Hi,
Running 2x16GB Corsair Vengeance LPX with i9 9900K perfectly for one year now in XMP mode. I added 2 extra memory modules to get 4x32GB.Also Corsair Vengeance LPX. Now the PC won't start. After several attempts it allows me in the bios. When I change XMP (profile 1) to auto the PC boots and works perfect. The system sees the 64Gb, but the performance is terrible. Benchmarks are suddenly terrible. I've added the memory info from CPU-Z Thanks for helping out.
