64 GB DDR4 3200 Kit for ASUS Prime Boards

This NEMIX RAM kit delivers 64 GB of DDR4 3200 memory in a matched pair of 32 GB UDIMM modules. It is built for desktop PCs using ASUS Prime B760M-K D4, Prime H610I-PLUS D4-CSM or Prime H610M-E D4 motherboards. The unbuffered, non-ECC design suits standard consumer workloads and gaming rigs that need a straightforward capacity increase.

DDR4 3200 CL22 Speed and Voltage Limits

The modules run at DDR4 3200 (PC4-25600) with a CAS latency of CL22 and a fixed 1.2 V operating voltage. The 288-pin DDR4 interface caps the maximum data rate at this frequency, so the system will not exceed the rated speed even if the CPU or chipset supports higher bins. The 2Rx8 organisation is a physical constraint of each 32 GB rank and cannot be altered by firmware.

Check Motherboard Model

Verify that your board is one of the three ASUS Prime models listed in the compatibility data. Confirm the motherboard has at least two free DDR4 UDIMM slots to accept the pair. Ensure the platform accepts non-ECC, unbuffered memory at 1.2 V, as registered or ECC modules are not interchangeable with this kit.

Questions about this item

Should I pick the 2x32GB kit or a single 64GB module?

This product is sold only as a 2x32GB kit, giving 64GB total across two modules.

What does the 3200 speed mean once installed in my ASUS board?

The modules run at DDR4 3200 (PC4-25600) with CL22 latency at 1.2V, matching the board's supported speed.

How does the 288-pin DDR4 interface limit what I can do?

The 288-pin UDIMM form factor fits only DDR4 desktop slots; it cannot be used in DDR5 or laptop SO-DIMM sockets.
