128GB DDR3L ECC Registered Kit

This OWC kit supplies 128GB of DDR3L memory across eight 16GB registered DIMMs. It targets servers, workstations and NAS systems that require ECC error correction and registered buffering. Modules run at 1866MHz with CL13 latency and 1.35V operation. The 240-pin form factor fits compatible DDR3L slots.

Verify DDR3L RDIMM support before ordering

Confirm the platform accepts DDR3L registered ECC modules at 1.35V and 240-pin layout. Unbuffered or standard desktop memory will not work in the same slots. Check the system manual for maximum capacity per channel and total slots available. Mixing registered with unbuffered DIMMs is not supported.

Suits legacy server refreshes and ECC workloads

Ideal for administrators extending older DDR3L infrastructure or building cost-sensitive ECC platforms. Not for consumer desktops, laptops or any system that lacks registered memory support. Buyers needing higher speeds, lower voltages or non-ECC operation should look elsewhere.

Questions about this item

What comes in the box and is anything else required for installation?

The kit includes eight 16GB DDR3L 1866 CL13 ECC Registered RDIMM modules totalling 128GB. No extra parts are needed if the server or workstation has eight free 240-pin DDR3L slots and supports registered ECC memory.

How do I choose between the listed capacities or configurations?

This product is a single 128GB kit of eight 16GB 2Rx4 modules. Select it when the target system requires a full 128GB population of registered DDR3L 1866 memory.

What does the 1866MHz rating mean once the memory is installed in a real server?

The modules run at DDR3L 1866 (PC3L-14900) with CL13 latency at 1.35V, delivering the rated throughput provided the platform enables that speed and supports registered ECC DIMMs.
