32 GB DDR4 kit for ASRock Fatal1ty boards

This 32 GB kit contains two 16 GB DDR4 modules rated at 2400 MHz with CL17 timings. It is built for ASRock Fatal1ty AB350 and X370 motherboards including the Gaming K4, Gaming X and Professional Gaming models. The unbuffered non‑ECC DIMMs run at 1.2 V and use major brand chips.

Upgrade from lower capacity or slower DDR4

The kit replaces smaller or slower DDR4 modules to reach the board’s 64 GB maximum across four slots. The jump is worth it when applications need more than 16 GB total or when dual‑channel bandwidth at 2400 MHz improves throughput. Buyers who need more than 64 GB or registered ECC memory cannot use this kit.

Limits of the DDR4 2400 standard on these boards

The memory operates at the DDR4 2400 (PC4 19200) data rate with 17‑17‑17 latency. Four slots cap total capacity at 64 GB, so this 32 GB kit leaves two slots free for future expansion. Systems that require speeds above 2400 MHz or quad‑channel architecture will not benefit from this specification.

Questions about this item

Will the 288-pin DDR4 modules fit the four DIMM slots on my ASRock Fatal1ty AB350 or X370 board?

Yes — each stick is a standard 288-pin DDR4 DIMM, and the supported boards provide four DDR4 slots that accept this form factor.

Which slots should I populate first when installing the 2x16 GB kit, and what is the common mistake?

Install the two modules in the same-coloured slots (usually slots 2 and 4) to run dual-channel; the frequent error is placing them in adjacent slots 1 and 2, which forces single-channel mode.

If I later want the maximum 64 GB, what do I add and what should I match?

Add another 2x16 GB DDR4 2400 CL17 1.2 V unbuffered kit to fill the remaining two slots; matching speed, latency and voltage avoids timing conflicts.
