Lenovo 4XG7A37924 Xeon Silver 4216 W/o FAN

Lenovo 4XG7A37924 Xeon Silver 4216 Server Processor (No Fan)

Overview

The Lenovo 4XG7A37924 is a 2nd Generation Intel Xeon Silver 4216 processor option kit for Lenovo server and workstation platforms. Built on Intel's 14nm process at the LGA 3647 (Socket P) interface, this is a 16-core, 32-thread CPU running at a 2.1 GHz base clock with a 3.2 GHz boost frequency — positioned squarely in the mid-range of the Scalable processor stack for compute-dense rack deployments where per-core licensing costs matter more than raw per-socket peak speed. Note that the 4XG7A37924 ships without a cooling solution; a compatible heatsink or liquid cooling module is required and must be sourced separately for your specific Lenovo chassis.

Key Features

• 16 Cores / 32 Threads: More logical processors per socket means more concurrent workloads — virtualization hosts running 20–30 VMs, database servers handling parallel queries, and surveillance analytics platforms processing multiple video streams all benefit from thread density before adding a second socket. At 16 cores you stay within software licensing tiers that cap at 16 physical cores on many enterprise platforms.
• 2.1 GHz Base / 3.2 GHz Boost: The 1.1 GHz swing between base and boost gives the platform flexibility: lightly threaded tasks (single-stream analytics, control-plane processes) climb toward 3.2 GHz automatically, while sustained all-core workloads settle at the 2.1 GHz TDP floor. This matters for mixed-workload servers where not all cores are saturated simultaneously.
• 100W Thermal Design Power: A 100W TDP processor requires deliberate thermal planning. In a dense 1U or 2U Lenovo chassis, confirm the platform supports 100W TDPs in all slot positions — some chassis derate power limits for processors in specific sockets. Budget accordingly in your rack PDU calculations, especially when two sockets are populated.
• 22 MB L3 Cache: 22 MB of L3 cache shared across 16 cores — roughly 1.375 MB per core. For workloads with hot working sets (in-memory databases, video frame buffering, real-time analytics), this cache depth reduces main-memory round-trips and keeps latency predictable under load.
• LGA 3647 (Socket P): The LGA 3647 socket is the standard interface for 1st and 2nd Generation Intel Xeon Scalable processors. This processor slots into existing Lenovo platforms already designed around Socket P — confirming socket compatibility with your specific ThinkSystem or ThinkStation model before ordering is essential, as socket P platforms are not forward-compatible with 3rd Gen Ice Lake Xeons.
• UPI Bus Architecture: Intel's Ultra Path Interconnect (UPI) handles processor-to-processor and processor-to-chipset communication in multi-socket configurations. UPI delivers high-bandwidth, low-latency inter-socket traffic — relevant when this processor is paired with a second Xeon in a dual-socket Lenovo platform and workloads need coherent memory access across NUMA domains.
• 64-bit Operating Mode / 32-Thread Ceiling: All mainstream enterprise OS distributions (RHEL, Windows Server, VMware ESXi) run 64-bit natively. The 32 logical processor count is well within hypervisor scheduling limits and avoids the NUMA topology penalties that emerge on very high core-count processors when VM placement isn't pinned.
• 2nd Generation Xeon Scalable (Cascade Lake): Cascade Lake introduced hardware mitigations for Spectre and Meltdown variants that earlier Skylake-SP processors handled only in microcode — meaning these fixes are baked into silicon with lower performance overhead than software-only patches on 1st Gen platforms.

Integration and Compatibility

The 4XG7A37924 is a Lenovo option kit designed for validated compatibility with Lenovo ThinkSystem and related server platforms that carry the LGA 3647 socket. Before deploying this processor, cross-reference the Lenovo ServerProven compatibility matrix for your specific chassis model number — not all Lenovo LGA 3647 platforms support every TDP in the Xeon Scalable lineup. Thermal and power delivery requirements vary by chassis generation. Because this unit ships without a fan or heatsink, procurement must include a separately sourced thermal solution rated for 100W TDP in the target chassis. Confirm that your server's firmware (UEFI/BMC) is updated to a level that supports 2nd Generation Xeon Scalable processors; some earlier Lenovo chassis shipped with firmware that requires a field update before Cascade Lake CPUs are recognized.

