NEMIX RAM 32 GB DDR4 3200 kit for ASUS TRX40

This 32 GB kit contains four 8 GB unbuffered UDIMM modules rated at DDR4 3200 with CL22 latency. It is built for desktop PCs that use 288-pin DDR4 slots and run at 1.2 V. The kit targets owners of the ASUS TRX40 ROG Zenith II Extreme motherboard who need a matched set for a memory upgrade.

Who this suits and who should look elsewhere

The kit suits builders who want a tested, compatible 32 GB upgrade for the named ASUS TRX40 board and who do not require ECC or registered memory. Buyers who need error-correcting code modules, registered DIMMs, or capacities beyond 32 GB should look at a different product.

The specification that decides fit

The decisive specification is the DDR4 3200 CL22 288-pin unbuffered non-ECC UDIMM form factor at 1.2 V. Only systems that accept this exact module type and speed will recognise the kit correctly.

Questions about this item

What motherboard slot and pin count does this 288-pin DDR4 UDIMM kit require?

The kit uses standard 288-pin DDR4 UDIMM slots; four modules occupy four DIMM sockets on the ASUS TRX40 board.

Which orientation notch and seating pressure should I watch when inserting the 1Rx8 modules?

Align the single key notch on each 1Rx8 stick with the slot ridge, then press straight down until both retention clips click — the step often missed is checking both clips engage.

When should I consider replacing the 1.20 V CL22 modules in a heavily loaded workstation?

Plan replacement if ECC errors appear in logs, if the system fails memory diagnostics, or if workload growth demands higher capacity than the current 32 GB kit provides.
