Capacity and configuration

This NEMIX RAM kit provides 64GB of DDR5 memory in a matched pair of 32GB modules. It runs at 4800 MT/s with CL40 timings and a 1.10V operating voltage. The 288-pin UDIMM form factor fits standard desktop DIMM slots and the kit is validated for the ASUS ROG Strix Z890-F Gaming WiFi motherboard.

Compatibility fit

The kit suits builders upgrading that specific ASUS motherboard with a 64GB dual-channel configuration using unbuffered non-ECC DDR5. It does not suit systems that require ECC or registered modules. Buyers who need a heat spreader should look elsewhere, as these modules ship without one. The 2Rx8 organisation is fixed and cannot be changed.

Deciding specification

The motherboard-specific validation for the ASUS ROG Strix Z890-F Gaming WiFi is the single specification that decides fit. If your board is not that exact model, the kit may not boot or may run at reduced settings. Confirm the motherboard model before ordering.

Questions about this item

Should I choose this 64GB kit of two 32GB modules or a single 32GB stick for my ASUS ROG Strix Z890-F Gaming motherboard?

The 2 x 32GB kit enables dual-channel operation on the Z890 board, doubling memory bandwidth compared to a single module and filling two of the four UDIMM slots for balanced performance.

What does the DDR5 4800 speed rating mean once the kit is installed in the system?

The modules run at 4800 MT/s with CL40 latency at the standard 1.10V, delivering PC5-38400 bandwidth for desktop workloads without requiring manual overclocking or XMP profiles.

How does the 288-pin DDR5 UDIMM interface limit what this memory can do in practice?

The unbuffered 288-pin DDR5 UDIMM design is built for consumer desktop motherboards like the Z890-F Gaming, supports 2Rx8 organisation, and cannot be used in platforms that require registered or ECC DIMMs.
