I understand that you are looking for a specific motherboard that can increase the BCLK of the processor.
Since this is the case we cannot recommend any as we do not know which motherboards could assist you with the overclocking. The unit itself is not "unlocked" so I cannot guarantee that you will be able to overclock the unit how you are intending to do.
Aside from that, Intel ® does not recommend any kind of overclocking since the processor are designed to work as per specifications and not higher or lower which can actually reduce the life time.
