System-Specific DDR4 ECC UDIMM

This 16 GB DDR4 3200 module is built for ASRock Rack motherboards including the E3C256D4ID2, E3C256D4ID-2T, E3C256D4U-2L2T and E3C256D4U-2L2T/BCM. It delivers ECC error correction and unbuffered operation for servers and workstations that require data integrity. The single 288-pin DIMM installs directly into compatible platforms.

DDR4 3200 speed and CL22 latency

The PC4-25600 rating sets the maximum transfer rate, while the CL22 timing defines the minimum cycle delay. Systems that cannot run at 3200 MT/s will downclock the module to the highest supported DDR4 speed. ECC functionality operates only on platforms with a compatible memory controller.

2Rx8 dual-rank organisation

The 2Rx8 configuration places sixteen memory chips across two ranks, increasing density per slot compared to single-rank alternatives. Boards limited to single-rank DIMMs or a maximum rank count per channel will not accept this module. Verify the motherboard qualification list before purchase.

Questions about this item

Should I pick the 16 GB module or add multiple sticks for my ASRock board?

This listing is a single 16 GB stick; add more identical modules to reach the capacity your motherboard supports.

What does the 3200 MHz rating deliver once installed in a compatible server?

The module runs at DDR4 3200 (PC4 25600) with CL22 latency at 1.2 V, giving the rated throughput when the board enables that speed.

How does the 288-pin ECC UDIMM interface limit performance in practice?

As an unbuffered ECC UDIMM it plugs directly into standard DDR4 slots, so the memory controller and board topology set the real-world ceiling.
