FAQs

Q: What does the P in 7551P mean?
A: It indicates a single-socket–only part. The CPU can be used only in 1P SP3 servers and cannot operate in dual-socket configurations.

Q: Will it work in any SP3 motherboard?
A: It requires SP3 socket and BIOS support for the 7551P model. Check the server vendor’s CPU compatibility list.

Q: Is performance similar to the 7551 in single-socket?
A: Yes, per-socket performance characteristics are similar; the key difference is platform topology (1P-only vs 1P/2P).

Q: What memory configuration is supported?
A: ECC RDIMM/LRDIMM DDR4 up to 2666 MT/s across 8 channels. Final speed depends on DIMM population and type.

Q: Does it support virtualization features like AMD-V and SEV?
A: Yes. AMD-V, IOMMU, and SME/SEV are supported when enabled by the platform firmware.
