Lenovo 4XG7B03700 ThinkSystem SR650 Xeon Silver 6507P Processor Option Kit
Overview
The Lenovo 4XG7B03700 is a factory-configured processor option kit designed specifically for the ThinkSystem SR650 and SR650/A V4 platforms. It installs an Intel Xeon Silver 6507P — an 8-core, 3.5GHz processor rated at 150W TDP — into qualifying SR650-series servers as a primary or secondary socket population. If you're provisioning or expanding SR650/A V4 compute capacity and need a mid-range Xeon Silver with a relatively high base clock for a Silver-class part, this is the kit to specify.
The 6507P's 3.5GHz base frequency positions it toward the higher end of the Xeon Silver 6500-series base clock range, which translates to stronger single-threaded and lightly threaded workload performance compared to higher-core-count Silver variants that trade clock speed for density. For workloads that don't scale linearly across many cores — certain database engines, per-core-licensed software stacks, or latency-sensitive middleware — that clock headroom matters more than raw core count.
Key Features
- 8-Core Xeon Silver 6507P at 3.5GHz base: Balances per-core throughput with a manageable core count, useful in environments where software licensing is per-core and you need to control license footprint without sacrificing clock speed.
- 150W TDP: Falls within the SR650/A V4 platform's supported processor power envelope. Verify your chassis cooling configuration and power supply headroom before installing alongside a second high-TDP processor — dual 150W sockets draw 300W from processor power alone.
- Platform-specific option kit: The 4XG7B03700 is validated for the ThinkSystem SR650 and SR650/A V4; it is not a retail-boxed CPU and should not be installed in non-supported chassis. Lenovo option kits include the processor and all required hardware for installation in the target platform.
- Factory-new, genuine component: Sourced as a genuine Lenovo option kit — no grey-market, no parallel imports — ensuring full platform compatibility and eligibility for Lenovo support coverage.
Integration and Compatibility
This processor option is validated exclusively for the ThinkSystem SR650 and SR650/A V4 server platforms. Before ordering, confirm your SR650/A firmware level meets the minimum required for 6507P support — Lenovo publishes supported processor matrices in the SR650 Product Guide. For dual-processor configurations, both sockets must be populated with identical processor models. Memory configuration requirements scale with processor population; consult the SR650/A V4 memory configuration guide for supported DIMM counts and speeds with this processor installed.
Frequently Asked Questions
Q: Which server platforms is the 4XG7B03700 compatible with?
A: The 4XG7B03700 is validated for the Lenovo ThinkSystem SR650 and SR650/A V4 platforms. It is a platform-specific option kit and is not interchangeable with other server lines.
Q: What processor does the 4XG7B03700 install?
A: It installs an Intel Xeon Silver 6507P — an 8-core processor with a 3.5GHz base frequency and 150W TDP — into the target SR650/A V4 chassis.
Q: Can I install two 4XG7B03700 kits in a dual-socket SR650?
A: Dual-processor SR650/A V4 configurations require both sockets to use identical processor models. Two units of the 4XG7B03700 can be installed together, but verify your chassis power supply and cooling configuration supports the combined 300W processor TDP load before commissioning.
Q: Is the 4XG7B03700 a retail-boxed CPU or an OEM option kit?
A: It is a Lenovo-validated OEM option kit, not a retail-boxed processor. It includes the processor and platform-specific installation hardware, and is intended for installation in supported Lenovo ThinkSystem SR650/A V4 servers only.
Q: What is the weight of the 4XG7B03700 kit?
A: The kit ships at 10.00 lb, which includes the processor, heatsink (if included in the option kit), and packaging.
The 4XG7B03700 is one of those option kits that gets overlooked because the Xeon Silver line doesn't generate much excitement — but the 6507P's 3.5GHz base clock is genuinely the right call for SR650/A V4 deployments where you're running per-core-licensed workloads and need to keep the license count honest without giving up throughput on lightly threaded jobs.
Technical Highlights:
- 3.5GHz base clock: Higher than most Silver-tier parts at this core count — relevant when your workload doesn't parallelize well and single-thread speed determines your response latency.
- 8 cores at 150W TDP: A deliberate tradeoff — you're getting fewer cores than a Gold-class part but staying within a power envelope that most SR650/A cooling configurations handle without upgrades.
- Platform-validated kit: Shipped as a Lenovo option kit means the processor, heatsink bracket, and retention hardware are matched to the SR650/A V4 board — no sourcing separate thermal interface components or hoping a retail heatsink clears the riser clearance.
Deployment Considerations:
- Always check the SR650/A V4 firmware compatibility matrix before installing — Xeon 6000-series support requires a minimum XCC/UEFI firmware level that older SR650 images may not meet.
- At 150W per socket, a dual-processor SR650/A with two of these draws significant power at the processor rail alone — budget your PSU headroom and chassis airflow before committing to a 2P configuration in a thermally dense rack.
This processor option fits best in SR650/A V4 builds running per-core-licensed middleware, light-to-moderate virtualization hosts where base clock matters more than core density, or as a cost-managed primary socket while leaving the second socket for future expansion.
