OWC 32GB DDR4 3200MHz ECC RDIMM

This 32GB DDR4 3200MHz CL22 1.2V 288-pin ECC Registered RDIMM is built for Supermicro motherboards H11DSi, H11DSi-NT, H11DST-B, H11DSU-iN and H11SSL-C. It delivers 32GB of registered, error-correcting memory per module for server and workstation platforms.

Suited for ECC registered slots only

This module suits technicians upgrading or repairing the listed Supermicro boards with validated ECC registered memory. It will not work in standard desktop computers and cannot be mixed with unbuffered memory, so builders needing non-ECC or consumer DIMMs should look elsewhere.

2Rx4 registered ECC at CL22

The memory is organised as 2Rx4 registered ECC with a CAS latency of CL22 at DDR4 3200 (PC4-25600). This specification determines compatibility with the target Supermicro platforms and prevents use in systems that require unbuffered or different rank configurations.

Perguntas sobre este artigo

How much power does the 1.2V DDR4 module draw when the server runs continuously?

Each 32GB RDIMM operates at 1.2V, the standard DDR4 voltage, so power draw stays at the JEDEC baseline for registered ECC modules under sustained load.

Which motherboard must I already have for this registered ECC memory to function?

The module is validated for Supermicro H11DSi, H11DSi-NT, H11DST-B, H11DSU-iN and H11SSL-C boards that support DDR4 registered ECC RDIMMs.

Can I add this 2Rx4 CL22 stick beside older Supermicro MEMDR432LCL01ER32 modules?

Yes, it replaces Supermicro part numbers including MEMDR432LCL01ER32, but OWC advises matching capacity, speed and vendor for best stability.
