Server ECC Registered Upgrade

This OWC 32GB DDR4 3200 CL22 ECC RDIMM is a registered server memory module built for specific Supermicro motherboards. It targets administrators upgrading H12DST-B, H12DSU-iN, H12SSL-C, H12SST-PS or H12SSL-i platforms. The 2Rx4 dual-rank design operates at 1.2V with CL22 latency. It is not compatible with standard desktop computers or unbuffered memory configurations.

Verify Motherboard Slot And Population Rules

Before ordering, confirm your motherboard model matches the listed Supermicro part numbers exactly. Registered ECC DIMMs cannot be mixed with unbuffered modules in the same system. Check the vendor documentation for supported population order, maximum capacity per channel and whether 2Rx4 modules are qualified for your specific BIOS revision. The 288-pin form factor fits DDR4 slots only.

Thermals Noise And Power Draw

The module runs at the standard 1.2V DDR4 voltage without a heat spreader, relying on chassis airflow for cooling. Registered ECC operation adds minimal electrical load compared to unbuffered equivalents. Expect silent passive operation with no moving parts. Power draw scales with the 32GB capacity and 3200MHz speed under typical server workloads.

Questions sur cet article

Does the 32GB DDR4 3200 CL22 ECC RDIMM come as a single module or a kit, and are any extra parts needed?

This is a single 32GB 288-pin DDR4 ECC Registered DIMM. No extra parts are required for installation in a compatible Supermicro motherboard.

Should I choose the 32GB CL22 Registered ECC module or a different capacity for my Supermicro H12SSL-C?

The 32GB 2Rx4 Registered ECC DIMM matches the Supermicro part numbers listed for the H12SSL-C. Select the same capacity and speed for each slot to keep performance consistent.

What does the 3200 MT/s rating mean when the module is running in a Supermicro H12DST-B?

The module operates at DDR4 3200 (PC4-25600) with CL22 latency at 1.2V, delivering the rated throughput and error correction supported by the H12DST-B memory controller.
