Well I got my new board after the RMA and it is rock solid stable. SLI is also rock solid stable now. I have been testing for two days before posting this to be absolutely sure.

It seems some of these boards may just not be very good from the factory.

However one thing I noticed about this new board: very high MCP temps reported after 2+ hours of SLI Crysis.

Is 82C too hot?

Also my understanding is that MCP = SB, is this right?

I dont know how I am going to put a fan over the SB with these two huge cards in SLI.

Any thoughts?
