128GB DDR4-3200 ECC LRDIMM module

This OWC memory module delivers 128GB of DDR4-3200 capacity in a 288-pin ECC load-reduced DIMM. It operates at CL22 latency and 1.2V, using a 4Rx4 organisation. The part is built to JEDEC standards and is validated for the listed Gigabyte server platforms.

Suits Gigabyte R181 and R182 servers only

This module fits Gigabyte R181-Z91, R181-Z92, R182-340, R182-34A and R182-M80 systems that require ECC load-reduced memory. It will not work in standard desktop computers or in boards that accept only unbuffered or registered ECC DIMMs. Buyers who need memory for a consumer motherboard should look elsewhere.

4Rx4 load-reduced organisation decides fit

The single specification that determines compatibility is the 4Rx4 load-reduced architecture. Your system must explicitly support ECC LRDIMM modules with this rank configuration; registered or unbuffered ECC DIMMs cannot be mixed with it. Confirm the platform documentation before purchase.

Questions about this item

How does the 128 GB capacity translate in a live Gigabyte R182-340 system?

The module provides 128 GB of DDR4 ECC Load-Reduced memory, expanding the server's addressable RAM up to the platform's maximum supported limit.

What does the PC4-25600 rating cap at when installed in a Gigabyte R181-Z92?

The module runs at DDR4 3200 CL22; the Gigabyte platform will negotiate the highest common speed, which may be 3200, 2933, 2666, 2400 or 2133 MHz depending on CPU and BIOS.

Will the 288-pin LRDIMM fit the DIMM slots on a Gigabyte R182-M80 motherboard?

Yes, the 288-pin DDR4 ECC Load-Reduced DIMM matches the slot keying and pin count used by the listed Gigabyte server boards.
