first things first, the setup
MOBO: MSI 890FXA-GD65
PSU: CoolerMaster SilentPRO 850W Modular
GPU: XFX ATI Radeon HD 5770 x2 (HD-577A-ZNFC)
Catalyst: 11.11
OS: Win7 Ultimate x64
and CCC Crossfire diagnostics tells me...
"the internal bridge interconnects are not properly connected. Both bridge interconnects must be connected."
obviously this is incorrect as these cards only have a single connector. (not tri/quad-fireable) I have tried buying a new motherboard (old one was Gigabyte 790XTA-UD4), psu (old one was Corsair ModXtreme 600W) and crossfire cable (tried a few). I have the latest drivers and I have tested each part individually, everything is perfectly functional but i still cannot enable crossfire. I have tried all the usuals like reseating the cards, cleaning connectors, bios settings, drivers... I am stumped.
any ideas would be appreciated.
