Did you Try MCH reference lower, like .64(50% according to your 1.28 VTT)-.70v(54.7%) this seems to be the range that many have success with. For me .66 is the ticket, others like .68 or .70v. These are what ET6 reports or set them w/ CPU termination set at 1.2. You can raise the VTT after that back to your 1.28

Also on the "CPU clock drive" try 800mv, then on "PCI express clock drive" try 900mv

Also you can try CPU clock skew like 200ps
