i9 12900K Compatibility Problems With DDR5?

Has this been fixed yet? I sure would like to be able to use my DDR5 Ram at its rated speed of 4800MHz.

Hello VictoryPete,

Thank you for posting on the Intel️® communities.

Regarding your question, there is no compatibility issue with the i9 12900K running DDR5 at 4800MHz, as this speed is listed on the CPU specifications. https://ark.intel.com/content/www/us/en/ark/products/134599/intel-core-i912900k-processor-30m-cache-up-to-5-20-ghz.html

To achieve the targeted memory speed on Intel® 600 Series Chipsets, you should try the following recommendations: https://www.intel.com/content/www/us/en/support/articles/000088926/processors.html

Use two identical dual-inline 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 (see bottom left image).
When mixed DIMMs are populated, the memory speed may be lower than the target or the system may not boot.
Populating with a single DIMM per channel for either 1-DIMM per channel (1DPC) designed board or 2DPC designed board produces no memory speed impact.

Best regards,
