MSI TF 3 7970s 580-740 KH/s
-
This has been a long journey but finally an exciting one. I had switched over from 2x 460s running cuda miner to 1x msi tf 3 7970 about 2 months ago right after the card was launched. I nuked my nvidia drivers and installed 13.4 catalyst and booted up cgminer. Things started slowly at about 580 kh/s and then I read the guide a few days later. Using the guide and some tweaking I managed to hit 680 KH/s and I got stuck there. I bought a second card and began playing again … but no luck I could not get above 680 KH/s.
Since then I have tried many people’s setting and none seem to work. Last night I finally found one that brought me to 705 on each card … SWEET! I felt inspired and began tinkering with all of my settings doing small adjustments. I watched the hash rate slowly climb all night. I played with every setting imaginable and finally hit 740 KH/s on each of my 7970s. Ill post my real settings when I get home tomorrow night but they were something like this. 4 threads, -w 1024, thread concurrency at 21105, and 1045/1500 clocks.
