Server-grade 64GB DDR5 RDIMM

This OWC module delivers 64GB of DDR5 4800 memory in a 288-pin registered DIMM. It operates at 1.1V with CL40 latency and 2Rx4 organisation. ECC and registered buffering make it suitable for workstation and server platforms that require error correction and signal integrity.

Replaces Hynix DDR5 4800 RDIMMs

The module is a direct replacement for Hynix part numbers HMCG94AEBRA, HMCG94MEBQA109N, HMCG94MEBQA112N, HMCG94MEBQA121N and HMCG94MEBQA123N. The upgrade is worth it when a system needs JEDEC-standard registered ECC memory and the existing slots support DDR5 4800 RDIMMs.

For servers and workstations needing registered ECC

This memory suits administrators upgrading or repairing DDR5 4800 registered ECC platforms. It is not for standard desktop computers, which cannot use registered DIMMs. Buyers who need unbuffered or load-reduced ECC modules should look at a different product type.

商品問答

Will this 288-pin DDR5 4800 CL40 RDIMM fit my server's DIMM slots?

The module uses the standard 288-pin DDR5 form factor and 1.1 V operation; it fits any server or workstation slot that accepts registered ECC RDIMMs at DDR5 4800 speed.

What is the correct installation step for this registered ECC DDR5 module?

Power down the system, open the chassis, align the module notch with the slot key, press firmly until both retention clips click, then verify in BIOS that ECC registered mode is active.

How do I know when this 64 GB 2Rx4 DDR5 module needs replacement?

Run periodic memory diagnostics; replace the module if correctable ECC error counts rise sharply or if the system logs uncorrectable memory errors.
