OWC 32GB DDR4 3200 ECC RDIMM

This 32GB DDR4 3200MHz PC4-25600 ECC Registered RDIMM is built for Supermicro workstations and servers. It operates at 1.2V with CL22 latency and a 2Rx4 rank configuration across 288 pins. The module lacks a heat spreader and is intended strictly for registered ECC platforms. It will not function in standard desktop computers or alongside unbuffered memory.

Replaces Supermicro MEM-DR432L modules

This upgrade matches the exact specifications of Supermicro part numbers MEM-DR432L-CL01-ER32, MEM-DR432L-CL03-ER32 and MEM-DR432L-CL06-ER32. The jump is worth it when extending the life of existing registered ECC infrastructure or building new server capacity with JEDEC-compliant modules. Mixing with unbuffered DIMMs is not supported and will prevent operation.

DDR4 3200 registered ECC limits

The DDR4 3200 standard caps transfer rates at PC4-25600 for registered ECC modules. Registered buffering adds one cycle of latency but enables higher capacities per channel than unbuffered designs. Systems must support ECC and registered signalling; consumer platforms lacking these features cannot use this memory. All DIMMs should match capacity, speed and manufacturer for optimal stability.

Questions sur cet article

Will the 288-pin DDR4 RDIMM fit my Supermicro server DIMM slots?

Yes, the 288-pin DDR4 RDIMM matches the standard server DIMM slot layout used by the listed Supermicro part numbers.

Do I need to populate all channels identically when installing these 2Rx4 registered modules?

For best stability, install matching 32GB 2Rx4 modules in the same channel configuration the motherboard manual specifies; mixing ranks or speeds can prevent boot.

How long will the ECC registered modules last before they need replacement?

The modules carry a limited lifetime warranty and are built to JEDEC and RoHS standards, so they typically remain in service for the life of the server platform.
