Good to know

The C9X299-PGF-L supports non-ECC DDR4 UDIMMs, with a maximum capacity of 128GB. Overclocking memory up to 4000MHz is possible, but actual speeds depend on CPU and memory module capabilities. The board includes a robust power delivery design suitable for high-core-count processors. Note that Kaby Lake-X CPUs have different memory and PCIe lane limitations compared to Skylake-X and Cascade Lake-X.
