Capacity and Compatibility

This 128GB kit contains four 32GB DDR5 UDIMMs rated at 4800MT/s with CL40 latency and 1.10V operation. It is built for the ASRock Z790 Lightning WiFi motherboard and uses unbuffered non-ECC modules with a 2Rx8 organisation.

Who This Suits

Builders upgrading that specific ASRock board to the full four-slot population will get the listed capacity and speed without configuration changes. Buyers who need ECC error correction or registered modules should look elsewhere, as this kit provides neither.

Deciding Specification

The 288-pin DDR5 UDIMM form factor with 1.10V voltage and CL40 timing at 4800MT/s is the single detail that determines whether the kit will install and run on the target motherboard.

商品問答

Will the 288-pin DDR5 UDIMM modules fit the four DIMM slots on the ASRock Z790 Lightning WiFi motherboard?

Yes, the kit provides four 288-pin DDR5 UDIMM modules designed for the four DIMM slots on the ASRock Z790 Lightning WiFi motherboard.

What is the correct slot order when installing all four 32GB modules on this motherboard?

Populate the two slots of the primary memory channel first, usually labelled DDR5_A1 and DDR5_B1, then add the remaining two modules to the second channel slots.

When should the 2Rx8 DDR5 modules be replaced?

Replace a module only if a memory diagnostic reports persistent errors on that specific stick; otherwise the kit is rated for continuous operation at 1.10V.
