X800 Pro VIVO to XT PE Bios Mod

I still believe, that if you don't get the pipes after connecting them and flashing them, you stand no chance of getting them at all. I have seen numorous people do the mod to the PCI-E cards and only very few have succeeded. And the ones who did succeed, some had defective pipes, so they couldn't keep them. Sometimes you need to find a point where you just stop, before you wreck your card for good, and have none at all.

Unfortunately you will not be able to unlock the pipes because you haven't xxxxfxxx in 990 register. :( You got xxxxexxx but not f in 5-th position. Looking 994 probably you haven't laser cut on the core. Am I right?

About pictures YES I do want them. (Back side can be very interesting because there are a lot resistors near core with posibility to be soldered on two places.) I am looking on my X800XT PE AGP and will try to make some resurch on this. After that I will post the results of course. ;) If you can also find from somewhere pictures of the back / front side of the same card but with 16 pipes it will be very usefull. :)

I do believe that the secret is hiden not in the core (laser cut is just additional locking method) but on the PCB. Please in connection with this see what is the Part Number of your PCB (left front side near fan connector, if should be something like: PN 109-Axxxxx-xx).
(Who knows maybe I can find something that slips out of the other people :cool: )

Thanks in advance for the support.
 
Please all the owners of X800PRO's (doesn't matter VIVO or not) and XT's to chech the resistor configuration on the back side of the PCB on the right side of the cooler holding-plate. There are 7 resistors (R339, 340, 337, 338, 341, 342, 576, 577, 580, 581, 582, 583, 578, 579) which have the following configuration on X800XT:

x=resistor, 1234567 - position number, - no resistor

1234567 R579
xx--x--
1234567
--xx-xx
1234567 R578

But on X800PRO I could see something else (it is posible to make mistake because of the picture that's why I want to check by your eyes.)

1234567 R579
xx-xx--
1234567
--x--xx
1234567 R578

I will attach the PRO picture with the checking area marked. Also I consider that it could be the key for unlocking the damn pipes :mad: .

Thanks to all for the support :)

Dil you are one lucky guy. After the last post to you and long night I solve the problem with the pipes unlocking. I will tell you what should be done with your card to unlock the pipes. Please send me the pictures of it and be patient few hours :D . Also I will need info about your core. Do it have laser cut?
 
yes it does have a lazer cut on it and i will send the pic's to you, hopefully by tonight

^I agree....I am one of the people who tired the mod....it didnt work...so I sent the card back and forked out a little more for the XT.
 
problem

please help.
i ve tryed this mod: x800pro to x800pe. i have vivo version: i ve updated bios, windows recognize card like platinum, core and memory 520/560, but there are still 12pipelines. what i ve done wrong?

djbbenn dolf sane: it looks like i will be taking that advice. so much i could do to it before it would stop working thank you guys for helping me out.
 
Well, thanks to this forum I've turned my Club3d X800Pro VIVO into a fully fledged X800xt pe! complete with 16 pipes.
I also upgraded the cooler to a ATI arctic silencer 4 rev2
Here's the results:
Clock speed 520
Mem speed 560
Idle temp 40-42
Maximum temp under full load 62

Thanks everyone for your help.

Have you used the modified flashrom ?

Worked great!

I followed the instructions in this guide to the letter and successfully unlocked all 16 pipelines on my ATI Radeon X850 Pro VIVO. I just wanted to thank the author of this thread for this nice FREE performance gain! :)
 
I purchased the Xtasy X800 XT last fall, (almost a year ago now and paid $492.50 del) I have upon occasion OC'ed the card to PE speeds, but I have not left it with that OC all the time. I decided on flashing the bios to a X800 XT PE bios and see if this works. The Xtasy X800 XT is the only bios listed under VisionTek brand. Since I already have this card, that would not help me at all. So I began looking for a X800XT PE bios that matches exactly in size and the X800 XT bios in my card. I found a match, under ATI's line of cards. I downloaded all the necessary files and made the floppy. I saved a copy of the old bios to the floppy. The first time I attempted to flash to the PE bios, I did get an error about the card ID was different than for the ATI bios. After studing about this for a few minutes. I did not see any problem in using the ATI bios. I flashed the bios again using the /f switch added to the command line. WALA the flash went perfect, all verification passed without a hitch. The card had to install the drivers all over again, when finished, it is ID'ed on the screen as IDE X800 XT Platinum Edition, this is for the primary and secondary both. I have played HL2 and MaxPayne2 last night for a couple hours without any serious problems. The only problem I have encountered is if I select restart from the desktop. The system will not restart, I have to turn off the power and then turn back on, then the system starts perfectly. If you can give me good info about that, please do.
ATI Tool shows the fan on the GPU running at 100% and the temp is steady at 41c. GOOD

I didn't think you could, that link makes no sense in the persons cpu either, they have a 2700MHz Athlon with a 201fsb...that doesn't work. Theres not even one thats stock at 2700. Plus I'd think his score would be way higher than it is. With my pro running 12p, and my Athlon at 2400 stock, and 512mb of ram I get a better score than him. It could be a PCI-E card flashed to a XT, cause sometimes they show up as GT's for some reason or another. Just my thoughts on this. :rolleyes:

ok.. I'm new in this

all i know is OC ...
but i know nothting in pipes opening...
so exept OC i can't improve my card ?

thanks :)
 
Opening pipes is the best performance increase for such a simple task (sometimes). But overclocking will always help, and can give a big performance increase aswell. Depends on how much you overclock. ;)

-Dan
 
Nice bobyjo, now yours makes sense, but the other one has a 200fsb yet the cpu is running 2700MHz. :confused:

Amen Bro

...i'm gonna do the mod....was looking for a suggestion on the bios...and about the Heat issue....why should there be an issue if the same type of cooling is used on the x800xt pe ?
Click to expand...
I got the same card, flashed it to the Asus X800XT PE bios (edited with RaBIT to 500/500).

It runs XT PE speeds flawlessly but the card ran too hot for my tastes, so I'm leaving it at XT speeds by default.

Regarding your heat issue question, it's because not all cores are created equal. Some do XT PE speeds effortlessly (and are branded as XT PE's), some run slower (thus are branded XT's), and some have defective pipelines (disabled and then sold as X800Pros).
 
What temp did your card run at PE speeds?
I have flashed mine to PE and if I leave it at 520/560 my card core runs at 41-42c.

This is only about 81f.
I don't feel this is too warm. IMO::
