NEMIX 64GB DDR4 3200 UDIMM Kit

This 64GB kit contains two 32GB DDR4 3200 modules rated at CL22 and 1.20V. They are non-ECC unbuffered UDIMMs built with major OEM chips from Samsung, Micron or Hynix and use the standard 288-pin layout for desktop platforms.

Suitable for ASUS Prime X299-A II owners adding 64GB

The kit is validated for the ASUS Prime X299-A II motherboard and suits users expanding that specific board to 64GB. It is not ECC memory, so it will not meet the requirements of systems that demand error-correcting code. Builders needing registered or load-reduced modules should look elsewhere.

Check motherboard manual for slot population rules

Before ordering, confirm your board accepts 2Rx8 density at 3200 MT/s and that the two DIMM slots you plan to use support this configuration. Verify the BIOS is updated to a version that enables the rated speed and timing. Ensure the platform uses DDR4 and not a different generation.

Questions about this item

Does this 64 GB kit require an ASUS Prime X299-A II motherboard to operate?

The kit is validated for the ASUS Prime X299-A II and uses standard 288-pin DDR4 UDIMM form factor, so it will fit any desktop board that accepts DDR4 3200 non-ECC unbuffered memory.

Can I mix these 2Rx8 CL22 modules with older single-rank DDR4 sticks already in my system?

Mixing ranks and latencies is possible but the motherboard will run all modules at the speed and timing of the slowest installed kit.

How do I confirm the 3200 MT/s data rate and CL22 timings are active after installation?

Check the memory tab in CPU-Z or the BIOS memory information screen; both should report 3200 MT/s and CL22 for the new modules.
