X800 GTO² to X850 XT BIOS Mod

Time to revive this old thread.

I have a powercolor, x800crap, PCIe, 350/400 clocks, R430 Core, 12 pipes, 1.6ns ram, ati theatre chip on it. I would like to know if it can be flashed to an x800xl??

Here is a pic of the core, I don't see any laser cuts, but I could be wrong.

Please let me know if any other info is needed.

Download ATiTool here: http://www.techpowerup.com/downloads/436/ATITool_0.26.html

Hmm ok. I don't really care if I unlock the extra pipes, I mainly want to run that 600 MHZ ram faster than 350MHz.

Well, the x800xl uses 16 pipelines from what I remember. I'm not sure if you need to add voltage or not, but have you tried overclocking it first to see what it can do?

Not yet, I think I will let ATI tool run and see. I think this is a powercolor x800 bravo model although it seems to be built like a vivo model minus the yellow plug.

edit - the mem went to about 530 before getting artifacts. I ran it at 500mhz for about 4 min with no artifacting, then shut it down.

So now to figure out if I can flash it or not, doesnt matter too much if it dies, I am pretty much doing this for the experience, I have an HD3450 sitting in an unopened box

You can edit your memory timings on that board, one of the last few able to do so (don't do so unless you know what you are doing). I tweaked with my for a few weeks to finally get it set just right, then flashed a custom BIOS to it.


What is you core clock? That makes a crapload of difference, and also will tell you if it is able. I will have to review some of the thread but most cores that could unlock managed to reach much higher speeds than the defect or early revision dies.

Wow busy week/weekend.

The specs list the core as 400mhz default and memory as 350 mhz default. However atitool reports something like 397 Mhz for the core and 349mhz for memory.

The card is a powercolor with dual dvi, 1.6ns ram and rage theater chip on it, but with those default clocks I think it maybe a plain x800 or x800bravo.

pretty much it, I put my ati silencer 5 on it, probably just sell it for a few bucks, be nice though it could unlock to an x800xl though.
