32GB DDR4 ECC RDIMM for Supermicro servers

This 32GB DDR4 3200 CL22 registered DIMM is built for Supermicro H11SSL and H12DSG series motherboards. It targets administrators who need ECC registered memory to maintain data integrity in multi-socket server workloads. The module runs at 1.2 V and fits the standard 288-pin DDR4 slot. It is not compatible with desktop boards that only accept unbuffered memory.

Registered ECC is the deciding specification

The module is a 2Rx4 registered ECC RDIMM. That combination is mandatory for the listed Supermicro platforms and will not work in systems that require unbuffered non-ECC DIMMs. Mixing this stick with unbuffered memory is not supported. Verify that your motherboard specifically calls for registered ECC DDR4 before purchase.

Standard voltage and no heat spreader

Operating at the JEDEC standard 1.2 V keeps power draw low for dense server configurations. The absence of a heat spreader means airflow across the PCB is the only cooling path; ensure the chassis provides sufficient front-to-back airflow over the memory slots. Under typical server loads the modules run within normal DDR4 thermal limits without additional cooling.

Questions about this item

What does the 3200 MT/s rating mean once the module is installed in a Supermicro H11SSL-i?

The module runs at DDR4 3200 (PC4-25600) with CL22 latency, delivering the rated throughput when the motherboard operates the memory at that speed.

How does the DDR4 ECC Registered interface affect what the system can use?

The 288-pin DDR4 RDIMM is ECC registered and 2Rx4; it works only in servers or workstations that support registered ECC memory and cannot be mixed with unbuffered modules.

What physical slot and clearance does the 32 GB stick need?

It requires a standard 288-pin DDR4 DIMM socket and has no heat spreader, so it fits in the regular memory slots of the listed Supermicro boards.
