ASUS TRX40 Zenith II Extreme DDR4 Upgrade

This 16 GB DDR4 3200 module is built for the ASUS TRX40 ROG Zenith II Extreme motherboard. It targets enthusiasts and workstation users who need a single 1Rx8 UDIMM to expand system memory without ECC or registered buffering.

Single 288-Pin UDIMM in the Box

The package contains one 16 GB stick rated at PC4-25600 CL22 1.20 V. No heat spreader, extra cables, software or additional modules are included, so the upgrade adds exactly one rank of unbuffered memory to a compatible slot.

Standard UDIMM Installation

The 288-pin DIMM installs like any desktop DDR4 module: align the notch, press until the latches click, then power on. Because the board is qualified for this part number, the main risk is seating the stick fully; an incomplete insertion will prevent the system from posting.

Questions about this item

Will the CL22 latency ever need adjustment as the module ages?

CAS latency is a fixed timing set by the SPD; it does not drift or require retuning during the module's service life.

What limits continuous throughput at DDR4 3200 speed?

The 1Rx8 organisation and CL22 timings cap sustained bandwidth before thermal or voltage limits appear.

How much heat does the 1.20 V UDIMM produce under all-day load?

At 1.20 V without a heat spreader the module runs cool; typical case airflow is sufficient for continuous operation.
