FAQs

Q: Which HPE server platforms is the Xeon 6788P compatible with?
A: The Intel Xeon 6788P (P73838-B21) is optimised for HPE ProLiant Gen12 server platforms that support the FCLGA4710 socket. Always verify compatibility with your specific ProLiant model via the HPE Compatibility Matrix before ordering.

Q: Can the Xeon 6788P be used in a multi-processor configuration?
A: Yes. The Xeon 6788P supports up to 4-socket (4S) and 8-socket (8S) multi-processor configurations, making it suitable for large-scale enterprise virtualisation, HPC, and data analytics environments that require high core counts and memory bandwidth across multiple nodes.

Q: What memory does the Xeon 6788P support?
A: The processor supports DDR5 memory at speeds up to 6400 MT/s across 8 memory channels, with a maximum system memory capacity of 4TB. ECC memory is supported to ensure data integrity in mission-critical deployments.

Q: Is the Xeon 6788P suitable for AI and virtualisation workloads?
A: Yes. With 86 Performance Cores, PCIe 5.0 with 88 lanes, and high DDR5 memory bandwidth, the Xeon 6788P is well suited to enterprise virtualisation, cloud computing, real-time analytics, and AI inference workloads.

Q: Can I purchase the HPE Xeon 6788P (P73838-B21) in Australia through IP Trading?
A: Yes. IP Trading (iptrading.com.au) stocks the P73838-B21 and ships Australia-wide. The processor includes a 1-year HPE parts replacement warranty. Contact our team for volume pricing, lead times, or technical pre-sales advice.

Q: What is the difference between the HPE part number P73838-B21 and spare part P78700-001?
A: P73838-B21 is the standard HPE option kit part number used when ordering through HPE or authorised resellers. P78700-001 is the HPE spare part number used for warranty replacements and field spares. Both refer to the same Intel Xeon 6788P processor.
