FAQs

Q: How does the EPYC 7551 compare to the 7551P?
A: The 7551 supports dual-socket (1P/2P) platforms, while the 7551P is single-socket (1P-only). Performance per socket is similar; choose based on platform topology.

Q: Is this CPU drop-in compatible with all SP3 boards?
A: Physical socket is SP3, but BIOS/microcode must explicitly support the EPYC 7551. Consult your server vendor’s CPU support list.

Q: What memory speeds are supported?
A: Up to DDR4-2666. Actual operating speed depends on DIMM type, rank, and population.

Q: Does it support virtualization and encryption features?
A: Yes, AMD-V and IOMMU are supported, along with SME/SEV for memory and VM encryption on capable platforms.

Q: Can different EPYC 7001 models be mixed in a dual-socket system?
A: Mixing is generally not recommended. Use matching CPUs (model/stepping) for stability and performance.
