Hello everyone,
Trying to configure 2 x MSI 7990 for mining rig ( not using crossfire as it is not required )
Motherboard - Asus M5 A99X EVO R2.0
DDR3 16 GB 1333
Sempron 2.8
PSU 2 x 750 Corsair
When only one card is plugged in ( does not matter which one) - no problems
but when two are connected 1 core lock itself on 500 Mhz ,150 Mhz Memory and 0.950 V without means to change it ! Other 3 cores specs are fully configurable.
Please help as I'm running out of ideas....
