Lenovo 4XG7A07260 SR590 Xeon 4108 8C/85W/1.8GHZ

Lenovo 4XG7A07260 Intel Xeon Silver 4108 8-Core Processor Option Kit

Overview

The Lenovo 4XG7A07260 is an Intel Xeon Silver 4108 processor option kit designed for the ThinkSystem SR590 server platform. If you are configuring or expanding an SR590 and need a factory-matched CPU with the correct stepping and thermal solution for that chassis, this is the part to order — not a retail-boxed chip, but an OEM kit sourced and validated for the SR590 bill of materials.

The Xeon Silver 4108 is a first-generation Intel Xeon Scalable (Skylake) processor running 8 cores and 16 threads at a 1.8 GHz base frequency with a 3.0 GHz single-core boost. At 85W TDP, it sits in a middle position within the Scalable family — enough headroom for moderate virtualization or multi-threaded workloads without pushing power budget limits on a dual-socket chassis. The cooler is included in the kit, which matters for SR590 deployments where the correct heatsink is dictated by chassis airflow zone and DIMM population density.

Key Features

• 8 Cores / 16 Threads (Skylake, 14nm): The 4108's 8-core / 16-thread configuration handles parallel workloads — VM hosting, surveillance recording, and analytics offload — without the cost or power draw of higher-tier Gold/Platinum SKUs. Skylake's 14nm lithography is mature and well-characterized for data center thermal envelopes.
• 1.8 GHz Base / 3.0 GHz Boost: The base frequency is conservative for sustained multi-core loads; the 3.0 GHz boost applies to lightly threaded tasks like single-instance database queries or control-plane processes. Plan your workload mix accordingly — if sustained all-core throughput is the priority, the base 1.8 GHz is the working number.
• 11 MB L3 Cache: 11 MB of shared L3 distributes across 8 cores. For surveillance workloads where codec decoding and stream management create frequent small-block memory accesses, this cache depth helps keep latency in check without hitting main memory on every frame decode.
• 85W TDP with Cooler Included: The 85W thermal envelope is manageable for a 2U chassis. The included cooler is specifically selected for SR590 airflow — using a third-party or carry-over heatsink risks throttling in higher-ambient or dense-DIMM configurations. Use the supplied cooler.
• LGA 3647 (Socket P) — First-Gen Scalable Platform: This socket is exclusive to the first-generation Xeon Scalable lineup. Confirm your SR590 board revision supports this stepping (U0) before ordering. It is not forward-compatible with second-gen (Cascade Lake) processors without a firmware and platform change.
• 768 GB Maximum Memory Support: The platform supports up to 768 GB of DDR4 RAM across the SR590's DIMM slots — relevant if you are provisioning a server for large-memory workloads such as in-memory databases, high-channel-count video analytics, or dense VM hosting. The processor itself does not limit you on the memory side within the SR590's channel count.

Integration & Compatibility

The 4XG7A07260 is a ThinkSystem SR590-specific option kit. It targets the LGA 3647 (Socket P) socket on the SR590 motherboard and is paired with Lenovo's server-validated thermal solution. Before installing, verify current firmware versions for the SR590's UEFI and BMC — first-gen Scalable processors on this platform have specific microcode requirements that affect stability and full performance state activation.

For system integrators building out surveillance or video analytics platforms on SR590 infrastructure, this processor pairs with Lenovo's broader Lenovo server and compute catalog. When planning storage and NIC configurations alongside this CPU option, consult the servers and storage category for compatible components. If you are building a surveillance-focused rack, review the network video recorder options and network switching that integrate with server-based VMS deployments. For detailed guidance on matching compute resources to camera channel counts and retention requirements, the surveillance storage planning guide is a useful reference.

Frequently Asked Questions

Q: Is the 4XG7A07260 a drop-in upgrade for any LGA 3647 server, or is it SR590-specific?

A: This part number is validated and kitted specifically for the ThinkSystem SR590. While the Xeon Silver 4108 uses the LGA 3647 socket found on other Scalable platforms, the 4XG7A07260 kit includes the SR590-specific heatsink and is sourced as an SR590 option. Using it in other platforms is not covered by this option kit's validation.

Q: Does the 4XG7A07260 include a heatsink?

A: Yes. The cooler is included in the kit — this is confirmed in the product specifications. The heatsink is matched to the SR590 chassis airflow profile.

Q: What is the processor socket for the 4XG7A07260?

A: LGA 3647, also referred to as Socket P. This is the first-generation Intel Xeon Scalable socket and is not compatible with second-generation (Cascade Lake) processors without a platform change.

Q: What is the maximum RAM the system supports with the 4XG7A07260 installed?

A: The processor supports up to 768 GB of DDR4 memory within the SR590 platform's DIMM slot configuration.

Q: What is the TDP of the Xeon Silver 4108 in the 4XG7A07260?

A: 85W. This is within the SR590's thermal design for standard 2U airflow. Verify chassis configuration and DIMM density if operating in elevated ambient temperatures.

The Lenovo 4XG7A07260 is a purpose-kitted option for SR590 deployments that need a validated first-gen Scalable processor with the correct heatsink in one part number. The Xeon Silver 4108's 85W TDP is the detail I always flag first — it keeps dual-socket SR590 builds well within the chassis power budget, which matters when you are also populating high-density DIMMs and multiple PCIe cards for a surveillance or analytics workload.

Technical Highlights:

• 8C/16T at 85W TDP: Delivers 16 concurrent threads for parallel workloads — codec decoding, stream management, VM processes — at a thermal load the SR590's 2U cooling handles without special configuration.
• 3.0 GHz single-core boost: Lightly-threaded control processes (database queries, API handlers, scheduler tasks) benefit from the boost headroom even on a server running sustained multi-core loads.
• 768 GB platform memory ceiling: With full DIMM population on the SR590, 768 GB of addressable RAM is available — relevant for in-memory analytics or high-channel VMS platforms where frame buffer and index data grows proportionally with camera count.

Deployment Considerations:

• Confirm SR590 UEFI and BMC firmware supports Stepping U0 before installing — running stale microcode on first-gen Scalable platforms can prevent the processor from entering full performance states.
• The 1.8 GHz base frequency is the sustained all-core number; workloads that require consistent high-frequency throughput across all 8 cores may find the Silver 4108 limiting compared to higher-bin Scalable SKUs — size this against your actual multi-threaded workload, not the boost spec.

The 4XG7A07260 is the right choice for SR590-based surveillance recording or mid-tier virtualization platforms where power budget and chassis thermal constraints rule out higher-TDP Gold/Platinum options, and where a factory-matched, cooler-included kit simplifies procurement and build validation.
