The BIOS is even more responsive than in the past and lag is non existent, I spent a bit of time in BIOS to not be annoyed with lag and mis-clicking as a result.
The BIOS is pretty basic and void of any overclocking features with the exception to primary memory timing is adjustable. The NUC does support XMP profiles up to 2133Mhz so NUC does not benefit from faster memory speeds unless you manually adjust timing.
There is an check box option on the memory page to optimize round trip latency, Setting this option will save you about 33 seconds on SuperPi 32M and about half a second on 1M. This is a nice free performance boost if you do not have it set already.
You can increase 3D performance from the Iris graphics by manually setting the memory timing and then setting memory amount and aperture size to maximum values. Just setting memory timing alone gets you a decent boost in FPS alone.
You have the option to enable and disable all onboard devices from BIOS, you can also disable Hyper Threading and High Performance Event TImer if needed.
Oddly, you have one M.2 slot and one SATA port yet the BIOS supports RAID. I did not try to enable RAID with drives attached to both ports due to Intel does not ship the needed SATA power adapter with the NUC K units.
The BIOS shipped on my NUC was 028 and BIOS 033 was available at the time of writing this review, I checked Intel site again for a new BIOS to find version 039 was available. It seems Intel NUC BIOS teams are pumping out new versions fairly quickly. The first new option I see is "silicon debug features" in the performance tab.
BIOS 039 is definitely faster/higher performance than BIOS 033. BIOS 039 also has RTL optimization disabled by default. Reading other reviews it seems the Corsair branded DDR4 will not work with this RTL option enabled.
