Please also note that our DRAM kits are only validated an guaranteed to work in the configuration that they are packaged and sold as.
Considering that we do not currently have any 4-module DDR5 memory kits for sale this would indicate that you are mixing two separate kits in order to populate all four DIMM slots. Mixing memory kits such as you are doing can so can lead to system stability issues, prevent XMP from working, or even prevent the system from booting entirely.
When you consider the limitations of the integrated memory controller on the 12-gen Intel CPUs, and that you are using two memory kits in an unsupported configuration, you are indeed likely to have issues when attempting to not only enable XMP, but you could potentially have system stability issues with BIOS settings at their default settings.
Sticking to a single 2-module memory kit is going to net you the best possible ability to hit the rated memory speeds, and provide you the better system stability.
