2900 Pro Owners Thread

Nice clocks. Voltage and temps? And did you clock it yourself and then run the artifact scanner or did you get there using "find max core"?

Default voltages and 65c at load i think. I clocked it myself... never liked that auto clock function... The problem is that the vga froze on the 30th minute of the artifact scanning... maybe I need to raise the voltages a bit.. I'm planning on watercooling the vga soon to see how far I can get(and lower the noise ofcourse cuz at 100% fan it's a little too noisy)..

p.s. Where can i get an 8-pin cable ? Because the one for the motherboard doesn't fit in the video... And I'd like to take the vga to its limits and I don't think I'll be able to do that with 2 x 6-pin connectors

edit: 2nd try on 847/2036 again default voltages - ran about an hour perfect, but then i forgot i was benching and started an HD video and it bugged and artifacts on the scanner started to appear... I'm gonna try now on crysis and medal of honor airborne to see if its really stable

[WrigleyVillain]

What is your default voltage? Assuming 1.2.

I don't think the 8-pin will help you oc further. We thought for a bit it raised the vdcc but apparently not. But you can mod
your card or buy an adapter

[VoGonPT]

Waiting for my 2 8pin cables to arrive from Corsair

My 620 still didnt come with them so they are sending them to me

But as I read I will stick with ATI Tool as Overdrive does not allow more than 900 mem...

behave!

edit: oh, and if u dont want to fry your card even if it would fit the 8 pin to the motherboard is a no no...

[TsvetanVR]

My default voltages are 1.150v core 2.200v MVDDC and 2.102v MVDDQ
There's 1 problem though... the card is stable in Crysis demo (tested for two hours) but it crashes in the third game test in 3dmark06 which is right after the cpu tests..... if it was unstable shouldn't it crash in the first two tests and not in the beginning of the third ? Plus, everything is perfect when gaming....

[Draxx]

If your running Vista, try the AMD Whiteout demo.

[TsvetanVR]

Nah, I'm still on XP... a very very old one.... 1.5 year old maybe... I really need to format and install Vista soon

[WrigleyVillain]

My default voltages are 2.150v core 2.200v MVDDC and 2.102v MVDDQ

Don't you mean 1.15 core? (or maybe 1.2)

[Draxx]

I'm sure he means 1.15v

[hani]

i only have 1.00v on my gpu?

[WrigleyVillain]

i only have 1.00v on my gpu?

Yup, some do. From what I've seen in this thread most have 1.15, some 1.2 and some only 1.0. Generally people have clocked higher with 1.2 (which makes sense of course) but the core oc on these cards seems generally pretty consistent across all models/manufacturers while at the same time however the vddc is not so consistent, which is strange.

Edit: wait I just realized I meant 1.1 not 1.0. Don't think I've seen a 1.0 yet. ATI tool reports same?
Edit2: why do you have your cpu multi at 6? Disable all the power-saving features, which is probably it, at least as a test.

Oops... yeah, 1.15 core

It's 1.1 3D, 1.0 2d.. I'm one of the ones with that. Stress tests out at about 800, 780 if I don't turn the fan speed up from the default speeds that are in the BIOS.

I can have it running at 825 for short periods of time, but it hard locks after only 5-10 minutes of stress testing. Also if I turn up the VDDC to 1.15 or 1.2, it handles better, but heat generation is noticeably higher and ATI Tool doesn't set it properly. Have to re-set the VDDC manually each time I boot, which isn't worth another 25-30 Mhz overclock to me.

1.00v is the 2D voltage. If he runs 3D that will go up to 1.15 or 1.2v

[hani]

ok thanks

[MTP04]

@Solarfall, What are your card clocks? Nice 01!

[quake6]

Can you change voltage with ati tool?Is there any chance?

[Solarfall]

@Solarfall, What are your card clocks? Nice 01!

all of those 3dmark runs were done with 874/981 clocks i can run my card at even higher clock but for some reason that dice run i did i could not get the 3dmarks stable at previous clocks that worked (901/1035mhz )

[ownage]

A few days ago i visited a friend to do some crossfire damage.
We benched 2900pro in Crossfire in his rig

We could get 27772 points in 3dmark05
http://www.hardware.info/images/user...s/001930-5.jpg
e6850 @ 4546mhz
cards @ 841/952

[Jinxy]

My crossfire'd Pros @ XT scored just under 20,000 in 06

...but I'm switching back to Nvidia. I had too many problems with this card, and I'm getting really obvious artifacts in everything now, OC or not.

I'm getting an EVGA 8800GT, btw.

Thanks everyone for all the help.

It's official, the maker of this thread & this guide (I) has sold his 2900 Pro... in favor of either a 3850 Pro or an 8800GT, whatever is better.

Sigh, what a short-lived (and fairly awesome) card. It's a shame.

Well.... good decision nick... short lived, but good while it lasted...

That's too bad man. But looking forward to hearing of your experiences with the GT.
