Lenovo 4XG7A07236 SR570 Xeon 6126 12C/125W/2.6GHZ

Lenovo 4XG7A07236 Xeon Gold 6126 12-Core Processor Option for ThinkSystem SR570

Overview

The Lenovo 4XG7A07236 is a factory-configured Intel Xeon Gold 6126 processor option kit designed for the Lenovo ThinkSystem SR570 server platform. Rated at 125W TDP with 12 cores, 24 threads, and a 2.6 GHz base clock that turbos to 3.7 GHz, it fits the LGA 3647 (Socket P) socket and targets workloads that need a solid per-core frequency ceiling alongside parallel thread capacity — surveillance recording servers, video analytics nodes, and mid-range compute deployments where the SR570's 2-socket architecture can be populated with a second processor to double throughput without a platform change.

Built on Intel's first-generation Xeon Scalable (Skylake, 14nm) microarchitecture with the H0 stepping, the 4XG7A07236 supports up to 768 GB of internal memory per processor — enough headroom for in-memory analytics databases or large VMS buffer pools. The cooler is included in the kit, so no separate thermal solution is required for standard SR570 rack deployments.

Key Features

• 12 Cores / 24 Threads at 2.6 GHz Base: The Xeon Gold 6126 runs 24 simultaneous threads, which maps directly to how many parallel decode or analytics tasks a VMS can schedule without context-switch overhead. At 2.6 GHz base, per-thread compute is stronger than lower-frequency many-core parts — relevant when your VMS relies on single-threaded decode paths per channel.
• 3.7 GHz Turbo Boost: Under bursty load — motion event spikes, forensic playback, or batch export — individual cores can reach 3.7 GHz. That 1.1 GHz headroom above base frequency means latency-sensitive operations complete faster without permanently running the processor hot.
• 19.25 MB L3 Cache: A large last-level cache reduces main-memory fetch latency for working sets that cycle repeatedly — frame buffers, codec tables, and analytics model weights all benefit. Fewer cache misses translate to more consistent decode throughput under sustained load.
• 125W TDP — Managed Thermal Envelope: At 125W, this processor sits in the middle of the Xeon Gold power band. The SR570's chassis thermals are rated for this TDP, and the included cooler handles it within spec. Know your rack power budget: a dual-socket SR570 with two of these draws 250W in processor TDP alone before DRAM, storage, and NIC load.
• 768 GB Maximum Memory Support: The platform supports up to 768 GB addressable memory per processor. For large-scale NVR deployments running analytics on 64+ channels, or for hypervisor hosts where VM memory allocation is the constraint, this ceiling is rarely a limiting factor.
• LGA 3647 Socket P — SR570-Specific: This processor is keyed to the SR570 platform. It will not drop into SR530, SR590, or other ThinkSystem chassis without verifying socket and board revision compatibility. If you are populating a second socket on an existing SR570, confirm the board supports multi-socket configuration before ordering.
• 64-Bit Operating Modes / Skylake Microarchitecture: Full 64-bit instruction set support covers every enterprise OS and hypervisor in production use. The Skylake core supports AVX-512, which accelerates certain deep-learning inference workloads if your analytics software is compiled to use it.
• Cooler Included: The kit ships with the thermal solution — no additional procurement step for the heatsink. For standard 1U/2U SR570 rack deployments, this is drop-in ready.

Integration & Compatibility

The 4XG7A07236 is a Lenovo-qualified option for the ThinkSystem SR570 server platform. Because Lenovo validates processor options against specific firmware and board revisions, always cross-reference the SR570's Hardware Compatibility List (HCL) before installation. The LGA 3647 socket is shared across several Xeon Scalable platforms, but thermal, power delivery, and BIOS support vary — do not assume cross-platform compatibility without HCL verification.

For deployments pairing this server with IP surveillance infrastructure, the SR570 running this processor can comfortably serve as a network video recorder host or an edge analytics node. Pair it with sufficient DRAM and NVMe storage to match your channel count and retention window. Reference the PoE network switch category if you are also provisioning camera infrastructure alongside the server build.

