Lenovo 4XG7A37929 Xeon Silver 4214 W/o FAN

Lenovo 4XG7A37929 Intel Xeon Silver 4214 12-Core Server Processor

Overview

The Lenovo 4XG7A37929 is a factory-genuine OEM tray processor — Intel's 2nd Generation Xeon Silver 4214 — spec'd for Lenovo ThinkSystem servers where a compute upgrade or CTO socket population is needed without redundant cooling hardware. Rated at 85W TDP with 12 cores, 24 threads, and a 3.2 GHz boost clock, this is the workhorse mid-range processor in the Lenovo server scalable family: enough parallel throughput for virtualization hosts, VMS recording servers, and edge analytics workloads, without the power and thermal overhead of the higher-tier Gold or Platinum SKUs.

If you're sizing a server processor for a Milestone, Genetec, or Avigilon-based VMS platform, or populating a second socket in a dual-socket ThinkSystem node, the 4XG7A37929 slots into the LGA 3647 (Socket P) without a separate cooler — plan your thermal solution before ordering.

Key Features

• 12 Cores / 24 Threads at 2.2 GHz Base, 3.2 GHz Boost: Intel's Cascade Lake architecture gives you 24 hardware threads for concurrent VM execution or multi-stream video decoding. At 2.2 GHz base the processor sustains steady encode/decode throughput; the 3.2 GHz single-core boost handles latency-sensitive tasks like live analytics or access-control event processing without manual tuning.
• 85W TDP — Mid-Range Power Envelope: At 85W, this processor fits comfortably within Lenovo's standard ThinkSystem thermal design. It draws meaningfully less power than the 125W Gold-class parts while delivering comparable core counts — relevant in dense rack deployments where PDU capacity and cooling airflow budgets are fixed.
• 17 MB L3 Cache: The 17 MB last-level cache reduces main-memory fetch latency on workloads with large working sets — database-backed VMS configurations, multi-tenant virtualization, and AI inference pipelines all benefit from keeping hot data closer to execution units.
• LGA 3647 (Socket P) — Dual-Socket Capable: Socket P supports symmetric multi-processing, so a second 4XG7A37929 can be added to a dual-socket ThinkSystem chassis for linear core-count scaling. That's a cost-effective path to 24 cores / 48 threads without a full platform change. Check your specific ThinkSystem model's QVL to confirm socket population rules.
• 14nm Stepping L1 — Production Silicon: Cascade Lake at 14nm with Stepping L1 reflects mature, fully validated silicon. Lenovo OEM tray parts are factory-new, genuine Intel production units — not remarked or grey-market pulls — which matters for platform stability under 24/7 server workloads.
• UPI Bus Interconnect: Ultra Path Interconnect (UPI) links the two sockets in a dual-processor configuration with low-latency, high-bandwidth coherent fabric. In a dual-socket NVR or analytics server, UPI prevents the NUMA bottlenecks that can degrade throughput when one CPU needs data owned by the other.
• 64-bit Operating Mode — Full OS Support: Supports all current 64-bit server operating systems (Windows Server, RHEL, Ubuntu Server, VMware ESXi) without compatibility workarounds.
• Tray Format — No Cooler Included: OEM tray packaging means the system integrator supplies the appropriate heatsink for the chassis. Lenovo ThinkSystem heatsinks are chassis-specific; confirm the correct heatsink part number for your ThinkSystem model before deploying.

Integration and Compatibility

The 4XG7A37929 is a Lenovo-sourced OEM tray unit designed for ThinkSystem platforms that use the LGA 3647 / Socket P form factor. It is a 2nd Generation Intel Xeon Scalable processor (Cascade Lake), which is compatible with Lenovo ThinkSystem servers that support the 2nd Gen Xeon Scalable family — confirm via the Lenovo ServerProven compatibility database for your specific chassis model (SR530, SR550, SR630, SR650, and similar).

For server platform planning, note that 1st Gen Skylake-SP and 2nd Gen Cascade Lake-SP processors share the Socket P footprint but require BIOS updates on many platforms before a 2nd Gen CPU is recognized. Verify firmware revision on the target system before swapping processors in a live environment.

