2900 Pro Owners Thread

Never heard anyone done this before. But it makes sense; clock for clock the PRO bios is slightly faster then the XT bios. (Probably due to tighter ram-timings.)

My humble guess is that most of the differences comparing thees bioses actually is differences in ram timings. But, hard to tell as we don't have any means to see the timings e.g we don't know what to look for in Hex editor

What is your voltage regulator temp? And is ati tool working fine with voltage change? Sorry for a bunch of question

It's already been posted, search a few pages back...

You can see a pic in my signature.
When I bench my PC sounds like jet-fighter

Thanks, I saw the pic (I was talking about vreg)

Have to ask you guys.

When overvolting (1.30 to 1.35) and OC this card, it seems to me that my PSU have a hard time keeping up. Experiencing random freezes an reboot, after playing (Crysis) for more than 1 hour. The card isn't running to hot either - all temps are reasonable.

Here my PSU (Enermax Liberty 620W):

Thanks Martin.
No instability with vgpu @ > 1.30?

On the 12V rails you got 17A +17A.
I got 22A + 22A. Should not be a problem then.

I was waiting for atitool beta3, hoping for proper voltage control and crossfire overclocking but now i´m really disappointed since there´s no serious improvement compared to beta 2.

I will be better off with GpuClocTool:

**CrimInalA** · 11-28-2007, 06:48 AM

Atitool WAS a great product , but since it is updated way too little it's of no use to me anymore .

beta3 is indeed a big disappointment for R600 owners

Well then who isn't it a disappointment for? Guess I"ll read the change log but I can't imagine offhand...

edit: Oh, Vista, of course. Sigh.

Nice going man still (obviously)

Monster indeed! So far you win the thread hee hee

I havent really been able to push mine too far due to heat issues. I'm gonna drag the rig out back to the frigid laundry area one of these days to give me a better idea of it's limit...

Yah...

At least it doesn't crash out in Vista now and monitoring works. Now I can see mem volts and such...

**Riverna** · 11-28-2007, 06:06 PM

Hi guys,

I have a powercolor 2900pro and the card run with 920/1000mhz. With my e6750 @ 4000mhz I have 13,7k in 3dmark 2006

Its a realy nice card but the 290w sucks a little bit

Nice! Is that with a volt mod? (BIOS) If not, you may have a real gem of a card there... either way tho, very good results.

I agree about the power, sometimes I can hear my PSU whine from the load. That doesn't make me feel all that confident.

yea, I have the same. I'd like to know about volts too

mine won't do past 850 without volts, but I've not tried fiddling with volts at all yet.

**R101** · 11-29-2007, 08:20 AM

I have been reading this thread for an hour, and still can't see a 2900PRO 512MB DDR3 bios that has been just voltmodded to ~1.25v, not turned into an XT. I have a Sapphire, if it matters at all.

Thanks for any info.

Are you asking someone to post a BIOS for you?

Yep, if someone has a link that'd be great, I'm a bit unlucky with the BIOS editing stuff.

hi,

yes it is with a volt mod bios (1.3v). My game setting is 800/900 1.1v

**CrimInalA** · 11-29-2007, 01:12 PM

mine runs at 837/999 stable .
benching goes to 857/999

that is with 1.15v core .
Didn't try higher mem .

voltmods from 1.20v and up make my temps skyrocket , and i only get a few mhz more , so i'll just leave it as it is .

@R101 : backup your own bios and modify it with the QuantumForce2900BiosEditor posted before . You can make your bios exactly as you want .

Hi,

I'm having major problems getting my Sapphire 2900 Pro 512 running on Linux, anyone else tried it? Tried Ubuntu, Fedora and openSUSE 10.3

It keeps over syncing at 75Hz instead of the max 60Hz my Dell 2405FPW can take, it does the same on XP and Vista too but I can get it working by manually setting it via CCC (XP & Vista). It does blank the screen periodically when I'm in XP & Vista though. Could that be a driver issue or a problem with the card?

Linux just won't run full stop even when I set xorg.conf up manually it still over syncs the monitor and I just can't get it working
