OWC 128GB DDR4 3200 ECC RDIMM

This single 128GB DDR4 3200 ECC Registered RDIMM is built for Gigabyte G242, G262 and G292 series servers and workstations. It targets administrators who need maximum capacity per slot for virtualization or large datasets.

Installation requires compatible registered ECC

The module installs like any 288-pin DIMM but must go into a platform that supports registered ECC DDR4. It will not work in standard desktop boards and cannot be mixed with unbuffered or load-reduced memory types.

DDR4 3200 caps bandwidth at PC4-25600

The JEDEC-standard interface runs at 1.2V and falls back to 2133, 2400, 2666 or 2933 MT/s if the system clock requires it. Total throughput is limited by the DDR4 bus width and the memory controller in the host server.

Questions about this item

How do I confirm the 128GB DDR4 3200 ECC Registered RDIMM is running at the correct speed and latency after installation?

Check the BIOS or UEFI memory information screen; it should report 3200 MT/s (PC4-25600) with CAS latency 22 and 1.2 V. The module also supports backward-compatible speeds of 2933, 2666, 2400 and 2133 MT/s if the platform requires them.

What comes in the box with the OWC 3R2D48R4128G 128GB module and is any extra hardware needed?

The package contains a single 128GB 288-pin DDR4 ECC Registered RDIMM. No additional cables, brackets or cooling accessories are required for installation in a compatible Gigabyte server chassis.

Which capacity or rank option should I choose for a Gigabyte G292-2G0 server that needs maximum memory per slot?

This 128GB 8Rx4 module is the highest-capacity single DIMM listed for the G292-2G0, G292-280, G262-ZO0, G242-Z11 and G242-Z12 platforms, delivering the maximum density per slot.
