The bios was push today, but servers need to be updated . fin the post Maximus XI (bios) is there. OEM (help desk) should appear soon normally take a few hours days since need to be validated and check with current Mei/chipset drivers. as far the difference is no video integrated that is it! and use adjust specs to use 127w TDP. as a variable. (updated) the KS base clock is 4.0 abd Boost Clock is 5.0 As far my concern..... same as normal 9900k
