2900xt Bios hexing

[mandelore]

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

but so far clocks can be changed!

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?

 

[AphexDreamer]

Guess what, I'v found links to so many Bios mods that have voltage increase and cores increases beond your wildes dream. Look here http://www.xtremesystems.org/forums/showthread.php?t=160458&page=34

Scroll down some and you'll see that some people posted linkd to where you can download them, both for the pro and xt. Have fun and becareful, let me know how it goes.

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?

 

[mandelore]

you may get away with it, if it dont like it just flash back (obviosly a risk involved)

p.s what cooling u using?

 

[mandelore]

whats the best tool atm for 2900 flashing?

 

[AphexDreamer]

For the HD, just stock, for now.

hmmm, maybe not worth trying, it will probs cook your card

think you would at least need watercooling or a bad ass heatsink

 

[JC316]

Hmm, interesting. Very interesting, not sure I have the balls to try it on my pro yet, but I like the looks of this.

Don't worry, I'v got balls of steel! I'll take the case!! Lets blow this card!!

I await what happens brave soul.

 

[AphexDreamer]

OK, i'm willing to do this, but I just need to figure out how to use ATIflash lol. Once I figure out how to use it, I'll flash my card.

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 don't just leave us hanging on the edge of oblivion, what happened?

Dang man, I'v spent so much time and have wasted so many cd-r's and I can't manage to load DOS with ATI Tool to flash those increased Voltage Bios. Can anyone tell me specifcly what to download and how to do it, cause I'm really pissed at my self.

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.

 

[AphexDreamer]

Yeah, I have download some DOS 6.XX ISO, used PowerISO to open it, then I clicked the buttone that said Add files and I added the ATI Flasher and teh 4 volt things. Then when I booted off the CD and theis thing comes up with some crap saying banana. Can't do anything from their. Might I add i am useing vista if that changes anything.

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

no, can I use a USB drive? Why won't the cd work?

Yeah, you can use an USB stick, lemme find the instructions.
