X800 Pro VIVO to XT PE Bios Mod

[sacharja]

Hello,
I have a Sapphire X800 Pro ViVo with 1,6ns and flashed it with a bios of XT by the modified flashrom. After reboot when no driver is installed 2 uknown devices are recognized, how it should be. After I installed catalyst the card is correctly recognized as X800 XT and Secondary Device, but there are 2 more devices (both unknown "driver cannot be installed for this device").

Means with the new firmware and after catalyst installation there are 2 unknown devices that are not existing physically.

Has anybody recognized the same?

It worked! 16 pipelines. Had to force the bioschange (-f) in flashrom, but then it did the job. Thanx!

Modified Flashrom did the trick

Just to say thanks to Dan for putting me right. I hadn't used the "modified" flashrom and once I found it I ran through the process again and it worked! Yeah! 16 pipes now

Great instructions, great forum, great advise! thanks again!

First time post so go easy.

I’ve tried the softmod on a Connect3D X800 VIVO card I got from ebuyer. I removed the heatsink and fan and theirs no laser cut.

I’ve run the BIOS mod for an X800XT and ATITOOL says that I’ve unlocked the four pipelines, I now have 16, but in no way can I get the card to anywhere near XT PE speeds.

I’ve tried most of the BIOS’s for an X800XT, all with out success, ATITOOL crashes in a few seconds when I run scan for artifacts. I’ve started at an XT core and memory speeds and gone backwards trying to find a stable overclock speed. I’ve tried the 500/500, core/memory BIOS, again with no luck.

The only BIOS that works is the original BIOS, clocked at the original speed of the card, perhaps I’ve just got a card that doesn’t clock very well, if at all.

Unless I’m doing something wrong, but I think I’ve followed the guide carefully and didn’t encounter any errors when flashing the card.

So anyone with any ideas?

Did Windows install drivers for eh ATI Rage chip? Some people seem to have problems with the Rage chip not working and becaue its not working another device wont show. Try another bios, and see how it works. You might also have to get drivercleaner to completely get ride of everything that has t do with ATI and then reinstall your drivers.

Did you try to overclock the card without the pipes enable to the XT PE speeds? If the card just can't handle the the speeds use the X800Pro Vivo 16P bios , that is just the the pro bios modified for the 16 pipes.

hello all,
i've got a Sapphire x800 pro vivo (pci-e) and i've flashed the bios with a asus X800 XT PE (PCI-E) (asus seem the only one's to have the bios (xt pe) for a pci-e card.
after flashing the speeds are running correct 520/560 (atitool) but windows sees the graphcs card as X800GT and not x800xt pe, could that be changed some how, every thing else if fine and stable.

Thanks all in advance

 

[dil]

1 more question can i unlock the 4 pipelines from 12 to 16 (i cant find a bios for it)

after flashing the bios to x800xt pe the pipelines were at 12.

Thankyou

I have the same exact card and the same exact problem. It says X800GT after I install the asus x800 xt pe pci-e bios and still says 12 pipelines...its very strange. Also, once windows automatically installs "x800 GT" drivers, the clock speeds in ATI tool become symbols like "=#%" or something like that...I'm using the modified flashrom and everything...I just don't know what I'm doing wrong. Maybe I need a different bios. I've also tried the sapphire x800 XT pci-e bios and it was pretty much the same thing except with the non PE speeds before it loads the drivers and becomes...symbols.

 

[djbbenn]

Just try another bios. I have heard of them dectecting as x800se, and that meant you have the wrong bios. So its should be the same if it detects it as a GT.

i have tried 4 different bios's (ati) x800xt, (asus) x800xt pe, (asus) x800xt, (Sapphire) x800xt, according to ati tool the core and memory are at the correct settings but windows wil not recognise it as a x800xt or x800xt pe.
the bios flashes i have used have been for the pci-e as mine's a pci-e (sapphire).
and i'm doing this in win 64bit! could that be somert to do with it. or could someone recomend what bios i should flash it with.
Thanks in advance

(can i use agp bios's on my pci-e, i havent tried that)

Like I mentioned earlier, I have the same exact problem as you and the same card, sapphire x800 pro vivo on PCI-E, and I'm not on 64bit windows. Although I did mention that the clockspeeds looked verrry strange in ATI Tool after windows loaded the x800 gt drivers or whatever but then I switched from using modified flashrom to the ATI Flasher and that still gave me x800 gt but the ATI control panel actually works with it and everything seems stable. My 3D Mark 05 scores went up 600 points but it still says 12 pipelines...and I'm unsure how comfortable I am with the bios being listed as X800GT...

