OWC 128GB DDR4 3200 ECC Registered RDIMM 8Rx4 288-pin 1.2V CL22 memory upgrade

Server-grade ECC RDIMM for Gigabyte platforms

This OWC module is a 128GB DDR4 3200 ECC Registered DIMM built for Gigabyte G492 and H242 server families. It targets administrators who need high-density registered memory with error correction for workloads that cannot tolerate data corruption. The single-stick design simplifies capacity scaling in qualified chassis.

Registered ECC cannot mix

The 8Rx4 registered architecture requires a memory controller that supports registered operation and will not function in standard desktop boards. Backward compatibility extends to 2133, 2400, 2666 and 2933 MT/s bus speeds, but the module must remain in a registered-only channel population. Mixing registered and unbuffered types on the same platform causes boot failure.

128GB per DIMM decides if density fits your slot

Each stick delivers 128GB at 1.2V with CL22 timing, so total system capacity scales directly with the number of populated slots. Buyers needing less than 128GB per module or systems limited to lower single-DIMM ceilings should select a lower-capacity part.
