High-Capacity Server Memory Kit

This OWC kit delivers 384GB of DDR4 server memory across six 64GB LRDIMM modules. It targets administrators scaling virtualisation hosts, in-memory databases or high-density compute nodes that require registered ECC reliability. The 288-pin form factor fits compatible enterprise platforms.

Sustained Workload Behaviour

Registered buffering and ECC correction maintain data integrity during continuous multi-threaded operation. The CL21 latency at 2933MHz provides deterministic timing for latency-sensitive services running 24/7. Intel XMP 2.0 profiles allow the platform to configure rated speed automatically without manual tuning.

Pre-Installation Checks

Verify that your motherboard supports LRDIMM topology and a maximum per-slot capacity of 64GB. Confirm the platform accepts 1.20V DDR4 modules and can address the total 384GB across all populated channels. Ensure the BIOS revision enables registered ECC memory operation before installation.

Questions about this item

How much power does the 1.20V 384GB kit draw under sustained load?

Each 64GB LRDIMM runs at 1.20V, the standard DDR4 voltage, so total draw scales with the six modules installed.

Does my motherboard need 288-pin LRDIMM slots and registered ECC support to use this kit?

Yes, the modules are 288-pin DDR4 LRDIMMs with registered ECC; the board must accept that form factor and signalling.

Will the CL21 2933 MHz modules run at their rated speed when paired with slower DDR4 DIMMs already in the system?

The kit is rated for DDR4 2933 at CL21; mixing speeds forces all channels to the lowest common frequency.
