Do you or have you ever flashed your GPU Bios?

[Hor$eman]

1) Just wondering how many people do this.

2) Is there a windows based flash tool for x800xx? I know there is such a thing. I just wonder where on can get it. I've looked and looked, but no joy.

I know one can do it with a floppy, but I didn't install one in my new system.

Yes, mostly back when SLi needed identical BIOS versions. Tried a pipeline unlock once on an old ATi but it bricked the card; c'est la vie.

As for a Windows based tool, not that I know of, but why are you messing around with a floppy? Make a bootable USB stick and run it off that.

[ZOMGVTEK]

I probably did it 100+ times, its quite simple. Make a bootable usb, and your off.

[Hor$eman]

I've tried this, but the stick doesn't boot. Yes I can boot to it, but a underscore cursor just keeps flashing.

Using just about every method I can find on the net other than installing a floppy drive and transferring the files to the stick, in which case I would have the floppy drive installed...

I made the stick bootable using the HP Tool
I added the floppy files
I added windows system files from my c: drive

No joy...

You need to make sure your BIOS is configured properly to boot off a USB device. I have mine set as a USB HDD in bios, and set it as my primary boot device when i want to boot off it.

ive modded my 3870 bios and used ati winflash to flash to flash it (in windows, i know its not recommended but i have more pci-e slots and other cards)

[Hor$eman]

I'd like to save the file that's on it right now, and then mod it, then flash it back.

I have never use a VGA card without flashing it a modded bios. For guides try this link out

Well, I'm off to floppy land. Flashing isn't a problem, but getting a usb stick to boot to dos is. Maybe my mb just won't do it.

[xoqolatl]

I did it multiple times. Also edited my bioses myself.

haven't put a new bios in my video card yet. but if it's possible to undervolt the gpu like a cpu, i might want to do it.
is there any chance of undervolting a say radeon 4850 (further) in order to lower idle consumption?

[Hor$eman]

I don't know about ATI, but I would suspect you don't want to undervolt anything. Undervolting can make things hot just like overvolting can.

I've never tried flashing the BIOS of a GPU, but I've flashed my old nForce 680i's BIOS when I had it...

[Eldonko]

Yeah all these 3870 and 3850 cards with stupid locks at 860.

[Dualist]

Yeah all these 3870 and 3850 cards with stupid locks at 860.

even worse trying to overclock in crossfire :ROTF:

easier to bios flash the bloody clocks than use the crap software interface :D
