Hello VictoryPete,

Thank you for posting on the Intel® communities.

I would like to know if you are having any specific memory issues with your Intel® Core™ i9-12900K Processor in order to provide a more accurate assistance.

In the meantime, here are some recommendations for DDR5/DDR4 memory module installation:

Use two identical dual-in line memory module (DIMM) part numbers on 2-DIMM per channel (2DPC) to achieve Intel® Core™ 12th Generation targeted memory speed.
The targeted memory speed is not guaranteed when DIMMs of different part numbers are connected within the same channel.
When mixed DIMMs are populated, the memory speed may be lower than target or the system may not boot.
Populating with a single DIMM per channel for either 1-DIMM per channel (1DPC) designed board and 2DPC designed board produces no memory speed impact.
This applies to DDR5 and DDR4 memory modules / DIMMs.

I look forward to hearing from you.

Regards,

Steven G.
