No idea is this is new build or existing working sysem with new RAM.
Regardless, start by resetting the BIOS to Optimal Defaults and start from there.
Why not quit trying the XMP for now and try setting the specs manually.
Start with 1066 @ 8-8-8-19 then test.
Go to 1333 @ 9-9-9-24 and test
Move to 1600 still @ 9's and test, then drop the timings.
Set it to 1.65V manually, seems unlikely anything but 1.5V would be the true default.
