X800 GTO² to X850 XT BIOS Mod

grunge said:
.......the blue pcb one has indeed got the R430 and only 12 pipelines as standard (it's a x800xl with the gto2 bios) and has the mfr# 21067-00-20. with 1 VGA & 1 DVI output

The red pcb GTO2 with power supply & R480 core is the real deal with 16 pipelines from the off has mfr# 21067-00-21 dual DVI and VIVO.......

Can this be checked on the box or only on the cards themself, thanks......nm you can see the cards in the sapphire boxes, they got the see through window right?

Use ATI Tool to override fan settings and load @ startup via registry key.....sorted!

Flashing the GTO2 sometimes affects the fan control setup on the graphics card, fan control via ATITool doesn't work after this.

The answer is to use a custom modded bios, which will show up as an x850xt pe, have whatever clock speeds you want, and most importantly won't screw up the fan control.

I know your only trying to help out, but try to be patient with people. What i mean is the "......sorted!" part might not go down to well ;)

There isn't a window on the box, there's a computer printed label on mine with the mfr number, part number etc.

mfr# 21067-00-21 is what you need to look for on the label, these are the R480 core GTO2's.
 
Saphire X800GTO 256 AGP

I ordered a saphire x800gto 256 AGP can i do that mod on a AGP card?

and it said it was a gto2

thanks
 
To my knowledge, there is no AGP version of the gto2, it's a gto wrongly labeled.

Anyway, once you get it, open ATITool and show us your fuse data to be sure.

I've noticed there have been quite a few of those recently that have been moddable to 16 pipelines. You might be lucky and get one of those. :)
 
hey shadowflare,

I just got my x800gto2 through. I havn't tried it yet, since the power connector was missing.

Have you got a modified bios that reads as an x850 without screwing up the fan control? I think i saw one posted, but i can't be bothered to read through 163pages!! :D

I'm putting my ATI silencer on it, so i expect it to be able to handle x850xt pe speeds. I'm going to volt-mod it as soon as i have the time as well. Can't wait to see how it performs!! my samsung 2.0 used to do 610mhz, so i wander how far the 1.6 will go!

Thanks :)

Which X800 GTO2 is it? If it is the one with dual-DVI, then I don't have a bios file for that. I guess I haven't downloaded one from anyone for that yet. The only bios files I have are for the ones from before they released the dual-DVI + VIVO version.

So what is it you want exactly? Do you want it saying it is a X850 XT or X850 XT PE? If so, I could do the mod for you if you want me to. :)
 
I think it's the one with VGA/DVI, and no VIVO.

I'll be home in a few more days, so i'll see what clocks it can do. Hopefully it will be able to handle xtpe clocks.

Thanks :)

Here's the bios that I currently use for my VGA/DVI, no VIVO R480 GTO2; I'm attaching it to this message. It is modded to 16 pipelines and with the X850 XT PE name. No modified clocks or anything else besides the pipelines and name. I've been using this one for quite a while now with absolutely no problems. BTW, this is from the retail boxed GTO2.

Oh cool, thanks :)

I'm gonna compare the x800gto2 ram timings to the x850xtpe timings, and have a play around with those in RaBit.

Also, on my gto2, there's a small block with two switches, covered in tape. Do you know what that is? It's begging to be fiddled with! :p

Thanks again! :toast:

Have seen them before but can't find any one who will tell what they do. I want to fiddle too!;)
 
??sapphire GTO² can not be modded??

I am rather hopeless. I had tried tried to free the 16 Pipelines but atitool and other software reports that it is still 12 Pipelines. Using AtiTool the board hast to be moddable (s. atached jpg-file). I had done the flash as well with flashrom and atiflash using the Bios from http://www.techpowerup.com/articles...P.Samsung16.bin. Also I have try it with the Catalyt and the Omega driver. But no chance to open the 16 Pipelines. Also the 3DMark-Benchmark do not increase.

As a diagnostic I made a report with the tool of the Omega driver as well with the original and the new bios. These reports are in the atached pdf-document. The differences are marked up in red. I have no idea anymore :banghead: I hope that a specialist in this forum can help me. Thanks a lot!!

What did you do to flash the bios exactly? According to the picture you posted, you can get 16 pipelines, but your bios is still set at 12 pipelines. You must not have flashed the bios properly, since those fuses show that the bios is still blocking out 4 pipelines. (CONFIG_ROM_FUSES)
 
Try using atiflash. It's always worked great for me.

Once you have that, and the new bios on the floppy, reboot, and use this command line:

atiflash -p -f -newbios 0 [bios name].bin (zero, not o)

You're probably didn't add the -newbios tag. Without that, some of the settings from the original bios will not be overwriten.

Good luck

Thanks a lot. You are right; i do not use the parameter -newbios. I do it exactly in that way written in the instruction (http://www.techpowerup.com/articles//overclocking/vidcard/34/8). There is no "-newbios" parameter. Is this a new parameter of atiflash/flashrom?? I will try it tomorrow and will report what happens.

What kind of graphic driver do you prefer? The ATI-Catalyt or the omega driver?
 
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 ;)
 
agp card

ok there is alot of threads about flashing the bios i just want to make sure i dont mess up a video card i just bought its AGP ati saphire x800gto and here is a photo can i still bios mod it if its agp?

ps trying to post pic hope this works

Yep, the fuse data indicates that you can flash a bios to unlock the last quad.

When you flash, i recommend using atiflash, and make sure you use this command line:

atiflash -p -f -newbios 0 [biosname].bin

good luck
 
flashed

I flashed just like you had it not your falt now my card does not start up does that mean
i need a pci video card to fix it used atiflash -p -f 0 modbios16.bin could i have done somthing elts wrong or is it because its agp?

thanks brad
