Lenovo 4XH7B04304 SR650 V4 X16 G5 Rigid Riser for Cpu+mem

Lenovo 4XH7B04304 SR650 V4 X16 Gen 5 Rigid Riser for CPU and Memory

Overview

The Lenovo 4XH7B04304 is a rigid riser card designed for CPU and memory expansion in the ThinkSystem SR650 V4 server platform. It provides an X16 Gen 5 slot configuration, enabling the SR650 V4 to support additional processor and memory resources where the base chassis configuration needs to be extended. If you are commissioning or upgrading an SR650 V4 deployment — whether for a compute-dense workload, a storage-heavy configuration, or an edge infrastructure node — the 4XH7B04304 is the riser that physically enables those expansion paths. At 10 lb, this is a substantial mechanical assembly; handle and install accordingly.

Compatibility

The 4XH7B04304 is engineered specifically for the Lenovo ThinkSystem SR650 V4 server platform. It is not a universal riser — do not attempt to install it in earlier SR650 generations (V2, V3) or in other ThinkSystem chassis (SR630 V3, SR650 V3, SR860 V3) without confirming mechanical and electrical compatibility with Lenovo's configuration guide for that specific system. The X16 Gen 5 interface is paired to the SR650 V4's processor and memory subsystem architecture; fitting it to a mismatched chassis risks physical damage and will not yield a supported configuration. For full server expansion components across the ThinkSystem line, verify the target chassis model and riser slot assignment in Lenovo's SR650 V4 product guide before ordering.

Installation Notes

Installation requires access to the SR650 V4 chassis interior with the system powered down and disconnected from AC. The riser seats into a dedicated slot on the system board; consult the SR650 V4 Hardware Maintenance Guide for the correct torque specifications and seating confirmation procedure. Country of origin is Mexico. UNSPSC commodity code 43211600 (computer hardware components and accessories). No additional tools or hardware are confirmed in evidence beyond what the server's standard service kit provides — verify the SR650 V4 maintenance guide for any required fasteners specific to this riser configuration.
