I have been mining scrypt with my Sapphire 7950 Vapor-X on Win 7 until the whole system seemed so laggy. Even a reboot took too long, finding nothing else wrong I just formatted and reinstalled Win 7 and all the drivers etc. Now running the very same script that got me ~635 KH/s is getting me ~520-540 KH/s. Here is the bat file
c:
cd\
cd cgminer-3.4.3-windows
setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_USE_SYNC_OBJECTS 1
cgminer --scrypt -o stratum+tcp://pool1.us.multipool.us:7777 --gpu-threads 1 --gpu-engine 1045 --gpu-memclock 1455 --thread-concurrency 16384 -u coldbreeze16.1 -p x -w 256 --lookup-gap 2 -I 20 --gpu-vddc 1.125
Btw GPU vddc switch never worked, I have to set it in Trixxx on each startup. Undervolting to 1.131 V (from 1.25V). I was worrying if something could be fried? Or is it just a software thing?
