16 GB DDR5 UDIMM for ASUS Z890 APEX

This 16 GB DDR5 module is built for the ASUS ROG Maximus Z890 APEX motherboard. It targets builders and IT professionals who need a single, validated stick for that platform.

No heat spreader simplifies tight layouts

The bare PCB allows installation in cramped DIMM slots where tall spreaders would interfere with large coolers or custom tubing. Unbuffered, non-ECC operation keeps latency low for desktop workloads.

4800 MT/s CL40 at 1.1 V gives baseline headroom

The JEDEC-standard speed handles everyday multitasking and light content creation without manual tuning. Heavy rendering or memory-bound compute will saturate the single 1Rx8 rank before faster kits would.

Questions about this item

Does the single 1Rx8 rank limit future capacity upgrades on the four-slot Z890 APEX board?

The module is a single 1Rx8 16 GB stick, leaving three empty DIMM slots on the Z890 APEX so you can add more identical kits later without replacing this one.

Will the CL40 latency at DDR5 4800 become the bottleneck before the CPU hits its thermal ceiling?

At DDR5 4800 CL40 the memory subsystem typically saturates first in latency-sensitive workloads, while the processor still has thermal headroom.

How much extra heat does the 1.1 V module add when the system runs all day without a heat spreader?

Operating at 1.1 V the bare PCB module draws minimal power and relies on case airflow; it adds only a few watts of heat during continuous operation.
