Hi guys, my i5 4460 is getting old so i thought trying to oc it a little bit from 3.4 to like 3.8 or if It can 4ghz. So i found that back in the days there were a lot H81 with a Z option which enable the cpu oc. Then this option was removed, so people had to roll back their mobo bios to have the feature back . Now i have an H81M VG4 r3.0, apparently there were 3 version of this mobo the r1.0 then It came the r2.0 and then mine . People with the first and second version had only to flash an old bios from the bios support page of their mobo to get the oc feature back, but as u can see from here(https://www.asrock.com/mb/Intel/H81M-VG4 R3.0/#BIOS ) the version r3.0 of this mobo has only 1 bios on its bios support page. So the question is can i flash my H81M VG4 r3.0 with an H81M VG4 r2.0 bios?
