You don't need rivatuner for this kind of modding/flashing. It is recommended that you use the ATI X850 Pro AGP from ATI itself which has VIVO also, there seem to be alot of people who uses this card and are successfully flash to XT/PE with 16 Pipes.
Before you begin: THIS MOD/FLASH IS FOR AGP VERSION ONLY!!!
Here are the steps on how to do it
1: Download the XT-PE BIOS, and the Modified flashrom (check the attachment)
2: Make a backup of your current BIOS with modified flashrom.
3: Flash your AGP X850Pro with XT-PE BIOS with modified flashrom.
Commands:
To save your bios type this: "flashrom -s 0 backup.bin" (your original bios will now labeled "backup" and the extension is "bin"
To flash the bios type this: "flashrom -f -p 0 (bios name).bin"
Notes: I rename the XTPE's bios to PE so it would be easier for me or even you to remember and to flash.
To back up type this : "flashrom -s 0 backup.bin"
To flash type this : "flashrom -f -p 0 PE.bin"
Cautions: It is recommended that you downclock it to the Pro's original 500/500 or 520/540 for XT. But DO NOT leave it at PE speed without aftermarket cooling.
I hope that all you will be able to unlock it like i did and enjoy your 16 pipes card
Here is the ATI X850Pro AGP Vivo Card that i used to flash
http://www.bestbuy.com/site/olspage....=1118842670249
Thus far we (us ATI modders and Sphere of course) have only seen the agp vivo versions unlock but all other pros should still be able to flash to a 12 pipe xtpe.
Although, it should works on the ATI VIVO card, i have no guarantee that it will turn out like we wanted, so don't put your bet on it and if it turns out that you can't unlock the 16 pipes, it will hurts you really bad, and me too (cause you'll witch (replace the "w" with "b") and moan about it to me.
You could always get any other brand X850Pro that has VIVO, examples are Sapphire, MSI. ect....
Edit: Another thing, you can unlock your Pro to get 16 pipes after you flashed to XTPE, then if you really want it, you can always use your original bios to flash it back (it will stay 16 pipes) to get CONTROL OF YOUR FAN!!!
The XT and PE bios disable your ability to control your fan, all i know so far is that the Pro has that ability to leave you with that function.
Use the ATIflash provided in this attachment to flash it back to PRO and have the fan controller.
Edit: You can also re-flash to XTPE with the modified flashrom to get the XTPE name and THE CONTROL OF YOUR FAN TOO!!! I tried it and it worked, Now I was able to get both the XTPE bios with the Fan Controller
If you have any question please send me a PM or Sphere.
EDIT: I added the bios "X850XTPE with Fan Controller" as a shortcut to you guys, so just use the modified flashrom and that bios then you're done, you will get both 16 pipes 540/590 speeds and fan controller
