Pretty nice score mate.
Quantumforce2900 bioseditor don´t work on 256bit card, anyone know how to editor bio´s on 256bit edition gfx?

[runmc]

Nice thread Nick

I have picked up a couple of 512 Pros from Newegg for cheap this past week. I know from reading there is a way to overclock the XT in Crossfire. It seems that the Pro bios runs smoother than flashing to the XT bios. For that reason I would rather not flash the bios.

1. Is there a way to overclock the Pros in Crossfire?
or if not
2. Is there a modded Pro bios with higher volts and clocks?

hi runmc,

first check if u got the 256bit or the 512bit mem interface version of the 2900pro. if u got the 512bit version u can use QuantumForce2900Editor.exe (just google for it, i think techpowerup has got it up) to modify the bios of ur 2900pro. u can also read thru the 40+ pages of this thread to find some modded bioses. but it´s easier to just dump the bios off one of ur cards with atiflash and then edit it with the quantumforce2900editor. just set the 3d gpu and vram clocks u want and voltage (goes up to 1.35v in bios).

Again, NICE!

Do you happen to know why it doesn't work with the 256bit version?

[Martin.v.r]

And another result with my new(old) Q6600
16 518 Mark06

[MadDias]

Do you happen to know why it doesn't work with the 256bit version?

i don´t know exactly why. but it seems to be a very different bios to the 512bit edition. the quantumforce bios editor was for 2900xt cards and a 2900pro 512bit is nothing other than a downclocked 2900xt.

[road-runner]

Hey guys I picked up a 2900 Pro and added it to the rig in my sig crossfire with the 2900xt. I ran 3DMark06 and got 19517 3DMarks http://service.futuremark.com/compare?3dm06=4959749 with both cards over clocked in CCC. The 2900xt is water cooled the pro is running stock air cooling. Question is will I benefit much by flashing the pro to an xt, and is it worth the money to get a x38 board?

[MadDias]

if u get the pro to run at xt speeds it may be even a little faster than the xt. some people even thought about flashing their XTs with a modded pro bios

[road-runner]

Are there any modded bios for a sapphire 512mb pro available for download? I do not think I want to try the hex editor, I do not trust myself...

[MadDias]

MUOB (mod ur own bios )

just dump the bios with atiflash and mod it with the editor.
ur 2900pro is a 512bit?

Yes I made sure I got the 512mb with 512mb memory not the 256, ok I see how to do it now, it helps when someone guides you to the proper tools. Thanks a lot....

[road-runner]

So which ones do I change just the ones I circled?

[s0lid]

So which ones do I change just the ones I circled?

Yea. I made one bios with XTs clocks. Works fine

[road-runner]

Flashed my 2900 xt to 930/1075 1.25 water cooled and now it is slower than it was stock. I get 12804 stock in 3DMark06 now I get 9344? Do I have to reinstall drivers or did I do something wrong?

[Rattle]

so is the general concesus that a overclocked pro bios is better than a xt bios?
I been recently hearing this mentioned here and other places.
I recently hit some hard times and sold all my high end stuff and SLI g92's and my sexy $170 512bit 2900pro will be here today.

thanks

Yes. I believe memory timings were the assumed reason the Pro bios seems faster.

[quake6]

Can you OC in crossfire with overdrive? I read something that you have to change your default position of monitor ( http://www.nordichardware.com/Guides...lse=516&page=2 ),but is that only for ati tool or I need to do that even with CCC overdrive?

don´t go over 999 on the memory... but 930 on the gpu should be alot faster than 740.
3k lower is alot. did ur cpu score also decrease or is it as high as in ur stock run?

@quake6: with the cat8.1 drivers u can oc both cards with overdrive. u can oc them individually by choosing the card u want to oc in a dropdown menu in overdrive. no need for changing primary displays when using overdrive.

YES. you will pass 20k on your first run i promise. i just did this run to see if 2900pro bios is really faster than 2900xt... and it is. worth 200pts. this is my every day running speeds though so im sure i can get higher, i could even load 7.11 *non crysis hotfix* and it would be worth another 300 points...




here is my pro bios i just made for this run. 1.2 volts so with a good fan profile in atitool or similar program it stays below or at 75 when under load.

i wonder if #2 was one of you guys?

[Rattle]

I dunno if this is mentioned somewhere in this thread already but how can I get some kind of driver options if I just use the display driver?

I am having trouble Ocing no matter what i use or do when I have CCC installed.
With just the display driver and riva tuner this 2900pro 512bit does 850/999 on 1.15v no problems. Thing is I have no driver options or menu of any kind liek this.
