64GB DDR5 4800 ECC RDIMM kit

This 64GB kit contains two 32GB DDR5 4800 CL40 registered ECC modules built for HP Cray XD220v, XD225v, XD295v and XD670 servers. It targets administrators expanding memory in those specific platforms where registered ECC DDR5 is required. The modules run at 1.1V and conform to JEDEC PC5-38400 standards. They are not compatible with standard desktop systems or unbuffered memory configurations.

Capacity and headroom for server workloads

The 64GB total capacity adds significant headroom for virtualisation, database caching and large dataset processing on the listed Cray models. Each 32GB 2Rx8 module fills a single 288-pin slot, allowing further expansion up to the platform's maximum supported capacity. Workloads that exceed this kit's capacity will require additional registered ECC modules of the same specification; mixing with unbuffered or load-reduced DIMMs is not supported.

Thermals and power draw in normal use

Operating at 1.1V without heat spreaders, the modules rely on the server's directed airflow for cooling. Registered ECC DDR5 at this voltage typically maintains low power draw per DIMM under sustained load, keeping thermal contribution minimal in a properly ventilated chassis. Acoustic impact is negligible as the modules have no moving parts and depend entirely on system fans.

أسئلة حول هذا المنتج

Will the 2Rx8 registered DDR5 4800 modules work with any unbuffered memory already installed in my HP Cray XD225v?

No, registered DIMMs cannot be mixed with unbuffered or load-reduced memory; all slots must use registered ECC modules for the system to operate correctly.

How can I confirm the 64 GB kit is running at DDR5 4800 CL40 after installation?

Check the BIOS memory information or a tool such as dmidecode; it should report 4800 MT/s, CAS latency 40, 1.1 V, ECC registered, and 2Rx8 organisation for each 32 GB module.

Does the 2 x 32 GB kit include any heat spreaders or extra cables, or must I buy them separately?

The modules ship without heat spreaders and no cables are included or required; the kit contains only the two 288-pin RDIMMs.
