PhoenixMiner, I want to ask you to improve monitoring log.
I have 9 cards installed and sometimes it is not convenient to catch the situation when hashrate of one of them becomes 0 MH/s. Please, use red color for marking abnormal hashrates - it will make more simple to see the problem.
The other problem is log. After miner fails my PC reboots (watchdog). To find the problem card I need to open log and find the text with problems (zero hashrate or "not responding" messages). But sometimes log file does not contain useful info, because it stops earlier than problem occur. I mean the problem appears in the miner window, but it does not appear in log file because of log file update delay (PC reboot earlier).
This will be useful during batch undervolting/overclocking to find which card to change settings.
