Anyone Flash their 6800GT with a 6800Ultra Bios?

Which card do you have, and which bios did you use? What was the overclock before the flash, and the overclock afterwards?


Thanks.
 
i asked this too, but everyone replied with "dont do it, its too expensive" blah blah blah

im interested tho, even tho i have an x800 xt right now.

i wonder if i'll realize any gains from flashin mine to PE cuz it does PE speeds
 
Well try flashing and tell me how it goes? I am curious but i am not putting my 6800GT at risk just for a little more performance. You can alwasy flash back so just have the orgianil bios backed up. Dont complain if you hve prbolems in the future. Nothing is guarrenteed with electronics so its all a risk.
 
I've flashed my PNY 6800GT -> PNY 6800Ultra. All it did was show up as an Ultra card in Windows (had to reinstall drivers) and run more hot (ultra seems to have higher voltages)

Before flashing, though, I edited the ultra bios to match GT clockspeeds, I didn't want to overclock yet and I wasn't sure if my card could even handle ultra clockspeeds.

To sum it up, I don't recommend it, unless you want to try to raise your vGPU and try to overclock more than is possible with stock voltages.

agreed on that^

what you did was risky and pointless because you didnt even try to find the limits of it with the stock bios, which is what people generally do first before flashing...when they hit a ceiling with stock voltage and cooling then they wana flash to get the extra voltage to see if it hits a higher peak
 
Thugs is correct. At the same clockspeed an Ultra is actually slower than a GT, as the Ultra bios has looser timings than the GT bios. The advantages of the Ultra bios is its +.1 voltage increase for greater core speeds and looser memory timings for higher memory speeds.

This being said, I still wouldnt reccommend anyone actually doing it.
