its the 1205 bios , and it runs like a charm , the bios clearly states sli and not plus , yet everest shows that the chipset is the hybrid i650 one , and not the i680.
my memory problems are fixed , now i can run 4gb of ram 4X1 .
and the system is supper stable 28H of prime.

maybe thay discoverd that the i680 bios works better?

yet im having problems OCing tho , i can get windows to boot on 3.0ghz (q6600)
when on the old bios i booted 3.0 with no problem , all set at auto .
