If you don't want to install your card as a Gigabyte XT you might also backup your old bios and flash it over the Gigabyte bios;
this won't disable 16 pipes again, because flashrom doesn't overwrite everything.
Here you go:
Backup BIOS:
flashrom -s 0backup.bin
Gigabyte XT BIOS:
gvf11 -p R80X256V_filename.F1
or
gvf11 R80X256V_filename.F1 -f
Re-Flash your backup:
flashrom -p 0 backup.bin
The Gigabyte XT Bios is required to unlock pipelines, and is the ONLY thing required (and only BIOS that can do this). Nothing else has to be done.
