Found this thread on nordichardware.com, looks promising! im keeping tuned and hoping the voltage adjustments work!!

but so far clocks can be changed! :rockout:

http://www.nordichardware.com/forum/viewtopic.php?topic=9394&forum=45

maybe before long we will be able to voltmod our 1gb 2900's, wewt!

edit: i just had a thought...on the foxconn or wotever modded bioses for the 512Mb version of the 2900 with insane core speeds (obviously with voltage enhancements) we could modify these bios's to support the 1gb memory of the 1gb 2900 and then flash that... maybe it would work.


or, search for differences and take out the string for controlling 3d voltages and transfer that to the 1gb stock bios

Far beyond my feeble understanding... but cool.

I know people like this though, people that can see hex in real-time. It's insanity. I used to know a guy who would custom code things on the old-school goldfingers for the PS1. Ah, the glory days of console modding. I still have mine, mod-chipped, could play .iso's

I don't know if I would want to risk something that is equivalent to half my rent though. I just don't have it in me.

Man, thats cool. If anyone manages to succesfully do this let me know, I'd really like to try this my self. Will it work with the 2900 Pro or Pro flashed to an xt as well?

volt modded 1gb 2900xt file

the default voltage for core is 1.15V, this has 4 bioses, 1.2 / 1.25 / 1.3 / 1.35 core

gonna flash the lowest first, then work my way up till i hit the oc wall offered by the voltage

since i dont break 52C under heavy load im so damn excited right now

Can I use that with my Pro flash to an XT or should I not. Also this should allow for a higher overclock as well right?

righto.. here I go, turning off to flash my card, actually gonna go with the 1.3V core voltage for now, at least it only effects 3d voltage, so I have no worries of frying anything... just yet

Well, you have to make a DOS boot disc, then you add the bios and ATIflash to the disc, then you change the first boot device to CD (If it's not already there). Then once you get to DOS, you type:

atiflash -p 0 -newbios yourbios.bin -f

And that will do it.

It wont, you are working from DOS. Do you have a floppy drive? It makes things alot easier.
