Description

AMD EPYC 7543P is a single-socket–optimized Milan processor delivering 32 cores, 256MB L3, and robust per-core performance for cost-efficient 1P servers. It provides 8-channel DDR4-3200 ECC and up to 128 lanes of PCIe 4.0 for dense storage and accelerator I/O on SP3 platforms. Ideal for virtualization hosts, databases, and analytics where 1P consolidation reduces TCO.

Features

- Single-socket optimization for lower TCO without sacrificing I/O
- 32 cores with 256MB L3 for virtualization and database performance
- 128 lanes of PCIe 4.0 for dense NVMe and accelerator connectivity
- 8-channel DDR4-3200 ECC for high memory bandwidth
- Zen 3 architecture improves IPC and latency
- Advanced security features including SEV family (platform dependent)

FAQs

Q: Is the 7543P compatible with dual-socket motherboards?
A: It is designed for single-socket (1P) operation only and cannot be paired in 2P configurations.

Q: What platform is required?
A: An SP3 server platform with BIOS supporting EPYC 7003 (Milan); check your server vendor’s CPU support list.

Q: Is a heatsink included?
A: Typically CPU only; use the server-approved heatsink and retention hardware.

Q: What memory does it support?
A: Up to DDR4-3200 ECC across 8 channels; speeds depend on DIMM type and population.

Q: How many PCIe lanes are available in 1P?
A: Up to 128 lanes of PCIe 4.0 are available from the CPU (platform dependent).
