Recently, I just attempt to flash my Sappphire 9550 bios with a 9600NP one. I stumbled upon the bios that this site provides and I tried one by one to see if they are compatible. It seems that only the Gigabyte 9600NP bios suit my card. Thought I have done a good job out of that until I realise that my mem bandwidth shrunk from 128 bit to 64 bit. Not sure if it is the problem with the Gigabyte bios. I attempt to flash the old bios back, but the mem bandwidth is still the same at 64bit. Is there anything I can do to revert it back to 128bit? Will tweaking the bios help? Or is there anyway to empty out my bios and reflash again? Hope someone here can help. Thanks in advance.
