Did Asrock 775 Twins HDTV support SATA2?

ive been tryin to hit 4ghz for months now with no luck... its starting to look like my MOBO cant handle the speed.... so i A) either need to buy a new mobo, or B) wait to just upgrade whole system...

what was your vcore when you went to 4ghz and what deviders and ram timings were you using?

i use auto in memory timing , but in nb and memory voltage i use high

my sistem oc (3,6Ghz) running well n stabil
in 3,8 Ghz cannot work well

oh i oc memory clock too ( run in DDRII 667Mhz)

but my memory is standar (twinmos pc4300) ,... how about buy new corsair 667 ...(i hope can reach 4Ghz at my cpu)
