64GB ECC LRDIMM server memory

This OWC module provides 64GB of DDR4 2933 ECC Load-Reduced memory for servers and workstations. It uses a 288-pin LRDIMM form factor with CL21 latency and 1.2V operation. The quad-rank 4Rx4 design helps maximise capacity in supported platforms.

Suits Fujitsu-compatible servers, not desktops

This memory fits systems that accept DDR4 ECC LRDIMMs such as the listed Fujitsu part numbers. It will not work in standard desktop computers or motherboards that require unbuffered or registered ECC DIMMs. Builders needing consumer memory should choose a different type.

Quad-rank 4Rx4 LRDIMM requirement

The module uses a 4Rx4 Load-Reduced organisation that the memory controller must support. Mixing with unbuffered or registered ECC DIMMs is not possible. Verify that your platform accepts 4Rx4 LRDIMMs before purchase.

商品問答

Will the OWC 64GB DDR4 2933 CL21 4Rx4 ECC LRDIMM work in a standard desktop motherboard?

No, this ECC load-reduced DIMM is designed for servers and workstations only and will not function in standard desktop computers.

Can I mix this 64GB LRDIMM with existing ECC registered DIMMs in my server?

No, the manufacturer highlights state it cannot be mixed with unbuffered or ECC registered memory; all slots must use load-reduced modules.

How can I verify the module is running at the correct 2933MHz speed after installation?

Check the system BIOS or use a hardware monitoring tool to confirm the memory operates at PC4-23400 2933MHz CL21.
