Lenovo 4XG7A38081 Intel Xeon Gold 6230R 26-Core Server Processor Option

Overview

The Lenovo 4XG7A38081 is a factory-new processor option kit delivering Intel's 2nd Generation Xeon Gold 6230R — a 26-core, 52-thread Cascade Lake processor — purpose-built for the ThinkSystem SR590 and SR650 platforms. At 2.1 GHz base with a 4.0 GHz Turbo Boost ceiling and a 35.75 MB L3 cache, this is a CPU designed for compute-dense rack deployments where thread count and sustained clock speed both matter: dense virtualization hosts, AI inference workloads, analytics pipelines, and video processing backends where you're running dozens of parallel tasks per socket. For teams expanding a Lenovo Lenovo server infrastructure or refreshing an SR590/SR650 node to a second-socket configuration, this is the OEM-matched option kit to do it correctly.

Key Features

• 26 Cores / 52 Threads (Cascade Lake): At 52 simultaneous threads per socket, this processor handles dense VM consolidation without contention — a dual-socket SR650 configuration reaches 104 threads, meaningful for environments running 40+ VMs per host without overcommitting CPU cycles per guest.
• 2.1 GHz Base / 4.0 GHz Turbo Boost: The 1.9 GHz spread between base and boost gives the scheduler headroom to burst single-threaded tasks (database queries, compile jobs) to 4.0 GHz while keeping multi-threaded sustained workloads at the rated 2.1 GHz — no thermal surprises mid-shift on a 24/7 production node.
• 35.75 MB L3 Cache: A 35.75 MB last-level cache significantly reduces main memory round-trips for working sets that fit — relevant for in-memory databases, analytics engines, and video frame buffers where cache misses become the primary latency bottleneck at scale.
• 150W TDP — Balanced for Dense Racks: At 150W, the 6230R fits within the thermal envelope of the SR590 and SR650 cooling subsystems without requiring supplemental airflow modifications. Compare this against higher-core-count Platinum SKUs that push 205W+ — the 150W ceiling matters when you're calculating per-U power draw across a full rack in a constrained datacenter.
• LGA 3647 (Socket P) — Dual-Socket Ready: Socket P supports dual-socket configurations on the SR650, doubling core count and memory bandwidth per node. If your workload has outgrown single-socket capacity, this option kit is the correct path to scale within the existing chassis rather than provisioning a second server.
• Up to 1 TB Max Memory Support: The 6230R's memory controller supports up to 1 TB of DDR4 RAM per socket — critical for in-memory analytics platforms, large-dataset ML inference, or ERP workloads that page-fault constantly on memory-constrained nodes.
• 52 Threads / 14nm Lithography: Built on Intel's 14nm Cascade Lake process, this generation brought hardware mitigations for Spectre/Meltdown directly into silicon — reducing the performance penalty of software-only mitigations that hit earlier Skylake-SP deployments hard in virtualized environments.
• 64-Bit Operating Mode: Full 64-bit support is table stakes for any modern server and storage workload, but worth confirming for legacy application stacks being migrated to updated infrastructure.

Integration & Compatibility

The 4XG7A38081 is qualified specifically for the ThinkSystem SR590 and SR650 — Lenovo's 2U dual-socket rack servers. Installing this processor into any other platform is unsupported and may result in POST failures or throttled operation. Lenovo's OEM option kit format ensures the processor ships with the appropriate documentation and tracking for warranty alignment with the host server. A compatible heatsink is required and sold separately — this kit does not include a cooler, so factor that into your BOM before ordering. Pair this with compatible DDR4 RDIMMs or LRDIMMs appropriate for your memory capacity target; consult the SR590/SR650 product guide for validated DIMM configurations at your target speed. For teams managing mixed rack server environments, verify firmware levels on the target system match Lenovo's processor compatibility matrix before installation.

Frequently Asked Questions

Q: Which Lenovo servers is the 4XG7A38081 compatible with?

A: The 4XG7A38081 is qualified for the Lenovo ThinkSystem SR590 and SR650 servers only. It is not supported in other ThinkSystem or ThinkServer platforms.

Q: Does the 4XG7A38081 include a heatsink or cooler?

A: No. This is a processor-only option kit — no cooler is included. A compatible heatsink must be purchased separately and installed prior to powering on the server.

Q: What is the TDP of the Intel Xeon Gold 6230R in this kit?

A: The processor has a Thermal Design Power (TDP) of 150W, which is within the rated cooling capacity of the SR590 and SR650 platforms.

Q: How many cores and threads does this processor provide?

A: The Intel Xeon Gold 6230R delivers 26 physical cores and 52 threads via Intel Hyper-Threading, operating in full 64-bit mode.

Q: What is the maximum memory this processor supports?

A: The 6230R supports up to 1 TB of internal memory per socket, subject to the validated DIMM configurations listed in the SR590/SR650 product guide.

Q: What generation is the Intel Xeon Gold 6230R?

A: It is a 2nd Generation Intel Xeon Scalable processor (codename Cascade Lake), built on 14nm lithography with hardware-level mitigations for known side-channel vulnerabilities.

The 4XG7A38081 puts a 26-core, 52-thread Cascade Lake processor into your SR590 or SR650 at a 150W TDP — which is the number I'd focus on first if you're planning a dense rack. You get a meaningful core count without blowing past the thermal and power headroom that Lenovo engineered into these 2U platforms, and the 4.0 GHz Turbo ceiling means latency-sensitive workloads won't stall waiting for a clock boost.

Technical Highlights:

• 26 Cores / 52 Threads: In a dual-socket SR650, you're at 104 threads per node — enough to run aggressive VM density ratios without CPU wait becoming a visible bottleneck in hypervisor dashboards.
• 4.0 GHz Turbo Boost: The 1.9 GHz spread from base (2.1 GHz) to boost (4.0 GHz) is one of the larger deltas in the Xeon Gold 6000R family, giving the OS scheduler genuine headroom for bursty single-threaded tasks without separate CPU allocation.
• 35.75 MB L3 Cache: For workloads like in-memory analytics or video frame processing where working sets are 20–30 MB, keeping data in L3 rather than hitting DDR4 latency is the difference between sub-millisecond and multi-millisecond response times at sustained load.

Deployment Considerations:

• No cooler is in the box — confirm your SR590/SR650 chassis has the correct heatsink for a second-socket installation before this processor arrives. Lenovo's configuration guide specifies heatsink part numbers by thermal zone.
• At 150W per socket, dual-socket SR650 nodes draw 300W in CPU TDP alone at sustained full load; budget PDU and UPS capacity accordingly when filling a rack with dual-socket nodes.

This processor option makes the most sense for teams scaling a Lenovo SR650-based virtualization cluster — particularly where the existing single-socket node is running above 60% CPU utilization and adding a second socket is a cheaper path to headroom than standing up a new server.
