Etherum with R9 390 (31MH/s) and 7970 Lighting at 25MH/s, solid enough.

That is very fast for the 7970 at 25 MHz/s. Does it have modified BIOS to reduce the memory timing? Usually it is just 23-24MH/s.

No. Clocked to 1150/1600 (Lighting)

Code:

setx GPU_FORCE_64BIT_PTR 0
setx GPU_MAX_HEAP_SIZE 100
setx GPU_USE_SYNC_OBJECTS 1
setx GPU_MAX_ALLOC_PERCENT 100
