Radeon R5 330 Driver?

Okay, i made an account for this specific question, where's the R5 330 Driver? For some reason my computer thinks i have a R5 M320 (which is if you dont know a laptop graphics card) when i have a R5 330! The computer i have is a HP 550-300no that i downgraded from Win10 to Win7 so i could play 'em old games (because Win10 is a fgt and doesnt play the old games i want to play) and i have the latest Radeon Crimson thingy, any fix to this? Because i think it affects performances on some games.
