2900 Pro Owners Thread

[roger_h99.nor]

Nah.. tried latest version (2.2.1) Rabit - no go.
RaBit doesnt recognize the bios correctly. According to mvktech.com its going to 'take a while' before a version supporting R600 is released.

Another issue: both the PRO and the XT bios (512MB) gives vddc 2.20V. Datasheet says vddc = 1.80V ?

[Standfest]

Hi guys! I've Sapphire 2900 Pro 512 MB with default 1.20V core.
The max stable core and mem clocks are only 820/927...
I've flahsed XT bios, max clocks are the same.



3DMarks:
01 @ 51457
03 @ 39969
05 @ 20023
06 @ 12097

3DMarks are little better with PRO bios (+7 marks in 3DMark 05, +24 marks ir 3DMark 06, but the same count in 3DMark03)

Here is my default bios: download

My PC: E6300 @ 3.5ghz, 2gb ram @ 1000mhz @ 4-5-4-15, OCZ 600W PSU, Windows XP Pro

I'm using 2x6pin connector with the shortage trick (created from the old psu 4pin connector, picture below)

[NickS]

Yup, sorry. Using 6+8.

Both 1.20v as well as me, all using 6+8p. Seems like a trend I see.

[CrimInalA]

Standfest is not using 8pin , he's using 6 pin with shortage trick .

[joshd]

Standfest is not using 8pin , he's using 6 pin with shortage trick .

but the card still THINKS its 8pin..

you guys think that gives you 1.2v core?

[CrimInalA]

definately not .
i just did the shortage trick , as a lot of people with 1.15V did before me .

this is the result :



.. nada . still 1.15V

Does anybody know what the vanilla stock speeds from ATI (no factory overclock or anything like that) are reported as in ATITool 0.27b2 for the HD2900XT 1GB GDDR4?

Just got my 2900 Pro 1GB GDDR4 and I would like to bump up it's speeds to stock XT speed, then work on a higher OC from there. The core speed currently reported in ATITool is 604.13MHz and the mem speed reported is 909MHz. What would they be on a stock XT?

[ruisu]

743MHz core, 1GHz mem

[Lightman]

would u please describe ur way of oc´ing both cards in cf? did u disable cf before the oc or did u just check the "use clocks for all devices" box in amd clock tool while u are in cf-mode?

i´m still having weird cf-troubles in vista ultimate x64... steam system info shows 2gpu´s when cf is disabled. when i enable cf it only shows one gpu and no crossfire. it´s the same in 3dmark06... i now have a orb entry showing only one card with a score of 11977
more than most c2d users achieve with one card clocked at 800/900.

OK! This is original list from NH:
Checklist

1. Disable CrossFire.
2. Extend desktop to the second monitor, Apply
3. Change the default monitor to the second monitor, Apply
4. Uncheck Extend desktop with the first monitor, Apply
5. Move monitor cable to second card.
6. Overclock the secondary card.
7. Reverse step 2-4, and move the cable back.
8. Overclock the primary card.
9. Re-enable CrossFire.

My version:
Checklist

1. Disable CrossFire.
2. Extend desktop to the second monitor, Apply
3. Change the default monitor to the second monitor, Apply
(Here you need to know that if you open GPU clock tool it will appear on 'second' screen you can't see. To bring window back to your visible screen Right Click on GPU Tool taskbar field and select Move, then hold Left mouse button and drag window to desired position)
6. Overclock the secondary card.
7. Change default monitor to the first monitor.
8. Overclock the primary card.
9. Re-enable CrossFire.

No swapping monitor cables, just 1 minute and done! Tested on XP x64...

Hi,

There is no difference between 6+6 or 6+8 pins on voltages or performance. No need to spend money for converter or a new psu with 8 pin cable.

I've moded my card as below:







Thanks,

I think 6 + 8pin just activates ATI Overdrive function in Control Center.

Give this man a cookie.

This is all it does.

You can OC with any other tool. You just cant' user overdrive without the 8pin.

Which doesnt really matter because rivatuner is still better imho.

[SteveLord]

I have the OCZ Powerstream.

I have a 4 to 8 pin adapter that came with the mobo. But my 2 4pin connectors are used on the mobo itself by the cpu.

Have 1 free 6pin and the molex to 6pin adapter. Is it safer to just use two 6pins plugged into it? And how should it look?

Im just nervous to do anything and fry my comp. hehe


EDIT - ITS ALL FINE NOW.

Yes we know this. But these cards are generally very consistent in terms of oc etc except when it comes to stock vdcc and we were/are trying to figure out how/why. Some even have only 1.0 (and the does seem to respond to higher voltage in general) I'd reference a few posts but it's gotten a bit long...

[SteveLord]

I got it in and working now. Only after googling and finding that 2-6pins will work as long as the 6pin on the 8pin port is covering the pins furthest from the other 6pin port.

Would be nice if that information is put out about this since its not in the documentation for the Sapphire at least. (unless I missed it on this thread somewhere)

The 550w minimum on the box isn't written in stone but you need at least 30A on the 12v rail to adequately power a 2900. My 520 is 33A and has 2 6-pin...doesn't yours? Most people don't have PSUs with a native 8-pin. It would be better if it were two native 6 pins but go ahead and try the adapter. You're not gonna fry anything it just might not work properly.

[Matkun]

I also have a Powerstream 520W, running fine on mine. Though I've had to dial down my OC on Vista a bit, since I can't seem to set the fan settings through Rivatuner like I can with ATITool. Stable at 750/999, but not at 804/999 (Rivatuner can't seem to hit 806).

Are there any OCing tools that work in Vista other then Rivatuner?

BTW, the 2 4-pin connections that make an 8-pin on the Powerstreams are the P4 and +P4 power connectors. They are meant for the motherboard, NOT for the video card. Do not attempt to plug them into the video card, since they shouldn't fit anyways and you'll end up physically damaging the plug by forcing them in, assuming the different current/voltage doesn't damage the card also.

[zillaoc]

Theres 2900Pro 1gb models back on newegg peeps.

Newegg

[Matkun]

Bleh.. yeah.. here's a shot of the log when it crashed running Fur:



Looks like it's overheating because I can't set the fan speed higher in Rivatuner.

Ya look at your voltage reg temp and your core hit 90c too. and this at only 1.1v.

Interesting. And not for another $20 more.

[Matkun]

It actually hits those temps at 770/999 too (which is what I'm currently running stable at). I think it just can't handle 800 at those temps. Does ATI Tool work in Vista 32-bit?

[Draxx]

Well just ordered a Corsair TX 750w, so that should let me overclock this bloody Powercolor!

Yeah I know. I actually found a thread somewhere else through Google about a guy saying something like "Also, turned on my comp and got no video no nothing. I think I got a DOA card! Also did anyone else notice how hard plugging in the 8pin connector from the motheboard was?"
