2900 Pro Owners Thread

[WrigleyVillain]

According to that thread, the bios is for 512MB only. I'm about three drinks away from trying it.....

Haha

But I guess i've missed something as to why u want to try it...this is the foxconn bios right? thought helped cf...does it up voltage too?

[roger_h99.nor]

LOL @ Truckchase!

One guy over at http://www.diskusjon.no/index.php?sh...=836984&st=980
tried one of the bios (880MHz Core, 950MHz Memory, 1.25v 3D Voltage)
- it flashed OK, but 3DMark06 caused a instant freeze.

He got cold feet and flashed back to XT again

[Martin.v.r]

i used a 6.2mm x 8cm cobber tube from braketube to a car
an drill the inside up to 5mm

[Trike]

overclocking in Crossfire mode is easy for me, since I run dual mons. I have a monitor hooked up to each card. All i have to do is disable crossfire in CCC and run rivatuner. overclock both cards and re-enable crossfire. works like a charm in XP. Although vista is a whole other beast.

What games are people playing with crossfire? been alittle dissapointed with the amount of crossfire compatible games.

[Trike]

I'm still waiting for dtek's uni-sink for the 2900xt, before I watercool the cards. Really anxious to get them in the loop.

Yah, to 1.25v, and I suspect it may up the vDDR as well, since they set the default clocks pretty agressive. (for us "old" xt owners with the crappier ram) ATI Tool doesn't work for me so I'd like something that will give me a vGPU bump.

Too bad I quit drinking too early last night...

[Draxx]

Is there a "best" XT BIOS to flash to? i.e. is the HIS better than the Sapphire or is the Powercolor better?

[WrigleyVillain]

Seems to be no, but that's a good question that I don't think we ever got a definitive answer to, in this thread anyway.

[Truckchase!]

I did it (flashed the BIOS) because Crysis is coming out next week and based off the beta I need all the FPS I can get. Here are the preliminary results:

2d GPU Voltage from 1.00 to 1.10 and amperage from 25.3 to 33.1. Not sure why they raised 2d volts, that seems dumb. Maybe there's some sort of global multiplier that affects 2d as well. The stock clocks are as advertised (880/950), but fortunately I can use AMD GPU Clock Tool to lower them, as my card was only stable at 864/920 previously. I'm going to start there and work up using UT3 demo as a stability testing platform. (since it's alot more fun than ATI Tool) Here's some info dumps from the BIOS:

All this and I'm not even drinking yet....

EDIT: For some reason on my card it brought it up to 1.3v in 3d, even though it's advertised as 1.25. My previously stable speeds seem stable, so I'm going to start ramping up the GPU.

[003]

(for us "old" xt owners with the crappier ram)

I'm curious... what do you mean by this? How do you tell if you have the "crappy" ram? Mine does 1035MHz @ 820 core. If I lower the core speed I can get it stable with even higher ram.

You don't have the crappy ram. Mine craps out anywhere after 918Mhz.

[003]

Ah, ok I have the 1gb GDDR4 pro, and I keep the pro bios, because it benches higher than the XT at the same speeds, and I can already do 820/1035 perfectly stable with the pro bios using atitool artifact scanner for 2+ hours (and still no failure). Of course I am using a thermalright hr-03, as5 and a ghetto mounted 120mm fan I may even look into lapping the hr-03, it seems to have a pretty crappy finish on the contact surface. (compared to say, a scythe ninja)

Once ATITool is updated and voltage adjustment works, I assume I will be able to scale even higher as I am on all stock volts with the card currently.

Ya I'm not gonna upgrade my cooling so temps more of an issue for me but I expect the same. Hope W1z is working on it still; been awhile since a new beta. Maybe we should be posting in that forum...

Oh I missed this earlier. 1.3 eh? how are temps? Mb ur testing that as I type. Good luck!

And I wasn't aware of any differences in RAM types...not that any of this applies to me and my 1GB anyway

up to 897 from 864 sofar and still testing... more info to follow. :cheers:

[quake6]

Can you change voltage in ati tool?

[WrigleyVillain]

Can you change voltage in ati tool?

Yes thats our only option and a crappy one at that...all waiting for the next beta at best.

I should just put this stuff in my sig.

I want a 512 now...or mb a 8800GT...or mb..or mb...sigh.

Truckchase! nice job man. Did you flash both cards installed, or pull them out one at a time to flash ea? The readme file shows flash instructions for flashing two cards installed (or just flash mounted in diff slots?) with out having to remove them one at a time to do the flash?

Needs a 12 pack tonight

Thanks! I'm a poor guy, I only have one card. I'm just trying this modded BIOS out to increase overclocking capacity due to the increased voltages. I'm still testing, but I'm over 900Mhz now on the core and I've got my memory bumped up by 30Mhz higher than my previous high as well. This BIOS definitely ups the vMEM as well.

If you wanna flash xfire, just make sure to specify the adapter number. I'd do both at a time. Here's the command syntax for atiflash.exe:

Even tho that says 3.39, I used 3.43, which can be found here:

Flashed the '880c950m' bios only (visible) differences:

Vcore 2D= 1.10 (up from 1.00)
Vcore 3D= 1.30 (up from 1.20)

I'm on water, so not so consernd.

Testing in progress - starting point 870 (max stable on 1.20). should hit 900+ if the heat don't get me

Yeah it should. Good luck!

[roger_h99.nor]

Initial findings (using Aquamark because it's fast and gives a general idea of where the limits are);

Could loop AM at 910. Card barely breaks 50 degree C (core temp).
At 918 AM crashes 1 out of 2 times. So between 910 and 920 seems to be max OC at 1.30. Since heat seems to be no issue (yet), i'm tempted to try the 1.35 bios.

Something odd though - why does the bios raises the 2D voltage? Maybe it have something to do with the card itself - only alowing 2D +0.2 as max 3D voltage. Seems strange to me.

Thanks! I'm a poor guy, I only have one card. I'm just trying this modded BIOS out to increase overclocking capacity due to the increased voltages. I'm still testing, but I'm over 900Mhz now on the core and I've got my memory bumped up by 30Mhz higher than my previous high as well. This BIOS definitely ups the vMEM as well. ]

Yeah, me too... Although I will be eating a lot of pb&j samish’s for awhile.
Great stuff, thanks for the Flashing info.
