Ive got a Problem Running my Crossfire Setup at Dual x16.
I have Two Sapphire 4890 Toxic Cards on a ASUS Crosshair III Formula Bios latest 1403. According to ASUS the Board has 2 PCI-E x16 Slots which can run @ x16 Dual Crossfire
my other specs
AMD P2X4 965 C3
4 GB DDR3 OCZ HPC Reaper 1600MHz
3x 1 TB Samsung HDD
My OS is Windows XP Pro 64-Bit ,on the latest Catalyst 9.12
My Primary Adapter runs at Proper PCI-E 2.0 x16 According to ATI Control Center,
The Secondary Adapter only Runs at PCI-E 2.0 x4.
GPU-Z also Says Link Width is x4 but x16 capable , and i couldnt find an Option in the Driver Menues to change this.
The Mainboard Manual has a Chapter for Bios of PCI-E Watts Configuration Peer 2 Peer Link etc. but in my 1403 Bios this Option is Missing. According to ASUS Support the BUS LANEs dont need to be configured manually. ASUS mailed me a new Bios to solve this problem, but it didnt help.
I also havent found any similar option that could be relevant to this problem.
Any Ideas
