Lenovo 4XG7A63284 SR630 Xeon Gold 6242R

Lenovo 4XG7A63284 Intel Xeon Gold 6242R 20-Core Processor Upgrade for ThinkSystem SR630

Overview

The Lenovo 4XG7A63284 is a factory-configured processor option kit that installs the Intel Xeon Gold 6242R into the ThinkSystem SR630 1U rack server. Built on Intel's 2nd Generation Xeon Scalable (Cascade Lake) architecture at 14 nm, the 6242R delivers 20 cores and 40 threads with a 3.1 GHz base clock and a 4.1 GHz maximum Turbo Boost frequency — headroom that matters when workloads spike unpredictably in virtualized or analytics-heavy environments. If you are spec'ing compute for a network video recorder platform, a rack server deployment, or a workstation running edge analytics, this kit slots directly into the SR630's LGA 3647 (Socket P) socket with no additional hardware required beyond what Lenovo specifies for the platform.

Key Features

• 20 Cores / 40 Threads at 3.1–4.1 GHz: The 6242R's 20-core, 40-thread configuration handles heavily parallelized workloads — think concurrent video decode streams, multiple VM guests, or simultaneous analytics inference — without the core-count premium of higher-tier Xeon Platinum parts. The 4.1 GHz Turbo ceiling keeps single-threaded latency tight for database lookups and VMS event correlation.
• 35.75 MB L3 Cache: Nearly 36 MB of last-level cache reduces main-memory round-trips on working sets that fit within it — directly relevant when a VMS is indexing motion metadata or a server is caching frequently accessed records. Less cache pressure means more consistent frame throughput under load.
• 205 W TDP — Plan Your Thermal Budget: At 205 W, the 6242R sits at the upper boundary of what SR630 cooling is validated to handle. Verify your chassis cooling configuration against Lenovo's thermal matrix before ordering. This is not a processor you can drop into a passively cooled or thermally marginal enclosure — dedicated active cooling in the SR630 is non-negotiable at this TDP.
• Up to 1 TB DDR4 Memory Support: The Cascade Lake memory controller supports up to 1 TB of DDR4-SDRAM per socket. For surveillance deployments running in-memory databases or caching large video indexes, that ceiling gives substantial room to grow without replacing the processor. DDR4 also provides better bandwidth-per-watt than previous generations — useful when memory channels are under sustained streaming load.
• LGA 3647 (Socket P) — SR630 Platform Lock-In: The 4XG7A63284 is validated specifically for the ThinkSystem SR630. Socket P is a Lenovo enterprise platform socket; this processor will not install into consumer or workstation boards. If you are not running an SR630, stop here — compatibility is platform-specific, not just socket-specific on Lenovo server products.
• 64-Bit Operating Mode / 40 Logical Processors: Full x86-64 support means every current enterprise OS and hypervisor (VMware ESXi, Windows Server, Red Hat, Ubuntu) runs without mode restrictions. 40 logical processors give a hypervisor substantial vCPU scheduling capacity — a 4-node cluster of SR630s at this spec level can run dozens of concurrent workloads without resource contention.
• Cascade Lake Microarchitecture: Cascade Lake adds hardware-level mitigations for Spectre/Meltdown variants that earlier Skylake-SP Xeons addressed only in software — meaning less microcode overhead and more predictable throughput than first-generation Xeon Scalable at the same core count. For security-sensitive deployments, hardware mitigations are meaningfully preferable to firmware-only patches.

Integration & Compatibility

This processor option is validated for the Lenovo ThinkSystem SR630 server platform. Lenovo publishes a hardware compatibility matrix (ServerProven) that governs which memory DIMMs, PCIe adapters, and storage controllers are validated alongside the 6242R at 205 W TDP — consult it before finalizing your BOM. The 2nd Generation Xeon Scalable platform supports UPI (Ultra Path Interconnect) for dual-socket configurations; if your SR630 is single-socket today, adding a second 4XG7A63284 or a matched processor is the upgrade path. For NVR and video management server builds, pair with validated DDR4 RDIMMs and a supported RAID adapter — Lenovo's platform warranty depends on using ServerProven components. Review your network switching and storage I/O requirements in parallel, since the SR630's PCIe bandwidth is also a ceiling on how many high-throughput NICs or HBAs you can saturate at this compute level.

