  • ECCYes

Capacity 32GB

Struck-through versions exist but are not stocked here.

  • 32GB capacity expands server memory headroom
  • DDR4 3200 speed matches supported system requirements
  • ECC registered design protects data integrity in workloads
  • 2V operation reduces power draw per module
  • Compatible with Gigabyte R181-Z91, R181-Z92, R182-340, R182-34A, R182-M80

Target Systems

This 32GB DDR4 ECC Registered DIMM is built for Gigabyte R181-Z91, R181-Z92, R182-340, R182-34A and R182-M80 servers or workstations. It suits administrators who need error-correcting memory for stable operation in those specific platforms.

Registered ECC Requirement

The module uses a 2Rx4 registered design with ECC, so the system must support registered DIMMs. It will not work in standard desktop boards or in systems that require unbuffered or load-reduced memory.

Build Integration

The single 32GB stick runs at 3200MHz with CL22 latency at 1.2V and fits a 288-pin DDR4 slot. It is backward compatible with 2133, 2400, 2666 and 2933MHz buses, allowing it to slot into existing configurations without voltage changes.

Highlights

Questions about this item

How does the 3200 MHz speed behave once this module is installed in a Gigabyte R182-340 server?

The module runs at DDR4 3200 (PC4-25600) with CAS latency 22; if the platform only supports lower speeds it will automatically clock down to 2933, 2666, 2400 or 2133 MHz.

What does the ECC Registered 288-pin interface mean for compatibility with the listed Gigabyte models?

The 288-pin ECC Registered RDIMM fits the DDR4 slots on the Gigabyte R181-Z91, R181-Z92, R182-340, R182-34A and R182-M80; it cannot be mixed with unbuffered or load-reduced DIMMs.

Will the 32 GB stick physically fit the DIMM sockets on a Gigabyte R181-Z92 without a heat spreader?

Yes — the bare 288-pin PCB is a standard-height RDIMM, so it seats directly in the server’s DDR4 slots without clearance issues.
