32 GB DDR4 ECC UDIMM kit for ASRock servers

This 32 GB kit contains two 16 GB DDR4 3200 modules built with ECC unbuffered UDIMM technology. It targets administrators and integrators who need error-correcting memory for ASRock Rack E3C252D4U series motherboards in server or workstation roles.

Check motherboard model and slot population rules

Verify that the target board is an ASRock Rack E3C252D4U, E3C252D4U-2T or E3C252D4ID-2T before ordering. Confirm the CPU installed supports DDR4 3200 unbuffered ECC UDIMMs and that the DIMM slots accept 2Rx8 dual-rank modules at 1.20 V. Consult the board manual for maximum capacity per channel and approved population order.

Fits ASRock Rack E3C252D4U family

The modules plug directly into standard 288-pin DDR4 sockets and operate at the JEDEC 1.20 V level without extra cooling. ECC protection preserves data integrity under sustained load while the unbuffered design keeps latency low for memory-bound workloads. The dual-rank layout leaves remaining slots free for future capacity expansion within the platform limits.
