16GB DDR4 3200 UDIMM for ASUS Prime X299-A II

This 16GB DDR4 3200 module is built for the ASUS Prime X299-A II motherboard. It runs at 1.20V with CL22 latency and uses a single-rank 1Rx8 layout on a standard 288-pin unbuffered DIMM. No heat spreader is fitted.

Suits single-slot capacity upgrades on X299

Buyers who need ECC error correction, registered modules, lower CAS latency, or multi-kit matched sets should choose a different specification. This part is a single unbuffered non-ECC stick validated for the named board.

DDR4 3200 PC4-25600 speed rating

The module operates at DDR4 3200 (PC4-25600) with CL22 timing at 1.20V. This speed and voltage combination decides whether the board will train the memory at the rated frequency without manual tuning.

Questions about this item

Will the 1.20 V 3200 MHz module run cool and quiet during all-day workloads?

Operating at standard 1.20 V with no heat spreader, this DDR4 UDIMM relies on case airflow and produces no fan noise of its own.

What motherboard slot and memory type must my system already provide for this stick to work?

A 288-pin DDR4 UDIMM slot on an ASUS Prime X299-A II board is required; the module is non-ECC and unbuffered.

How will this CL22 3200 MHz DIMM behave when installed next to slower DDR4 modules already in the board?

The memory controller will run all populated slots at the lowest common speed and latency, so this module will downclock to match the slower sticks.
