Capacity and Purpose

This 64GB DDR5 registered DIMM is built for server and workstation platforms that require ECC protection. It targets administrators and integrators who need high-density memory for virtualisation, database or compute workloads.

Critical Specification

The module runs at 4800MHz with a CAS latency of 40 and operates at 1.10V. Its 2Rx4 organisation and registered buffer are the decisive factors for compatibility with qualified DDR5 server boards.

Build Integration

The 288-pin form factor fits standard DDR5 RDIMM slots and the lack of a heat spreader keeps the module height low for dense chassis. It replaces the listed Hynix part numbers directly, freeing procurement from sourcing discontinued OEM modules.

Questions about this item

What real-world bandwidth does the DDR5 4800 (PC5-38400) rating provide?

The DDR5 4800 rating corresponds to PC5-38400, indicating a peak data rate of 4800 MT/s per module when the platform runs at the rated frequency.

Does the 288-pin ECC RDIMM require a registered DIMM slot and registered memory support?

Yes, this is a 288-pin DDR5 RDIMM with ECC and registered buffering; it must be installed in a server or workstation motherboard that supports registered DDR5 memory.

Will the 64 GB module fit in a standard 288-pin DDR5 DIMM slot without a heat spreader?

The module uses the standard 288-pin DDR5 DIMM form factor and has no heat spreader, so it fits any compatible DDR5 RDIMM slot with normal clearance.
