I just installed the latest beta bios that fixes the quad multi and it works great! Haven't done much other than set fsb to 323 and multi to 11 for 3.553GHz and all cores are running the same speed according to Everest CPUID and RMClock. Sweet!

I'm going to test to see if I can get fsb above 333 later and will also see if I can get ram above 1058 - both were 'capped' at those speeds before. Probably still are, but the multi issue was my main concern and it is fixed now.
