Server-grade memory upgrade
This OWC module delivers 128GB of DDR4 ECC registered memory for Supermicro H11SSL-NC and related server boards. It targets administrators extending the service life of existing infrastructure or building new workstation and NAS systems with a single high-density DIMM.
Registered ECC with 8Rx4 organisation
The stick runs at 3200MHz CL22 (PC4-25600) on 1.2V and uses an 8Rx4 layout across 288 pins. JEDEC compliance and backward compatibility with 2133, 2400, 2666 and 2933MHz buses ensure it will negotiate the highest common speed the platform supports.
Single-slot density for dense configs
Occupying one DIMM slot frees remaining channels for additional capacity without mixing registered and unbuffered or load-reduced modules. The lack of a heat spreader keeps the profile low for tight server chassis, while ECC registration handles error correction for mission-critical workloads.

Questions about this item
What does the 3200 CL22 rating mean for actual throughput in a server?
The module runs at DDR4 3200 (PC4-25600) with CL22 latency, providing the JEDEC-standard data rate when the platform operates at that speed.
How does the DDR4 3200 (PC4-25600) interface limit performance in practice?
The DDR4 3200 interface caps the peak transfer rate to the PC4-25600 specification; the module will down-clock to 2133, 2400, 2666 or 2933 MT/s if the motherboard requires it.
What physical slot and clearance does this 288-pin RDIMM need?
It fits a standard 288-pin DDR4 RDIMM socket and has no heat spreader, so it clears typical server DIMM spacing.
