Lenovo 4XG7A09055 SR530 Xeon 6128 6C/115W/3.4GHZ

Lenovo 4XG7A09055 Xeon Gold 6128 6-Core Processor for ThinkSystem SR530

Overview

The Lenovo 4XG7A09055 is a factory-new Intel Xeon Gold 6128 processor option for the ThinkSystem SR530 server platform — a 6-core, 12-thread Skylake-generation chip running at 3.4 GHz base with 3.7 GHz Turbo Boost. If you're scaling a server workload that demands single-threaded headroom over raw core density — think per-socket-licensed software, latency-sensitive databases, or physical security analytics engines — the 6128's high clock rate and Intel Xeon Gold architecture make it the right fit over lower-frequency many-core options. At 115W TDP, it sits in the mid-range thermal envelope for the SR530 chassis, manageable for standard rack cooling without exotic airflow design.

Key Features

• 3.4 GHz Base / 3.7 GHz Turbo: The 6128 prioritizes clock speed over thread count — useful when workloads are per-core-licensed (Oracle DB, SQL Server Standard Edition) or when per-thread latency matters more than parallelism. The 300 MHz Turbo headroom engages automatically on lightly threaded bursts without manual configuration.
• 6 Cores / 12 Threads: Twelve logical processors on a 6-core die gives you enough parallelism for mid-size virtualization stacks, security management servers, or multi-stream video analytics without the licensing cost of scaling to 8- or 12-core SKUs. This is the sensible middle ground for single-socket SR530 deployments under moderate concurrent workload.
• 19.25 MB L3 Cache: A large shared L3 cache (roughly 3.2 MB per core) reduces memory latency on working sets that fit in cache — relevant for in-memory database caching, VMS index lookups, or real-time access control event processing where repeated data access is the norm.
• 115W TDP: The cooler is included with this kit, which matters for SR530 configurations where the processor option is ordered separately from the base server. At 115W, it fits standard SR530 thermal design without requiring upgraded fans or chassis airflow modifications — verify your specific SR530 chassis airflow configuration for dual-processor deployments.
• 768 GB Maximum Memory Support: The 6128 supports up to 768 GB of RAM across the SR530's memory channels — enough headroom for memory-intensive workloads like in-memory analytics, large VMS databases, or hypervisor-heavy environments consolidating dozens of virtual machines.
• LGA 3647 (Socket P) / 1st Gen Xeon Scalable: Designed for the Skylake-SP platform, this processor fits SR530 boards provisioned for 1st Generation Intel Xeon Scalable. Confirm your SR530 firmware and board revision support the H0 stepping before deployment — mixed-generation or 2nd-Gen Cascade Lake boards require a different processor family.
• 14nm Skylake Architecture: The Skylake-SP microarchitecture underpins this generation's AVX-512 instruction support and memory bandwidth improvements over Broadwell. For workloads that leverage vectorized compute — scientific computing, certain analytics pipelines, or media transcoding — AVX-512 availability at this clock rate is a meaningful platform capability.
• 64-bit / 12 Operating Threads: Full 64-bit support with 12 hardware threads means the processor can handle concurrent OS, hypervisor, and application workloads without context-switch pressure. For a network video recorder server or physical security management platform, this translates to stable concurrent stream handling without CPU contention between the OS and the application layer.

Integration and Compatibility

The 4XG7A09055 is a Lenovo option part engineered specifically for the ThinkSystem SR530 server. It installs into the LGA 3647 Socket P on SR530 motherboards validated for 1st Generation Intel Xeon Scalable processors. Pair with compatible DDR4 RDIMM or LRDIMM memory options for the SR530 platform — the 6128 supports six memory channels, so maximizing channel population is key to extracting full memory bandwidth for data-intensive workloads.

