Lenovo 4XG7A63078 SD530 Xeon Gold 6240R

Lenovo 4XG7A63078 Intel Xeon Gold 6240R Processor Option Kit

Overview

The Lenovo 4XG7A63078 is a factory-configured processor option kit delivering the Intel Xeon Gold 6240R for use in Lenovo ThinkSystem SD530 dense compute nodes. With 24 physical cores clocked at 2.4 GHz base and a 4 GHz single-core boost, this 2nd Generation Intel Xeon Scalable (Cascade Lake) processor targets workloads where thread count and memory bandwidth matter — virtualization hosts, video analytics servers, distributed storage nodes, and high-density rack deployments where you're trying to maximize compute density per U of space. If you're specifying a Lenovo SD530 and need a processor that can run 48 concurrent threads without throttling under sustained load, the 4XG7A63078 is the correct line item.

Key Features

• 24 Cores / 48 Threads at 2.4 GHz Base: The Xeon Gold 6240R runs 48 simultaneous threads, which is the practical number that matters for hypervisor scheduling on VMware ESXi or Hyper-V. A dual-socket SD530 node populated with two of these hits 96 threads — meaningful headroom for consolidating workloads that previously required separate physical servers.
• 4 GHz Single-Core Boost (Cascade Lake): The 4 GHz Turbo Boost ceiling handles bursty, latency-sensitive jobs — database query execution, VMS motion analytics, or compilation tasks — without requiring you to overprovision base clock. You get high thread density and responsive peak performance from the same die.
• 35.75 MB L3 Cache: Nearly 36 MB of last-level cache reduces main memory round-trips on in-flight datasets. For video analytics workloads processing multiple high-resolution streams simultaneously, a larger cache measurably reduces latency spikes compared to lower-tier Xeon Silver options with roughly half the cache.
• 165 W TDP — Plan Your Thermal Budget: At 165 W, this processor draws more than mid-range Xeon Gold options. In a dense SD530 chassis, thermal headroom per node matters. Verify your rack cooling capacity before populating multi-node SD530 shelves at full processor density — this is not a passive-cooling scenario.
• Up to 1 TB DDR4-2933 Memory per Socket: Support for 1 TB of DDR4 RAM per processor socket means an SD530 node can be configured with substantial in-memory capacity for databases, in-memory caches, or large VM workloads — at 2933 MHz, the memory bandwidth keeps pace with the core count without creating a bottleneck on memory-intensive applications.
• LGA 3647 (Socket P) — SD530-Specific: This is a platform-specific option kit. The LGA 3647 socket is exclusive to Intel's Purley platform (Skylake-SP and Cascade Lake-SP), which means the 4XG7A63078 installs only into compatible Lenovo ThinkSystem SD530 nodes. It is not interchangeable with consumer or workstation sockets.
• UPI Interconnect — Multi-Socket Coherency: Intel Ultra Path Interconnect (UPI) handles processor-to-processor communication in dual-socket SD530 configurations without a separate front-side bus. For workloads that span both sockets — large VMs, NUMA-aware applications — UPI keeps cache coherency overhead manageable.
• 64-bit Architecture, 14 nm Fabrication: Cascade Lake's 14 nm++ lithography is a mature, well-characterized process node. The absence of the power and yield surprises that affected early 10 nm parts makes these processors predictable in production — relevant when you're planning a multi-node deployment and need consistent thermal and performance behavior across units.

Integration and Compatibility

The 4XG7A63078 is designed for the Lenovo ThinkSystem SD530 compute node and requires a compatible SD530 chassis. Confirm your SD530 firmware revision supports 2nd Generation Intel Xeon Scalable processors before ordering — some early SD530 chassis shipped with firmware targeting 1st Gen Skylake-SP and require a BIOS update prior to installing Cascade Lake CPUs. Memory compatibility should be validated against Lenovo's ServerProven list for the SD530; DDR4-2933 DIMMs are required to reach the processor's rated memory speed. For Lenovo's broader Lenovo server and compute catalog, verify socket and platform compatibility per node model before substituting processors across chassis generations.

