OWC 128GB DDR4 ECC RDIMM

This OWC module delivers 128GB of DDR4 3200MHz registered ECC memory in a single 288-pin DIMM. It operates at CL22 latency and 1.2V for Supermicro H11DSi, H11DSi-NT, H11DST-B, H11DSU-iN and H11SSL-C motherboards. The 4Rx4 configuration targets servers and workstations that require maximum capacity per slot.

Verify motherboard and memory type before ordering

Confirm your board is one of the five listed Supermicro models and that it supports registered ECC RDIMMs. This memory will not work in standard desktop computers and cannot be mixed with unbuffered modules. Ensure all installed DIMMs share the same capacity, speed and manufacturer for optimal stability.

Thermals and power in normal use

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 overhead compared with unbuffered memory. Power draw scales with the 128GB density and 3200MHz speed under typical server workloads.

商品問答

Does the 128GB DDR4 3200MHz CL22 ECC RDIMM arrive as a single module or a kit, and are any extra parts required for installation?

The product is a single 128GB 288-pin DDR4 ECC registered DIMM. No additional components are needed; it installs directly into a compatible Supermicro motherboard DIMM slot.

Should I choose this 128GB CL22 module or a lower-capacity alternative for my Supermicro H11DSi system?

Select this 128GB module when the workload demands maximum memory per slot. For lighter workloads or budgets, smaller-capacity DDR4 3200 ECC RDIMMs of the same speed and voltage can be used, but OWC recommends matching capacity, speed and manufacturer across all populated slots.

What does the 3200MHz PC4-25600 rating deliver in a live Supermicro H11SSL-C server?

The module runs at DDR4 3200 with CL22 latency and 1.2V, providing the peak bandwidth and error-correcting stability the H11SSL-C platform expects for virtualization, database or compute tasks.
