantly

Also of note: FireStrike in 3D Mark runs without a hitch; heaven seems to be the only thing with these blackouts at higher clocks so far.
