16 GB DDR4 module for specific ASRock boards

This 16 GB DDR4 DIMM is built for users upgrading an ASRock Fatal1ty AB350 Gaming-ITX/ac, Fatal1ty B450 Gaming-ITX/ac, H110 Pro BTC+ or H270M-ITX/ac motherboard. It arrives new and is validated for those platforms only. Builders with other boards should verify compatibility before purchase.

2400 MHz CL17 timing is the deciding spec

The module runs at 2400 MHz with a CAS latency of 17 and timing of 17-17-17 at 1.2 V. If your board requires a different speed, latency or voltage this stick will not be the correct match. No other timing or voltage options are offered for this part number.

Single 16 GB rank fills one of two slots

Each board listed supports a maximum of 32 GB across two 288-pin slots, so this 2Rx8 module occupies one slot and leaves room for a second 16 GB stick to reach the limit. Buyers needing more than 32 GB total capacity or more than two modules must choose a different platform.

Questions about this item

Will the 2400 MHz speed run at full rate on the ASRock Fatal1ty AB350 Gaming-ITX/ac?

The module is rated at DDR4 2400 (PC4 19200). The board supports DDR4 up to 2400 MHz, so the stick will operate at its rated speed without manual tuning.

Does the 288-pin DDR4 DIMM fit the four memory slots on the H110 Pro BTC+?

The H110 Pro BTC+ has two DDR4 DIMM slots, each accepting 288-pin unbuffered modules. This single 16 GB stick occupies one slot and leaves the second free for another kit.

What clearance does the module need since it has no heat spreader?

Without a heat spreader the PCB sits at standard low-profile height. It clears most CPU coolers and fits the compact ITX layouts of the listed ASRock boards without interference.
