System-specific DDR5 ECC kit

This 32 GB kit contains two 16 GB DDR5 5600 modules built for the ASRock Rack W680D4U-2L2T/G5 motherboard. Each stick runs at 1.1 V with CL46 latency and uses 1Rx8 unbuffered ECC chips.

288-pin DDR5 ECC UDIMM form factor

The modules fit only 288-pin DDR5 ECC unbuffered DIMM slots; they will not work in registered, non-ECC or earlier DDR generations. Verify your board accepts PC5-44800 unbuffered ECC before ordering.

Low-voltage operation at 1.1 V

Standard JEDEC voltage keeps power draw modest and thermals manageable without a heat spreader. Passive cooling in a server chassis with adequate airflow is sufficient for continuous operation.

Questions about this item

What does the 5600 speed rating mean once the kit is installed in the ASRock Rack W680D4U-2L2T/G5?

The modules run at 5600 MT/s, delivering PC5-44800 bandwidth when the motherboard sets the memory controller to that data rate.

How does the 288-pin DDR5 interface limit what the kit can do in practice?

The 288-pin DDR5 UDIMM slot provides the electrical and mechanical connection; the board's memory controller determines the maximum stable speed and timing.

Will the two 16 GB sticks fit the ASRock Rack W680D4U-2L2T/G5 without a heat spreader?

Yes, the low-profile 288-pin UDIMM modules have no heat spreader and install directly into the board's DDR5 slots.
