Server-platform compatibility
SP5 server platform specifically designed and qualified for the 500 W EPYC 9965 dense-core SKU. Verify 9005-generation BIOS support, system vendor CPU list, chassis power and thermal design, SP5 cooler/carrier, ECC DDR5 QVL and population, and permitted one- or two-socket configuration before installation.
- Confirm the exact processor SKU appears on the system or motherboard manufacturer’s CPU support list, with the required BIOS/AGESA version and board revision.
- Check package/carrier, cooling and chassis air path, power delivery, memory QVL and channel population, firmware, and permitted socket configuration. Shared socket names do not establish generation or system compatibility.
- Before handling, follow the server vendor’s service procedure and use the correct carrier, socket tool and torque sequence. Record OPN, stepping, firmware, DIMM population and thermal configuration for archival testing.

Maximum boost is a peak operating specification, not a guaranteed sustained all-core frequency. Actual operation depends on cooling, firmware, workload and the server vendor’s configured limits.
