Color Green/Black

  • 128 GB total capacity from four 32 GB modules
  • DDR5 5600 speed rated at PC5-44800 bandwidth
  • CL46 latency at standard 1.1 V operation
  • Unbuffered non-ECC design fits consumer desktop boards
  • 288-pin DIMM form factor for DDR5 motherboard slots

Capacity and kit layout

This A-Tech kit provides 128GB of DDR5 desktop memory across four 32GB modules. The unbuffered non-ECC DIMMs are built for standard consumer platforms that accept quad-channel population.

Compatibility checklist

Verify that your motherboard and processor support DDR5 at 5600 MT/s and 288-pin DIMM slots before ordering. The modules run at 1.1V with CL46 timing and require a platform qualified for PC5-44800 operation.

Build integration

Populating all four slots delivers the full 128GB capacity while leaving no free DIMM sockets for later expansion. The green and black modules have no heat spreader, so they fit under most CPU coolers without clearance conflicts.

Questions about this item

Will this 128 GB kit fit a motherboard with four DDR5 DIMM slots?

Yes, the kit contains four 32 GB modules that each use the standard 288-pin DDR5 DIMM form factor, so they occupy all four slots on a typical desktop board.

Does the memory run at 1.1 V without enabling XMP or EXPO?

The modules are rated for 1.10 V at the standard DDR5 5600 speed, so they will operate at that voltage by default on any compatible platform.

Can I use this quad-channel kit on a dual-channel consumer CPU?

The four modules will work on a dual-channel CPU; the memory controller will simply run them in dual-channel mode across the four populated slots.
