  • 240-pin RDIMM form factor fits select registered-memory platforms only

ECC Registered Server Memory Kit

This OWC kit provides 16GB of DDR3L ECC Registered memory in a matched pair of 8GB modules. It is built for workstations, servers, NAS systems and routers that require registered DIMMs with error correction. The modules run at 1866MHz with a CAS latency of 13 at 1.35V.

For Registered DIMM Platforms Only

Suitable for administrators upgrading or repairing systems that specifically demand DDR3L 240-pin RDIMMs with a 1Rx4 organisation. It is not for standard desktop computers or any platform that only accepts unbuffered memory. It also cannot be mixed with unbuffered modules in the same system.

240-Pin DDR3L RDIMM Form Factor

The decisive specification is the 240-pin DDR3L Registered DIMM form factor combined with ECC functionality. Only systems designed for this exact module type will accept the kit; all other platforms are physically or electrically incompatible.

Questions about this item

Should I choose the 16GB dual-channel kit or buy single modules?

The 16GB kit contains two matched 8GB modules tested together for dual-channel operation, avoiding timing mismatches that can occur with separate purchases.

What does the PC3L-14900 rating mean for my server?

PC3L-14900 indicates a peak transfer rate of 14900 MB/s at 1866 MHz, delivering the rated bandwidth when the platform runs the memory at its specified speed.

Is the 240-pin DDR3L interface compatible with standard DDR3 slots?

The 240-pin DDR3L modules fit DDR3 sockets and run at 1.35 V; they will operate at 1.5 V if the system does not support the lower voltage, but ECC registered function requires a compatible workstation or server platform.
