Compatibility with Gigabyte MC62-G40/41

This 128GB DDR4 3200 ECC RDIMM is built for the Gigabyte MC62-G40 and MC62-G41 server motherboards. It delivers registered, error-correcting memory for workloads that demand data integrity. The single-module design fits one 288-pin slot at 1.2V.

Who should consider other options

Systems that require unbuffered UDIMMs, lower capacities, or non-ECC memory cannot use this module. Builders needing speeds above 3200MT/s or different rank configurations should look elsewhere. Workstations without RDIMM support are not compatible.

Deciding specification: 4Rx4 rank organisation

The quad-rank 4Rx4 layout determines whether the motherboard memory controller can address the full 128GB in a single slot. Verify that your MC62-G40 or MC62-G41 firmware supports this rank structure before purchasing.

Questions about this item

My Gigabyte MC62-G40 motherboard has empty 288-pin DDR4 slots — will this 128 GB registered ECC module work in them?

Yes, this stick is built for the MC62-G40 and MC62-G41 and uses the standard 288-pin DDR4 RDIMM form factor those boards expect.

I plan to leave older DDR4 ECC RDIMMs in the other channels — does the 4Rx4 rank of this module prevent mixing?

The module is a 4Rx4 registered ECC DIMM at 3200 MHz; mixing ranks is supported by the platform but the memory controller will run all channels at the lowest common speed and timing.

After seating the DIMM, how can I confirm the server sees the full 128 GB at 3200 MHz with ECC active?

Check the BIOS memory information page or run a tool such as dmidecode — it should report 128 GB, 3200 MT/s, registered ECC, and CL22 latency.
