Can you explain this modded bios thing you're talking about?

I have gigabyte 990fxa-ud3. Is there a mod for my bios?

It's a modded bios for the video card to allow it to run at a higher voltage.

It is a BIOS mod for his GPU, that allows for a voltage up to 1.212, more info can be found on this thread:

On average, people seem to get around 40-50mhz from raising their voltage.

So I did a benchmark test before I make any changes and I do not have time to start the OC process but I was curious if this is good for a score for doing nothing?

hmmm.....my 670 randomly crashes when playing black ops 2 killing the overclock.
post #1386 of 1562
Hi all. New here but was a religious reader until my Gigabyte GTX670 arrived last Friday. I've been trying to find the perfect overclock for the last few days and have finally settled on the numbers below. To be honest I am a little disappointed with the results as I am seeing so many other people get much bigger clocks than mine.

One thing I did notice is that anytime my card pushed its core clock to 1215, it would crash. This happened at +104, but at +103 it would stay constantly at 1201.9 and not crash. I'm guessing it simply can't handle another step up beyond that. The temperature never goes above 58 degrees so I know heat isn't throttling it. Power consumption is at 80.1% max. Just a shame I didn't get a better chip! BIOS and all chipset and graphics drivers are up to date. I am using the F12 firmware.

My memory clock is stable at +280 but not at +285.

Tested 10 times consecutively in Heaven, once in 3D Mark 11 and a half hour burn in test using Kombuster to make absolutely certain it is stable.

If anyone can help me improve on these do feel free to suggest it smile.gif

GPU Clock: 1083
Memory: 1642
Boost: 1162

Core Voltage: +100
Power Limit: 112%
Core Clock: +103
Memory Clock: +280

Use the unlocked bios
post #1389 of 1562
I was fortunate to be blessed with a golden card managing 1359 max boost and 1752 memory @1.162vcc pt 117% which I was over the moon with but then I stumbled along the modded bios thread. After reading I was easily tempted to find a new max with the increased vcc and pt because as some will agree that ocing can be mighty tempting. After playing I reached heaven 3 extreme setting stable of 1398 but being so close to 1400 I had to try but it was not to be as throttling became an issue at core boost 1411 and if it didn't throttle it crashed. This is where my testing stopped until I decided to finish my water loop and treat the card with a water block. After installing the block, I just had to try once more and I'm glad I did, max core of 1411 and memory 1853 running h3 extreme for over an hour on loop with no issues smile.gif.

That's a really good card you have there.
