Thanks, ArVee!
I haven't paid near enough attention to exactly what work unit I'm running each time - have been more involved with trying to get her stable.
I did some web surfing and understand more what Micro was saying about there not being a slider for the shaders. Found a screen shot of Precision rather than the Precision X. Same on Afterburner - no slider shows up for the shaders on it as well - same for Galaxy's program also.
I'm back to Precision now and am getting more comfortable with that. I'll let her run where she's at for a while and then maybe try and tweak her up 1 mgh at a time.
