Kit composition and target system

This kit delivers sixty-four gigabytes of DDR5 memory in four sixteen-gigabyte modules. It is built for the ASRock Rack W680D4ID-2T/G5/X550 motherboard and suits workstations or servers that require that exact capacity and speed combination.

What the kit includes

The package contains four unbuffered UDIMM modules rated at DDR5 5600 with CL46 timings and 1.1 volt operation. No heat spreaders are fitted, so the modules rely on case airflow for cooling.

Deciding specification

The memory is non-ECC and single-rank 1Rx8, so it will not meet requirements for error-correcting code or registered memory configurations. Buyers who need ECC or registered DIMMs must choose a different kit.

Questions about this item

Will the 288-pin DDR5 modules need any thermal maintenance over time?

These modules have no heat spreader, so dust buildup on the bare PCB can reduce cooling; occasional compressed-air cleaning keeps temperatures stable.

What limits sustained throughput at DDR5 5600 CL46?

The CL46 latency and 5600 MT/s data rate set the bandwidth ceiling; the memory controller on the W680D4ID-2T/G5/X550 cannot push beyond JEDEC spec.

How much power and heat does the 64 GB kit produce at 1.1 V all day?

At 1.1 V the four 1Rx8 modules draw minimal power and run cool without a spreader, so case airflow alone handles the thermal load.
