64GB DDR4 3200 UDIMM Kit

This 64GB kit contains four 16GB DDR4 modules rated at 3200MT/s with CL22 timings. The sticks are 288-pin unbuffered non-ECC UDIMMs that operate at 1.20V using a 1Rx8 organisation. They are validated for the ASUS Prime X299-A II motherboard.

Suits X299-A II owners adding 64GB

Builders with an ASUS Prime X299-A II who need a matched four-module kit at the board's native 3200 speed will find this set drop-in compatible. Systems that require ECC or registered memory cannot use these unbuffered non-ECC modules. Buyers needing a different capacity or a lower latency bin should look elsewhere.

3200MT/s CL22 at 1.20V

The decisive specification is the DDR4 3200 (PC4-25600) rating combined with CL22 latency at the standard 1.20V operating voltage. This matches the ASUS Prime X299-A II's supported memory profile without overclocking. If your board or CPU memory controller cannot run at 3200MT/s, the kit will downclock to the highest common speed.

Questions about this item

Will the four 16 GB modules need any cleaning or part replacement after installation?

The kit has no heat spreaders and uses standard 1.2 V DDR4 chips, so no scheduled cleaning or component swaps are required once the modules are seated.

What limit appears first when the 64 GB kit runs at 3200 MT/s continuously?

The CL22 latency and 1Rx8 single-rank layout set the timing ceiling; sustained throughput will hit the CAS latency wall before voltage or thermal limits.

How much heat or fan noise does the 1.20 V 288-pin kit add during all-day workloads?

Running at 1.2 V without heat spreaders keeps module temperatures low, adding negligible heat and zero acoustic noise to the system.
