Server Memory Kit

This OWC kit provides 32 GB of DDR3L server memory in a matched pair of two 16 GB modules. It is built for workstations, servers, NAS systems and routers that require registered ECC DIMMs.

Registered ECC with 2Rx4 Organisation

Each module is a 240-pin DDR3L 1866 (PC3L-14900) RDIMM running at CL13 latency and 1.35 V. The registered buffer and ECC function are mandatory for the target platforms and cannot be mixed with unbuffered memory.

For ECC Registered Platforms Only

This memory suits administrators upgrading or repairing DDR3L registered ECC systems. It will not work in standard desktop computers or any platform that requires unbuffered non-ECC modules.

Questions about this item

What does the 1866 MT/s rating mean for real-world throughput?

The modules run at 1866 MT/s with CL13 timing, so data moves at the JEDEC DDR3L-1866 rate when the platform enables that speed.

How does the DDR3L PC3L-14900 interface limit performance?

The PC3L-14900 designation sets the maximum JEDEC data rate at 1866 MT/s; the memory cannot exceed that ceiling on any board.

What physical slot and clearance do these 240-pin RDIMMs need?

Each stick is a 240-pin DDR3L RDIMM without a heat spreader, so it fits standard server DIMM sockets and low-profile chassis.
