Lenovo 4XG7A63425 SR630 V2 Silver 4310 12C 120W 2.1GHZ

Lenovo 4XG7A63425 Intel Xeon Silver 4310 Processor Option for ThinkSystem SR630 V2

The Lenovo 4XG7A63425 is an Intel Xeon Silver 4310 processor option kit designed for the ThinkSystem SR630 V2 rack server. Running 12 cores and 24 threads at a 2.1 GHz base frequency with a 3.3 GHz boost, it delivers the compute headroom that enterprise workloads — including multi-channel video analytics, VMS back-end processing, and general datacenter virtualization — need without pushing into the higher TDP tiers. At 120 W TDP, this is the processor to reach for when your rack power and cooling budget matters as much as raw throughput.

Key Features

• 12 Cores / 24 Threads at 2.1–3.3 GHz: The 4310 runs 24 simultaneous threads, which translates directly to concurrent workload capacity — useful for VMS servers decoding multiple H.265 streams or hypervisors running several VMs in parallel. The 3.3 GHz boost handles burst-heavy tasks like indexing and analytics processing without a full-frequency chip.
• 18 MB Intel Smart Cache: A larger on-die cache reduces main-memory round-trips for data-intensive applications. On a surveillance analytics server processing motion detection or object recognition across dozens of streams, this lowers latency on repeated data pattern lookups.
• 120 W Thermal Design Power: At 120 W TDP, this processor fits within the SR630 V2's thermal envelope without requiring upgraded cooling infrastructure. If your deployment is in a space-constrained or thermally limited rack, 120 W is the ceiling that keeps standard cooling viable — a meaningful difference versus higher-wattage 3rd Gen Xeon Scalable options.
• 3rd Generation Intel Xeon Scalable (Ice Lake, 10 nm): The 10 nm Ice Lake architecture delivers improved IPC over prior Cascade Lake generation, meaning more work per clock cycle. For always-on server workloads that can't be overclocked, per-core efficiency is the only lever — Ice Lake moves it meaningfully.
• LGA 4189 Socket, SR630 V2 Platform: The LGA 4189 socket is specific to the Ice Lake Xeon Scalable platform. This processor is qualified for the ThinkSystem SR630 V2 — verify your target server's compatibility matrix before ordering, as LGA 4189 is not cross-compatible with earlier SR630 (LGA 3647) platforms.
• 10.4 GT/s System Bus Rate: The UPI (Ultra Path Interconnect) runs at 10.4 GT/s, supporting the memory bandwidth and I/O throughput the SR630 V2's dual-socket architecture requires for coherent multi-processor configurations.
• 64-Bit Operating Mode: Full 64-bit execution is standard for any modern enterprise workload — this confirms compatibility with current hypervisors (VMware vSphere, Microsoft Hyper-V, Linux KVM) and operating systems without legacy mode limitations.
• Tray Package — No Cooler Included: This is a tray-packaged processor, not a boxed retail unit. No heatsink or cooler ships with it. For SR630 V2 deployments, Lenovo's platform-specific heatsink options are required separately — standard or performance heatsink depending on processor TDP and airflow configuration.

Integration and Compatibility

The 4XG7A63425 is a Lenovo-qualified option part for the Lenovo ThinkSystem server line, specifically the SR630 V2. It belongs to the server and storage category of datacenter compute components. Verify compatibility via Lenovo's SR630 V2 configuration guide before pairing with specific memory, storage, or PCIe options — Xeon Scalable Ice Lake platforms have specific memory channel and DIMM population rules that affect performance. For security integrators building a multi-channel NVR or VMS server, pairing this processor with sufficient RAM (at least 64 GB for 32+ camera streams with analytics) and a capable storage subsystem is the correct planning sequence. Review a VMS server selection guide for channel-count-to-CPU-core sizing guidance. Complementary infrastructure — including PoE network switches for camera connectivity — should be scoped in parallel with server compute planning.

