after all the sata port on the board and still hitting the 220 barrier (regardless of memory to cpu mutliplier) i am wondering if the board was shipped with ht at 5 (as it is avialable with nforce3) since we cant see it in the bios it is possible and as 220 would break 1100mhz for ht, it could explain some of the errors. Though it could also be something else entirely.
