2900 Pro Owners Thread

[003]

I am very curious to know, what is the maximum stable overclock you guys have been able to get on the 2900Pro 1GB GDDR4?

I would like to know, but with some conditions. First, using the stock 1.15v gpu voltage. Second, using the Pro bios. And by stable, I mean stable for the ATITool artifact scanner, preferably for at least 30 minutes, more is better.

You must have the timer on the artifact scanner actually reach 30, not get delta errors and restart.

[WrigleyVillain]

you've got DDR4 mate

Ah. Thanks. Knowing GDDR4 sucks less power I should have figured that out

[Draxx]

Anyone used the Crysis demo benchmark yet? It's in the Bin32 folder, there is a GPU and a CPU bench bat file.

Odd thing is at 1024 x768 its fine, but at 1280x1024 I get flashing red textures and the odd tearing on rocks.

This is at XT clocks.

Anyone else see this?

Well given the general state of AT w these cards I haven't bothered with the artifact scanner but I can try it. Other benches and gaming cause my card to
lose stability in the high 820s with stock bios, 1.15 vdcc. I'm sure it could go higher with better cooling and of course more voltage.

Not sure or don't remember what the max reported 1GB oc here is actually. It's a long thread and most have 512s. What's yours(so far)?

Just as an update, this ONLY happens in XP. Under Vista with DX10 there are no problems. So its the drivers, not the card.

Oh DX10 drops the frame rate from 39 to 29 fps

Well the best I can do at 1.15v and pro bios is 820 core and 1035 ram. The next highest increment that I am able to raise the core to is 833, and it freezes up on that.

I let the artifact scanner run for over 60 minutes at 820/1035 and there was not a single error. The next highest ram speed I can use is ~1050 and I get a few delta errors with that.

I am using a thermalright hr-03 with as5 and a panaflo ultra high speed 92mm fan, full load temp on the GPU is 63C.

Just played it @ 1680 x 1050 w/ all the eyecandy on (OS=XP). A single 2900PRO(XT) do not give acceptable framrates. Looked more like 20-30 fps to me.

Will look into the bench-files.

[roger_h99.nor]

Result of 'GPU.BAT' (1680 x 1050, singel card, XT speeds):
12 FPS

[Draxx]

Well in Vista 1280 x 1024 no AA high detail I get 25 fps at 800/900.

Again I get no graphical errors in Vista under DX10.

The red texture thing has to me an XP specific issue ???

[nickless]

Now, I am understanding, that everybody don`t know how I can do softvoltmod on 2900pro.
I am need know, how I can edit ready bios from 2900pro/xt?

For now I don't know about the pensil Vmod, You can look at this http://www.area3d.ch/forum/showthread.php?t=1608. Allso there is no propertly working bios editor for R600 cards until now and allso there is no final Ati tool working under Vista. With single word - nothing

PP. Ati cards always suffer from bad drivers!

[Draxx]

Anyone else have the red texture issue under XP with Crysis.

[NickS]

Nope.

Offtopic: I really hope w1zzard updates ATiTool. ATi always gets shafted by lack of a good overclocking program and community support, plus poorly optimized drivers.

[WrigleyVillain]

No doubt and I've owned ATi cards exclusively since the 9800 Pro. I have my eye on the 8800GT, to say the least.

[NickS]

I haven't. I firmly believe the 2900 XT has more potential. Plus, I really don't feel like selling my card for a lot less than I paid for 10FPS more.

[VoGonPT]

Well,

Mine currently looks like this:



Mem will not go up any further.

Quite happy with it. High performance increase from stock clocks.

And yes, im also not selling until I get a 30 fps increase from another.

Behave!

Guys, did anyone use rivatuner 2.06? My mobo is RMAed so I cannot test it myself

I,m with Riva 2.06 now and is's better than 2.05. Now under Vista Riva reads correctly the frequensy of GPU and RAM.

[WrigleyVillain]

Well, good, your conviction definitely gives me more hope. And I agree w your second point too, though I expect a 1GB card to retain better relative re-sale value. If only for the "novelty factor" of a card with a gig of vram.

I'm certainly not parting with it as soon as the next-gen is available, that much is for sure.

And thanks guys for the heads up re. RT 2.06

(In Vista, have not tried in XP yet)

1. I was getting obvious artifacts in the opening cutscene. They were like little white pebbles going horizontally during the dialog on the plane. Turned my clocks back to 800/950 for now.

2. I set the res to my monitor's native of 1680x1050 and then ran the "optimal" wizard, it came back and said my system should be set to high, so I left it at that.

3. The game ran decently smooth the whole way through. There were occasional slowdowns, but nothing as bad as what I get with Oblivion in XP.

4. I just ran the GPU benchmark, got about 32FPS avg, 42 max and I think 12 min (Frame 146 iirc).

DX10 may actually be viable after all. Also, this game is alot of fun. I love how destructable everything is. Seeing buildings actually get destroyed as a result of an enemy grenade....

Unrelated to this post: It looks like in XP after turning on the adaptive AA in CCC, and then turning it off, it seems to have stayed on. Have been on an Oblivion kick lately, so that's where I'm noticing it. That is to say, slanted lines like rooftops and the like don't look jagged at all.

Assume you're using all the high-res texture mods etc in Oblivion...have you monitored your vram usage? I have hit a max of 865 at 1920x1200 2x/8x. Any other game has yet to even break 600...

Notice we have similar setups; what is your ave load temp? I hover around 80. Do you have vdcc/mvdcc of 1.15/1.55 too?

[_g0]

I think my avg. load temp is around 85. VDCC 1.15v, MVDCC 1.55v, MVDDQ 1.938v

Also, is there a way to monitor vram temps? I'd really like to know if the artifacts in Crysis were due to software glitching or vram overheating. It looks like both NVIDIA and ATI folks are having this issue. By turning the detail level to low, those artifacts went away, and I was able to go back to 800/925. I'm starting to think whoever said that the ram chips aren't contacting the HSF knew wtf they were talking about.

I guess tomorrow I'll put a side intake fan right next to this card, it's just sitting here. BTW I have seen the air in the bottom of my case near the back get up around 40-45C.

This card makes me want to do something crazy, like putting a peltier on every component and then attaching them to a waterblock and using some kind of crazy refrigerant.

Oh man I really shouldn't post this late.

[Matkun]

Crysis demo ran fine on mine, though I am running at 775/999. All settings on High and Object detail on Very High (though it did get a bit choppy in some parts) No AA or AF, 1280x1024 resolution.

[VoGonPT]

I have downloaded it today and will check it later. I'll post details when I have them.

Behave!

[WrigleyVillain]

Also, is there a way to monitor vram temps?

Good question, I am using Riva Tuner for monitoring (including everest plug-ins) and vram temp appears to be one it doesn't do. It can do core temp and voltage reg temp. I'd be glad to be wrong here so if I am someone please correct me.

[roger_h99.nor]

Pretty sure there is no dedicated thermistor for the ram.
If we can find the location for the 'ambient' sensor, we can hope this is close to one of the ramchips.
