ASUS-compatible DDR4 3200 64GB kit

This 64GB kit contains four 16GB DDR4 UDIMM modules rated at 3200MHz with CL22 latency and 1.2V operation. The memory is unbuffered, non-ECC and uses a 1Rx8 organisation. It is built from major OEM DRAM chips and carries a 288-pin interface. The kit targets owners of the listed ASUS Prime B450, B550 and X570 motherboards who want a straightforward capacity increase.

Buyers needing ECC or registered DIMMs

This product suits desktop users who want a matched 64GB set for the named ASUS boards and who do not require error correction or registered signalling. It will not meet the needs of servers or workstations that demand ECC protection, registered modules or voltages other than 1.2V. Builders using platforms outside the specified compatibility list should verify support before purchasing.

288-pin DDR4 UDIMM form factor

The modules use the standard 288-pin DDR4 UDIMM layout, which is the single physical specification that determines whether they fit the target motherboards. Only boards accepting DDR4 UDIMM memory at 1.2V can use this kit; systems requiring SO-DIMM, DDR5 or a different pin count cannot accept these modules.

Questions about this item

Do I need four free 288-pin DDR4 UDIMM slots on my motherboard to install this 64 GB kit?

Yes — the kit contains four 16 GB modules, so four empty 288-pin DDR4 UDIMM slots are required.

Will these CL22 3200 MT/s modules run at their rated speed on an ASUS PRIME B450M-A or B550M-A board?

The kit is validated for ASUS PRIME B450M-A, B550M-A and X570-PRO boards; enable XMP or DOCP in the BIOS to reach 3200 MT/s at CL22.

How can I confirm the kit is running at 3200 MT/s with CL22 timings after installation?

Open Task Manager → Performance → Memory or run CPU-Z; both display the active DRAM frequency and CAS latency.
