HPE INT Xeon-g 6526Y CPU for HPE OEM - P67822-B21

HPE P67822-B21 Xeon Gold 6526Y 16-Core Server Processor Upgrade

Overview

The HPE P67822-B21 is an OEM processor upgrade kit delivering Intel's 5th Gen Xeon Gold 6526Y into HPE server platforms that require a factory-validated CPU option. The 6526Y runs 16 cores and 32 threads at a 2.80 GHz base clock, boosting to 3.90 GHz under single-thread load — covering compute-intensive workloads like server infrastructure and virtualized environments without pushing into the higher TDP tiers. At 195W TDP, it fits HPE chassis power and cooling designs validated for this socket class. The 37.50 MB L3 cache supports thread-heavy workloads where data re-use matters, and DDR5-5200 (PC5-41600) memory support means bandwidth is not the bottleneck — relevant when provisioning high-channel-count NVR or edge analytics servers that depend on fast memory throughput. Maximum supported memory reaches 4 TB, giving significant headroom for memory-mapped workloads or large VM deployments. Intel Virtualization Technology (VT-x) is included, a baseline requirement for any hypervisor-based infrastructure deployment.

Compatibility

P67822-B21 is an HPE OEM part keyed to the Socket LGA-4677 platform — the same socket used across HPE ProLiant Gen11 servers built around 5th Gen Intel Xeon Scalable processors. Verify your target server's QuickSpecs document confirms support for the 6526Y SKU specifically; HPE OEM processor upgrades are validated at the platform level and may not be interchangeable across all LGA-4677 systems from other vendors. DDR5-5200/PC5-41600 is the required memory standard — existing DDR4 DIMMs are not compatible with this processor generation. Confirm your chassis power delivery supports the 195W TDP envelope before installing alongside other high-draw components such as high-port-count PoE switches or GPU accelerators sharing the same power domain.

Installation Notes

Processor socket is LGA-4677; standard LGA server installation tooling applies. Thermal specification is rated to 99°C (210.2°F) — ensure HPE-validated heatsink and airflow configuration for the target chassis are in place before commissioning. This is a server processor upgrade intended for HPE OEM platforms; use HPE QuickSpecs to confirm BOM compatibility before ordering. Weight is 1.50 lb as packaged.
