msi firmware 7885vN9 is causing problems on the x99 platform for some users.
i have the x99 sli krait with an e5 2650 v4 xeon with gskill 16 gb ddr4 3200 and had to go back to N8 firmware just to get the latest W10 updates.
the 7885vN9 firmware caused all sorts of problems like no xmp. when trying to load oc profiles immediately the board would crash if you tried to save settings and reboot it would lock up ect.
after flashing back to 7885vN8 all my problems went away.
