Capacity and configuration

This 64GB kit delivers two 32GB DDR4 3200 UDIMMs rated at CL22 and 1.2V. The modules are unbuffered ECC 2Rx8 parts built with major OEM DRAM and carry a 288-pin layout. They target ASRock X570 Taichi owners who need maximum supported memory with error correction.

Upgrade path

The kit replaces smaller or non-ECC DIMMs to reach 64GB in two slots, leaving two slots free on the four-slot board. The jump is worthwhile when workloads demand ECC integrity and the full capacity ceiling, such as virtualization, ZFS storage or compile farms. Buyers who do not need error correction or who run consumer workloads that cannot use ECC will not benefit.

Build fit

Each stick runs at the standard 1.2V DDR4 voltage and fits any 288-pin DDR4 slot without a heat spreader, so tall CPU coolers are not obstructed. The X570 Taichi memory controller must be configured for 3200 MT/s and ECC operation in the firmware. Systems that require registered or load-reduced DIMMs cannot use this unbuffered kit.

Highlights

  • 64 GB capacity handles heavy workloads
  • DDR4 3200 speed moves data quickly
  • ECC protection detects memory errors
  • 2 V operation reduces power draw
  • 288-pin UDIMM fits ASRock X570 Taichi

Questions about this item

Will the 288-pin DDR4 UDIMM modules fit the four DIMM slots on the ASRock X570 Taichi?

Yes, each 32 GB stick uses the standard 288-pin DDR4 UDIMM form factor that matches the board's four DDR4 slots.

What is the correct seating order for the two 2Rx8 modules on the X570 Taichi?

Install the pair in the A2 and B2 slots first — the slots furthest from the CPU socket — to enable dual-channel operation.

Does the lack of a heat spreader on these 1.2 V modules affect long-term reliability?

No, the modules run at the standard 1.2 V JEDEC voltage and are validated for continuous operation without additional cooling.
