System-specific ECC UDIMM for ASRock servers

This 32 GB DDR4 module runs at 3200 MT/s with CL22 latency and 1.20 V operation. It is built as a 2Rx8 unbuffered ECC UDIMM on a 288-pin PCB and validated for ASRock Rack motherboards including the E3C252D4U series.

Sustained-load stability with ECC protection

Every module undergoes rigorous stress testing under load to verify reliability in continuous server and workstation workloads. The on-die error-correcting code detects and corrects single-bit errors in real time, preventing data corruption during long-running compute or storage tasks.

32 GB single-module capacity

The kit provides 32 GB in a single UDIMM, so total system memory scales in 32 GB increments per populated slot. Buyers who need smaller per-slot increments or non-ECC memory for consumer platforms cannot use this part.

Questions about this item

Does the 1.2 V CL22 DDR4 3200 module generate noticeable heat when running continuously?

The module operates at 1.2 V with no heat spreader, so it runs cool under sustained loads; typical case airflow is sufficient.

What must my ASRock Rack board already provide for this 288-pin ECC UDIMM to function?

The motherboard must support DDR4 3200 ECC unbuffered memory and have a free 288-pin UDIMM slot; the ME25600-328K1 is validated for E3C252D4U series boards.

Will this 2Rx8 32 GB stick work alongside my existing 1Rx8 DDR4 3200 modules?

Mixed-rank configurations are supported on compatible ASRock Rack platforms; the system will run all modules at the lowest common speed and latency.
