Server-grade 128 GB DDR4 module

This OWC LRDIMM delivers 128 GB of DDR4 3200 memory with ECC load-reduced architecture. It is built for Gigabyte R262, R271 and R272 server and workstation platforms. Standard desktop boards cannot use this module and it must not be mixed with unbuffered or registered ECC DIMMs.

Thermals and power at rated speed

Operating at 1.2 V, the module runs within JEDEC-standard power limits for DDR4 3200. No heat spreader is fitted, so airflow across the DIMM slots handles thermal dissipation in normal server chassis. The load-reduced design reduces electrical loading on the memory bus compared with registered alternatives.

Behaviour under sustained workloads

ECC load-reduced operation maintains data integrity during continuous multi-threaded tasks such as virtualisation, database serving or large-scale compute. Backward compatibility with 2133, 2400, 2666 and 2933 MHz buses allows deployment in older Gigabyte platforms without changing memory speed settings.

Questions about this item

How do I install the 288-pin LRDIMM in a Gigabyte R262-ZA1 and what step is often missed?

Power down the server, open the chassis, align the module notch with the DDR4 slot key, press firmly until both retention clips click, then verify in BIOS that the 128GB 4Rx4 module is recognised at 3200MHz CL22; the step often missed is confirming the system runs in LRDIMM-only mode and does not mix with unbuffered or registered DIMMs.

What maintenance or replacement will this 128GB DDR4 3200 CL22 4Rx4 LRDIMM need over its service life?

No scheduled maintenance is required; keep the server air filters clean so the 1.2V modules stay within thermal limits, run periodic memory diagnostics, and replace only if ECC correctable-error counters rise or a module fails POST.

What limit appears first when this 4Rx4 LRDIMM runs sustained workloads in a Gigabyte R272-P30?

The memory controller’s maximum supported rank count per channel is typically reached before thermal or bandwidth limits, so population rules for 4Rx4 modules restrict how many DIMMs can be installed per CPU.
