I would like to add my 2 cents. I was hesitant to upgrade from 1.3.50 to the newest version that only supports Bfgminer. I have been monitoring the thread to check on other peoples experience. Well last night I decided to give the newest version a try. I have 3 rigs and my personal PC that have a total of 12 MSI 7950 Twin Frozr giving me about 7.5 MH. All I ever mine is scrypt. I installed Version 2.2.2 directly over the top of version 1.3.50. All of my settings were imported to the newest version and all of my cards hash at the exact same rate. Not sure if it matters or not but my scrypt setting for the card have never been in the arguments box under Advanced Backend Strategies, I have always left that blank. My settings are in the coin configuration under Miner Arguments on each coin. On fast coins I use:
-w 256 -v 1 -I 18 -g 1 -l 1 --expiry 5 --scan-time 5 --queue 0 --thread-concurrency 21712
and on slower coins I use:
-w 256 -v 1 -I 20 -g 1 -l 1 --expiry 20 --scan-time 20 --queue 0 --thread-concurrency 21712
I am very happy with the newest version and honestly would have never known that it is using Bfgminer instead of CGMiner. I do have one question though. When I go to Add/Remove columns on the Detail view of each card I cannot get the Rejected column to show up even though it is checked. Is this a known issue?
