Unlock unprecedented multi-core performance for data centers, virtualization, and HPC workloads with the HPE Intel Xeon Platinum (5th Gen) 8558P Octatetraconta-core processor upgrade. Boasting 48 cores and 96 threads, this Enterprise-grade CPU is designed to boost throughput, accelerate parallel tasks, and deliver reliable, scalable performance on compatible HP platforms. With a 260 MB L3 cache, a base clock of 2.70 GHz, and a turbo capability that reaches up to 4.0 GHz, it’s built to handle the most demanding workloads while maintaining efficiency in modern server environments. The LGA-4677 socket and 350 W thermal design power (TDP) support robust cooling and sustained performance, ensuring smooth operation in mission-critical applications. Optimized for 64-bit processing and engineered for high-density data centers, this upgrade is a strategic choice for organizations pursuing cloud, virtualization, and analytics acceleration on HP servers.

  • Blazing multi-core performance for virtualization and data-intensive workloads: With 48 cores and 96 threads, the 8558P is engineered to execute highly parallel workloads with exceptional throughput. This makes it ideal for dense virtualized environments, large-scale databases, and HPC simulations where thread-level parallelism translates directly into faster service delivery and improved resource utilization.
  • Massive cache and data throughput for low latency: The processor features a substantial 260 MB L3 cache, designed to dramatically reduce memory latency and improve data reuse. This large cache footprint helps boost real-time analytics, in-memory databases, and streaming workloads by keeping frequently accessed data close to the processing cores.
  • High clock speeds with authoritative turbo performance: A base clock of 2.70 GHz is complemented by a turbo capability up to 4.0 GHz, delivering bursts of performance when single-threaded or lightly-threaded tasks demand faster clocks. This combination ensures strong performance for a wide range of enterprise workloads, from transactional processing to complex simulations.
  • Enterprise-grade platform compatibility and reliability: Built for Socket LGA-4677 and designed to upgrade HPE servers, this processor aligns with enterprise requirements for reliability, stability, and scalable growth. The 350 W TDP supports robust cooling and sustained operation in dense server configurations, enabling long-term workloads without compromise.
  • 64-bit processing and scalable multi-threaded performance: As a 64-bit-capable Xeon Platinum processor, the 8558P delivers modern computing efficiency, advanced security features, and robust support for large address spaces. Coupled with 96 threads, this CPU is well-suited for virtualization, cloud workloads, analytics pipelines, and data-centric applications that demand consistent, scalable performance across cores.

How to install HPE Intel Xeon Platinum 8558P Octatetraconta-core Processor Upgrade

  • Prepare the server and verify compatibility: Confirm that your HP server motherboard supports the LGA-4677 socket and that the BIOS/firmware is compatible with Intel Xeon Platinum 5th Gen processors. Check HP’s hardware compatibility guides and ensure you have the proper cooling solution capable of handling a 350 W TDP part.
  • Power down and ground yourself: Shut down the server, unplug all power sources, and discharge static from your body or workstation using an anti-static strap to protect sensitive components.
  • Access the CPU socket and remove the existing processor: Open the CPU socket lever, carefully lift the heatsink if present, and remove the current processor while keeping the socket pins or land patterns undamaged. Inspect for any bent pins or debris and clean as needed following the manufacturer’s guidelines.
  • Install the new processor: Align the 8558P with the socket using the alignment notches and seating grooves. Gently lower the CPU into the socket, ensuring even contact. Secure the socket lever to lock the processor in place, following the server’s service manual for proper torque and seating.
  • Apply cooling and thermal interface material if required: Install an appropriate server-grade heatsink/cooler and apply a thin, even layer of thermal interface material as recommended by the cooling solution’s manufacturer. Ensure proper clearance and airflow to manage the 350 W TDP effectively.
  • Update firmware and BIOS: Power on the server and enter BIOS/UEFI to verify CPU recognition. Install any recommended microcode updates, BIOS patches, and firmware updates to ensure full compatibility and optimization for the 8558P.
  • Test and validate: Boot into the operating system and perform a basic stability check. Run stress tests and monitor CPU temperatures and power consumption to confirm stable operation under load. Validate that virtualization, databases, or HPC workloads run as expected.

Great quality, better than a rental.
Size: 4X-Large, Color: Navy Blue, Size: 4X-Large, Color: Navy Blue
This suit was a pleasant surprise in quality! Just note, sizing isn’t perfect since it’s a set, so the pants were really long and the waist slightly bigger than my husband’s actual size, as we had to fit for his chest and shoulders. However, we were able to hem the pants quite easily and he just wore a belt which worked perfectly. For the price and quality you receive, well worth it. We ended up using a different tie than given so it would match my dress. Worth every cent even if worn once since rentals are way more expense. This held up for a full 8hrs of schmoozing and dancing and is still in great shape.
