ASRock TRX40 Taichi DDR4 kit

This 64 GB kit contains two 32 GB DDR4 UDIMMs built for the ASRock TRX40 Taichi motherboard. It targets workstation builders and power users who need high capacity for rendering, virtualization or large datasets. The modules run at 3200 MT/s with CL22 latency at 1.20 V. No heat spreader is fitted, keeping the profile low for tight cooler clearance.

Two-slot unbuffered upgrade

Each stick is a 288-pin 2Rx8 non-ECC unbuffered DIMM, so the board must provide two free DDR4 slots and a CPU that supports unbuffered memory at this speed. The kit frees the remaining slots for future expansion if the platform allows more than two modules. No extra voltage or BIOS tuning is required beyond the rated 1.20 V JEDEC setting.

Samsung Micron Hynix ICs tested

Major OEM Samsung, Micron or Hynix ICs are used and stress-tested under load before shipping. The package includes only the two memory modules; no software, drivers or additional accessories are bundled. Lifetime replacement warranty and US-based IT support are provided by the manufacturer.

Questions about this item

Does the CL22 latency limit throughput during long rendering jobs?

CL22 is the rated CAS latency at DDR4 3200; sustained throughput depends on the memory controller and workload, not on the latency figure alone.

How much heat do the modules produce when running continuously at 1.2 V?

These unbuffered UDIMMs operate at 1.2 V without a heat spreader; they generate modest heat typical of standard DDR4 3200 modules under load.

Must the ASRock TRX40 Taichi motherboard already be installed for this kit to work?

Yes, the 288-pin DDR4 UDIMM kit is validated for the ASRock TRX40 Taichi; the board must be present and support 2Rx8 32 GB modules.
