16GB DDR3L ECC RDIMM for Supermicro servers

This registered ECC module is built for Supermicro SuperServer 6047R, 7047R, 8017R, 8027R and 8028B systems. It will not work in standard desktop computers and cannot be mixed with unbuffered memory. The single 16GB stick adds capacity to compatible workstation, server, NAS or router platforms.

240-pin DDR3L form factor at 1.35V

The module uses the 240-pin DDR3L interface and operates at 1.35 volts. No heat spreader is fitted, so it relies on system airflow for cooling. Registered signalling and ECC support are required by the target Supermicro platforms. JEDEC and RoHS compliance ensure a standardised, warranty-safe upgrade.

DDR3L 1600 CL11 registered operation

Rated at DDR3L 1600 (PC3L-12800) with CAS latency 11, the module runs at stock speed and voltage in supported SuperServer chassis. Registered buffering reduces electrical load on the memory controller. ECC corrects single-bit errors to maintain data integrity in continuous server workloads.

Questions about this item

What speed does the DDR3L 1600 PC3L-12800 interface actually deliver in a Supermicro SuperServer?

The module runs at DDR3L 1600 (PC3L-12800) with CL11 latency, so the memory bus operates at 1600 MT/s in the listed SuperServer 6047R, 7047R, 8017R, 8027R and 8028B models.

Will this 240-pin 1.35 V ECC registered DIMM fit the memory slots in a Supermicro SuperServer 8027R?

Yes — it is a 240-pin DDR3L RDIMM at 1.35 V, matching the slot and voltage requirements of the SuperServer 8027R series.

What is the correct installation sequence for a single 16 GB 2Rx4 registered module in these Supermicro servers?

Populate the lowest-numbered DIMM slot for the CPU first; the common mistake is skipping that slot and inserting the module in a higher bank, which prevents the system from posting.
