128GB DDR4 LRDIMM for Gigabyte Servers

This 128GB DDR4 3200 ECC Load Reduced DIMM is built for the Gigabyte G492-Z52, H242-Z10, H242-Z11, H252-3C0 and H252-Z10 platforms. It targets server and workstation operators who need high-density registered memory with error correction. The module will not work in standard desktop computers or alongside unbuffered or registered ECC DIMMs.

Sustained 3200MHz Operation

Running at PC4-25600 with CL22 latency and 1.2V, the module maintains its rated speed under continuous server workloads rather than only in short bursts. The load-reduced architecture reduces electrical load on the memory controller, helping stability when all slots are populated. Backward compatibility with 2133MHz, 2400MHz, 2666MHz and 2933MHz systems allows deployment in mixed-speed environments.

288-Pin LRDIMM Form Factor

The 288-pin LRDIMM fits the DDR4 slots of the listed Gigabyte systems without a heat spreader, simplifying installation in dense chassis. JEDEC and RoHS compliance ensures the module meets industry electrical and environmental standards. ECC load-reduced design supports data integrity for critical applications, while the single-module capacity lets administrators reach high memory totals with fewer occupied slots.

Questions about this item

Does the 1.2V DDR4 3200 LRDIMM run cooler than standard registered ECC modules in a Gigabyte H242-Z10?

Load-reduced modules lower electrical load on the memory bus, which can reduce power draw per DIMM compared to registered ECC at the same speed and voltage.

My Gigabyte G492-Z52 currently has Micron MTA72ASS16G72LZ3G2F1 installed — will this OWC 128GB 4Rx4 module work alongside it?

Yes, the module is validated against Micron MTA72ASS16G72LZ3G2, MTA72ASS16G72LZ3G2F1 and MTA72ASS16G72LZ3G2B3 part numbers for direct compatibility.

Can I mix this 3200 CL22 LRDIMM with existing 2666 MHz ECC load-reduced DIMMs in a Gigabyte H252-Z10?

The module is backward compatible with 2133, 2400, 2666 and 2933 MHz speeds, so it will operate at the lowest common speed when mixed.
