Capacity 128GB

  • Massive 128 GB capacity expands server workload headroom
  • DDR4 3200 MHz speed accelerates data-intensive applications
  • ECC Load Reduced DIMM protects data integrity under heavy load
  • Quad-rank 4Rx4 architecture maximises density per 288-pin slot
  • Standard 1.2 V operation keeps power draw predictable

128 GB DDR4 3200 LRDIMM for servers

This 128 GB A-Tech module runs at DDR4 3200 with ECC and Load Reduced signalling. It uses a 288-pin DIMM form factor, operates at 1.20 V, and carries a CL22 latency rating. The quad-rank 4Rx4 organisation is built for high-density server and workstation platforms.

Suits DDR4 LRDIMM slots needing maximum capacity

It fits systems that explicitly support DDR4 Load Reduced DIMMs with 4Rx4 ranking. Desktop and laptop boards cannot accept this module, and standard registered DIMM slots will not work with the LRDIMM protocol. Buyers who need non-ECC memory or a different rank configuration must choose another part.

The deciding spec is the 4Rx4 Load Reduced

Only motherboards qualified for DDR4 4Rx4 LRDIMM modules can use this stick. Verify the platform’s memory qualification list before ordering; an incompatible slot will not post with this module installed.

Questions about this item

What speed does the PC4-25600 DDR4 3200 interface actually deliver in a compatible server?

The module runs at DDR4 3200 (PC4-25600) with a CAS latency of 22 when installed in a server that supports that speed.

What physical slot and clearance does the 288-pin LRDIMM need?

It requires a 288-pin DDR4 DIMM socket; the module has no heat spreader, so standard server DIMM clearance applies.

How is the 128 GB 4Rx4 LRDIMM installed, and what step is often missed?

Power down the server, open the chassis, align the notch on the 288-pin edge connector, press firmly until both retention clips lock, then consult the system manual for correct channel population order for quad-rank modules.
