Designed for MSI Creator TRX40

This 64 GB kit contains two 32 GB DDR4 3200 UDIMM modules built to match the MSI Creator TRX40 motherboard. It targets professionals and enthusiasts who need a simple capacity upgrade for compatible workstations. The non-ECC unbuffered design suits desktop platforms that do not require error-correcting memory. Buyers who need registered or ECC modules for server platforms cannot use this kit.

Standard voltage and latency

The modules operate at 1.2 V with a CAS latency of 22 at 3200 MT/s. Power draw and thermal output follow the normal profile for DDR4 UDIMMs at this voltage and speed. No heat spreaders are fitted, so airflow across the sticks determines operating temperature. Systems without adequate case ventilation may see higher module temperatures under sustained load.

Ready to install with no extras

The package supplies only the two memory modules; no software, cables or additional hardware are included. Installation is a standard DIMM insertion that most users complete in minutes by following the motherboard manual. Lifetime replacement coverage is handled by the manufacturer, not the shop. Users who expect bundled utilities or RGB control software will not find them here.

Questions about this item

How do I install the 288-pin DDR4 UDIMM modules on the MSI Creator TRX40 and what step is often missed?

Align the notch on each 288-pin module with the slot key, press down firmly until both retention clips click, then verify in BIOS that both 32 GB sticks are detected at 3200 MT/s.

What maintenance or replacement will this 64 GB kit need over time?

No routine maintenance is required; the modules carry a lifetime replacement warranty, so a failed stick is exchanged rather than serviced.

What limit appears first when the 2Rx8 CL22 memory runs sustained workloads?

The CL22 latency at 1.20 V is the primary constraint; bandwidth caps at the rated 3200 MT/s PC4-25600 ceiling under continuous load.
