Notes
A server processor, typically deployed with Windows Server or enterprise Linux. The EPYC 9006 series is not named on Microsoft's Windows 11 24H2 or 25H2 supported-processor lists, and it launched after Windows 10 support ended. Mainstream Linux distributions run on it; a recent kernel is recommended for full Zen 6 support.
