32GB DDR5 4800 ECC RDIMM kit

This kit contains two 16GB DDR5 4800 CL40 1Rx8 registered ECC modules. It runs at 1.1 volts and uses the 288-pin RDIMM form factor. The memory is validated for HP Cray XD220v, XD225v, XD295v and XD670 servers.

Server and workstation upgrades only

Suitable for administrators expanding capacity in the listed HP Cray platforms where registered ECC DDR5 is required. Not suitable for desktop PCs, laptops or consumer motherboards that accept only unbuffered non-ECC memory. Builders needing load-reduced DIMMs or higher-speed grades should look elsewhere.

Sustained operation in registered ECC mode

Registered buffering and on-die ECC maintain data integrity during continuous multi-threaded workloads. The CL40 timing and 1.1V operation are specified for stable throughput at the rated 4800 MT/s speed under prolonged server duty cycles.

Questions sur cet article

Does my HP Cray XD220v need 288-pin DDR5 ECC RDIMM slots to accept this 32GB kit?

Yes, the kit uses 288-pin DDR5 ECC registered DIMMs, which match the slot type on the XD220v, XD225v, XD295v and XD670.

Can I keep my existing DDR5 4800 CL40 ECC registered modules and add this 2x16GB kit?

Yes, provided the installed modules are also 1Rx8 ECC registered DDR5 4800 CL40 at 1.1V; mixing with unbuffered or load-reduced memory is not supported.

How do I verify the kit runs at DDR5 4800 CL40 after installation?

Check the system BIOS or OS memory report; it should show 32GB total at PC5-38400 4800MHz with CL40 timings and 1.1V.