The processor's 768 GB memory ceiling and 24-thread count also make the SR570/6126 combination a reasonable candidate for rack server virtualization hosts running 4–8 concurrent VM workloads, particularly in environments that need a balance of core count and per-core frequency rather than maximum core density.

Frequently Asked Questions

Q: Is the Lenovo 4XG7A07236 compatible with ThinkSystem SR570 servers only, or does it fit other Lenovo platforms?

A: The 4XG7A07236 is a Lenovo-qualified option kit for the ThinkSystem SR570. While the underlying Intel Xeon Gold 6126 uses the LGA 3647 (Socket P) interface shared across several Skylake-SP platforms, Lenovo qualifies processor options per-chassis. Always verify compatibility against the SR570 Hardware Compatibility List before installing in any other ThinkSystem model.

Q: Does the 4XG7A07236 include a heatsink or cooler?

A: Yes. The kit includes a cooler, so no separate thermal solution is required for standard SR570 rack deployments.

Q: What is the maximum memory supported with the Xeon Gold 6126 in the SR570?

A: The Xeon Gold 6126 supports up to 768 GB of internal memory per processor. In a dual-socket SR570 configuration, total addressable memory capacity scales accordingly, subject to the SR570 platform's DIMM slot count and supported memory speeds.

Q: What is the processor's base and boost frequency?

A: The Xeon Gold 6126 runs at 2.6 GHz base frequency with Intel Turbo Boost up to 3.7 GHz under single- or lightly-threaded loads.

Q: How many cores and threads does the 4XG7A07236 provide?

A: The Xeon Gold 6126 delivers 12 physical cores and 24 threads via Intel Hyper-Threading, operating in 64-bit mode.

Q: What is the thermal design power (TDP) of this processor?

A: The Xeon Gold 6126 has a 125W TDP. Plan rack power budgets accordingly — a dual-socket SR570 configuration draws 250W in processor TDP before accounting for DRAM, storage, and networking load.

The 4XG7A07236 is a processor option I'd reach for specifically when a ThinkSystem SR570 deployment needs more per-core headroom than a lower-frequency 14-core or 16-core part provides. The Xeon Gold 6126's 3.7 GHz turbo ceiling is the detail that matters most on surveillance and analytics workloads where several VMS threads are decode-bound rather than memory-bound — those threads benefit from clock rate, not core count.

Technical Highlights:

• 2.6 GHz Base / 3.7 GHz Turbo: A 1.1 GHz turbo window gives bursty decode and analytics tasks a meaningful per-thread speed advantage. For forensic playback or motion-triggered analytics spikes, that headroom keeps response latency low without requiring a higher-TDP processor.
• 19.25 MB L3 Cache: Large enough to hold codec working sets and analytics model state for a moderate channel count in cache, reducing main-memory round-trips and smoothing decode throughput under sustained multi-stream load.
• 125W TDP with Included Cooler: The kit ships thermal-solution-ready for the SR570. No separate cooler procurement. That said, verify your SR570 chassis revision supports this TDP at the ambient temperature of your IDF closet or server room — high-ambient deployments (above 30°C inlet) need careful airflow validation.

Deployment Considerations:

• The LGA 3647 socket is mechanically shared across multiple Xeon Scalable platforms, but BIOS and power delivery qualification is per-chassis. Do not install this kit in a non-SR570 platform without explicit Lenovo HCL confirmation — mismatch risks boot failure or thermal shutdown.
• At 125W TDP, a dual-socket SR570 pulls 250W from processor load alone. Budget rack PDU capacity with full DRAM, NVMe, and dual-port NIC load factored in — first-gen Xeon Scalable systems with high DRAM populations can approach 400–450W system draw under sustained analytics load.

For a physical security operations center building out an on-premise analytics or NVR server on the SR570 platform, the 4XG7A07236 is the right processor choice when you need higher single-thread performance over maximum core count — particularly for VMS platforms that schedule one thread per decode channel rather than vectorizing across all cores.
