Lenovo 4XG7A09076 SR590 Xeon 4114T 10C/85W/2.2GHZ

Lenovo 4XG7A09076 ThinkSystem SR590 Xeon Silver 4114T 10-Core Processor Option Kit

Overview

The Lenovo 4XG7A09076 is a factory-new processor option kit that installs a 1st Generation Intel Xeon Silver 4114T into the Lenovo ThinkSystem SR590 — a two-socket 2U rack server built for dense, thermally constrained data center environments. The 4114T is the thermally optimized variant of the Silver 4114, rated at 85W TDP rather than the standard 105W, which matters in high-density deployments where aggregate rack power draw or cooling headroom is a real constraint. If you are adding compute capacity to an existing SR590 and need a second socket populated, or replacing a failed processor, the 4XG7A09076 is the correct SKU to specify. Fabricated in Mexico on a 14nm Skylake process node, this kit arrives factory-new and genuine — no grey-market, no parallel imports.

Key Features

• 10 Cores / 20 Threads at 2.2 GHz Base, 3.0 GHz Boost: Ten physical cores with Hyper-Threading give the OS 20 logical processors to schedule across. The 2.2 GHz base is conservative by design — sustained all-core throughput stays predictable under heavy parallel workloads like VMS recording, transcoding, or database query processing. The 3.0 GHz single-core boost handles bursty, latency-sensitive tasks without needing a higher-binned SKU.
• 85W Thermal Design Power — the T-variant efficiency advantage: At 85W versus the standard 4114's 105W, you save 20W per socket. In a dual-socket SR590 that is 40W per server — meaningful when you are filling a rack with compute nodes and working against a per-rack PDU limit or a cooling envelope. If your data center charges for power draw or enforces strict rack density policies, the T-suffix is the right call.
• 13.8 MB L3 Cache (Skylake architecture): Intel's LLC (Last Level Cache) on this generation is shared across all 10 cores, reducing main memory round-trips for working sets that fit. For NVR and VMS server workloads handling concurrent stream decoding, a larger shared cache reduces latency spikes during simultaneous motion-detection analytics passes.
• LGA 3647 (Socket P) — SR590-specific socket: The LGA 3647 package is keyed to Skylake-SP and Cascade Lake-SP server platforms. This processor installs into the SR590's primary or secondary CPU socket. Verify your SR590's current firmware revision supports the 4114T before installation — Lenovo's ServerProven compatibility database is the authoritative reference.
• Up to 768 GB DDR4 SDRAM per processor: Each 4114T supports six memory channels with up to 768 GB of addressable DDR4. In a dual-socket SR590 configuration that scales to 1.5 TB total system memory — sufficient for in-memory database workloads, large VMS archives with fast-search indexes, or virtualization hosts running memory-heavy guest VMs.
• 20 Logical Processors for Virtualization and Parallel Workloads: Running a hypervisor on the SR590? Twenty logical processors per socket give the vCPU scheduler meaningful headroom. A dual-socket build reaches 40 logical processors — a practical ceiling for mid-tier Hyper-V or VMware deployments without moving to a 4-socket platform.
• UPI Interconnect for Multi-Socket Coherency: Intel UPI (Ultra Path Interconnect) replaces QPI on this generation, delivering higher bandwidth between the two processor sockets in a dual-socket SR590. Cache coherency across sockets stays efficient, which matters when workloads actively share data across NUMA nodes — poorly NUMA-aware applications will still suffer, but the interconnect itself is not the bottleneck.
• 64-Bit Operating Mode, 14nm Skylake-SP: Full 64-bit instruction set support covers all current server operating systems and hypervisors. The 14nm process node is mature and thermally well-characterized — silicon binning on this generation is stable, and sustained clock behavior under load is predictable, unlike early production nodes.

Integration and Compatibility

The 4XG7A09076 is designed and validated for the Lenovo ThinkSystem SR590. Lenovo's ServerProven program is the definitive compatibility gate — confirm the SR590 chassis firmware and UEFI version before ordering a second CPU for a previously single-socket build, as some SR590 configurations ship with a CPU2 socket filler that must be removed and the motherboard may require a UEFI update to activate the second socket. The DDR4 SDRAM memory subsystem on the 4114T is compatible with standard RDIMM and LRDIMM DDR4 modules validated for the SR590 platform; mixing DIMM types across sockets is not supported by the memory controller.

