I can see that this board does not have an option to turn on TPM in BIOS, but you can “Allow BitLocker without a compatible TPM” in W8 control Paenl, and this way use Bitlocker anyway.
However, does this affect the performance of BitLocker compared to a TPM enabled device?
Intel® NUC Kit 5i5RYH provides with BitLocker technology; however, it will request a USB drive to save your settings. TPM technology is not available on this model. Only the Intel® NUC Kit NUC5i5MYHE has TPM.
