16 GB DDR5 UDIMM for ASUS ROG Strix Z890-I Gaming

This 16 GB DDR5 4800 module is built specifically for the ASUS ROG Strix Z890-I Gaming WiFi motherboard. It targets builders who need a single, validated stick to expand or replace memory in that platform. The kit delivers 1Rx8 organisation at CL40 latency without ECC or buffering.

Verify DDR5 slot availability

Before ordering, confirm the board has a free 288-pin DDR5 slot and that the firmware supports a 16 GB non-ECC unbuffered DIMM. The motherboard manual will state the maximum capacity per slot and any population rules for single-rank modules. No other memory generation will fit the DDR5 socket.

No heat spreader means low profile

The module ships without a heat spreader, keeping the height minimal for tight CPU cooler clearances. Standard 288-pin gold-edge connectors seat with normal insertion force and the 1.10 V operating voltage matches the DDR5 baseline. Chips are sourced from major OEM suppliers and each stick is stress tested before shipping.

Questions about this item

Does the module include a heat spreader or must I buy one separately?

The module ships without a heat spreader and the package contains only the single 16 GB DDR5 UDIMM; no extra cooler is included.

Is the 4800 MHz CL40 version the only kit available for this board?

This listing is a single 16 GB DDR5 4800 CL40 stick; other speeds or capacities would be separate part numbers not covered here.

Will the rated 4800 MT/s transfer rate run automatically on the Z890-I?

The board will boot at JEDEC 4800 MT/s by default; enabling XMP or EXPO in BIOS is required only if a higher-speed profile exists on the module.
