Server ECC RDIMM for Workstations
This 32GB OWC DDR4 module runs at 2400MHz with CL17 latency and 1.2V power draw. It uses a 288-pin registered ECC design built to JEDEC standards for server, workstation and NAS systems. The 2Rx4 rank configuration provides error correction and signal buffering required by multi-socket platforms. It is not compatible with standard desktop motherboards or unbuffered memory.
Direct Replacement for Supermicro Parts
This module matches the specifications of Supermicro part numbers MEM-DR432L-HL01-ER24, MEM-DR432L-HL02-ER24 and MEM-DR432LC-ER24. The upgrade is worth it when existing slots are populated with lower-capacity registered DIMMs or when ECC integrity is required for data-critical workloads. It cannot be mixed with unbuffered memory and will not function in consumer desktop boards.
32GB Capacity for Multi-Socket Scaling
A single 32GB stick lets administrators populate dense memory channels in servers that support registered DDR4. It handles virtualisation hosts, database buffers and large file caches where error correction prevents silent data corruption. Headroom runs out when the platform's maximum registered DIMM count or total memory limit is reached, requiring higher-density modules or additional CPU sockets.

Questions about this item
Does this 288-pin DDR4 RDIMM fit a standard server DIMM slot?
Yes, the module uses the 288-pin DDR4 RDIMM form factor that matches standard server and workstation memory slots.
What is the correct seating procedure for this registered ECC module?
Align the notch with the slot key, press straight down until both side latches click, and verify the module height sits flush — registered DIMMs need firm, even pressure.
Will the 1.2 V, CL17 2Rx4 configuration require any future firmware or voltage adjustment?
No, the module runs at the JEDEC-standard 1.2 V and CL17 timings; no firmware updates or voltage changes are needed during its service life.
