NEMIX RAM 96GB (2x48GB) DDR5 5600 CL46 ECC UDIMM memory upgrade for ASRock Rack W680D4U-2L2T/G5

Capacity and configuration

This kit delivers 96GB of DDR5 ECC memory in a matched pair of 48GB modules. It is built for the ASRock Rack W680D4U-2L2T/G5 motherboard and suits workloads that demand high capacity with error correction. The unbuffered design keeps the signal path short for direct CPU attachment. Buyers who need registered DIMMs or lower-density sticks should look elsewhere.

Speed, voltage and latency

Rated at 5600 MT/s with a CL46 timing, the modules run at the standard 1.1V DDR5 voltage. The 2Rx8 organisation provides two ranks per DIMM for density without registered buffering. Headroom exists for large datasets and virtual machines, while the fixed JEDEC profile avoids manual tuning. Systems that require faster JEDEC speeds or lower latencies will not gain them from this kit.

Form factor and platform fit

The 288-pin UDIMM form factor fits the target board’s standard DDR5 slots and needs no heat spreader clearance. ECC support is native to the platform, so no extra configuration is required beyond population rules. The kit frees all remaining slots for future expansion if the board provides more than two channels. Builds using a different chipset, a registered-memory platform or a non-ECC consumer board cannot use these modules.
