X800 GTO² to X850 XT BIOS Mod

Can't answer your question about the agp issue but you definitely will have to get a pci card to reflash the bios; that is unless you can are very good at typing blind. Is there a used computer shop near you where you can buy an old, cheap pci video card? Any will do. You just need it to display ASCI characters on the back and white boot up screen so you can type the flash commands. Hope you saved your old bios file.
 
ok

ya i tryed to get it to boot up start up disk and type blind would not boot
that far and ya lucky me i did back up bios. do you think its posible i fried the video
card?

thanks brad
 
It's always possible that you fried the card but I wouldn't jump to that conclusion. The bios you attempted to upgrade to, is it something that is commonly working for other folks? What is it designed to accomplish, just overclocking or opening up more pipes as well?

Try taking the card out of the slot and then put it back in. Maybe it would reset or something. Things inside an atx case often get trickle voltage even when you don't think they are active.

I still would pick up an old pci card if I were you and try it again when you can see what you are doing.
 
you can 'blind flash' back to the original bios.

The steps of this are to insert the floppy with atiflash, and your original bios,
turn on your pc, and wait for it to stop loading from floppy
type the following: atiflash -p -f -newbios 0 [biosname].bin
wait for the floppy drive to stop working again,
remove disk, and restart.

Which bios did you use?
 
i did woot

I thought i was out of a ati x800 gto agp. had to go to bestbuy to get a pci card
and after alot of work was able to fix it with old bios. then used winflash and this bios that
some one posted some where for agp cards and unlocked it.

thanks for all your help guys.

i use the catalyts, they've always worked well for me. The omega drivers work great as well though. I'll probably have a play with them when i get back home, and run some benchmarks and see if there's any difference.

There is a 'modified flashrom' about, that basically uses the -newbios tag without you having to type it in. It just tells the flashing software to completely rewrite the bios, instead of keeping some settings. I'll talk to a mod and see if i can modify the post.

Good luck ;)

:D :D Thanks a lot! The hint with the "-newbios" tag solves the problem. Now it works well.
 
Hello, I'm knew around here, i have a GTO2 ..this one http://www.newegg.com/Product/Product.asp?Item=N82E16814102645
It has 16pipes a R480 core and an x800xl bios.
I thoght it should be a x850xt with a x800xl bios and cooler. And i flashed it with the X850xt pe bios... It froze when i opened the spinning cube in atitool. Then i flashed it with the x850xt bios...same problem... Of course, i didn't save my original bios (damn smart). and finally.. i started to read the forums... I wish i did that in the first place. So i ajusted the speeds and i got it working at 505 gpu and 610 mem...
So, is it normal, to be that low ... a mean the gpu. I thougt it could go higher than 540mhz...
What is wrong or what did i do wrong... Does anyone has a modified bios for this type of gto2, or at least an orginal one?

PS: I have an Ati Silencer 5 rev 2....so there's no heating problem
 
go to Ati bios collection and pick the suitable bios for your card.
 
hmm... i dont' know if the dual dvi bios listed there is the same as my dual dvi+vivo board..
 
hi

any anyone tell me if this version can be overclocked 21067-00-50

else i ll be buying 21067-01-21 <<(this can be overclocked right ??)
 
wtf is it? Serial number?

If it's a graphics card, then yes, they can all be overclocked.
 
Yes, it's easily done on that card. It has all the same physical components.

For some reason flashing to that bios can cause the fan control to stop working correctly, so there's a modified x800gto2 bios, that will make your card show up as an x850xtpe, while still giving you perfect fan control.

I can send you the bios when you get the card if you like.
 
21067-01-21 refers to the Sapphire manufacturers number. (one of my earlier posts explains the significance of this number)

My gto2 is mfr# 21067-01-21 = R480 core, Red PCB + pwr socket.

I flashed it to an x850xtpe & with an AC Rev5 silencer I'm getting 28C idle & 48C max temps.

I must have used the same bios infrared will kindly send you as I've not had an fan probz.
 
Ok, here's the bios.

It's for the Red PCB, R480 core, 1.6ns memory, 1xDVI, 1xVGA, no VIVO.

The vivo feature can be added by opening it in RaBit.
http://www.softpedia.com/get/Tweak/Video-Tweak/ATi-Radeon-BIOS-Tuner.shtml

It uses stock clock speeds for the gto2, but again, they can be changed to whatever you want in RaBit.

Enjoy!

ps: Thanks go to shadowflare for sending me this bios

For the vivo + dual dvi version, it would be better if someone would send me their bios for that and then I could do the same mod on that bios.
 
i cannot open Rabit.it says that there is a problem with rabit.sys driver or smth.
what to do?
 
ok.i used 1.7 version and it works.
 
can someone please send me an original gto2 100130VIVO(dual DVI + VIVO) bios.
 
Hey guys,

I'm a newbie to this overclocking business. I just got the GTO2 (Limited Edition) and tried flashing the bios with apparent success. I rebooted the computer and all 16 pipelines were unlocked. My display driver read as a Radeon X850 series card.

Then I tried testing this out by downloading the demo version of Need for Speed Most Wanted and the image looked messed. The text was crap, artifacts everywhere, and graphics out of place. So I rebooted, flashed back to the old bios that I saved, and tried the game again...and voila, it worked.

Can someone tell me what I'm doing wrong? I'd love to have 16 pipelines and overclocking at 500+ like everyone else here.

Appreciate any help that comes this way.

Well, your problem may be that your GPU & your GDDR3 memory are both running way too hot or it don't have enough volts.

If you try going after market cooling, it may work out for you. I never had that problem, & pushed my GTO2 I used to have @ 630MHz GPU & 1260MHz GDDR3 - what more do you ask for with that insane Rock Stable OC ;) Though I had it water cooled mind you, which helped.

Thanks XP, I WAS using ATI Tool to test my max speeds before trying the game. I'll flash it again with the board cool and see what happens.

Two follow up questions:

1) Does it matter how many times I flash the Bios in DOS? I must've switched back and forth from the old bios to the new one a couple of times now.
2) Is there a modified Bios out there that doesn't change the profile of my card to an x850?

Well, I must of falshed my card like 15 times LOL, so I really don't think there is a limit of how many times you falsh. "BUT" if anything goes wrong, you can lose your card. So, becarful.

As for the mod bios, you can try using Rabit 1.7 or something to mod the bios yourself. See if that works. Plus is your card a GTO2 ?