Frequently Asked Questions

Q: What server platform is the Lenovo 4XG7A63284 compatible with?

A: The 4XG7A63284 is validated for the Lenovo ThinkSystem SR630 server. It uses the LGA 3647 (Socket P) socket and is a platform-specific option kit — it is not a retail-boxed processor and will not install in non-Lenovo or non-SR630 platforms without Lenovo validation.

Q: How many cores and threads does the Xeon Gold 6242R provide?

A: The Intel Xeon Gold 6242R delivers 20 physical cores and 40 threads via Hyper-Threading. Base clock is 3.1 GHz with Turbo Boost up to 4.1 GHz.

Q: What is the TDP of the 6242R, and does the SR630 support it?

A: The Xeon Gold 6242R has a 205 W TDP. The SR630 supports this TDP with the appropriate cooling configuration. Verify against Lenovo's thermal configuration guide for your specific SR630 chassis and cooling kit before installing.

Q: What is the maximum memory this processor supports?

A: The Xeon Gold 6242R supports up to 1 TB of DDR4-SDRAM per socket. The specific DIMM types and speeds supported depend on the SR630 memory configuration and Lenovo's ServerProven validated DIMM list.

Q: Is the 4XG7A63284 a single- or dual-socket upgrade?

A: This kit provides one processor. The SR630 supports dual-socket configurations; a second matched processor (same model or a Lenovo-validated peer) can be added for a two-socket build using UPI interconnect.

Q: What microarchitecture does the Xeon Gold 6242R use?

A: The 6242R is based on Intel's Cascade Lake microarchitecture (2nd Generation Xeon Scalable), fabricated at 14 nm. Cascade Lake includes hardware-level mitigations for Spectre/Meltdown variants, reducing the software overhead associated with first-generation Skylake-SP Xeon processors.

The 4XG7A63284 is one of the higher-TDP options in the SR630 processor lineup — at 205 W, you are getting 20 Cascade Lake cores with a 4.1 GHz Turbo ceiling, which is a meaningful step up from the mid-range Gold 6200-series parts. That TDP figure is the first thing I check when someone asks about dropping this into an existing SR630: the cooling configuration has to be validated for it, and on a 1U chassis there is less thermal margin than engineers sometimes assume.

Technical Highlights:

• 20C/40T at 3.1–4.1 GHz: Strong parallel throughput for concurrent VM workloads, video analytics, or multi-stream transcoding, with enough single-threaded headroom at 4.1 GHz Turbo to keep latency-sensitive tasks responsive.
• 35.75 MB L3 Cache: Near-36 MB of last-level cache is large enough to hold working sets for many VMS indexing and database query patterns, reducing DRAM pressure under sustained load.
• DDR4 up to 1 TB per socket: The 1 TB memory ceiling is relevant for memory-hungry applications like in-memory analytics or large-scale virtualization — you will not hit a processor-side memory wall on the SR630 with this part.

Deployment Considerations:

• Verify your SR630 cooling kit is rated for 205 W TDP before ordering — Lenovo's thermal configuration guide is explicit about which fan and heatsink combinations are required at this power level. Installing without the correct cooling kit voids Lenovo's platform support.
• This is a Lenovo option kit, not a retail-boxed Intel processor. It will not install in non-SR630 Lenovo servers or third-party platforms, even those using LGA 3647 — platform firmware and BIOS validation are specific to the ThinkSystem SR630.

For a security operations center or video analytics server build where the SR630 is running a VMS with concurrent AI inference tasks alongside virtualized management workloads, the 6242R's core count and cache depth make it a logical choice — assuming your thermal and power provisioning is already sized for 205 W continuous draw.
