2900 Pro Owners Thread

Aftermarket cooling is always better. In my opinion its worth it (if you can spare the cash ofc...), Mine went down from 60 idle and 80 full to 60 full, and 30 idle... and the silence is gold.

OC'ing is also better, not that I can reach that high now as I'm on vista and cant get the Overdrive to stop managing the oc so only on XP i use ati tool. As you know overdirve is very "soft" and only allows for 900 mem and 856 core, but I can run at that speed no problem for benching.

The plus side of HR-03/R600 is temp and silence. If you are changing only for some more mhz and the stock cooling noise at 50% (not even thinking about the 100...) is ok by you then dont.

Behave!

How higher could you clock it with the HR-03?

How higher could you clock it with the HR-03?

Basically nothing higher . just more silent and cooler temps .

to get higher speeds you need to put more vcore , which the HR-03 can handle for the core , but not for the voltage regulator chips .

I have an HR-03 on my 2900pro, and your right about the VRM getting hot, one quick little improvment is replace that crap thermal tape they have on there, I scraped it off with a razor and used the heatsink compound that came with the HR-03, put a thin layer on the sink and a thin layer on each vrm chip. This saved me 20c on VRM load temps (yes 20c). I could have probablly used AS5, the VRM's are in an acrylic housing and saved a couple of more C.

Interesting .

I'm curious to the following :
Do you have a 92mm fan attached to the heatsink ?
Do you also have a 120mm fan blowing on the card ?
Do you have heatsinks on the naked IC's next to the heatsink you were talking about (Vreg) ?

Yes 92mm Vantec.

No there is no 120mm fan blowing on card.

No but I've never checked their temperature under load, I guess I should.

Well I'm happy with my Pro, Running 0.9v in 2D, and 1.2v in 3D, 840/1000. The card runs Whiteout, Crysis DX10 artifact free at thoose speeds looping for 30 minutes, I can run 880 on the core but Whiteout artifacts as does Crysis, everything else runs good though.

Since I've got the VRM running cooler I'm going to up the voltage to 1.25v and check stabilty, hopefully I can get 870 on the core 100% stable.

Here's a 3Dmark06 score, card is running 860/1000, 13306, http://service.futuremark.com/compare?3dm06=3906507

The RAM I've run upto 1100MHz (2200MHz effective) which it runs stable, never tried higher, but the card has more then enough bandwidth at 1000MHz.

[ownage]

Finally some nice numbers on my card!
I really need better VRM cooling.

So according to this thread there is a new verison of ati tool imminent supporting voltage control for 3850/70. Guess what I'm wondering?

[Draxx]

Whats the facts about memory timings over 999Mhz? As I can run at 1033 artifact free, but if thats slower than 999Mhz I'll keep it at that!

Advise please

I would love that.... max oc finding on G92 would make me happy...

I don't *think* it makes a difference, but being that I can't get my memory that high, I haven't tested.

If you want to test, make sure to do everything to try to make it bandwidth-restricted (i.e. very high resolution, etc.) and run through some benchmarks.

[WrigleyVillain]

No of course that's awesome as well as the quick 3850/70 support; props to W1z. It's just we still don't have reliable software voltage control for R600. Hopefully that's also included in the new release...

Well I'd rather be in your position, high core and lower memory. My core won't go over 800 for Crysis etc, I have to drop it to 777 for Whiteout!

Not good

[jamend]

Has anyone tried these in crossfire? I'm scoring around 14K in 06 (835/999) so I'm thinking something's wrong... I tried running my cards as Pro/XT, XT/XT, and Pro/Pro roms and CCC doesn't complain when I enable crossfire but my performance doesn't really change.

[WrigleyVillain]

It doesn't scale in anything or just 06?

[WrigleyVillain]

I am wiping my machine soon, anyone have any comments regarding if I should run cat 7.11 or stick with 7.10 for my Pro?

[jamend]

I don't notice a change in anything.

You should stick to 7.10 (less buggy) unless you want to play Crysis (flashing objects bug).

My perf suite reported no notable performance differences. It was so boring I didn't even bother to post it.

Hi, i need to buy a 8 pin cable for activate O.C in this card, any one know one place to buy this cable, in my country Spain in don`t see any store...

Another question: what POWER SUPPLY, has both cables: 8 pin pci-x cable and 6 pin, built in..? maybe i buy a new Power Supply..

Thanks for the help..

[Draxx]

You don't need the 8 pin to overclock. Two 6 pin will be fine and just use Rivatuner to clock it

[L7R]

Thanks for the help..

Zalman 850 watt ZM-850HP has 2x8pin & 2x6pin cables. I have it an it's the most silent PSU in +700w category. Made by enhance so it's bargain for that price (I paid 160euros).

You could also try something this, I have overdrive with only a 6pin cable.

i ordered the exact same psu. got it this monday and installed it. i was surfing the web for about 2hrs and just when i was about to change my signature here my screen went black and funny noises were coming from my pc. i opened the side panel of my tower and saw the red led´s on my 2900´s flicker. that´s not a good sign, i thought and powered off the system. the system never came back to live again with the zm850-hp.
now i´m back with my old ocz700wgxs and waiting for a replacement of the dead zalman psu. hope the replacement they send me will live way longer than 2hrs.

2900GT could be flashed to XT? did sombody tried?
