Compatible ASRock DDR4 ECC kit

This 128GB kit contains four 32GB unbuffered UDIMMs built for ASRock X570 Taichi motherboards. It targets system builders and IT professionals who need error-correcting memory for workstation or server workloads. The modules operate at standard DDR4 voltage without heat spreaders.

DDR4 3200 CL22 ECC specification

The memory runs at 3200 MT/s with a CAS latency of 22 and a 1.2V operating voltage. Each module is a 2Rx8 288-pin DDR4 ECC UDIMM using major OEM chips from Samsung, Micron or Hynix. ECC support is the single specification that determines suitability for data-integrity workloads.

Four-slot population on X570 Taichi

Populating all four DDR4 slots delivers the full 128GB capacity on the compatible ASRock board. The unbuffered design keeps the memory controller load standard for consumer chipsets. Builders who need registered DIMMs or higher frequencies must choose a different kit.

Questions about this item

What real-world throughput does the DDR4 3200 speed deliver in a live system?

The kit runs at DDR4 3200 (PC4-25600) with CL22 timing at 1.2 V. Actual throughput depends on the memory controller and how many channels the motherboard populates.

What limits does the unbuffered ECC UDIMM interface impose?

Unbuffered ECC modules connect directly to the memory controller, so the platform must support ECC on consumer AM4 sockets; registered or load-reduced DIMMs cannot be mixed with this kit.

What physical clearance do the 288-pin modules need?

Each stick is a standard-height 288-pin UDIMM without a heat spreader, so it fits any DDR4 slot that has normal retention clips and no oversized CPU cooler overhang.
