8800gt volt modding the bios...

[kellygtp]

Anyone have a bad experience with this yet upping it to 1.1v?

im gonna try tonight...but was a little worried about frying the card...
i don't think it would be too bad, but im just cautious since i cant afford another card right now lol

[redrumy3]

nope, works great if your card is not 1.1v by default, if your temps are fine go for it!

[kellygtp]

got temps of 38-39 idle 45-48 full load...
ill give it a shot... ;)

[redrumy3]

are you going to mod ur own bios from ur card or use a different bios?

Just go to the Exact Mode tab, and change Extra to 1.1v. That's it! Then save your new BIOS, and get nvflash going. Oh, make sure to back up your original BIOS before you flash.

Edit: No need to change anything on the VID Mode tab.

ok cool ill have to get the 4.2 version to do that...but thanks for the help greatly appreciated.

[kellygtp]

775 already? Damn, you've passed my 8800GT up at 1.0v. Nice

[henzo]

How stable are those clocks, and have you tested for stability yet? Those are nice clocks if they are gamable and stable.

Edit: I would suggest Fur Rendering (heats it up and tests for stability) and ATITool (scans for artifacts) for stability checks.
Post up some 3dMark scores whenever you get a chance, I wanna see if you can get into the 11k area with that 4400+ and that oc.

[redrumy3]

very nice your shader clock is insane im scared to go past 1900 lol

looking good right now 780/1900/1000 seems to be sweet spot for my card. i haven't tried running the memory higher than 1000 scared to raise that too, im still testing but i have folding going @ those speeds and its fine.

now for the Fur Rendering can i use any res and run it or does the res matter cause i rather run like 1024 x 768 in window mode would that work

semi-hijack sorry op!

well after about half an hour on atitool, i got quite a few artifacts...and i dont like that...so i backed it back down..

im playing around with it more now trying to find the best stable clocking
