OWC 128GB DDR4 ECC LRDIMM for Gigabyte Servers

This 128GB DDR4 3200 ECC Load Reduced DIMM is built for Gigabyte G242-P34, G242-P35, G242-P36, G242-Z10 and G242-Z11 servers and workstations. It operates at PC4-25600 with CL22 latency and a 4Rx4 rank configuration. The module runs at 1.2V and uses a 288-pin form factor without a heat spreader. It is not compatible with standard desktop computers or with unbuffered and registered ECC memory types.

Thermals Noise and Power at 1.2V

The module operates at the standard DDR4 voltage of 1.2V, which helps limit power draw during typical server workloads. Without a heat spreader, thermal performance relies on system airflow across the bare PCB. JEDEC compliance ensures the DIMM meets standard electrical and thermal specifications for sustained operation in qualified platforms. Acoustic output is determined by the server chassis fans rather than the memory itself.

Sustained Load Behaviour and Compatibility

ECC Load Reduced technology reduces electrical load on the memory bus, allowing stable operation at full 128GB capacity during extended compute tasks. The DIMM is backward compatible with 2133MHz, 2400MHz, 2666MHz and 2933MHz bus speeds for flexible deployment. It matches Micron MTA72ASS16G72LZ3G2, Samsung M386AAG40AM3-CWE and Hynix HMABAGL7ABR4N-XNT5 part numbers for direct replacement. Mixing with other memory types is not supported.

Questions about this item

How do I install this 288-pin ECC LRDIMM into a Gigabyte G242-Z10, and what step is often missed?

Power down the server, open the chassis, align the notch on the 288-pin module with the DIMM slot key, press firmly until both retention clips click, then verify in BIOS that the 128GB 4Rx4 module is recognised at 3200MHz with ECC active.

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

No scheduled maintenance is required; keep the server air filters clean so the 1.2V modules stay cool, and replace only if a memory test reports uncorrectable ECC errors or the system fails to post with the module installed.

What limit appears first when this 4Rx4 LRDIMM runs sustained workloads on a G242-P35?

The memory controller will down-clock the module to 2933MHz or 2666MHz if thermal headroom or signal integrity cannot support the full 3200MHz CL22 rate under continuous load.
