LOL, Sorry. Didn't mean to lose you there.

Firmware is the software embedded into the video card that tells it what to do. Each manufacturer has programs that will update/change this software to newer versions.
These same programs can be used to flash an incorrect firmware to some cards (ie: One made for a faster model from the same maker) forcing them to run at the faster speeds.
This is VERY risking and can destroy the card so I don't recommend it unless you have money to burn and know a bit about computer hardware. Need I add that I do NOT do this to my own.
Others require soldering on the card itself. Never fun and always voids any warranty and can kill the card.