For enterprise VMS and NVR server builds running platforms such as Milestone XProtect, Genetec Security Center, or Avigilon Control Center on a Lenovo SR590, the 10-core / 20-thread profile of this processor comfortably handles concurrent decode and analytics processing across 32–64 camera streams depending on resolution and codec, when paired with adequate GPU offload or a software-defined codec pipeline. Storage throughput on the SR590 is the more common bottleneck in these builds — ensure your NVMe or SAS/SATA backplane is sized for the target recording bitrate before assuming CPU is the constraint. Refer to a server selection guide for workload sizing methodology.

Frequently Asked Questions

Q: Is the Lenovo 4XG7A09076 compatible with servers other than the ThinkSystem SR590?

A: The 4XG7A09076 is validated by Lenovo for the ThinkSystem SR590 platform. While the Intel Xeon Silver 4114T uses the standard LGA 3647 socket found on other Skylake-SP platforms, Lenovo option kits are firmware- and thermally validated for specific chassis. Installing in a different server chassis is not supported by Lenovo and may result in thermal or firmware compatibility issues. Always verify via Lenovo ServerProven before substituting.

Q: What is the difference between the Xeon Silver 4114T and the standard Xeon Silver 4114?

A: The 'T' suffix designates the thermally optimized variant. The 4114T runs at 85W TDP versus the standard 4114's 105W, while retaining the same 10-core / 20-thread count and 2.2 GHz base frequency. The lower TDP makes it appropriate for high-density server deployments with tighter power or cooling budgets.

Q: How much memory can the 4XG7A09076 support?

A: The Intel Xeon Silver 4114T supports up to 768 GB of DDR4 SDRAM per processor socket. In a dual-socket ThinkSystem SR590, total addressable memory can reach 1.5 TB, subject to the SR590's DIMM slot count and validated DIMM configurations.

Q: Does this processor support virtualization workloads?

A: Yes. The 4114T's 20 logical processors (10 cores with Hyper-Threading), 64-bit instruction set, and Intel VT-x support make it suitable for hypervisor deployments on the SR590, including VMware vSphere and Microsoft Hyper-V. Check your hypervisor vendor's hardware compatibility list for the specific SR590 configuration.

Q: Is the 4XG7A09076 a genuine Lenovo part?

A: Yes. This is a factory-new, genuine Lenovo processor option kit sourced through US distribution channels — no grey-market, no parallel imports.

Q: What is the boost clock frequency of the Xeon Silver 4114T in this kit?

A: The Intel Xeon Silver 4114T in the 4XG7A09076 reaches a maximum single-core boost frequency of 3.0 GHz, up from its 2.2 GHz all-core base frequency.

Jerry Tildsen

The 4XG7A09076 is a straightforward but important specification decision: you are choosing the 85W TDP 'T' variant of the Xeon Silver 4114T specifically because your rack or chassis has a thermal or power constraint the standard 105W 4114 cannot satisfy. I see integrators reach for this SKU most often when populating the second CPU socket in a ThinkSystem SR590 that was initially shipped single-socket to hit a budget, then scaled up when the workload — typically a VMS recording server or a dense VM host — outgrew the original single-processor allocation.

Technical Highlights:

• 85W TDP (T-variant): Twenty watts less per socket than the standard 4114 means a dual-socket SR590 draws 40W less at peak CPU load. At data center power rates and across a 10-rack deployment, that delta compounds into real operating cost savings over a 3–5 year server lifecycle.
• 10 Cores / 20 Threads, 3.0 GHz Boost: The all-core base of 2.2 GHz is honest for sustained parallel throughput; the 3.0 GHz boost handles the latency-sensitive single-threaded bursts that VMS indexing and database query compilation generate. You get predictable baseline performance without clock throttling under sustained load.
• 768 GB DDR4 per Socket: Six memory channels with up to 768 GB addressable per socket is generous for a Silver-tier processor. A dual-socket SR590 with this CPU can support large in-memory datasets — relevant for Genetec or Milestone installations running forensic search indexes directly in RAM.

Deployment Considerations:

• If this is populating a previously single-socket SR590, the chassis ships with a CPU2 socket filler and a blank DIMM slot configuration. You will need to add matched DDR4 DIMMs to the CPU2 channels simultaneously — the 4114T's six-channel controller expects balanced population for rated throughput. An asymmetric DIMM install will reduce effective memory bandwidth on the second socket.
• Verify the SR590's UEFI firmware version supports the 4114T before installation. Lenovo periodically releases firmware updates that expand processor compatibility on existing platforms; running an older UEFI against a newer CPU stepping can result in POST failures or undeclocked operation.

This SKU is the right choice for a ThinkSystem SR590 being deployed as a VMS recording and analytics server in a thermally dense rack environment where the 20W-per-socket savings of the T-variant are a real operational factor — not just a paper spec.