For organizations running physical security infrastructure — including IP camera management servers, access control backends, or centralized VMS platforms — the SR530 with this processor delivers a stable, commercially-supported compute foundation. The Xeon Gold class also supports Intel vPro and out-of-band management features relevant for network-connected enterprise server environments where remote management without physical access is a requirement.

Frequently Asked Questions

Q: Is the Lenovo 4XG7A09055 compatible with ThinkSystem SR530 servers?

A: Yes. The 4XG7A09055 is a Lenovo option part designed for the ThinkSystem SR530 platform. It uses the LGA 3647 (Socket P) interface and is validated for SR530 motherboards supporting 1st Generation Intel Xeon Scalable processors.

Q: Does the 4XG7A09055 include a cooler?

A: Yes. A cooler is included with the 4XG7A09055 processor kit, which is important when ordering processor options separately from the SR530 base server configuration.

Q: What is the TDP of the Xeon Gold 6128 in the 4XG7A09055?

A: The Xeon Gold 6128 has a Thermal Design Power (TDP) of 115W. This falls within the standard SR530 thermal envelope, though dual-processor configurations should verify chassis airflow specifications.

Q: How many cores and threads does the 4XG7A09055 processor provide?

A: The Intel Xeon Gold 6128 delivers 6 physical cores and 12 threads via Intel Hyper-Threading. Base clock is 3.4 GHz with Turbo Boost up to 3.7 GHz.

Q: What is the maximum memory this processor supports?

A: The Xeon Gold 6128 supports up to 768 GB of RAM, giving SR530 deployments significant headroom for memory-intensive workloads including large VMS databases and virtualization stacks.

Q: Will this processor work in a 2nd Generation Xeon Scalable (Cascade Lake) SR530 configuration?

A: No. The 4XG7A09055 is a 1st Generation Xeon Scalable (Skylake-SP, H0 stepping) processor. It is not compatible with SR530 boards configured for 2nd Generation Cascade Lake processors. Verify your SR530 board revision and firmware before ordering.

Karl Wilson

The 4XG7A09055 is one of those processor options that fits a specific deployment profile precisely — and gets overshadowed when buyers default to higher core counts without thinking through their workload. The Xeon Gold 6128's 3.4 GHz base clock (boosting to 3.7 GHz) is the highest base frequency available in the 6-core bracket of the 1st Gen Scalable family, which matters a lot when you're running per-core-licensed software or a security management platform where thread latency directly affects event throughput.

Technical Highlights:

• 3.4 GHz / 3.7 GHz Turbo: At 6 cores, this clock rate outperforms higher-core-count Gold SKUs for single-threaded and lightly-threaded tasks — relevant for SQL Server Standard, Oracle SE2, or any VMS platform with per-instance licensing that caps usable cores.
• 19.25 MB L3 Cache at 115W TDP: The cache-to-TDP ratio here is efficient. You get a large working set in cache without pushing into the 150W+ thermal bracket that forces fan speed increases and acoustic trade-offs in rack-dense environments.
• 768 GB Max Memory / LGA 3647 Six-Channel: Six memory channels on Socket P mean you can fully populate the SR530's DIMM slots for maximum bandwidth — critical if this server is hosting a large-scale VMS database or multi-tenant hypervisor stack where memory bandwidth is the real bottleneck.

Deployment Considerations:

• The H0 stepping designation is critical for SR530 compatibility validation — confirm the board's UEFI/BIOS firmware level supports this stepping before physical installation, as some early SR530 firmware revisions require an update before recognizing H0 processors.
• Watch out for ordering this alongside 2nd Gen (Cascade Lake) memory options — while the DIMM slots are physically the same, optimal memory speed and RAS features require pairing with memory validated for 1st Gen Scalable on the SR530 platform.

This processor is the right pick for SR530 deployments running commercially-licensed security software stacks — physical security information management (PSIM) platforms, centralized VMS servers, or access control backends — where per-core software licensing makes the 6-core/high-clock profile more cost-effective than a 12- or 16-core lower-frequency alternative.
