  • 128 GB total capacity with four 32 GB modules
  • DDR5 4800 speed rated at PC5-38400 bandwidth
  • CL40 latency tuned for DDR5 desktop workloads
  • 1 V operation cuts power versus 1.2 V DDR4
  • Quad-channel kit enables maximum memory throughput

High-capacity DDR5 kit

This 128GB kit contains four 32GB DDR5 modules running at 4800MHz with CL40 latency at 1.10V. It is a non-ECC unbuffered quad-channel kit using 288-pin DIMMs without heat spreaders. The kit targets desktop users who need large memory capacity for heavy multitasking or content workloads.

Straightforward DIMM installation

Modules install like standard DDR5 DIMMs into four slots on a compatible motherboard. No extra cables or software are required. The main risk is buying this kit for a board that only supports DDR4 or a lower maximum capacity, so verify the motherboard memory QVL before ordering.

Suits high-capacity desktop builds

This kit suits workstations and enthusiast desktops that can use 128GB of DDR5 memory across four slots. It is not for laptops, small-form-factor boards with two slots, or systems limited to DDR4. Buyers needing ECC or registered memory should choose a different product.

Questions about this item

Will this kit fit a standard desktop motherboard with four DDR5 DIMM slots?

The kit contains four 288-pin UDIMMs designed for DDR5 desktop boards that support quad-channel population.

My CPU and motherboard list DDR5 4800 at 1.1 V — does this kit match those specs exactly?

Each module is rated 4800 MT/s, CL40, and operates at the standard 1.1 V, matching the platform baseline.

Is any extra cooling or a heat spreader required for sustained workloads?

The modules ship without a heat spreader; they run at the standard 1.1 V, so typical case airflow is usually sufficient.
