GTX 600 Series Unlocked Voltage Bios' downloads and tools. - Page 191

post #1901 of 7931
Does anyone have the modded bios for the 680 classified? Searched the thread but found nothing. Will be willing to upload if someone wants to mod both of mine.

So, all is good with the reference 670 bios on a stock evga card?
No major problems, etc?

Didn't work for me.

I can access the extra voltage but the power target offset has been reduced to 112%, when the standard BIOS allowed 122%.

It won't even complete Unigine Heaven at stock clocks. Just about to flash back to original BIOS.


Correction

It did work. I'm just an impatient tool, who didn't pay attention. rolleyes.gif

[edit] flashed back to original BIOS OK.

The modded reference BIOS has a higher baseline power target so the 112% is still higher than the 122% from the original BIOS. Also what is your highest overclock with the original BIOS? You'll probably only get a 30-40mhz increase w/ the vmodded BIOS, so'll you might need to reduce the offset to negative values.

is there a reference 680 bios mod that allows higher board power? +132 and still throttling in 3dmark11, peak power 135 biggrin.gif

80.04.09.00.01 (p2002-0000) is the reference bios version.

http://www.mvktech.net/components/com_joomlaboard/uploaded/files/NV_GTX680_01_test_6.zip

Thats the bios im using for both of my cards. Asus and palit reference. 71% and 76% asic quality.

I understand, but there's little point trying for an overclock if the new BIOS stopped the card from completing Unigine Heaven at stock settings.


My mistake, I didn't realise the mod BIOS bumped the frequencies - I thought it just unlocked a higher voltage.

OK, I gained an extra 35MHz on the core, and have the memory offset at +700.

Running Unigine Heaven @ 1920x1080 DX11, Normal Tess, High Shaders, 16xAF, 4xAA - my top score jumped 60 points. From 1865 to 1925

Temps have risen a little - Max temp was 47 degrees C after three runs. That's roughly 4 or 5 degrees warmer than normal.

[edit] Someone asked for the 3D Mark score, it was P9363, I haven't run it prior to the mod BIOS though, so I couldn't say if it was a decent score or not.

Looks like the EVGA classified has a custom PCB. Found something that may work for you in the MVKTech thread. Give this BIOS a shot.
