Installed 1.5b7 and all is well. I haven't played with addl. OC yet but my board temps are fine, for some reason I ran warmer with 1.5b3-5. So I guess a good report is I notice nothing as of yet the way I am set, but that's a good thing, right. I Bios OC only, but I might have to set basic and see how the OC dial works now and to (for fun) try max FSB again. I never got a steady stable auto FSB/Max when I played with it.
