Compatible DDR4 ECC UDIMM kit for ASRock Rack

This 128GB kit contains four 32GB DDR4 3200 modules built for ASRock Rack X570D4U, X570D4U-2L2T and X570D4U-2L2T/BCM motherboards. Each stick runs at 1.20V with CL22 timing and uses 2Rx8 unbuffered ECC chips. The 288-pin UDIMM form factor fits the board's standard slots.

Suits servers and workstations needing maximum ECC

Builders filling all four slots on the supported X570D4U variants will reach the platform's 128GB limit with this kit. Systems requiring registered or load-reduced modules cannot use these unbuffered DIMMs. Buyers needing more than 128GB must choose a different motherboard platform.

DDR4 3200 CL22 2Rx8 unbuffered ECC specification

The modules operate at DDR4 3200 (PC4-25600) with a CAS latency of 22 and a 2Rx8 organisation. Unbuffered ECC design provides error correction without the register delay of registered DIMMs. This exact speed, rank and buffering combination is what the X570D4U memory controller expects.

Questions sur cet article

What comes in the box and is anything else needed for installation?

The kit contains four 32 GB DDR4 3200 ECC UDIMM modules. No extra parts are required; install them directly into the motherboard slots.

Should I choose the 4×32 GB kit or a different capacity for the ASRock Rack X570D4U?

This 128 GB kit (4×32 GB) fills all four slots on the X570D4U. Select it when you need the maximum supported capacity; choose a smaller kit only if you plan to leave slots empty.

How does the CL22 3200 MT/s rating affect real-world performance in this server board?

The modules run at 3200 MT/s with 22-cycle CAS latency at 1.2 V, delivering the rated throughput and error correction the X570D4U expects for stable server workloads.
