NEMIX RAM DDR5 64GB kit for Z890I AORUS Ultra

This NEMIX RAM kit supplies 64GB of DDR5 memory in a matched pair of 32GB modules. It is built for the GIGABYTE Z890I AORUS Ultra Mini-ITX motherboard and fits any desktop board that accepts 288-pin DDR5 UDIMMs. The non-ECC, unbuffered design suits standard consumer platforms rather than server or workstation boards that require registered memory.

Standard voltage and latency for everyday operation

Each module runs at 1.10V with a CAS latency of CL46 at the rated 5600 MT/s speed. The 2Rx8 organisation uses major OEM chips from Samsung, Micron or Hynix without a heat spreader, keeping the profile low for tight Mini-ITX layouts. Power draw and thermal output remain at baseline DDR5 levels during typical desktop workloads.

Steady throughput under sustained workloads

The kit maintains its 5600 MT/s data rate and CL46 timing during extended sessions without relying on overclocking headroom. Builders who need error correction, registered buffering or higher frequencies with lower latencies should look elsewhere, as this kit targets standard JEDEC operation for the validated platform.

Questions about this item

How do I install the 288-pin DDR5 UDIMM modules on the GIGABYTE Z890I AORUS Ultra, and what step is often missed?

Align the notch on each 288-pin DDR5 UDIMM with the slot key, press firmly until both retention clips click shut, then enable the 5600 MHz speed in the BIOS — the step most often missed.

What maintenance or replacement will the 2Rx8 DDR5 kit need later?

The modules have no heat spreader and no moving parts, so no scheduled maintenance is required; replacement is only needed if a module fails, which is covered by the lifetime replacement warranty.

What limit appears first under sustained load with the CL46 1.10 V DDR5 5600 memory?

The primary limit is the CL46 latency at the JEDEC-standard 1.10 V; the modules run at the rated 5600 MHz without overclocking headroom, so latency is the first constraint in sustained workloads.
