I'm still trying to get a little more stability from the 2 Mining Rigs I have running.
Here is a graph from one of the pools. My coins per day seem to change quite a bit.
Part of that is the "luck" of the pool I guess.
The dropouts were from overheating, I wrote a script that shuts down CGMiner when
any one of the cards gets to 86C. I don't use the auto-fan cause it seems to lower
the hash rate a little. It was about 90F here for the last couple days so they
ran hotter than normal. Usuall they run in the mid 60s - low 70s. One card not on a riser
runs in the mid 70s normally. 5 cards total, all 7970s. 4 Gigabyte and 1 XFX.
Hash rate from CGMiner total is: 3450Khs.

Just wondering what other peoples graphs look like.
