X800 fuses data for unlocking

[dolf]

Config DIE Fuses: 0xEFF37FFF und Config Substrate 0xFFFFFF1E
Its a R420 AGP

Is there anything possible with a hardmod?

Regards

The chance is not fantastic but with these Config Substrate: "0xFFFFFF1E" probably something could happen. I would recommend to try connecting the bridge. If you done it please post again the fuses.

 

[highshot]

Sounds nice. Will give it a try. I was wondering about the 0xEFF37FFF and thought, that there won't be a chance.
The clock speeds for XT PE level is no problem at all. I am currently at 530 GPU and 630 RAM (Temperature 42°C)

I had X800XT AGP and it was with 1.6ns. The timings for X800XT and XT PE are equal.

Okay thanx.....flashed the card is working fine

Success--800GTO runs like an XT--and a question

I have a new Sapphire "blue" x800 GTO AGP with an R480 chip. Added a (modified) Arctic Silencer 5 and used dolf's bios mod (thanks!!) to open 16 pipes successfully. (Fuses were all F's; xxx9F as described in here.) ATItool got me to 531/594 MHz separately, but longer time at 520 MHz GPU or 550 MHz memory causes crashes (at ~ 60 C). So I think I'll hold with the 500/500 and load that bios.

Does the BIOS also have to be patched to get the card recognized as an XT? Or do games just try to run it as fast as possible, using the frame rates available from the hardware and GTO OC'd bios? BTW, if it matters, I seem to be stuck on v. 6.6 Catalyst drivers--later ones hang my computer in standby and kill my screen rotation.

Of course if the ID's are moded your card could appear also like "Father Christmas" but the performance should be almost equal. The card has core power supply predicted for 12 pipes (only 3 MOSFETS) and probably some limits comming from the Realto max. frequency. If your card is stable at 520/540MHz just use OC2 BIOS with these speeds and be happy. If the card could go higher - OC it additionally with RivaTuner, ATITool or something else.

 

[rocketman4321]

That makes sense--all my core overclocks ended with a hard crash, which seems like power available to the card. I'll stay at 500/500 with the OC1 bios. Thanks for the help and the firmware!

Does that apply to x800 pro VIVO AGP too....Does it also have 3 mosfets instead of 4(as in regular x800xt).....and i'm putting my card on stress by running it with x800xt bios w/ 16 pipes and higher speeds(500/500)... which it is not designed to handle..

X800PRO VIVO in fact is X800XT / PE and it has 6 mosfets (originally). X850 Series has 8 mosfets (the 12 pipe cards usually have 6 instead 8). 6 mosfets are absolutely enough for 16 pipes and X850XT PE speeds (I had X800XT PE which worked with 570/600MHz). It is not problem to run with 16 pipes on board predicted to feed only 12 but the heat dissipated in the mosfets if higher and it would be good idea to cool them with heat sink. It could be problem at higher speeds because the power supply circuit is not so stable like it has to be.

Hi guys, i need a help on this.

Model SAPPHIRE X800GT - R423 - 128 MB. Blue PCB Azul

Can i mod it?

Okay Thanx once again Dolf...u do really know u'r stuff
So i assume, this card is exactly same as x800xtpe....just downclocked and some pipes disabled for probably marketing reasons??

Actually just was a little bit more concerned about my x800pro as this card dosen't have any warranty...so just wanted to make sure, i don't stress it too much, that's why i'm running only on XT speeds, i'm pretty sure this card can go upto XTPE speeds or even higher as it looks identical (and has the same cooler w/ copper base) as the orignal BBA x800xtpe..

Just test it. The good "old" news for X800PRO VIVO AGP is that they didn't have locked quads on hardware level (just BIOS) and 100% can be unlocked to 16 pipes. The reason for the locking could be bad memory which couldn't reach the XT or XT PE level, core which can't reach 520MHz and more or bad pipe quad (it happens in 5% of the cases or something like that). The same is equal for X850PRO VIVO AGP but the success rate of unlocking is app. 80%.

hi again

so It`s me again. I have a simple question: what mod. bios sould I use for my card to have a stable one ? (with 16PP). Peace!

 

[dolf]

I would flash it with the attached BIOS using the following command line in DOS mode:

atiflash -f -p -newbios 0 bios16.bin


Good luck

 

[Anusha]

Dolf, can you edit the X850XT BIOS you gave me (in the bootable ISO image) and make the core/mem clocks 500/520 respectively and upload it back?

I flashed my card with the X850XT bios, and it worked! But in Vista, for some reason, I can't run the core at 520MHz. It's unstable. Could be a driver issue. Anyway, I would appreciate if you can do this for me. I'd be very happy if you can give me it in an ISO image.

Please, dont forget me

Is this 61D a problem?

You are not forgoten but we can't help you unfortunately. CONFIG_DIE_FUSES 0XEFF33FFF are problem because they show that only 8 pipes are possible.

Sorry, its me again

I read of people where only the substrate fuses changed. The die fuses not.
Config DIE Fuses: 0xEFF37FFF und Config Substrate 0xFFFFFF1E

What bios do I have to flash? I got the 2.0 memory.

Thanks!

Absolutelly right in 99.9% of the cases no change in the DIE fuses. But there is one case (I can't find it in the forum) in which the connection of both bridges resulted in DIE fuse change (it deppends on a bottom side bridge configuration). At present you dont need to flash or if you want flash X850XT or X850XT PE BIOS and the result will be X850XT / PE but with 12 pipes (be carefull with the fan with single slot cooler).

 

[highshot]

will give it a try.
The card is from 2005 and has a red pcb.

I will flash the x850 bios, because of the ram timings.
At least I can mod it to a x850Pro. The fan is no problem, because I'm using a self-made watercooling for mem and gpu

Can a hard mod help to change it?

Thanks for the suport!

 

[highshot]

just found the case you mentioned. He "reanimated" 3 (!) cards by bridging the lasercut. But all of them had an E instead of my 7 in their die fuses.
Do I get a performance-gain by using a X850XT-PE bios?

I looked around and nowhere was mentioned for what GPU they are for.

 

[dolf]

They are for AGP (R481) or PCI-E (R480) be careful prior to flash and check the GPU type first .

 

[tb]

thank you dolf

Thanks dolf, I flashed may BIOS again and this time seems to be stable.Can you tell me why I have mem&core frequencies that low ?? Is like I have a x800 non pro instead of a x800gto.
Peace!

Can you resend that email? Had to change my email and didn't know that I had put the old one in here. :shadedshu
