[REQUEST] Unlocked CPU Multiplier for Supermicro X8DTN+

[Osku]

HI,
I know this board isn´t disigned for overclocking but i want to squeeze out some performance of the 2 X5670 I have in there.
Is it possible to unlock the Multiplier in the bios? The cpus have an unlocked Multiplier but the Motherboard seems to block me going over X22 (Default)

Im currently using this Bios : https://www.supermicro.com/about/policie...temID=7247 (Attatched)

Thanks for the help
