been following Bitcoin for about 3 months. mining on one PC for about 7 days.
Just set up my first mining rig.
Windows 7 with 2 HD 6950s in Cross fire. using Gui miner.
the GuiMinder shows under Device:
[0-0]Cayman
[0-1]Cayman
[0-2]AMD Sempon(tm)140 Proce
I started 0-1 Cayman getting 295.2Mhash/s
Tryed to start 0-0 Cayman and it locked up.
Am i doing it wrong?
Edit: my CPU is at 100% with just one core. Would it help if i unlock second cpu core on mother board?
With high CPU usage is sounds like GUIminer is using a CPU core for mining.
Try running without the crossfire connector (run them as two separate, independent cards): sometime when cards are crossfire'd they will be seen as one GPU to the system, not two, depending on miner and system.