Buyers specifying compute for enterprise deployments should also evaluate servers and storage options alongside processor kits to ensure chassis, processor, memory, and storage are sourced as a validated configuration. For guidance on matching processor TDP to rack power distribution, review available power and UPS infrastructure options to confirm per-rack power budget.

Frequently Asked Questions

Q: Is the Lenovo 4XG7A63078 compatible with servers other than the SD530?

A: The 4XG7A63078 is a Lenovo-configured option kit for the ThinkSystem SD530. While the underlying Intel Xeon Gold 6240R uses the LGA 3647 (Socket P) socket found in several Intel Purley-platform servers, this specific part number is a Lenovo OEM kit validated for SD530 use. Always verify compatibility against Lenovo's ServerProven list for any specific chassis before ordering.

Q: How many cores and threads does the Xeon Gold 6240R provide?

A: The Intel Xeon Gold 6240R provides 24 physical cores and 48 threads via Intel Hyper-Threading. This makes it suitable for virtualization hosts, analytics servers, and multi-threaded workloads where high thread density is required.

Q: What is the maximum memory supported by the 4XG7A63078?

A: The Intel Xeon Gold 6240R supports up to 1 TB of DDR4-SDRAM per processor socket at speeds up to 2933 MHz. In a dual-socket SD530 configuration, total system memory can reach 2 TB, depending on DIMM slot count and chassis support.

Q: What is the thermal design power (TDP) of this processor?

A: The Xeon Gold 6240R has a TDP of 165 W. Ensure your SD530 chassis and rack cooling infrastructure are rated to handle this thermal output, particularly in high-density multi-node deployments.

Q: What is the processor boost frequency?

A: The Xeon Gold 6240R has a base frequency of 2.4 GHz and a maximum Turbo Boost frequency of 4 GHz. The boost frequency applies to single-core workloads under favorable thermal and power conditions.

Q: Does this processor support 64-bit operating systems?

A: Yes. The Intel Xeon Gold 6240R operates in 64-bit mode and is compatible with 64-bit operating systems including Windows Server, Red Hat Enterprise Linux, SUSE Linux Enterprise Server, and VMware ESXi.

Karl Wilson

The 4XG7A63078 is a straightforward specification decision when you're building out SD530 nodes for high-density compute: the Xeon Gold 6240R's 24-core / 48-thread configuration at 2.4 GHz base with a 4 GHz boost hits the practical sweet spot between core density and per-core performance for the workloads these nodes typically run. What I look at first is the 165 W TDP — that's the spec that drives rack planning, not the GHz number.

Technical Highlights:

• 48 Threads per Socket: In a dual-socket SD530, you reach 96 hardware threads — enough to consolidate 20–30 moderately sized VMs without fighting for scheduler slots, which directly reduces the number of physical nodes you need in a high-density deployment.
• 4 GHz Turbo Boost: The jump from 2.4 GHz base to 4 GHz peak matters for latency-sensitive operations — VMS analytics engines, database query execution, real-time stream processing — where waiting on a slow single-threaded phase is the actual bottleneck.
• 35.75 MB L3 Cache + DDR4-2933: The cache-to-core ratio on the 6240R is generous, and pairing it with 2933 MHz DDR4 avoids the memory bandwidth cliff that some high-core-count Xeon parts run into when all 24 cores are active simultaneously.

Deployment Considerations:

• At 165 W TDP, verify that your SD530 chassis firmware is current before installation — early SD530 BIOS revisions targeted 1st Gen Skylake-SP and may not correctly report or manage Cascade Lake thermal states, which can cause unexpected throttling under sustained load.
• This is a platform-locked option kit. LGA 3647 is the correct socket, but the Lenovo OEM packaging means you should not expect cross-chassis compatibility outside the SD530 product line without explicit Lenovo ServerProven validation.

For dense virtualization racks where you're running 20+ VMs per node and need predictable thermal behavior across a multi-node deployment, the 4XG7A63078 in a dual-socket SD530 configuration is a solid build — the thread count and memory capacity headroom will keep the nodes viable through multiple hypervisor generation upgrades before the hardware becomes the constraint.
