I wish it was that simple. Basically, the main difference between GTO and XL is 4 pipelines. Minor difference is core/memory speed. Now, you need to figure out how to unlock the extra 4 pipelines. Sometimes it works, sometimes it doesn't. It depends on the manufacturer. Here are the instructions. Tedious, but it pays off. If this doesn't work, then search for "unlocking pipelines on x800". You will see some variations to the following instructions.

Download and install ATItool: http://www.techpowerup.com/atitool/

Click the settings button and choose overclocking in the drop-down menu.

Scroll down until you can see the CONFIG_DIE_FUSES and CONFIG_SUBSTRATE_FUSES.

Verify that your card can be unlocked by checking for an ‘F’ in the indicated positions of the hexadecimal each number. The capital X represents any hexadecimal number (0-9 or A-F).

CONFIG_DIE_FUSES 0xXXXXFXXX
(the fifth character after the little x must be an 'F')

CONFIG_SUBSTRATE_FUSES 0xXXXXXXXF
(the last character must be an 'F')

If ATItool reads an ‘F’ in the indicated spots, you should be able to unlock your card. If not, I am afraid you are out of luck.

Now select miscellaneous in the drop-down menu.

Click the button that says “Save VGA Bios to file...”. Give the file a simple name like “12pipe.bin”. This will be your backup copy.

Make a second copy, which will be modified, and name it something like “16pipe.bin”.

Download the hex editor from this website (I would recommend using the “stable” version instead of the beta version): http://www.mh-nexus.de/programs.htm#HxD
This software will allow you to modify your bios to enable the pipelines.

Extract the hex editor program and run it. Open “16pipe.bin”.

Find the row marked 00000070 and the column labeled ‘A’. You should find ‘61’ at that location. The second bit represents the number of disabled pixel pipe quads. Change the data value to ‘60’ to enable all 16 pixel pipes.

Note: If you ever get bord later you can mess around with disabling pipes. 1 means four pipes are disabled (X800GTO), 2 means eight pipes are disabled (X800GT), 3 means twelve pipes are disabled (yep only 4 left active).

Save the modified bios and exit the hex editor.

I recommend using ATIflash.
You can download it at the bottom of this page: http://www.techpowerup.com/bios/

This webpage has pretty good instructions on how to flash your bios:

If you follow my naming conventions, the DOS command line input should be: atiflash.exe -f -p 0 16pipe.bin
