Which 680 do you have? Did you get higher over clocks with the BIOS flash?
On a side note: I see your new to OCN. Welcome aboard. smile.gif When you get the chance feel free to fill our your rig in your profile 'edit system'. It helps other OCN members help you when they know what you have.
Back to topic....I have a reference EVGA 680 and was wondering if any one has had any success with higher stable OC using the flash.

Sorry I have a GTX 670. And that is correct. My clocks are a bit higher but only by like 5MHz compared to the original BIOS. When I tried flashing back to my stock BIOS it is no longer stable at the max overclock I used to get with the original BIOS.

@General, I've only had the BIOS for a bit longer than a week.

No apologies needed.

That doesn't sound so good. I wonder if the overvoltage caused some degradation? Have you tried reinstalling 301.42 driver? Worth a shot. See if that doesn't clear up the stability issue.

Just OCed my GB Windforce GTX 670 to a stable 1372 mhz BUT got lower benchmark score than what I previously had at (1335mhz) at stock voltage.

Looks like I'll be keeping it at stock voltage.

UPDATE: Actually I realized the benchmarks I'm getting are lower than the ones I ran 3 months ago (3 fps and 100 points less). Could this be from degradation since I leave my card at the highest stable OC all the time? However I did change the 3D settings in the "Nvidia control panel" so maybe that would affect it? Anyone got any idea? I'll probably rerun the bench tomorrow.

Good job. thumb.gif This requires repeating. Hope it works for the others who've had stability issues with less over clock after the flash.

'Prefer Maximum Performance' is always on for me.

Update again: Apparently the driver settings do make a difference in heaven bench scores. Looks like my card hasn't shown any signs of degradation. I'll flash bios again and OC back to 1372mhz! biggrin.gif

Sadly, I only get 25 more mhz from the increased voltage though. I'll keep retesting to make sure if that's really the [stable] limit biggrin.gif

ok now i know how to get a stable and high boost. but the problem is that it doesn't work with 1293 Mhz... :/ i have to clock it down to around 1270 to get it stable :/ a + of 15 Mhz ...not very much for a Volt Mod thumbsdownsmileyanim.gif

Guys i need a little help here...

I recently switched motherboards and i had the moded bios working perfectly .... I did a fresh install of windows .

But whenever i run heaven i get a score of 20fps on my gtx 670 FTW usually i had 52 with this bios. The card is not downclocking and i can see the core and memory in a flat consistent line .The only weird thing is that the cards power never goes avobe 100% when usually on my last rig and the test rig was really above 100%

I have turned off vsync ... I even drained my loop and took the card out test it in another rig and was working perfectly i am lost here any help would be appreciated.

Btw its not only the score whenever i run heaven loos really bad.

wait...do i have to set the voltages manually to 1.23 V ? maybe thats a reason for the freezes and crashes at only 1293 Mhz..
post #1420 of 7931
can anyone adjust the voltage on this bios please?

You can leave the fan speed as it is as it's under water
