only one gpu detected? - Crossfire

[Jellepepe]

hey guys,

 

 i have a little issue, i have 2 asus 3650's (one passive one active) in my older secondary pc, and connected them with a crossfire bridge, according to the board manufacturer it supports crossfire in the first 2 slots (8x,8x) but in ctalyst controll centre (13.1, the one recommendd by amd for these older cards) only the first one is detected. so i'm unable to enable crossfire

 

any thoughts?

 

specs:

mobo: ASUS P5Q-E

Cpu: Core 2 duo E8400

Gpu's: 2x asus 3650 512 mb

some 1TB HDD and 4 gb ram

 

Oh btw, windows does detect the second card in device manager

 

Thanks in advance,

 

Pepe
