Thanks for the replies. On the other thread the guy could set the turbo speeds still in the bios I think whereas mine won't go above 35 no matter what other settings I choose.

I can't understand why also the onboard graphics settings have all vanished from the bios and if i try and boot without a discreet graphics card I get a red light above PCIx slot and it refuses to believe it has onboard graphics even with a bios reset and flash (just tried 1050)

I put the old bios back on and the megaraid did come back but none of the other issues were resolved

Is there some way to completely reset the board?
