So I just add the ATI Flash and BIOS's their right? Do i have to rename any files or can i keep them the way they are?

you can rename the bios anything you can remember. I usually name it 2900xt.

I give up, I have balls lol but not brains. I finaly managed to get in the DOS, but now every time I type atiflash -p 0 -newbios 12v.rom (and I have also tryed 12v.bin by renaming the files) -f i get command or filename not recognized. Im at a lost, sorry, I don't think I'll be doing this one unless someone makes an easy flasher ma boberr like that one guy did for the 2900pro to xt, that was so easy, you boot and then bam you chose what you want to flash and its done. Anyways sorry. :mad:

Thats because it's a .rom not a dot BIN.

Yeah I know, like I said I have tryed even renaming the .rom to .bin on all the files and not one of them work in the DOS.

Are you sure the files are on the disc?

Yes I am, When I pop the disc back in, I go to my computer open the CD Drive and see all the files there. Come on DaMulta Surely you know what I might be doing wrong. If not all hope is lost.

Oh your not on a floppy disc

aphex, follow this guy's explanation: http://nickfire.com/joomla/index.php?option=com_content&task=view&id=14&Itemid=29
it's simple and actually refers back to TPU a lot, I used it and took me all of 5 minutes to flash my Pro to XT but you can just substitute any Bios you want, doesn't have to be Pro to XT

that is for x850xt...not 2900xt

mandelore · Nov 16, 2007

right.. after a night of trying to get my compact flash card to boot to dos, I succeeded, and flashed my 1gb 2900xt

as you can see, 3d mode voltage is now 1.3vots!!! yippee! lol...

have to go to work in 20 mins, but will try to see what i can get out of the core and post a gpuz validation screen, but my cards alive and healthy

OrbitzXT · Nov 16, 2007

I don't mean to hijack the thread but I'm curious about something. JC, I see in your signature your scores are 3dMark05 20004 3dMark06 12008. Everytime I've seen someone's scores I either score higher in both or lower in both. But my scores are 18,604 in 3dMark05, yet 13,489 in 3dMark06. Is that more common than I think it is to outscore on one 3dMark bench and be outscored on another?

Edit: Just to be complete, I ran both again and copying and pasting exact scores so we can compare.

In 05...
Main Test Results
3DMark Score 18604 3DMarks
CPU Score 10851 CPUMarks

In 06...
Main Test Results
3DMark Score 13747 3DMarks
SM 2.0 Score 5674 Marks
SM 3.0 Score 5558 Marks
CPU Score 4918 Marks

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

but so far clocks can be changed!

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

Frikin sweet find, Mand!!!! Time for some good ol hex magic for Wile E.

mandelore · Nov 16, 2007

hurrah, 950 core straight away

tex fillrate jumped 1Gtex/sec (well, 700z more like lol)

What were the temps like for you? If they were good, I say shoot for the moon, and try 1GHz.

Exceededgoku · Nov 16, 2007

I'm just about to do mine, I'll try and explain what I did after I get it working

cepoi · Nov 16, 2007

anyone has a modified hd2900xt bios with higher clock...so that i can running CF with higher clock?

AphexDreamer · Nov 16, 2007

Yeah so seeing how I could not flash my card, I decided to see what it was like by changing the volts in ATI TOol first. This what I managed to do, on stock cooling.

Then I decided to do more benchmarking of other sorts and on OpenGl Fur Benchmark and right at the start of teh Fury donut my computer just turned off. So I Think I'll be holding off of the flashing until my 600 Watt PSU get here, cause my 500Watt just ain't cuttin it.

Dude can you run 3dmark06?

Exceededgoku · Nov 16, 2007

Okay my volts have been modded

, I'm going to go see what I can reach.
Btw the command for flashing is:
atiflash -p 0 <biosname>.rom -f
Hope this helps

That simply ROCKS!

Even with H2O cooling I get run-away temps (127c) at 810 or so in CCC "find max clocks". Don't think I'm a candidate for a voltage bump

those temps don't sound right bro :confused:

maybe you need to reseat your waterblock?

Exceededgoku · Nov 16, 2007

^^ woa... mine gets to 59oC when under 3dmark at 1.35v.... somethings wrong with your block or watercooling system...

JC316 · Nov 16, 2007

I don't get something here, I am changing the voltage with ATItool on mine, Riva Tuner confirmed, what would be the advantage of me flashing?
