Hi raviharshil27
🙂 Qcode 8 is a problematic code in so much as it's not documented. It is however quite common and many have found it to be a Memory issue. Your Qcode sequence seems to indicate this.
Have you flashed the latest Bios yet.? Once flashed and if Bios is accessible then you will have to tweak Primary Timings and voltage to obtain your RAMs SPD.
Depending how you tested RAM. they may test OK but still be a mismatch. Check they are listed on the Rog Crosshair vii wifi QVL.
List your RAM kit Part No.?
Test with just one module in slot A2 initially then add the others and make sure they are well seated especially the offside to the clip.
If this still does not work then test the MB with another known working kit of RAM at 2666MHz (listed on the QVL and preferably (2x8) with Samsung b-Die chips.
Hopefully this provides a fix otherwise you may have to RMA the MB.
