Z170 OC Formula XMP Switch Not Working

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   Whenever I flip the XMP switch to the "on" position on my motherboard, the UEFI/BIOS/Windows won't load. The screen will remain black, despite the computer powering on.

For troubleshooting I've:

Re-seated the memory in the appropriate slots DDR4_A2 and DDR4_B2 as instrurcted by the user's manual. I've turned the XMP switch off and booted to UEFI and confirmed that the BIOS is showing that there are 2 16GB sticks appearing (which there are). I've upgraded to UEFI version 1.90 which is the latest available.

Is there any way to get XMP working with this setup, or can this memory only be configured manually inside of OC Tweaker? The RAM I purchased was on the approved memory list for this motherboard and has been reviewed well by several sites, and as long as I keep XMP turned off, it boots without a problem.

Also, is the XMP settings something I should configure first in the UEFI settings, Save and Quit, then power off the machine, then flip the XMP switch to the "on" position? Thank you!
