128GB DDR4 ECC LRDIMM Module

This OWC module provides 128GB of DDR4 ECC Load Reduced memory in a single 288-pin DIMM. It operates at 3200MHz with a CAS latency of 22 and a voltage of 1.2V. The 4Rx4 configuration is built for high-density server and workstation platforms requiring maximum capacity per slot.

Suited for Gigabyte Servers, Not Desktops

This memory is designed for the Gigabyte R272-Z34, R281-Z91, R281-Z92, R281-Z94 and R282-2O0 systems. It will not work in standard desktop computers or consumer motherboards. Builders needing unbuffered or standard registered ECC DIMMs cannot mix them with this Load Reduced module.

Load Reduced ECC Determines Compatibility

The single specification that decides fit is the Load Reduced ECC design combined with the 4Rx4 organisation. Only platforms qualified for LRDIMM technology can use this module; standard registered or unbuffered slots will reject it.

Questions about this item

Should I choose the 128 GB module or a smaller capacity for my Gigabyte R281-Z92 server?

The 128 GB 4Rx4 LRDIMM delivers maximum density per slot for Gigabyte R281-Z92 servers, reducing the number of modules needed to reach high total memory compared to lower-capacity alternatives.

What does the DDR4 3200 CL22 rating mean once this LRDIMM is installed in a Gigabyte R272-Z34?

The module will run at up to 3200 MT/s with CAS latency 22; if the platform operates at 2133, 2400, 2666 or 2933 MT/s the LRDIMM automatically downclocks to match.

How does the 288-pin DDR4 ECC Load Reduced interface affect compatibility with Gigabyte R282-2O0 systems?

The 288-pin LRDIMM fits only DDR4 LRDIMM slots on Gigabyte R282-2O0 servers and cannot be mixed with unbuffered or registered ECC DIMMs in the same system.
