The HD 2900XT Info Thread

[AKAeric]

My cards have two different BIOS revisions. 100 and 103.

100
103

Not much that I could find out, although the 2d clocks seem to be in the first few lines.

113-B00602-100 R600 GDDR3_8Mx32 512bit 512MB 507e/514m

Hey open that with wordpad

[AKAeric]

I did.

Unable to find where the 3d clocks are hidden. What I was thinking was to compare the 2900pro and 2900xt BIOS and see if we can spot where the clock speeds lie.

I think they are in the three lines here. At least thats where they lie in the 1950pro bios.

Frequencies will probably be in HEX, so better use binary/hex editor. Another thing to watch out is for th big/little endian.

The links that you posed above (100 and 103) what are they? Is one for XT and another is for Pro? An which one is which?

[AKAeric]

no. both of those are for 2900xts. The 100 is for the first card I bought, the day they were released. The 103 is the second card, bought in late July.

Here's a text editor if you're interested. I'm going to have a look at it while I'm at work. I may be able to learn this.....I have a strong math background from studying engineering (haven't graduated, tech support ATM)

[AKAeric]

I already have that same editor. It just pretty much the same thing as wordpad.

Rabit says the clock table starts @ 0xAB0E and ends at 0xAB67.

Starts with the Y and ends with the H.

Dumb question but, how far can I go with my OC? What's the max temp??

[Rackerz]

OC is usually limited by temperature, mine will do anything upto 830 on the core until it starts to get too hot and crashes out. If I want higher than 830 on the core then I need to adjust the fan speed which get's quite loud.

At 850/950 my 2900XT does not like to exceed 65c, it may go to 70c but I think it's 65c.
