Guide to Radeon X800/X850 bios modding

Hi,
I want to ask how can I mod the X850XTPE BIOS to controll Sapphire GTO2's Fan: Which rows are for this.Thank you!

I have no clue. BTW, what do you want to use the X850 XT PE bios for? The only thing that is different from what you can do without it is that ATI Overdrive is available. If you are already using the X850 XT PE bios, just save the default memory timings to a profile, then flash back to your GTO2 bios and use the X850 XT PE clocks and memory timings in ATITool. ;) I've tested this out and I get the exact same score as with the X850 XT PE bios. You can even use the mod for changing the name if you still want it to say it is a Radeon X850 XT Platinum Edition. That's what I do. ;) Besides, it is probably best to only use those clock speeds when you are running a game that would benefit from it.

BTW, on my X800 GTO2 the only memory timing settings in ATITool that are different are these:

MEM_TRP - default is 6, XT PE uses 5
MEM_REFRESH_RATE - default is 0x3B, XT PE uses 0x1E

Those account for the 15 or 20 point difference in 3dmark 2005 scores when using the X850 XT PE bios.

Hi, why the mod of ID of my x850pro 4B4B to 4B4C make a bad 4A4C ???
I want this mod because the card is recognised x850xt pe
 
:slap: how do you all get scors that high,, my highest was 1934 in 3DMark 2006 ?? ahh nvm:roll: i see you are running 06 and not o6,, i will get o5 and see how this x850Pro Moded to a x850xt set to Pros clocks:D
 
3DMark 03 x850Pro Not Moded all set to defalt 10820
3DMark 03 x850Pro Moded to x850xt all set to defalt 12355

Hi,
I just bought my Sapphire 800GTO2 LE but it is with R430 and 12 pipes and I didn't find any power connector except 4 pin socket looks like flopy connector just smaler. Is it normal?
CONFIG_DIE_FUSES: 0XFFFFFFFF
CONFIG_SUBSTRATE_FUSES: 0XFFFFFF9F
Can I modd this card to 16 pipes?
Thanks
Saras

Yes you can, I flashed mine (same as yours - r430/2,0 ns mem) with the modified gto2 bios and it works fine.

Does Your card has any power connector, or it uses from pcie slot?

My card is Sapphire x800GTO2, blue PCB, no power connector, R430 and samsung 2.0ns memory (GPU and Mem specs came as a conclusion from my max OC capabilities 435/560)
Original bios was: 11x-cc600asa-001, flashed it with the modified gto2 bios and all 16 pipelines are now unlocked.
My only concern (and I already posted this in other thread on this forum) is if the modified bios is fully compatible with my card (given r430 and slower ram), as I guess the modified bios came from the "real" gto2 - with r480 and 1,6 ns memory.
Anyway, my card is OK since flashed, no stability issues 3dmar05 score raised to ~5100 @ stock speeds, while OC'd result (435/560) is ~5600

Hmm, what kind of cpu is that on? Mine gets 6414 at X850 XT PE clocks (540/590); well, also the X850 XT PE memory timings, too, but those only make around a 15-20 point difference. My CPU is an Athlon 64 3200+ (Venice core).

My highest score I've even seen on my system is 6633, with 550/600 and some modified memory timings, although it wasn't 100% artifact-free, though. I've tried also overclocking my cpu and memory before, but it only makes a minimal increase in the score - about 30.

It's Athlon XP Barton 2500+@3200+ (2,2GHz) here. A bit of a bottleneck I think. 3DMark05 CPU tests are unwatchable...
I used the cards original memory timings, which only differ in one parameter compared to the XT PE BIOS I found: tRP=6 instead of 5 (XT PE).
Setting it to 5 now with the above core + memory timings work fine. Score raised in fact to 6455 points...

EDIT: Oh, I didn't touch this one:

If you have such concern post your original BIOS and we will mod it for 16 pipes. Then you can flash it back and the only difference will be the number of the active pipes.
Unfortunately I will be out for few days and will return in friday. If you can't wait till friday ask somebody else to do the mod or do it yourself :) .

Thanks for the offer, I think I can wait until you're back :)
here's my original bios

Hi. I have a problem. I just can't get my card (x800, R430) (R423 in rabit?!) to get 16 pipeslines. Maby it can't but here's the data from atitool:

NEW BIOS:
CONFIG_DIE_FUSES 0xFFFFEFFF
CONFIG_SUBSTRATE_FUSES 0xFFFFFF9E
CONFIG_ROM_FUSES 0XA60

OLD BIOS:
CONFIG_DIE_FUSES 0xFFFFEFFF
CONFIG_SUBSTRATE_FUSES 0xFFFFFF9E
CONFIG_ROM_FUSES 0XA61

But still only 12 active piplines. Have I edit the bios file wrong or can't my card simply unlock those "extra" pipelines?

/Rob
 
from what i have read, unless your CONFIG_DIE_FUSES says 0xFFFFFFFF, then you can not unlock to 16 pipes.

It looks like you did the mod right (the goal is to get a zero for the last digit of CONFIG_ROM_FUSES). Unfortunately, it doesn't look like you can unlock the pipelines.

Hi, I was wondering if you can mod my bios for my x800gt. I have what atitool says about my card in the attached picture.

Thank you if you can get it working or not.:)

With those details, I think others will agree that, its unmoddable.

Probably you will remain with 8 pipes but you should try at least. My advice is to remove the cooler and to connect the right bridge. After that use the moded "bios12.bin" file to flash. Don't forget to use modified flashrom. Finally post your fuses again - after the hardmod.

Good luck

Read through this entire thread... couldn't find any details about unlocking 16 pipes on my card

Sapphire X800GTO AGP R430 core

Here's pics of the ATI tool fuses and such. Attached a copy of my bios dump from ATI Tool as well.




Still a little confused on what I need for the pipes to be unlockable...
Did read that the R430 cores had trouble overclocking... and I have experienced that... Can't seem to get past 440core and like 530mem so I'm pretty sure that ATI Tool isn't lying about the R430 core.

To unlock just use modified flashrom with the following command line: flashrom -f -p 0 (zero not o) bios16.bin and the modded BIOS attached.

After flashing with modified flashrom your CONFIG_ROM_FUSES should be changed from 0XA61 to 0XA60 (it is must) in order to have 16 pipes ;) .

Good luck

Thanks a bunch. Just got the extra 4 pipes unlocked with that bios dolf.

here's some new pics from ATI Tool
