Capacity and Compatibility

This NEMIX RAM kit provides 64GB of DDR4 memory across four 16GB modules. It is built for ASRock Rack motherboards including the E3C252D4U, E3C252D4U-2T and E3C252D4ID-2T, delivering ECC error correction in an unbuffered UDIMM form factor.

Upgrade Path

The kit replaces lower-capacity or non-ECC DDR4 UDIMMs in compatible ASRock Rack systems. The jump is worth it when workloads demand 64GB of registered-grade reliability without registered-module overhead, or when populating all four slots with matched 2Rx8 modules at 3200 speed.

Build Integration

Each module runs at 1.2V with CL22 timing and uses a 288-pin DDR4 interface, requiring a motherboard that supports unbuffered ECC UDIMMs at PC4-25600. The absence of heat spreaders keeps the profile low for dense server chassis, while the four-module kit fills a full quad-channel set for maximum bandwidth.

Questions about this item

Will the 288-pin DDR4 UDIMMs fit the ASRock E3C252D4U motherboard DIMM slots?

Yes, the kit provides four 288-pin DDR4 ECC UDIMMs that match the ASRock E3C252D4U, E3C252D4U-2T and E3C252D4ID-2T motherboard slots exactly.

What is the correct way to install the four 16 GB modules so the board runs in quad-channel mode?

Populate all four DIMM slots with the 2Rx8 modules; the common mistake is leaving a slot empty or mixing ranks, which drops the board to dual-channel operation.

When should the ECC UDIMMs be replaced if they start logging corrected errors?

Replace a module once the system logs show a rising corrected-error count on that DIMM, as ECC can only correct single-bit errors before data integrity is at risk.
