2900 Pro Owners Thread

Is this considered good results?

Is that GPU clock @1.15V?

Very nice clocks! Looking at others card clocks we both are quite lucky to be @860MHz GPU .

And your score is far better than I can do on AMD for now, but you can compare to similarly priced 8800GTS 320 scores if you wish!

Congratz!

@ChaosMinionX Flash it to Pro and check for yourself if it's better! I'm on nVidia chipset BTW.

@Ownage Can your GPU go higher? have you tried up the voltage a bit?

I have a hard time benching higer. But my system was giving much problems when i start benching today. First i could do 740core or so, and much cpu speed problems. Now suddenly the problems are over, i can go back to 3.8ghz, and card did 833 core
847mhz corespeed couldn't run 3dmark06, the bench just crashed before the finish.

If i look at ATITOOL voltage control i see Vcpu 1.200??, do you have 1.150?

max bench so far:

[ChaosMinionX]

Actually... forgot... I already have a custom BIOS on my card. So that wont yield any better performance.

Thanks, yea the core is at 1.15volts. I tried ATI Tool and its causing system stability for me (Starcraft would randomly crash to desktop). Not like the volts thing works anyway, for me at least. I figured no need to overstress the card. I just simply let ATI Overdrive max out the card and leave it at that. Until some other tool comes out that allows better stability, I'll just leave it as is.

From what i read :
what's with all the choppyness after flash to XT ?
Does everyone get these hickups after flashing ? is it only in 3dmark ?
Plus , the card gets slower overal compared to PRO bios .
Is there still an advantage in flashing an XT bios then ? (except for using in Xfire)

It was an issue for me, but keep in mind that it might be OS related (XP x64) or some compatibility problems with my MSI board. In the end SM3.0 scores was about right on both BIOSes, but SM2.0 was like twice much choppier on XT BIOS. For example I have 1s lookup just on beginning of Firefly Forest test, after that it's smooth like a butter!
I suppose that my XT BIOS is oldest you can get and there for sure is some more recent one which will be as good as PRO in SM2.0 test.

@Ownage My ATITool reads 1.15V and so do RivaTuner! I presume you're using 1x6pin + 1x8pin PCIe Power connectors and that can be it!

[nosboost300]

my pro should be coming in tomorrow! i too bought the HIS 512 mb 2900pro... i've got vista and xp running.. so i'll show results with both. sadly i'm stuck on an fx62 though... and a mobo that has no voltage option to overclock my fx62!

[Rattle]

is it true on these cards pro and xt if you use 6+6 pin the vcore is 1.15 but if you use 6+8 its 1.2 ?

[nosboost300]

hate to ask this, but i havent found it anywhere.. but does anyone have the 2900pro bios? ... or know where i can get it.. or how to back it up.. in case i need to revert back or if i somehow fail to install my 2900xt bios

[WrigleyVillain]

You can back up the BIOS with ATI Tool in Misc under Settings though I can't personally vouch for what it spits out. The XT BIOS at techpowerup IIRC, thought linked early in this thread?

Pleased with mine so far, though still have alot of testing to do. Not flashed as yet. Some early benchmarks at their default res at 800 GPU clock. Stock 925 mem. Am I right that overclocking vram on these cards not as important as it already has such massive mem bandwidth?

anybody got an update on this... cuz imma be stuck on 2 6 pin connectors... or would the 8 pin for the cpu work... or is this a no??? cuz my mobo is stuck using a 4 pin.. so i got 8 pin kinda hanging there.. but i'm sure its not the same..

[Athens[2004]]

Just order mine Saphire hd2900 pro 512mb for 200~e [ www.plaisio.gr ]

does anyone run two of these cards crossfire i wonder how it goes couse is pretty cheap even for two cards.

[The Asgard]

How are the Powercolor 2900 Pro's clocking?

Also are all Pro 3 pipe coolers?

Pretty much get one in the UK for around £150 Inc

Very tempted to buy one but with the new cards only a month away ........

I've just bough PowerColor today, should be here by end of the week. I've paid £163 with free delivery which was cheapest I could find. Where have you seen one for £150 ?

[WrigleyVillain]

My Sapphire 1024 only has two.

[Truckchase!]

I'm sure they'll use up the remaining 2 pipe coolers on the Pro since it's clocked lower by default... from what I've seen, however, I don't think there's that big a cooling difference between the 2 and 3 pipe heatsinks.

[NickS]

Hmm, my Pro had 3.

[WrigleyVillain]

NickS sorry to hear yours died man! Getting a replacement?

Could it be possible that the GDDR4 runs that much cooler that they only used 2 pipes? Seems like a stretch but thought I'd throw it out there. Wishful thinking on my part, maybe.

[NickS]

@ Wrigley, thnx man. Replacement is on its way. My Dad felt bad for me cause it died so he bought me another one so I don't have to wait for the whole RMA process. The dead one is being sent in for a refund.

Funny thing. The same day I deemed it dead I was using my Biostar MATX motherboard and I was about to flash the BIOS. Got in the utility, pressed Y to begin. It gave me an error saying that I had flash write protect enabled, and to please reboot. So I rebooted and it never posted again . Not even after a long CMOS clear, different RAM, etc. What a good day that was.

[nosboost300]

erg.. so far i just plain couldnt boot to my flash drive even though it was clearly in my options.... gonna retry when i get home in about 45 min

Most motherboards seem to list it under Hard Drives, check there.

Im not sure about that but all you have to do is link the 2 "pins" not used while pluged in via a 2x3plug.

That is normal for some reason with 2900Cards. My real 2900XT does the same thing stock or overclocked. Its just for like the first second of the firefly test.




My question is I have a 2900XT and I was looking at getting a 2900pro and flash it to XT for crossfire. Someone else had the same question previously. But has anyone tested if this would work? And if it does how good? If im going to wait untell after Q2 before a new card worth upgrading comes out I was thinking about getting a second pro(XT) if the flash holds up good enough.

ya its there...but when i tried booting i got an error.. lemme check the flash drive again

I would also like the answer to this...
