Targeted DDR4 Kit

This 16 GB kit contains two 8 GB DDR4 modules rated at 2400 MHz with CL17 timings. It is validated for Gigabyte Z390 AORUS and Gaming motherboards including Elite, Extreme, Master, PRO WiFi, Ultra, SLI and X models. The unbuffered, non-ECC DIMMs operate at 1.2 V using major-brand chipsets.

DDR4 2400 Practical Limits

DDR4 2400 transfers data at 19200 MB/s per module, so the dual-channel pair can saturate typical mainstream workloads. The platform maximum is 64 GB across four sockets, meaning this half-populated kit leaves room for a second identical pair. Builders who need more storage than 64 GB or who require ECC error correction cannot use these sticks.

Plain Green PCB Build

Modules lack a heat spreader, exposing the bare green PCB and major-brand chips for direct airflow from CPU coolers. Standard 288-pin DIMM keying ensures a firm seat in any Z390 slot without clearance conflicts. The two-piece pack simplifies dual-channel population; buyers who want RGB lighting or tall heatsinks must look elsewhere.

Questions about this item

Should I choose the 16 GB kit or the 8 GB modules individually for my Z390 AORUS board?

This listing is a single 16 GB kit containing two matched 8 GB modules; buying the kit ensures dual-channel operation and validated compatibility with the listed Z390 AORUS models.

What does the DDR4-2400 rating mean once the modules are installed in my Z390 AORUS motherboard?

The modules run at 2400 MT/s with CL17 timing at 1.2 V, delivering the standard DDR4-2400 data rate supported by the Z390 memory controller.

The kit is 288-pin DDR4 — does that limit the total memory I can install on my Z390 AORUS board?

The motherboard has four 288-pin DDR4 sockets and supports up to 64 GB total; this 16 GB kit occupies two slots, leaving two free for future expansion.
