Targeted DDR4 UDIMM for ASUS X299

This NEMIX RAM module delivers 32GB of DDR4 3200 memory in a single 288-pin UDIMM. It runs at 1.2V with CL22 latency and a 2Rx8 rank structure. The kit is validated for the ASUS Prime X299-A II motherboard.

System builders upgrading compatible ASUS X299

This suit builders who need a single 32GB stick to fill one slot on the ASUS Prime X299-A II. It is not for users who require ECC error correction or registered buffering. Buyers with motherboards outside the validated X299-A II platform should verify compatibility before purchase.

Density and rank decide fit

The 32GB capacity uses a 2Rx8 organisation that the memory controller must support. If the board or CPU cannot address this density per rank the module will not post. Confirm the platform accepts 32GB 2Rx8 UDIMMs at DDR4 3200 before ordering.

Questions about this item

How do I install this 288-pin DDR4 UDIMM in my ASUS Prime X299-A II, and what step is often missed?

Align the notch on the module with the slot key, press down firmly until both retention clips click shut, then verify the motherboard detects the full 32GB at 3200 MT/s in BIOS.

What maintenance or replacement will this 1.2 V non-ECC unbuffered module need over time?

No scheduled maintenance is required; if errors appear, run a memory diagnostic and replace the stick if it fails, otherwise it runs for the system's life.

What limit appears first when this CL22 2Rx8 kit runs sustained workloads?

The CAS latency of 22 cycles at 3200 MT/s sets the timing floor, so throughput plateaus before thermal or voltage headroom is reached.
