ASRock TRX40 Taichi 32GB Kit

This 32GB kit contains four 8GB DDR4 UDIMM modules validated for the ASRock TRX40 Taichi motherboard. It targets builders and IT professionals who need a matched, tested set for workstation or server workloads. The modules are unbuffered and non-ECC, suited to standard desktop platforms rather than registered-memory servers.

DDR4 3200 CL22 Capacity

Running at 3200MT/s with CL22 latency and 1.2V, the kit delivers 32GB total across four ranks of 1Rx8 Samsung, Micron or Hynix chips. It handles multi-threaded applications and virtualisation guests comfortably until the four-slot limit is reached; beyond that the platform requires higher-density or registered DIMMs.

No Heat Spreader Included

The package supplies only the four bare UDIMM sticks with no heatsinks, thermal pads or software utilities. Builders with restricted airflow should plan their own cooling, while those needing monitoring tools must rely on motherboard firmware or third-party utilities.

Questions about this item

Will the 3200 MHz CL22 modules run at their rated speed alongside my existing DDR4 memory on the ASRock TRX40 Taichi?

The kit is validated for the ASRock TRX40 Taichi at DDR4 3200 CL22 1.20 V. When mixed with slower DDR4, the motherboard will typically downclock all modules to the lowest common speed and loosest timings.

How can I verify the 4 x 8 GB kit is operating at DDR4 3200 CL22 after installation?

Enter the UEFI on the ASRock TRX40 Taichi and confirm the memory frequency reads 3200 MT/s with CAS latency 22. CPU-Z or HWiNFO in Windows will show the same figures under the SPD and Memory tabs.

Does the MD25600-818K4 package include a heat spreader or any cables, or must I buy them separately?

The modules ship without a heat spreader. The box contains only the four 288-pin UDIMMs; no cables, screws or additional accessories are included.
