Lenovo 4XG7B03701 SR650/A Xeon 6517P 16-Core Processor Option Kit
Overview
The Lenovo 4XG7B03701 is a processor option kit pairing the Intel Xeon 6517P with the ThinkSystem SR650 and SR650 A V4 platforms. The 6517P delivers 16 cores at a 3.2GHz base clock within a 190W thermal envelope — positioning it for compute-dense rack deployments where per-core performance and core count both matter. If you are configuring or expanding an SR650/SR650 A server and need a validated, factory-compatible processor upgrade, this is the option part to specify.
Key Features
- 16-Core Xeon 6517P at 3.2GHz: The 16-core configuration handles parallel workloads — video analytics, transcoding, or multi-tenant virtualization — without the per-core licensing overhead of higher core-count SKUs. The 3.2GHz base keeps single-threaded tasks responsive.
- 190W TDP: At 190W, this processor sits in the high-performance tier of the SR650 platform's supported thermal range. Verify that your SR650/SR650 A chassis cooling configuration and power supply capacity can sustain this TDP under continuous load before ordering — underpowered configurations will throttle.
- SR650/SR650 A V4 Platform Compatibility: This option kit is validated specifically for the ThinkSystem SR650 and SR650 A V4 chassis. It is not a universal Xeon drop-in — socket and firmware compatibility are platform-specific. Confirm your chassis generation before purchasing.
- Factory-New Option Kit: Sourced as a genuine Lenovo factory-new component, not a pull or refurbished part — relevant when processor provenance affects your support contract or data center intake policy.
Integration and Compatibility
The 4XG7B03701 is designed exclusively for the Lenovo ThinkSystem SR650 and SR650 A V4 server platforms. Compatibility with other ThinkSystem generations or third-party chassis is not verified by this evidence and should not be assumed. Before deployment, cross-reference against the Lenovo ServerProven compatibility matrix for your specific SR650 configuration, firmware level, and installed DIMM population — processor upgrades on populated systems sometimes require BIOS updates or memory reseating.
Frequently Asked Questions
Q: Which server platforms is the 4XG7B03701 compatible with?
A: Based on available evidence, the 4XG7B03701 is validated for the Lenovo ThinkSystem SR650 and SR650 A V4 platforms. Compatibility with other server generations is not confirmed by this evidence.
Q: What are the core count and base clock of the included processor?
A: The 4XG7B03701 includes the Intel Xeon 6517P with 16 cores at a 3.2GHz base clock frequency.
Q: What is the TDP of the processor in the 4XG7B03701?
A: The Xeon 6517P in the 4XG7B03701 has a 190W thermal design power (TDP). Confirm that your SR650 chassis cooling and power delivery can sustain this under continuous load.
Q: Is a BIOS update required before installing the 4XG7B03701?
A: Lenovo processor option kits for the SR650 V4 platform may require a specific minimum BIOS/XCC firmware level. Check the Lenovo ServerProven compatibility page for your chassis serial and current firmware version before installation.
Q: Does this come as a factory-new component?
A: Yes. The 4XG7B03701 is a factory-new Lenovo option kit — not a pull or refurbished processor.
The 4XG7B03701 is a single-item decision that carries more weight than its part number suggests — dropping a 190W processor into an SR650 V4 means your chassis power and cooling headroom need to be validated before the option kit ships, not after it arrives in the data center.
Technical Highlights:
- 16-Core / 3.2GHz: The Xeon 6517P's 16-core count at 3.2GHz base gives you the parallel thread capacity for workloads like multi-stream video analytics or VM density without inflating per-core software licensing costs the way a 32-core SKU would.
- 190W TDP: This is the spec that drives your rack planning. At 190W sustained, you need to confirm available PSU headroom in the SR650 chassis and that the installed fan modules support this thermal tier — Lenovo publishes cooling configuration requirements per processor class.
- Platform-Specific Validation: The SR650/SR650 A V4 callout in the part description is not marketing — this processor option is validated for that chassis generation specifically. Installing it in an earlier SR650 revision risks firmware incompatibility and unsupported behavior.
Deployment Considerations:
- Pull the Lenovo ServerProven entry for your exact SR650 chassis serial number before ordering — processor options can require minimum XCC2 or UEFI firmware levels that may not be installed on existing systems.
- Watch the 190W ceiling against your current PSU configuration. If the SR650 is already running dual high-TDP processors or heavy NVMe storage, a full power audit before install prevents throttling surprises under production load.
This option kit fits best in SR650 V4 deployments being configured or upgraded for compute-intensive rack workloads — multi-stream analytics servers, dense virtualization hosts, or AI inference nodes where the 16-core / 3.2GHz profile aligns with the workload mix and the chassis thermal budget has been confirmed.
