8GB DDR4 upgrade for select ASUS boards

This 8 GB DDR4-2400 module targets owners of ASUS Prime X470-PRO, Prime Z390-A, Prime Z390-P or WS Z390 PRO motherboards who need a straightforward capacity increase. It is an unbuffered, non-ECC DIMM built with major-brand chips and tested for the listed platforms. Builders using other chipsets or requiring registered memory should look elsewhere.

Capacity and headroom for everyday workloads

The single 8 GB stick runs at 2400 MHz with CL17 timings and 1.2 V, delivering 19200 MB/s bandwidth that handles office suites, web browsing and light content creation comfortably. Dual-rank 2Rx8 organisation helps density, but the kit provides only one module, so total system memory stops at 8 GB unless additional slots are populated. The supported platforms max out at 64 GB across four sockets, leaving headroom for future expansion.

CL17 latency at DDR4-2400 decides fit

CAS latency of 17 at 2400 MHz is the critical timing figure; systems tuned for tighter timings may not gain stability from this module. Voltage is fixed at 1.2 V with no heat spreader, so cooling relies on case airflow alone. Verify the motherboard model matches the qualified list before purchase, as compatibility is guaranteed only for the four specified boards.

Questions about this item

Will this DDR4 2400 CL17 1.2V DIMM run stably alongside my existing slower DDR4 modules in the Prime X470-PRO?

The module is rated for DDR4 2400 at CL17 and 1.2V; the motherboard will automatically down-clock all installed sticks to the lowest common speed and timings, so mixed kits will operate at the slowest module’s settings.

How can I confirm the 8GB stick is recognised at 2400 MHz after installing it in a Prime Z390-A?

Enter the BIOS or use a tool such as CPU-Z; the memory tab should show 2400 MHz (PC4-19200) with 17-17-17 timings and 1.2V for the new DIMM.

Does the package contain only the single 288-pin DIMM or are screws, cables or a heat spreader included?

The box contains one 8GB 288-pin DDR4 DIMM; no heat spreader, screws, cables or additional accessories are supplied.