So yeah, I'd also love to know if it would be okay to try an AGP bios with my PCI-E x800 pro vivo.

 

[djbbenn]

DO NOT use a AGP bios on a PCI-E card! That will mess the card up. Did you guys hardmod to get unlock the pipes? You have to hardmod the PCI-E versions before flashing or else it will only show 12p cause thats all there is. If you don't hardmod, it doesn't matter what bios you flash, you will not get the pipes, because they are physically cut on the chip. Where it showing up as a GT, I really don't know. The GT was just released, and I don't even think you can get the GT bios form this site. The GT is also based on the R480chip with 8p, while the X800pro's are the r420(AGP) and the r423(PCI-E). So I don't know why its showing as a GT. Sorry but I can't help you there.

[dil]

i have not done the hardmod, i have been looking all over but i need instructions on how to do it, could you post a link in you know one where i can follow the instructions for the hard mod.

will i still be able to hard mod it now eventhough i have flashed the bios to the asus x800xt pe or will i have to revert to the original bios before hard moding it.

Thanks.

 

[djbbenn]

You don't have to revert to do the hard mod. To to the mod simply take the heatsink off and get a conductive pen and join where you see the laser cut. Theres a pic of the laser cut on the softmod site.

the only pic i can find with the lazer cut is the one at the start of this forum page, i have looked all over

this is one with out the lazer cut (taken from the start of the forum again)
http://img.techpowerup.org/050825/r420nolasercut.jpg

what should i bridge together

with the lazer cut

1 2
* (* is lazer cut)
3 4 5 (4 is big blop in middle)



or without lazer cut:-

1 2 3 (no 2 is the big blob in middle)
4 5



please help

 

[dil]

highwind86 have you found where to do the soft mod on the softmod site, i cant find it anywhere all i get is the old graphic cards.

Did Windows install drivers for eh ATI Rage chip? Some people seem to have problems with the Rage chip not working and becaue its not working another device wont show. Try another bios, and see how it works. You might also have to get drivercleaner to completely get ride of everything that has t do with ATI and then reinstall your drivers.

I´ve tried flashing it with the ati bios, screen got black and I flashed it back.

Same thing even after a new windows installation. If I install the driver directly from device manager I click at one of the 2 unknown devices (XT and XT secondary) and say install driver. During installation it finds 2 more unknown devices which remain after XT and secondary is installed and which cannot be found a driver for.

Has nobody the same problems with a tweaked Sapphire?

 

[djbbenn]

dil: Connect 1 and 4, or the top circle with the bottem on the left side of the big circle. So it just connects the two dots with the laser cut in between them. Then do the softmod. If you get artifacts, just flashback to orginal bios, you shouldn't have to remove the mod but you might. Not a big deal.

Come to think of it now, I think I know why. Some of the Xt bioses don't have the rage chip in the bios, but windows finds it, but can't install it because its not enable through the bios. Try a XT PE, or another XT bios and see if that clears it up.

-Dan

 

[sacharja]

Yes, that´s a good idea. There´s a symbol of a chip in device manager of the 2 unknown devices.

So what can I do? I tried flahing the sapphire PE, but got artifects and green textures. With the original ati bios I got only a black screen. Which can I try? I´m frightened of beeing unable to flash it back

 

[dil]

djbbenn: i have opened the heat sink have seen the lazer cut, just to clarify i need to connect the top left to the bottom left with the lazer cut in between, connecting 1 and 3 and nothing touching the big blob at the bottom and not touching the lazer cut.

i'm just making sure because you said to touch 1 and 4, and then "connects the two dots with the laser cut in between them"


and what do you recomend using to touch the dots together,


thankyou for your previous posts they have been a great help.

Don't worry about having to do a blind flash...did you try all of the Sapphire XT PE bioses? There are three I believe. Also, try the ATI X800PRo Vivo 16p bios, if nothing else works.

Just the top left and bottem left dots yuo connect. Te ones with the laser cut between them. I would use a conductive pen, or paint, pens easier. If the mod doesn't work you can just scrape the connection away with a knife. Heres a link that I looked up that might be able to explain it better for you. Good luck dil.

hi djbbenn,
I have done the joining with a conductive pen, and still stuck with 12 pipelines. the system still reports x800gt for some reason i tried a different bios to see if there will be any change. nope no change.
could that mean the pipelines are locked within the memory or somert like that.

(just to let you know nothing is connecting to the lazer cut and i did scrape the top left and bottom left with a knife to see the copper heads and used the conductivity pen to do the joining)
