Server-platform compatibility
Single-socket SP3 servers designed and validated for first-generation EPYC 7000 processors. Use a Naples-capable board/firmware, 180 W-rated cooling and power delivery, and populate all eight memory channels with supported ECC registered DIMMs.
- 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.
