Yes, this card has 256mbs DDR Memory & 128 bit bandwith.
I've tried to flash this card without any success, (Tried a bunch of 9600Pro's) and yes it's basically the same as the 9600 Pro but down clocked...If you read my post then you would have read that I use the Softmod Driver 6.7 (This unlocks it by itself) and I use ATiTool and this also unlocks it!
Version .024 ATiTool also has the option of removing the Clock lock at runtime in miscellaneous settings...Anyways, with what I got (for free) I'm very please...
Btw, the MAX levels for the card are higher, but I wanted the -10Mhz for a stability buffer.
Core:474Mhz
Mem:250Mhz
