Hello! You're experiencing issues with your PC running two DDR5 16GB sticks at 6400MHz, but after adding more sticks you can't get the XMP profile to work. The BIOS is up-to-date, and lower speeds also fail. Your current setup includes MSI MAG Z790, Intel Core i7, and a 4x16GB CL36 RAM configuration. You're looking for a solution to enable 6400MHz across all four sticks.

It's definitely a challenging setup, particularly if your hardware components aren't uniform.

They seem to be the same.

Ensure it runs slower. 6400 is too fast for two sticks. Four is much more demanding on CPU memory controller.

Ensure you're using the most recent BIOS update. Those Micron components from the 24Gb Rev. B memory ICs in the DIMMs can be quite unstable, making it difficult to run and train effectively. It's advisable to use a board with a BIOS version that specifically supports them to avoid major issues when trying to achieve higher frequencies. Ideally, return the device and upgrade to the CL32 model, which is Hynix-based and includes more BIOS optimizations. In the best case, consider replacing it with a 2x32GB unit, as these are generally more reliable to get working.
