64GB DDR4 Kit for ASUS Motherboards

This 64GB kit contains four 16GB DDR4 UDIMM modules rated at 3200MHz with CL22 latency and 1.2V operation. It is built for desktop PCs using ASUS Prime B660, B760, H770, Z790M or B560 motherboards. The unbuffered, non-ECC design suits standard consumer platforms.

Sustained Load Stability

Modules are stress-tested under load to maintain reliability during extended workloads. The 1Rx8 organisation and major-brand Samsung, Micron or Hynix chips help deliver consistent throughput without heat spreaders. JEDEC-standard 1.2V voltage keeps power draw predictable during long sessions.

Pre-Installation Checks

Verify your motherboard supports DDR4 3200MHz UDIMM memory and has four free 288-pin slots for the full kit. Confirm the BIOS is updated for the listed ASUS Prime series boards. Ensure the operating system can address 64GB of system memory.

Questions about this item

Does the 1.2 V DDR4 kit run hot or draw much power during all-day workloads?

At 1.2 V the four 16 GB modules operate at standard DDR4 voltage, so heat output and power draw stay low even under continuous load.

Which motherboard must I already own for this 288-pin UDIMM kit to work?

The kit is validated for ASUS Prime B660, B760, H770, Z790M and B560 boards; any of those with four DDR4 slots will accept the 64 GB kit.

Will the CL22 3200 MHz modules slow down an older DDR4 system I keep?

The memory runs at 3200 MHz CL22; on an older board it will simply drop to the highest speed that platform supports without instability.
