OWC 128GB DDR4 3200 CL22 4Rx4 LRDIMM ECC Memory Upgrade

128GB DDR4 LRDIMM for Supermicro servers

This single 128GB module delivers DDR4 3200 performance with CL22 latency and 1.2V operation. It is built as a 4Rx4 load-reduced ECC DIMM for Supermicro H12SSL-CT, H12SSL-NT, H12SSW-iNR and H12SSW-NTR motherboards. The 288-pin form factor fits server and workstation slots only. Standard desktop systems cannot use this memory.

Sustained workload behaviour with ECC load reduction

The load-reduced architecture lowers electrical load on the memory bus, allowing large-capacity configurations to maintain stability during extended compute tasks. ECC corrects single-bit errors in real time, preventing data corruption in critical applications. Backward compatibility with 2133, 2400, 2666 and 2933MHz platforms lets the module run at the highest speed the host supports. It cannot be mixed with unbuffered or registered ECC DIMMs.

Thermals, noise and power in normal use

Operating at 1.2V keeps power draw low for a 128GB module, reducing heat output inside dense server chassis. No heat spreader is fitted, so airflow across the PCB manages thermals directly. Silent solid-state operation adds no acoustic noise to the system. JEDEC and RoHS compliance confirms the component meets standard voltage and environmental limits for continuous deployment.
