I've an r9 280x for mining scrypt based coins..
I use windows 7 ultimate 64bit
color 02
setx GPU_MAX_ALLOC_PERCENT 100
C:\cgminer\cgminer.exe --scrypt -o stratum+tcp://poolurl:port -u username.workername -p password -I 13 -g 2 -w 256 --thread-concurrency 8192 --gpu-powertune 20
I get only around 670KH/s but the reported hash values is around 720 Kh/s and I see many people mining @ 800+KH/s with the same card..! How to undervolt it ?
I get some box (