Pair with compatible server memory — the Xeon Silver 4214 supports DDR4-2400 in up to 6 channels per socket (12 DIMMs per socket in a dual-socket chassis). Max memory bandwidth scales with DIMM population; fully populating all channels maximizes throughput for memory-bound workloads like large VMS databases or in-memory analytics caches.

Frequently Asked Questions

Q: Does the Lenovo 4XG7A37929 include a heatsink or cooling fan?

A: No. The 4XG7A37929 is a tray-only processor — no heatsink or fan is included. You must supply the correct Lenovo ThinkSystem heatsink for your specific chassis model. Do not install this processor without a compatible thermal solution.

Q: Which Lenovo ThinkSystem servers is the 4XG7A37929 compatible with?

A: This is a 2nd Generation Intel Xeon Scalable (Cascade Lake) processor in LGA 3647 / Socket P. It is designed for Lenovo ThinkSystem servers that support 2nd Gen Xeon Scalable CPUs. Verify your specific chassis model via the Lenovo ServerProven compatibility tool and confirm BIOS firmware supports 2nd Gen Xeon Scalable processors before installation.

Q: Can this processor be used in a dual-socket configuration?

A: Yes. The LGA 3647 (Socket P) platform supports symmetric dual-socket configurations. If your ThinkSystem chassis supports two sockets, a second 4XG7A37929 can be installed for a combined 24 cores and 48 threads. Both processors must be identical for a matched dual-socket deployment.

Q: What is the base and boost clock speed of the Xeon Silver 4214?

A: The processor runs at 2.2 GHz base frequency with a maximum turbo boost of 3.2 GHz. The 12 cores and 24 threads operate across this range depending on thermal headroom and workload distribution.

Q: What is the TDP of the 4XG7A37929 and does it affect rack power planning?

A: The Thermal Design Power is 85W. This is a mid-range figure for the Xeon Silver class — lower than Gold-tier 125W+ parts with similar core counts. For dense rack deployments, this matters for PDU circuit budgeting and per-chassis thermal airflow requirements.

Q: Is this processor a grey-market or pulled unit?

A: No. The 4XG7A37929 is sourced as a factory-new, genuine Lenovo OEM tray processor through channel-direct distribution — no grey-market sourcing, no parallel imports.

When I spec the 4XG7A37929 into a project, it's almost always for one of two scenarios: populating a second socket in a dual-socket ThinkSystem to double core count without a chassis swap, or right-sizing compute for a mid-density VMS server where the 125W Gold parts are overkill for the power and cooling budget available. The 85W TDP is the number that drives that decision — it's 32% lower than a comparable 12-core Gold-class part, and in a four-node rack that adds up fast on the PDU circuit.

Technical Highlights:

• 12C/24T at 3.2 GHz Boost: For Milestone or Genetec environments running 20–30 camera streams with edge analytics enabled, 24 threads at up to 3.2 GHz handles concurrent decode and motion analysis without pegging the scheduler — this is the realistic operating range for a mid-tier VMS node.
• 17 MB L3 Cache: VMS database queries and analytics inference both thrash main memory if the working set doesn't fit in cache. 17 MB L3 meaningfully reduces DRAM fetch latency compared to smaller-cache Silver-class parts — noticeable in multi-tenant VM environments sharing the same physical host.
• UPI Dual-Socket Fabric: In a dual-socket configuration, UPI keeps cross-socket memory access coherent and fast. Without it, NUMA asymmetry can quietly degrade throughput on workloads that don't pin threads to a single socket — which most VMS platforms don't do by default.

Deployment Considerations:

• No heatsink is included — this is an OEM tray part. The correct Lenovo ThinkSystem heatsink is chassis-specific (high-performance vs. standard airflow variants exist); ordering the wrong one is a common field error. Verify the heatsink part number against your exact chassis model before the system ships.
• 2nd Gen Xeon Scalable requires BIOS support — if you're upgrading a 1st Gen Skylake-SP system, a firmware update is mandatory before the processor is recognized. Some platforms need an interim CPU installed to perform the update. Plan this into your deployment timeline.

The 4XG7A37929 is the right call for a dual-socket ThinkSystem VMS server running 24/7 multi-camera recording with light analytics — where you need the core count of a Gold-class platform at a materially lower power draw, and chassis thermal headroom is a real constraint rather than a theoretical one.
