Subject: XMP issue I think

What is the exact, full model number of your memory?
I can't tell from your first post if you have 4 x 4GB DIMMs, or 2 x 8GB DIMMs.
Is all 16GB from one kit of memory, or from two kits, etc?
We need to check your memory for compatibility, and hopefully not a mix of multiple kits. That is not always an issue, depending upon the manufacture. Given the DRAM voltage I see with the XMP profile enabled, you might have Crucial memory.
If you have 2 x 8GB DIMMs, they should be put in the A1 and B1 memory slots.
In the UEFI, DRAM Configuration screen, all the way on the last page of that screen, find the MRC Fast Boot option. Set it to Disabled, which will enable Memory Training. That helps with higher speed memory.
Your board does not seem to have a VCCIO voltage option. That is not critical. You can increase VCCSA from its Auto value, but I've found you don't need 1.20V for the VCCSA with even higher speed memory. Try 1.15V, and if you get 2800 to boot and is stable, you can slowly reduce it from there.
You can try disabling the XMP profile, set the memory speed manually, and have all the other memory options set to Auto (except MRC Fast Boot.) Set the DRAM voltage to 1.30V, since the XMP profile seems to set it to 1.25V.
Using the manual memory configuration method above, try increasing memory speed in steps. Try 2400, 2600, or 2666 before 2800.
Hint: If you want to post pictures of your UEFI screens, put a USB flash drive in a USB port on the board's IO panel. When you are in the UEFI on a screen, press the F12 function key, and the current image on your monitor will be written to the USB flash drive. You can look at those pictures, or use them in a forum post.
