Lenovo 7XG7A05544 SR630 Xeon 6128 6C/115W/3.4GHZ

Lenovo 7XG7A05544 Intel Xeon Gold 6128 Processor for ThinkSystem SR630

Overview

The Lenovo 7XG7A05544 is a factory-configured Intel Xeon Gold 6128 processor option designed for installation in the Lenovo ThinkSystem SR630 1U rack server. Rated at 3.4 GHz base with a 3.7 GHz Turbo Boost ceiling, six physical cores, and a 115W TDP, this is a mid-range workload processor — sensibly positioned for mixed enterprise and light virtualization workloads where core density matters less than per-core clock performance. If you're speccing a new SR630 build or adding a second processor to an existing single-socket configuration, the 7XG7A05544 is the component to specify.

Key Features

• 3.4 GHz Base / 3.7 GHz Boost Clock: Higher per-core frequency than many of its Xeon Gold peers in the same tier — benefits single-threaded workloads and latency-sensitive applications like database query engines or simulation tasks that don't scale well across many cores.
• 6 Cores / 12 Threads (Hyper-Threading): Twelve logical processors available to the OS and hypervisor. For VM-dense SR630 deployments, this means up to 12 vCPUs per socket — manageable in small-to-mid virtualization clusters without over-provisioning physical cores.
• 19.25 MB L3 Cache: Intel's Last Level Cache at this size keeps frequently accessed working sets in-package, reducing latency on cache-sensitive workloads. For video analytics servers or database-front-end roles, larger L3 materially reduces DRAM fetch cycles.
• 115W TDP: Fits within the SR630's thermal envelope with the included cooler — no need to source additional thermal hardware. At 115W, this processor sits in the mid-range power band for the Xeon Gold family, making it compatible with standard SR630 power supply configurations.
• LGA 3647 (Socket P), 14nm Skylake Microarchitecture: First-generation Intel Scalable architecture. This is a verified SR630-native socket — no adapters, no compatibility guesswork. The Skylake stepping (H0) is a mature, stable stepping with full firmware and microcode support from Lenovo.
• Up to 768 GB Maximum Memory: The processor's memory controller supports up to 768 GB of DDR4 RAM across the SR630's DIMM slots. For in-memory database workloads, large analytics caches, or memory-heavy virtual machine pools, this ceiling gives substantial room to scale without swapping to storage.
• 64-Bit Operating Mode: Full 64-bit instruction set support — required for any modern enterprise OS (Windows Server, RHEL, Ubuntu Server, VMware ESXi). No 32-bit constraint concerns.
• Cooler Included: The 7XG7A05544 ships with a compatible processor cooler, eliminating a common gotcha when ordering OEM processor options separately. Verify heatsink compatibility with the SR630 chassis airflow configuration before installation.

Integration & Compatibility

This processor is a Lenovo OEM option for the Lenovo ThinkSystem server line, specifically validated for the SR630 platform. The LGA 3647 socket and First Generation Intel Scalable support mean it pairs with SR630 boards running Lenovo's firmware ecosystem — UEFI/BIOS updates, XClarity Administrator management, and Intel's standard DCAI feature set including AVX-512 instruction extensions.

When deploying in a 1U rack server role for video surveillance infrastructure — such as a VMS compute node running Milestone XProtect, Genetec Security Center, or Avigilon Control Center — the 6128's 3.4 GHz base clock provides reliable single-stream decode performance. For NVR and VMS server builds, pair this processor with adequate DDR4 memory and a PCIe NVMe storage array for sustained concurrent stream handling. Consult a server configuration guide to right-size memory and storage against your expected camera channel count and retention window.

Integrators building out a surveillance compute platform should note that the SR630's dual-socket capability allows a second 7XG7A05544 to be added later — useful if initial channel counts are modest and growth is expected. Plan your DIMM population and power supply sizing to accommodate a second processor from day one.

Frequently Asked Questions

Q: Is the 7XG7A05544 compatible with the Lenovo ThinkSystem SR630?

A: Yes. The 7XG7A05544 is a Lenovo OEM processor option validated for the SR630 platform. It uses the LGA 3647 (Socket P) socket and is a First Generation Intel Xeon Scalable part, which matches the SR630's processor support list.

Q: Does this processor include a heatsink/cooler?

A: Yes. The 7XG7A05544 includes a cooler. Verify compatibility with your specific SR630 chassis airflow and heatsink bay configuration before installation.

Q: What is the TDP of the Xeon Gold 6128?

A: The Intel Xeon Gold 6128 has a Thermal Design Power (TDP) of 115W. This is within the standard SR630 thermal envelope when paired with the included cooler.

Q: How many cores and threads does the 7XG7A05544 provide?

A: Six physical cores with Hyper-Threading enabled, providing 12 logical threads to the operating system or hypervisor.

Q: What is the maximum RAM supported by this processor?

A: The Intel Xeon Gold 6128 supports up to 768 GB of DDR4 memory per socket, subject to the SR630 motherboard's DIMM slot configuration.

Q: Can this processor be used in a dual-socket SR630 configuration?

A: The SR630 supports dual-socket configurations. A second 7XG7A05544 can be installed in the second processor socket to double core count and memory capacity — useful for scaling VMS or virtualization workloads without replacing the server.

Marty Allison

The 7XG7A05544 is one of those processor options that makes the most sense when you know exactly what workload you're sizing for. The Xeon Gold 6128 hits 3.4 GHz base and boosts to 3.7 GHz — that's meaningful clock speed in the Gold tier — with a 115W TDP that stays within the SR630's standard thermal design. If you're building a VMS compute node or a light virtualization host rather than a dense core-count HPC node, this is a sensible fit.

Technical Highlights:

• 3.7 GHz Turbo Boost: When a workload thread can monopolize a core — video decode, database query, real-time analytics — this processor climbs to 3.7 GHz, which directly reduces per-frame processing latency on high-resolution VMS streams.
• 19.25 MB L3 Cache: Keeps hot working sets in-package. For NVR indexing or concurrent RTSP stream buffering, a larger L3 reduces the frequency of main memory round-trips, which at DDR4 latencies adds up quickly across dozens of concurrent sessions.
• 768 GB Max Memory Ceiling: Rarely hit in a 6-core config, but it means the platform isn't memory-constrained if you need large in-memory caches or dense VM memory allocation — scale memory freely without hitting a processor-imposed wall.

Deployment Considerations:

• The Skylake H0 stepping is mature and carries full Lenovo XClarity firmware support — microcode and BIOS updates are available through standard Lenovo update channels, which matters for long-lifecycle enterprise deployments.
• At 6 cores / 12 threads, this is not the right pick for highly parallelized workloads like AI inference at scale or dense container orchestration — for those scenarios, look at higher core-count Gold or Platinum options in the SR630 family.

Best-fit deployment: a Lenovo SR630 configured as a mid-tier VMS server handling 32–64 camera channels under Milestone or Genetec, where per-core clock speed drives decode throughput more than raw core count — and where the 115W TDP fits within a standard rack PDU circuit budget.
