Bios just updated to most recent version
XMP Enabled

When I boot up I get;

"Memory modules were found on non-optimized memory slot"

Basically only DIMMB1 DIMMB2 are detected as RAM in Bios.

All 4 sticks are seated, checked and double checked.

Please help!

missing channel usualy means cpu is not seating properly, you might want to reseat it
