System-specific DDR5 kit for ASUS ROG Strix Z890-E

This 64GB kit contains four 16GB unbuffered UDIMMs built for the ASUS ROG Strix Z890-E Gaming WiFi motherboard. It runs at DDR5 4800 with CL40 timings at 1.10V. The modules use major OEM chips from Samsung, Micron or Hynix in a 1Rx8 layout. They target builders who need a validated upgrade for this exact board.

Four-module kit fills all four slots

The package delivers the full 64GB in a matched set of four 288-pin modules. Buyers receive a single kit rated PC5-38400 with no extra cables, software or heat spreaders included. The 1Rx8 organisation and non-ECC design keep the configuration straightforward. Systems needing ECC, registered DIMMs or a different capacity must look elsewhere.

Plain green PCB fits standard DDR5 slots

Without a heat spreader the modules sit at standard height, leaving maximum clearance for large CPU coolers. Gold contacts on the 288-pin edge connector ensure reliable seating in the board's four DDR5 slots. The 1.10V operating voltage matches the platform's default specification. Builds that require tall heat spreaders or RGB lighting will not find them here.

Questions about this item

Will the 288-pin UDIMM modules need any periodic cleaning or component replacement after installation?

The modules have no moving parts and no heat spreader, so they require no scheduled maintenance or component replacement once seated in the motherboard slots.

What limit appears first when the four 1Rx8 modules run at DDR5 4800 continuously?

The CL40 latency at 1.10 V sets the timing boundary; sustained loads will hit that latency ceiling before any voltage or thermal throttle engages.

How much heat and noise do the 64 GB kits produce when the system runs all day?

With no heat spreader and a low 1.10 V operating voltage, the sticks generate minimal heat and zero audible noise during continuous operation.
