2900 Pro Owners Thread

[Ati007]

Looks great
Do you know whats the difference your block and EK-FCR600 CF Xtreme - Acetal?
And what about the temps? Load,idle?
THX

[Lightman]

ok got two 2900pro with 512mb because there are 10day wait for 1gb editon her hehe.

You will be fine with them !

Flash to XT for better CrossFire and you're sorted for some time!

Xtreme has watercooling on backsite!

Idle @ 2D (300/300 @ 0.90v) = 26°C
Load @ 3D (900/850 @ 1.20v) = 37°C

chri$ch you could take your memory way higher than that, why don't you shove it at 999?

and what case do you have.. cuz i see your mobo is upside down?

[Chri$ch]

atitool artefact scan shows over 875Mhz failures...

Its an Lian Li PC-101B....

[joshd]

is clocking these the same as any other GPU, right? just spam the clocks up untill ati tool arties? any quirks I should know about before mine arrives?

hehe going first try just overclock then

does atitools or rivatuner support then?

[Kashelz]

Hmm, what sould I do? Shoud I take it or stay with my curent 8800GTS 320Mb? I already tested one 2900Pro card and it scored me 14870 points on 3DMark06 @ 887/2034

Maybe wait for next gen ATI chips that will be released soon?

apparently the 2950's are released in one month

[WrigleyVillain]

hmm

with a screen like that, high AA and AF might want 1GB maybe...

not certain though, anyone else?

Agreed. Even if somewhat overkill now for most games. At this price and overclockability too I went for the 1GB.

[nickless]

Will be there any benefit if I flash my Pro 1GB with XT bios, provided I've allready reached OC of 911 / 2466.

[roger_h99.nor]

Did a 3Dmark06 run with both bioses. Difference (in favor of the PRO) was less than 1%.

Looks like the xtbios upped the VDDC to 2.20V. It's the only difference I've seen so far.

A 512 or 1GB? If a 1GB you're the first to confirm here that they've flashed one, as far as I can tell.

Does anyone have any explanation as to why some 1GBs have VDDC of 1.15 and some 1.2?

[roger_h99.nor]

Sapphire, 512MB.

[T2k]

Just ordered the Sapphire 1GB from the egg myself. Can't wait for it! Recently acquired a 16:10 1920x1200 display so I went for more VRAM.

Shees, I thought these absolutely illogical beliefs have long gone...
FYI: 1920x1200x(32/8)= 9,216,000 byte / 1024 = 9MB total video memory.
Start doing crazy amount of post-processing and you might can reach a few hundred megs...

PS: only case when I can see 1GB used is some 3D or compositing software - which is irrelevant to display resolution, especially desktop 2D resolution.

[T2k]

First, you won't use higher than 4x AA in 1920 'cause it doesn't really make any apparent difference at this high resolution (assuming you are not displaying on a 10 feet projector) - rule of thumb says the lower the resolution the more AA you need.
Second no chance you'll take up 1GB - if I'm not mistaking baseline 1920x1200 8x SSAA means 72MB memory footprint; you have to combine with something else but I can't see any chance to hit 1GB with pp... you need an awful lot of textures etc to fill up that giant memory.

[T2k]

Yes. When you get the Pro, take out the XT. Install the Pro, and follow my guide to flash it to XT.

Re-insert the second XT, and enable crossfire. Should work perfect.

Why would anyone flash it when it already overclocks far above the XT, it's just beyond me... just to wreck your warranty or what?

Yes, I know I can flash it back but still makes no sense to me.

Yes I know it's overkill. At least right now. But for $337 w shipping I said screw it. Anyone who would pay for a 1GB XT is definitely too rich or too foolish (or both).

This thread shows over 512MB VRAM used in-game:

Admittedly, my own hasn't gone above 280 yet at 1920x1200, but I've only played tf2, ep2 and ut3 since the card arrived 5 days ago. Will be keeping an eye on it.

UPDATE: Just hit 521 on a 5 minute Oblivion test outdoor, everything maxed except int and ext shadows at half, no AA or Antistropic (wow looks incredible but hit the mid to low 30s in battle; continue tweaking)
UPDATE2: Hit 680.7 after 45 mins of playing w shadows further down, 2xAA Narrow-Tent/8x Antistropic
UPDATE3: 864.25 new record Oblivion. Bring on Crysis!

Guys I have a request...

Can somebody provide me with BIOS which sets vgpu to 1.2V at default? It must come from 512MB card, brand is of no matter for me!

Thanks in advance!

vGPU will not change with other Bios!

[WrigleyVillain]

Yeah apparently not and if it did, I'd flash mine. Again, some (at least some 1GBs) are stock 1.2. Not mine

Anything I can use to manually raise voltage besides ATI Tool? Used to use ATT on x800 and x1000 series.

[nosboost300]

ya.. i've found no advantage on this 2900xt bios... can someone show me where to get the pro bios.. and how to flash it back to pro?

You didn't back yours up first?

No Pro bios at techpowerup or NickS' site yet so I guess someone here is gonna have to hook you up.

Just follow the same process as you did to flash to XT, of course.
