I don't know what I'm doing wrong but each of my 7970 is only doing 500 Kh/s
Settings:
CGMiner 3.1.1
Catalyst 13.4
Undervolted to 925mv on all cards
Power Limit % at 20
Core Clock: 925mhz
Memory Clock: 685mhz
Temps: ~62C
I know that Memory Clock does affect LTC Mining but it made no
difference at 1575mhz for me (well only 10 Kh/s difference) but gave a lot more heat.
CGMiner settings:
cgminer.exe -o stratum+tcp://us.wemineltc.com:80 -u xxx.7970 -p xxx -o stratum+tcp://coinotron.com:3334 -u xxx.pcs.7970s -p xxx --thread-concurrency 8192 -I 13 -g 2 -w 256 --shaders 2048 --scrypt
Any help would be appreciated!
do you use Powercolor PCS 7970 ?
Try these settings
first of all,you should use ccc 13.1 instead of 13.4
Cgminer 2.11.4
then set your core/mem around 1050/1250 (with this core/mem i set voltage at 1.063 in MSI afterburner)
if you didnt use Powercolor PCS,you should flash giga 7950 F42 bios
and cgminer setting is : --thread-concurrency 8192 -I 13 -g 2 --scrypt
here my result
the weather is so hot now
