Targeted DDR5 upgrade for ASRock Rack

This 16GB module is built for the ASRock Rack W680D4U-2L2T/G5 motherboard and runs at DDR5 5600 with CL46 latency. It is a non-ECC unbuffered UDIMM suited to workstations and servers that use this platform. The single-rank 1Rx8 design keeps electrical load low on the memory controller.

Standard UDIMM form factor with no heat spreader

The stick uses the 288-pin DDR5 UDIMM layout and operates at 1.10V without a heat spreader. This keeps the module height low for dense chassis or CPU coolers with tight clearance. Major OEM chips from Samsung Micron or Hynix are used depending on supply.

Verify DDR5 slot availability

Confirm the board has a free DDR5 UDIMM slot and that the BIOS recognises 5600MT/s modules at CL46. The system must accept non-ECC unbuffered memory at 1.10V. Buyers who need ECC registered modules or a different voltage should look elsewhere.

Questions about this item

What bandwidth does the DDR5 5600 interface deliver with this module?

The DDR5 5600 (PC5-44800) specification provides up to 44800 MB/s peak transfer rate.

Will the 288-pin UDIMM fit the ASRock Rack W680D4U-2L2T/G5 without a heat spreader?

Yes, the bare 288-pin UDIMM matches the board's DDR5 slots; no spreader means it clears tall CPU coolers.

Which slot should I populate first when installing this single 1Rx8 stick?

Consult the motherboard manual for the primary DDR5 slot — usually the one nearest the CPU — and seat the module until the clips click.
