Hi I was just wondering when ATI/AMD is going to upgrade their drivers to be able to do more than two gpu crossfire in linux as I have three gpu chained already but it only enables two of my cards. My system is:
Phoronix Test Suite v3.6.1
Processor: AMD Phenom II X6 1055T @ 2.80GHz (6 Cores), Motherboard: Gigabyte GA-890FXA-UD5, Chipset: ATI RD890 PCI-e GFX Hydra part, Memory: 16384MB, Disk: 1000GB Seagate ST31000520AS + 1000GB FA GoFlex Desk, Graphics: 2 x ATI Radeon HD 5670 1024MB CrossFire (775/1000MHz), Audio: Realtek ALC889, Monitor: FUNAI TV, Network: Realtek RTL8111/8168B
As you can see Phoronix shows just two of my cards are crossfire enabled.
