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.

Questions about this item

How much power does the 1.2V LRDIMM draw under continuous server load?

The module operates at 1.2 volts, the standard JEDEC voltage for DDR4 LRDIMMs, so power draw scales with capacity and rank count rather than exceeding the spec.

Which motherboard slots and CPU memory controllers support this 288-pin 4Rx4 ECC LRDIMM?

It is validated for Supermicro H12SSL-CT, H12SSL-NT, H12SSW-iNR and H12SSW-NTR boards that accept DDR4 288-pin LRDIMMs; the CPU must support load-reduced ECC memory.

Can I mix this 3200 CL22 4Rx4 module with existing 2666 or 2933 MHz registered ECC DIMMs?

No — load-reduced ECC cannot be mixed with registered or unbuffered ECC, and the system will run all modules at the lowest common speed if types matched.
