I'm new throught here, but I mine for quite some time now.
I would like tos ask to everyone who uses HD7990's for mining and share your cofigs like I'm going to do, because I think that I'm not beeing able to take the maximum performance that I should from my GPU...
My is:
Brand: Porwercolor
BIOS version: 113-C3860100-X00
GPU Engine: 925mhz
GPU Memclock: 1775mhz
GPU Powertune: 20%
Voltage: 1.000v
Hashrate: 1150kh/s (575kh/s each GPU)
Power consumption: 400W
cgminer/bfgminer settings: cgminer.exe --scrypt -o stratum+tcp://pool.com:0000 -u whatever.1 -p x -I 20 -w 256
Yes, I've consulted the Litecoin mining hardware comparision, and I can't achieve nothing not even close to those values.
I would really apreciate if someone could help me on this
Best regards
Andre