Frequently Asked Questions

Q: Is the 4XG7A63425 compatible with the original ThinkSystem SR630 (non-V2)?

A: No. The 4XG7A63425 uses the LGA 4189 socket (3rd Gen Intel Xeon Scalable / Ice Lake). The original SR630 uses LGA 3647 (Skylake/Cascade Lake). The two sockets are physically and electrically incompatible — this processor only installs in the SR630 V2 or other LGA 4189 platforms qualified by Lenovo.

Q: Does the 4XG7A63425 include a heatsink or cooler?

A: No. This is a tray-packaged processor. No heatsink, cooler, or thermal interface material ships with it. You will need to order the appropriate Lenovo heatsink option for the SR630 V2 separately, sized to the 120 W TDP of this processor.

Q: What is the base and boost clock speed of the Xeon Silver 4310?

A: The Intel Xeon Silver 4310 runs at a 2.1 GHz base frequency with a 3.3 GHz maximum boost frequency, across 12 cores and 24 threads.

Q: How many cores and threads does the 4XG7A63425 provide?

A: 12 physical cores with 24 threads via Intel Hyper-Threading. This makes it suitable for concurrent multi-VM or multi-stream workloads where thread count matters more than single-core clock speed.

Q: What is the TDP and what are the cooling implications?

A: The Xeon Silver 4310 has a 120 W Thermal Design Power. Within the SR630 V2, this fits the standard airflow and heatsink configuration, but you must use a Lenovo-qualified heatsink — not an aftermarket solution — to maintain platform thermal compliance and warranty coverage.

Q: What server workloads is this processor well-suited for?

A: The 12-core / 24-thread profile at 120 W TDP is a strong fit for mid-density virtualization, multi-channel video management server (VMS) back-ends, database workloads, and enterprise application servers where power efficiency and per-core throughput are both priorities. It is less suited to workloads requiring maximum single-threaded clock speed.

Jerry Tildsen

The Lenovo 4XG7A63425 is the processor option I reach for when building out a mid-density ThinkSystem SR630 V2 for video management or enterprise virtualization — specifically because the Xeon Silver 4310 holds a 120 W TDP while delivering 12 cores and 3.3 GHz burst. That power envelope keeps you in standard cooling territory on a dual-socket SR630 V2 without sacrificing the thread count you need for concurrent stream decoding or VM density.

Technical Highlights:

• 12C/24T at 2.1–3.3 GHz: 24 threads handle concurrent workloads — on a VMS back-end, each decode thread for H.265 consumes roughly 0.5–1 core depending on resolution; 12 cores gives you headroom for 16–24 camera streams plus analytics without pegging the CPU.
• 18 MB Smart Cache: Larger L3 cache reduces memory latency on repetitive data patterns — particularly relevant for database queries and motion-detection heuristics that re-access similar data blocks in tight loops.
• 10 nm Ice Lake architecture: IPC uplift over Cascade Lake means this 12-core Silver outperforms the previous-generation 12-core Silver on per-thread throughput — the same TDP buys more actual work per clock cycle.

Deployment Considerations:

• This is a tray processor with no heatsink — plan your Lenovo heatsink option order at the same time. The SR630 V2 has distinct standard and performance heatsink SKUs; at 120 W you are at the upper boundary of the standard heatsink's rated TDP on some configurations — confirm with the SR630 V2 thermal design guide.
• LGA 4189 is Ice Lake-exclusive — if your SR630 chassis is the original V1 (LGA 3647), this processor will not physically seat. Double-check the server generation before ordering; the V1 and V2 look similar in rack but are not processor-interchangeable.

For a security operations center running a 32-camera Milestone XProtect or Genetec deployment with server-side analytics, the SR630 V2 populated with this 4XG7A63425 and 64–128 GB RAM is a well-matched platform — enough thread count for stream processing, conservative enough on power to fit a standard rack PDU circuit.
