Capacity and configuration

This kit delivers 128GB of DDR4 memory across four 32GB UDIMM modules. It targets workstations and high-end desktops that require large memory capacity for demanding workloads.

Build integration

The modules run at DDR4 3200 with CL22 latency and 1.20V voltage, using 2Rx8 organisation on 288-pin slots. Unbuffered non-ECC design fits standard desktop motherboards with four available DIMM slots.

Upgrade context

Replaces smaller-capacity DDR4 kits when 128GB is needed for memory-intensive applications. The jump is worth it when current capacity limits multitasking, virtualisation or content-creation workloads.

Questions about this item

Does the CL22 latency limit throughput during long workloads?

CL22 is the rated CAS latency; sustained throughput depends on the motherboard memory controller and cooling.

How much heat do four 32 GB modules produce at 1.2 V all day?

Each module runs at 1.20 V without a heat spreader; total power scales with load and case airflow.

Must the MSI Creator TRX40 motherboard have four free 288-pin slots?

Yes, the kit contains four 288-pin UDIMMs and requires four available DDR4 slots on the board.
