I noticed something interesting with my Mercury that I was hoping others could confirm. My miner has been running at about 120GHs with 1 core disabled pulling 117W of power at about 36C per bertmod. I stuck the miner in the Garage yesterday since it's getting cold here now and this morning I check and it's running about 138Ghs pulling 109W of power at about 27C and only 1 core disabled. I've read several posts on here from 'ormoma that the temperatures don't matter but this clearly shows that a 10C drop in ambient temperature gave me a significant boost in hashing power that has been sustained ever since the temperature change not to mention the lower power draw...
honestly, some of the problems in here are caused by too much fiddling. Example : re-flashing An Aussie Jupiter with .096 last night... seemingly slowed the rate to around 400 from 550!... BUT... slowly, gh by gh, overnight, it climbed up all the way back to 550it did this on original setup as well.
