Gigabyte GA-EX58A-UDXX Release date?

[nyeah]

Ok i tried b2b at 4 and am just now getting back to desktop. I'm at stock settings now. For some reason, even after clearing cmos, no OC works. No post, then OC failed screen, no matter what settings. Also now only 8gb of ram are usable. Post screen shows 8gb and windows shows 12 installed 8 usable. remind me to not touch the b2b settings again lol.

same happen with mine, iuse F2 BIOS and i can't oc at all, even can't change cpu multiplier.
if i do that the result will be no post and psu led will indicating that something is shorted, don't know why, i hope RMA/BIOS update will solve the problem.
