256GB DDR4 3200 kit for AMD TRX40 workstations

This kit supplies 256GB of DDR4 3200 memory across eight 32GB unbuffered UDIMM modules. It is built for AMD TRX40 chipset motherboards and suits professionals who need high capacity for rendering, virtualization or large datasets.

DDR4 3200 bandwidth and CL22 latency ceiling

The DDR4 3200 (PC4-25600) interface caps peak throughput at the standard data rate, and the CL22 timing sets the minimum latency each request incurs. Eight dual-rank 2Rx8 modules populate every slot on typical TRX40 boards, so no further expansion is possible without replacing the kit.

Verify eight-slot support and 3200MHz qualification

Confirm your motherboard provides eight DDR4 UDIMM slots and lists 3200MHz operation with 32GB dual-rank modules in its qualified vendor list. The kit runs at 1.20V without XMP profiles, so the board must boot at JEDEC defaults. Systems limited to four slots or lower densities cannot use this configuration.

Questions about this item

Which capacity kit should I pick if I need the full 256 GB for an AMD TRX40 workstation?

The 256 GB kit ships as eight 32 GB modules, giving you the maximum supported density in a single matched set.

What does the 3200 MHz rating mean once the modules are installed in a TRX40 board?

The kit runs at DDR4 3200 (PC4-25600) with CL22 timings at 1.2 V, delivering the rated throughput without manual tuning.

How does the 288-pin UDIMM interface limit speed or capacity on this platform?

The unbuffered 288-pin DDR4 UDIMM form factor caps each DIMM at 32 GB and 3200 MHz, which this eight-module kit fully utilises.
