Hi, I have been using multiminer since last night, but I noticed that the miner 'plays' with my engine clock and memclock :

You can see that it goes from 1025Ghz (my settings) to as low as 300Ghz, then eventually goes back to 1025 again later. How come? It changes voltage, and hashrate aswell. Does it come from Multiminer or the miner itself? (BFGminer). I wanted to use cgminer as I know this one but is it possible to make Multiminer use it? I guess it is but I didn't find how to do it...
Sorry for my bad english.
