SKU CH-MNGZ-37FKQ

A 128 GB DDR5 RDIMM running at 5600 MT/s with a 2Rx4 layout for desktop memory upgrades

  • 128 GB capacity supports larger workloads
  • DDR5 5600 MT/s speed enables faster data rates
  • 2Rx4 organisation improves memory parallelism
  • JEDEC standard ensures broad compatibility
  • Micron DID-agnostic design simplifies procurement

128 GB DDR5 RDIMM for servers

This module delivers 128 GB of DDR5 RDIMM memory in a 2Rx4 configuration rated at 5600 MT/s. It targets data-centre operators and system integrators who need high-density capacity for virtualization, AI training or HPC workloads.

JEDEC-standard build with simplified procurement

Micron uses a DID-agnostic design that trims the number of server MPNs, reducing stock-outs and easing inventory management. The JEDEC-compatible pinout ensures drop-in installation in qualified DDR5 RDIMM slots without proprietary firmware hurdles.

DDR5 RDIMM practical limits

The 5600 MT/s JEDEC speed ceiling applies, so overclocking headroom is not guaranteed. Capacity scales with the number of registered DIMM slots your platform provides; buyers needing more than 128 GB per module or non-registered memory must look elsewhere.

Highlights

  • 128 GB capacity supports larger workloads
  • DDR5 5600 MT/s speed enables faster data rates
  • 2Rx4 organisation improves memory parallelism
  • JEDEC standard ensures broad compatibility

Questions about this item

What DDR5 standard does this 128GB module run at, and what speed does that cap it to?

It follows the JEDEC DDR5 5600 standard, so the module operates at 5600 MT/s.

What physical slot and form factor does this 128GB RDIMM need to fit?

It is a DDR5 RDIMM with a 2Rx4 organisation, so it requires a DDR5 RDIMM slot on a compatible desktop or server board.

How is the module installed, and which alignment step is often missed?

Align the single key notch on the module with the slot ridge, press down firmly until both side clips click, and verify the clips are fully locked.
