System-specific DDR5 ECC kit

This NEMIX RAM kit supplies 64 GB of DDR5 ECC unbuffered memory in two 32 GB modules. It is built for the ASRock Rack W680D4ID-2T/G5/X550 motherboard and runs at 5600 MT/s with CL46 latency at 1.1 V.

Replacing non-ECC or slower DDR5

The kit upgrades systems that currently run non-ECC memory or lower-speed DDR5, adding error correction and the full 5600 MT/s data rate. The jump is worth it when workloads demand data integrity and the board’s qualified memory list includes this part number.

Build fit for W680D4ID platforms

The 288-pin UDIMMs install directly into the board’s DDR5 slots without a heat spreader, leaving clearance for tall CPU coolers. Each module uses a 2Rx8 organisation, so the memory controller sees two ranks per DIMM for maximum density per channel.

Questions about this item

Will the 288-pin DDR5 UDIMM modules fit the ASRock Rack W680D4ID-2T/G5/X550 motherboard slots?

Yes, the kit uses the standard 288-pin DDR5 UDIMM form factor that matches the motherboard's memory slots exactly.

What is the correct seating technique for these unbuffered ECC modules, and what step do builders often miss?

Align the notch with the slot key, press straight down until both retention clips click audibly, then verify both clips are fully latched — partial seating is the most common error.

When should the 2Rx8 ECC UDIMM kit be replaced in a server workload?

Replace modules if ECC correctable-error counters rise steadily, if the system logs uncorrectable memory errors, or if diagnostic tests report persistent faults on either 32GB module.
