Description

Lenovo 4XG7B02137 AMD EPYC 9355 32-Core Processor for ThinkSystem SR645 V3

Overview

The Lenovo 4XG7B02137 is an AMD EPYC 9355 processor option for the ThinkSystem SR645 V3 server platform — a 32-core, 64-thread CPU rated at 280W TDP with a 3.55 GHz base clock. This part ships without a heatsink, so plan your thermal solution separately (Lenovo offers both standard and high-performance heatsink kits for the SR645 V3 platform). At 32 cores and 280W, the 9355 positions between lower-TDP efficiency SKUs and higher-core-count options in the EPYC Genoa lineup, making it a practical fit for mid-density compute workloads — database servers, virtualization hosts, and AI inference nodes where per-core throughput matters more than maximum thread count. The SR645 V3 supports dual-socket configurations, so a second 4XG7B02137 can be added for 64 total cores without moving to a larger chassis. The platform supports up to 6TB of DDR5 memory across 24 DIMM slots, meaning this processor can support memory-intensive analytics workloads without hitting capacity walls.

Compatibility

The 4XG7B02137 is designed exclusively for the Lenovo ThinkSystem SR645 V3 1U rack server (machine types 7D9C and 7D9D). It is not compatible with the SR645 V2 or SR635 V3 — processor socket and platform firmware are generation-specific. Within the SR645 V3, it installs in either the primary or secondary CPU socket. The server chassis supports three storage configurations (4x3.5
