ASRock TRX40 Taichi Compatible Kit

This 16 GB kit contains two 8 GB DDR4 UDIMM modules validated for the ASRock TRX40 Taichi motherboard. It targets builders and upgraders who need guaranteed compatibility with that specific platform. The unbuffered, non-ECC design suits standard desktop workloads. Buyers requiring registered ECC memory for server-grade error correction cannot use this kit.

Sustained Load Behaviour

Modules operate at 1.20 V with CL22 timings at the rated 3200 MT/s data rate. The 1Rx8 organisation and major OEM DRAM chips are stress tested under load to maintain stability during extended sessions. Absence of a heat spreader means airflow across the PCB becomes the primary cooling path. Systems with restricted DIMM ventilation may see higher temperatures during prolonged heavy use.

DDR4 Interface Limits

The 288-pin DDR4 interface delivers a peak transfer rate of PC4-25600. Bandwidth and latency are bounded by the DDR4 standard and the motherboard memory controller capabilities. This kit does not support DDR5 platforms or higher DDR4 frequencies beyond the validated 3200 MT/s. Builders needing greater density per module or faster transfer rates must select a different memory specification.

Questions about this item

Does the 1.2 V DDR4 kit run hot or loud under continuous load?

The modules operate at 1.2 V with no heat spreader, so they rely on case airflow; they have no moving parts and produce no noise.

What must my system already have to use this 288-pin UDIMM kit?

A motherboard with DDR4 UDIMM slots that supports 3200 MT/s operation, such as the ASRock TRX40 Taichi, and an available pair of slots for the two 8 GB modules.

Will the CL22 timing work alongside older DDR4 sticks I keep installed?

The kit runs at CL22; mixing with slower or different-latency modules will force the system to run all memory at the lowest common speed and latency.
