Server ECC RDIMM Upgrade

This 16GB DDR3 ECC Registered DIMM is built for Supermicro SuperServer 1017GR and 1017R systems. It delivers 1600MHz speed with CL11 latency at 1.5V. The module uses a 2Rx4 rank configuration on a 240-pin form factor. It will not work in standard desktop computers or alongside unbuffered memory.

Thermals and Power Profile

The module operates at the standard DDR3 voltage of 1.5V without a heat spreader. Registered buffering reduces electrical load on the server memory controller during sustained workloads. ECC circuitry corrects single-bit errors to maintain data integrity under continuous operation. Passive cooling relies on system airflow within the 1U or 2U chassis.

Compatibility and Replacement Scope

This part replaces Supermicro MEMDR316LHL01ER16, MEMDR316LSL01ER16, MEMDR316LSL03ER16 and MEMDR316LSV01ER16 modules. The single 16GB stick allows precise capacity scaling in matched-channel architectures. OWC validation testing covers JEDEC and RoHS compliance for warranty-safe deployment. Buyers needing unbuffered DIMMs or desktop DDR3 cannot use this module.

Questions about this item

How is the 240-pin DDR3 RDIMM installed in a SuperServer 1017GR, and what step is often missed?

Power down the server, open the chassis, align the notch on the 240-pin module with the slot key, press firmly until both latches click, then verify in BIOS that the 16GB module registers at 1600MHz with ECC active.

What replacement might be needed later for this ECC registered module?

If a correctable error count rises, swap the single 16GB DIMM for another 2Rx4 PC3-12800 CL11 1.5V registered module; unbuffered memory cannot be mixed with this registered kit.

What limit appears first under sustained load on this 16GB DDR3 1600 RDIMM?

The 16GB capacity ceiling is reached before bandwidth; once the working set exceeds 16GB the system swaps to disk, so add a second identical 16GB DIMM to raise the limit to 32GB.
