128GB DDR4 ECC Kit

This OWC kit provides 128GB of DDR4 memory across eight 16GB unbuffered UDIMM modules. It targets workstations, servers and NAS systems that require error-correcting code for data integrity. The modules run at 2666MHz with CL19 latency and operate at 1.2V.

Installation Notes

The 288-pin DIMMs fit standard desktop slots and are backward compatible with 2133MHz and 2400MHz platforms. No heat spreaders are present, so clearance is minimal. The main risk is populating all eight slots on a consumer board that only supports four or six modules per channel.

Sustained Load Behaviour

Under continuous workloads the JEDEC-compliant modules maintain their rated 2666MHz speed without thermal throttling because they lack spreaders and run at the standard 1.2V. ECC operation corrects single-bit errors in real time, preventing silent data corruption during long compute or storage tasks.

Perguntas sobre este artigo

Will this kit work in a motherboard that only supports 2133MHz or 2400MHz DDR4?

Yes, the modules are backward compatible with 2133MHz and 2400MHz speeds and will run at the highest speed the motherboard allows.

Does this ECC unbuffered memory require a workstation or server CPU to function?

ECC unbuffered DIMMs need a platform that supports ECC; many consumer desktop chipsets do not enable it, so verify your CPU and motherboard specifications first.

How many DIMM slots are needed to install the full 128GB kit?

The kit contains eight 16GB modules, so eight free 288-pin DDR4 slots are required to populate the entire set.