Frequently Asked Questions

Q: Does the Lenovo 4XG7A37924 include a heatsink or cooling fan?

A: No. The 4XG7A37924 ships as a processor-only option kit — no fan or heatsink is included. You must source a compatible thermal solution rated for 100W TDP separately for your specific Lenovo chassis model.

Q: What socket does the Xeon Silver 4216 in the 4XG7A37924 use?

A: LGA 3647 (Socket P). This is compatible with Lenovo ThinkSystem platforms designed for 1st and 2nd Generation Intel Xeon Scalable processors. It is not compatible with 3rd Generation (Ice Lake) Xeon platforms, which use a different socket.

Q: What is the base and boost clock speed for the 4XG7A37924?

A: The processor runs at a 2.1 GHz base frequency with a Turbo Boost frequency up to 3.2 GHz, depending on active core count and thermal headroom.

Q: How many cores and threads does the 4XG7A37924 provide?

A: 16 physical cores and 32 threads via Intel Hyper-Threading. This is relevant for software licensing tiers that cap at 16 physical cores per socket.

Q: What is the TDP of the Xeon Silver 4216 in the 4XG7A37924, and what does that mean for power planning?

A: The TDP is 100W. In dual-socket configurations, plan for up to 200W of processor-only draw before accounting for memory, storage, and platform power. Confirm your chassis and PDU can support this load across all populated slots.

Q: Is the 4XG7A37924 compatible with Lenovo ThinkSystem SR650 or other specific Lenovo servers?

A: Compatibility depends on chassis model and firmware revision. Always verify against the Lenovo ServerProven database for your specific platform before ordering. The processor targets Lenovo-branded LGA 3647 server platforms validated for 2nd Generation Intel Xeon Scalable CPUs.

James Everett

When I evaluate the 4XG7A37924 for a server build, the first thing I flag is that 100W TDP number — this isn't a low-power Xeon Silver, and the no-fan shipping configuration means thermal planning is entirely on the integrator. The 16-core Cascade Lake with 22 MB L3 and a 3.2 GHz boost ceiling fits a specific workload profile well, but it demands upfront chassis validation before anything else.

Technical Highlights:

• 16 Cores at 100W TDP: That's 6.25W per core at full TDP — efficient enough for sustained all-core loads, but the 100W ceiling means chassis airflow and heatsink TDP ratings must match. Don't assume a heatsink rated for 85W Xeons will hold temperatures under extended all-core AVX workloads.
• 3.2 GHz Boost: The 1.1 GHz swing between base and boost is useful in mixed-workload environments — lightly threaded management tasks climb toward 3.2 GHz while background batch jobs stay near 2.1 GHz. In practice, on a well-cooled platform this means snappier single-threaded response without sacrificing sustained throughput.
• 22 MB L3 Cache / 32 Threads: For surveillance analytics or VMS back-end processing where video frame data is repeatedly accessed, 22 MB of shared L3 reduces memory latency across active threads. 32 logical processors give hypervisors enough scheduling headroom to avoid CPU contention on busy recording servers.

Deployment Considerations:

• This processor ships without a heatsink — confirm your Lenovo platform's thermal solution SKU before the server goes into rack. Running a 100W Xeon without a correctly rated cooler is a support liability in production.
• LGA 3647 is a Socket P platform; if your organization is mid-refresh toward 3rd Gen Xeon Scalable (Ice Lake, LGA 4189), note that this processor does not carry forward — plan your refresh timeline accordingly if this server is expected to run 5+ years.

This processor fits best in a Lenovo ThinkSystem platform deployed as a mid-tier virtualization host or VMS recording server where 16 cores covers the concurrent workload ceiling and per-core software licensing makes adding a second high-core-count socket cost-prohibitive.
