My board is the UD3R version
I have a dual (E8500) w/ C0 stepping
I have all of the Intel power management settings enabled in BIOS (I think there are 3 of them, EIST and some C2/C4 settings)

I could try testing with and without USB Legacy disabled but at the moment it is disabled and S3 is working. I don't know how to correct trfc but if someone explains it to me I could do it and report (I good wif the maths) EDIT: i see on some OCZ page they say set it to 54, is that what you are talking about?

I feel your pain because on my old MOBO (Asus P5W DH) I would lose the extra .5 multiplier on my CPU when it came out of S3, going from 9.5x to 9x, which obviously was unacceptable. That is one of the main reasons I upgraded to my P45-UD3

On the divider question,
I think my current mem settings are at 333 + 2.00 which with FSA @ 400+ is giving me 1:1 timings. I'll double-check that though.
