System-Specific DDR5 RDIMM

This OWC 64GB DDR5-4800 CL40 ECC Registered RDIMM is built for HP Cray XD220v, XD225v, XD295v and XD670 servers. It delivers 64GB per module at PC5-38400 speed with a 2Rx4 rank structure and 1.1V operation. The 288-pin form factor fits the validated memory slots in these specific platforms. OWC tests every module in-house to meet JEDEC and RoHS standards.

Suited for HP Cray server upgrades

Administrators expanding memory in the listed HP Cray models will find a direct replacement for part numbers P43331-B21, P46970-H21, P50312-B21, P58358-H21 and P62604-B21. Builders of standard desktops or workstations requiring unbuffered or load-reduced DIMMs cannot use this registered ECC module. Systems that do not support DDR5 RDIMM architecture must look elsewhere for compatible memory.

Registered ECC DDR5 at 4800 MT/s

The defining specification is DDR5-4800 registered ECC with CL40 latency in a 2Rx4 64GB density. This combination determines whether the module will initialise and operate correctly in the target HP Cray XD220v, XD225v, XD295v or XD670 platforms. Verify the server memory configurator requires registered ECC RDIMMs before ordering.

Klausimai apie šią prekę

What slot type and pin count does this 64GB DDR5 module require?

It uses a standard 288-pin DDR5 RDIMM slot, the same form factor used in the HP Cray XD220v, XD225v, XD295v and XD670 servers.

What is the correct installation sequence for this registered ECC DIMM?

Power down the server, open the chassis, align the notch on the 288-pin module with the slot key, press firmly until both retention clips click, then populate channels per the HP Cray service guide.

When should this 2Rx4 ECC registered module be replaced?

Replace it if the system logs uncorrectable ECC errors, fails memory diagnostics, or when upgrading capacity beyond the current 64GB per DIMM configuration.
