2900 bios clock tool

[elementskater706]

apparently it doesn't work on abit boards because they're the only ones that check for bad checksums.

the modded bioses will have a different checksum to the original, so they just need to be fiddled with to make sure the checksum stays the same.

there are modded bioses which retain the checksum you just have to look hard enough to find them.

if i find them again i'll post em up

Awesome. Thanks man. I'll keep checking back and I'll search around online for some modded bios'.

 

[elementskater706]

For anyone who has this same problem, I figured out how to keep the same checksum. All I did was open up my edited bios (I set the clock speeds in the quantum force utility) in a hex editor, and changed some of the values so the checksum would match the original.

The highlighted row is the only row I changed values

Hey element skater - would you be able to customise a bios for my 256bit 2900 pro? I'm having a difficult time finding one with the correct checksum

 

[elementskater706]

I might be able to. I'm at work at the moment, so I can't work on it right now. I will be back on later. Does the 256-bit bios open up in the quantum force bios editor? If so, then I may be able to match the checksum to the original. I just thought it wasn't possible to flash the 256-bit version.

Is there a database for all these modded bios?

 

[elementskater706]

There is no database, at least that I know of. There is a database on this site with all the stock bios images for each brand of card.

I haven't heard anything like that

 

[elementskater706]

Hey Pablo, what brand of card is it? (e.g. sapphire)

 

[pablo NZ]

Sapphire 512mb 256-bit 2900 Pro.

 

[elementskater706]

What do you want the voltage and clock speeds at? Add any other info that you think is necessary. I may be able to make it tonight. Also, PM me your email address.

P.S. I'm not responsible if this bricks your card. Use it at your own risk!!!!

 

[pablo NZ]

Heh - things rarely last 24 hours in my hands before the warranty is well and truly void so no probs mate!

2d profile = 300mhz core, 300mhz mem, 0.90v vcore, default all else
3d profile = 600mhz core, 800mhz mem, 1.15v vcore, default all else
overdrive profile = no change (i don't use it)

Thanks heaps n heaps n heaps

hi there i have got a maximus extreme motherboard with 3 graphics cards slots picked up a s/hand 2900xt so put it in so it has 3 2900s in , at the moment i have flashed back to default bios , if i flash thes 2 are sapphire one is club3d so i was going to save the club 3d bios using ati flash as i already have the sapphire modded ones use the quantum force editor adjust clocks and volts , then reflash the cards would the identifier be 2 for the 3rd card eg 0 is first 1 is the second and 2 is the 3rd

p.s ran a few benchmarks and no improvement atm with current drivers over a 2 card setup


also if anybody wants to run the modded bios on a later driver than 7.11 a guy on xs reckons hes cracked it, i have installed 8.1 driver that way and it works ok but atm my cards are on stock bios

[elementskater706]

Yes, the third card would be number 2. I wasn't aware that you couldn't run these modded bio's with any version after 7.11 is that true?

 

[glenboy]

no it all boots up ok as normal but when you run 3dapps like 3d mark it only runs them at the 2d speed clocks doesn't upshift to 3d clock speeds , i'm going to flash my cards tonight i'll report back if the modded bios works with modded 8.1 driver

 

[elementskater706]

I can confirm that it doesn't work with modded bio's. I was wondering why I was having problems with my games. One thing I was doing as a temporary workaround was open atitool right before you play a game, so your card switches to the 3d clocks. But just to confirm, 7.11 and under are the only ones that work with the modded bios?

 

[glenboy]

can confirm zeneffects fix posted on xs works so modded bios is used with 8.1 driver , confirmed working by me on 2 x 2900s in crossfire at 893/980 on 1.35 volts on h2o, check zeneffects other postings in the same thread

Awesome. Thanks for the links.

 

[glenboy]

no worries mate

everybodys done some good work on here especially mandelore as i didn't have a clue how to flash the ati cards and now due to this thread i've probably flashed the 20+ times , so thanks for sharing your insights, i think the quickest drivers in 3dmarks anyway were the 7.11 hotfix crysis driver but the 8.1's are pretty close, heres my aquamark score on an e6850 at 4.11 ghz 2 sapphire 2900xts at 893 core 980 mem with 8.1 driver and ccc with modded bios using quantum editor, so zeneffects fix definitely works, weird how 1 line of text in driver makes it work or not work

 

[madmanmarz]

i made a bios with the quantum force editor, only changes were really low 2d clocks (300/400ish), and voltage set to 1.25. i restarted, and then reinstalled the 8.2 drivers and did the inf fix and restarted again. problem is that now, nothing comes up on my screen until vista loads (bios, loading screen etc.) on a side note, clocks so far are 875/899 1.25v (slightly conservative) and stable through 3dmark06, i think i'm gonna try raising the voltage because my temps are only 42 idle and just below 60c load.

also, i'm trying to find a windowed stress test that will put my card into 3d mode, so far ati tool and rthdribl don't work. i could deal with rthdribl if it didn't lock itself into 640x480 in full screen which also locks my fps around 60, so i can't figure out if my oc changes are helping or not.
thanks ahead of time.

ps this mod is awesome, i finally broke 10k in 3dmark06 with vista64.

 

[digitalhater]

yes, 0 is card one, 1 is card two. good luck mate!

just flashed my card to 930 core/1200 memory @ 1.35 volts.

can do more, but not gonna bother till i get more volts coz i wanna see at least 980 core, and hoping for 1k core

heres the success of my flash

Bro, how do you cool your card like that? My Sapphire 2900PRO in idle has 60C ...what should I do about these temps?

 

[digitalhater]

Hi all, well, over at the foxconn forums shamino has created a clock tool for editing bios's from the 2900 graphics cards.

I have also inquired about the problems getting past 1.35 volts within the bios so hopefully there will be some sort of solution, but this tool rox, allows changes to 2d/3d clocks etc..

so if you know your good at 900mhz core 3d, you can just go set it.

Respect to Shamino

Edit: TO FLASH YOUR CARD (warning, may kill your card, burn ur house down, kill endangered species etc if ur not careful, just a warning)

1) get atiflash: http://www.techpowerup.com/downloads/748/.html

2) make a bootable dos floppy disk, or usb stick:

http://www.techpowerup.com/downloads/330/HP_USB_Stick_Formatting_Tool.html (usb stick)

http://www.softpedia.com/get/System/Boot-Manager-Disk/My-BootDisk.shtml (floppy disk)

3) make a copy of your bios, duplacate for backup purposes, use this tool:

http://www.techpowerup.com/vgabios/BIOS_Saver.exe

4) once u make a boot disk/usb stick, copy atiflash and your modified bios to the disk its self.

5)restart computer, select in bios to start via usb drive, or the floppy drive and boot into the dos disk.

6)at the command prompt, type:

atiflash -p 0 -newbios xxxxbios.rom -f (with xxxxbios.rom being your new bios)

7)restart and enjoy

I'm a noob in overclocking modding flashing and all. Could you please tell me where do I find a good bios for my Sapphire 2900PRO 1GB ddram4 ? Or how should I get the best of it but yet not burn it?

Thanks m8!

[Frogger]

as far as flashing goes you can use your current bios and the
QuantumForce editor or you can use Dolf's auto iso disk to flash to an xt bios

[CrackerJack]

does this only work on the 2900 pro/xt?

^^^ that's correct
