Jonspd, IIRC your stepping was close to mine (although mine is not a BE)....

These settings folded so long I started worrying about my electric bill and turned it off (the Carbon Footprint thing, ya know.. )

It ran for 4+ days and it never stuttered, it's still my everyday setting...
I didn't pay close attention, but the WU's were clicking off in well under a 24 hours....




I really wish someone with an "074# MPMW" that was just looking for stability would try these settings... At least for me, these seem to be pretty well tweaked... I call it 2.5.. hehe...
