Looking for someone who knows how to recover from bad flash and has R423 card

[Steevo]

OK, when i use atiflash -i it shows 0 and 1 adapters in the system.

Device 1 is a RV423, no matter what flash, etc...
BUT, I have it identifying as a X800XT PE and R480 BIOS according to everything else. And it is keeping 5D4D, despite any other flash I apply. I am believing that there is some sort of mechinisim to keep you from downgrading the BIOS, at least on this card.

I had success using 4A4B as one of the first flashes, and gettting the 16 pipes, but no driver would install. I believe that was due to a bad subvendor-subsystem ID.

By looking through the *.inf files for installation, you can find groups of ID's to try, and so far I can tell my card it is a 7000 and it still works, not well, but it works. When I say that I can tell my card that, I am flashing the BIOS to adapter 0.

Now for the next part I need a utility to completely erase the BIOS on this card or that will allow me to flash a BIOS of nothing but 0's.

Do you have 3dmark 2005 (or 2003)? If so, and you have had the card working with it identified as an X850 card, try testing performance with a 55xx ID (R423/430) compared with a 5Dxx ID (R480). After testing it, post the scores for each. As far as I know, the scores should be different between the two different types of ID's, but I don't know which will be faster.

It is the same with oth BIOS's.

4970 ish. OC'ing is the same. It works and looks the same.

as i said before I am going to try and run through all the ID's and find a set that will work with the 4A4? card ID, and also try to get the GD BIOS to change. Even if it means overwriting the BIOS and possibly damaging the card. i want to have those 16 pipes.

For ANYONE out there, if you have a X800XL with infineon memory, PLEASE post your BIOS for us.

Thanks.

So no speed change when changing from R423 to R480 in the bios? That's in line with what someone else tried: http://forums.techpowerup.com/showthread.php?t=6430

They got no performance boost from changing the ID from that of an R423 to one for an R480. Before that, they actually even tried the bios from an X850 series card and it worked. They did get lower overclocks, too, which is just like when I tried to use certain X800 series bioses for R423. The difference could possibly be just a result of different memory timings being used, though.

It looks like it is safe to at least identify a card as having an R480 and maybe even use the bios from a card with an R480 as long as you keep the clocks low enough.

I try to flash card with R480 with the bios from 423. the only problem is the card has '!' sign in the device manager and isn't recognized by atitool

BBA Radeon X800 Pro VIVO PCIe

I did some testing with my card and found out that it appears to be locked to a BIOS with a device ID of 5549. I took the cards original BIOS and made changes to the IDs and the card simply would not work (wouldn't activate the monitor on boot up, etc). Then I took an XT BIOS and changed it to have the same IDs as my original BIOS and it worked (this BIOS wouldn't work before the changes to the IDs)! Unfortunately it didn't unlock the extra 4 pipes, though.. what does this all mean exactly? I've never heard of someones card having hard locked device ID.. btw. I've attached a screen shot of ATITool.. I need an explanation of it as well, like if it will ever be possible to unlock the extra 4 pipes on this card. (note: I haven't been able to unscrew the heatsink from my card, so I can't check to see exactly what core it is, or if it's been laser cut.)

I have the very close Video Card here: Sapphire X800 GTO 256 AGP (400 / 490).

I think not many ppl bought this card cus his brother GTO2 . But still I would really like to mod it either way. My core shows a R430 with ID :554F on ATItool 2.4 (dont know if I should use 2.5 beta 8 ?)

At this point with the forced stock cooling i can OC to 440/540 until Artif.

Anyway I am thinking to pencil mod it since it has a simlar to excact likeness to X800XL. But did anyone did that? I want to gather more info on GTO R430 so my goal is to achieve(500/600) I dont know if I can do that but I just bought my 2b pencil too!

I want to try the bios thing too but I dont have pci v-card...

Everyone saying that Sapphire GTO1 is not moddable to 16 pipeline so I already forget it already. But I really want a 500hz core since my core temp is only 62 at load.

SO, what's the deal?? did you get 16pipes and the drivers working?? which set of ID's??

anyone, the thread owner, or anyone else, still around???????

I haven't posted anything else because I was waiting for others to post something. I don't really have anything to try for myself. I already have a 16 pipeline card with an R480 chip identified as such in the bios.

 

[ryboto]

ok, well, i was just waiting for someone to reply with a set of ID's to try. I've got a pci card in case things go bad. If I have time to install my floppy drive, i might do it tonight, or tomorrow.

I haven't had time to try to hack a set of drivers to force on when it identifies as having 16 pipes. Too busy building this monster

We REALLY need someone with a X800XL Infineon BIOS to post the BIOS so we can work on that.

That is the new task.

well, what ID's should I use?? i've got a HIS x800xt bios, and I was going to use the ID's from that...yay, or nay?

What was it you wanted to do again? I can't remember at the moment and don't have time to look for it.

 

[Steevo]

I found this ATI PCI-E X800XL BIOS (supposedly) with Infineon memory. From my understanding it SHOULD have 16 pipes enabled.

I will have to wait till I get home to check unless someone wants to do it for me. I can also flash it to my X800GTO that has Infineon memory.

I just wanna know what ID's i should use that would yeild a 16 pipe card.

i'd use it, but i've got an agp card, and i don't think i have infineon memory, i'm almost certain it's samsung.
