16 GB DDR4 module for Z390 boards

This 16 GB DDR4 2400 CL17 DIMM is built for MSI MAG Z390 Tomahawk, MEG Z390 ACE, MEG Z390 GODLIKE and MPG Z390 Gaming Edge AC motherboards. It runs at 1.2 V without ECC or buffering, using a 2Rx8 layout on a 288-pin stick. Buyers who need ECC error correction or registered modules should look elsewhere.

Thermals noise and power

Operating at the standard 1.2 V, the module draws minimal power and produces little heat, so it runs silently without a heat spreader. The unbuffered design keeps electrical load low on the memory controller during typical desktop workloads. No active cooling or extra airflow is required for normal operation.

Build and daily use

The bare green PCB fits any standard 288-pin DDR4 slot, leaving clearance for large CPU coolers. A single stick populates one of four sockets, allowing the platform to reach 64 GB total capacity when all slots are filled. The 1-piece kit simplifies upgrades for users adding memory to an existing configuration.

Questions about this item

How do I install the 288-pin DDR4 DIMM on my MSI Z390 board, and what step is often missed?

Align the notch on the 288-pin DDR4 module with the slot key, press down firmly until both retention clips click shut, then verify in BIOS that the memory runs at 2400 MHz CL17; the step many miss is fully seating both ends so the clips engage automatically.

What maintenance or replacement will this 16GB DDR4 2400 CL17 module need over time?

No scheduled maintenance is required; keep the system free of dust and ensure the 1.2V power delivery remains stable. If errors appear, the module carries a limited lifetime warranty from Computer Memory Solutions for repair or exchange.

What limit appears first when this 2Rx8 DDR4 2400 kit runs sustained workloads on a Z390 platform?

The 2400 MHz CL17 timing and 1.2V JEDEC voltage set the performance ceiling; with four slots supporting up to 64 GB total, bandwidth and latency remain fixed at the rated 19200 MT/s, so throughput caps out before thermal throttling becomes a factor.
