32 GB DDR4 kit for ASRock Z390 boards

This 32 GB kit contains four 8 GB unbuffered DIMMs rated at DDR4 2400 with CL17 timings and 1.2 V operation. It targets builders upgrading an ASRock Z390 Phantom Gaming SLI/ac, Pro4 or Taichi motherboard to the platform's 64 GB maximum capacity.

DDR4 2400 bandwidth ceiling on Z390

The Z390 memory controller officially supports DDR4 2400 without overclocking, so this kit runs at the highest guaranteed JEDEC speed for the platform. Faster modules will drop to 2400 unless the BIOS enables XMP and the silicon allows it, which is not assured on every board.

Four-slot population requires matched kit

Installing all four sticks fills every DIMM slot on the supported boards, so a single matched 4 x 8 GB kit avoids timing mismatches that cause boot failures. Mixing with existing modules often forces the system to run at lower speeds or prevents POST entirely.

Questions sur cet article

Should I pick the 32GB four-stick kit or a different capacity for my Z390 board?

This kit provides 32GB across four 8GB modules, filling all four DIMM slots on the Z390 Phantom Gaming SLI/ac, Pro4 or Taichi. The board maximum is 64GB, so if you need more capacity later you would have to replace the entire kit.

What does the DDR4 2400 speed rating mean once the modules are installed?

The memory runs at 2400MHz with CL17 timings (17-17-17) at 1.2V, delivering PC4 19200 bandwidth. The Z390 chipset will operate the kit at this rated speed without manual overclocking.

Does the 288-pin DDR4 interface limit anything on these ASRock Z390 boards?

The 288-pin DDR4 DIMMs fit the four native slots on the Z390 Phantom Gaming SLI/ac, Pro4 and Taichi. The platform caps total memory at 64GB and runs the kit at its rated 2400MHz CL17 without further restriction.
