128GB DDR5 kit for ASRock Z790

This 128GB kit contains four 32GB DDR5 5600 modules built for the ASRock Z790 PG Sonic motherboard. It runs at 1.1V with CL46 timing and uses unbuffered non-ECC 2Rx8 chips. The 288-pin UDIMM form factor fits standard desktop DIMM slots.

Suits Z790 PG Sonic builds only

Buyers with this exact motherboard get a validated four-module kit that matches the board's DDR5 5600 specification. Systems needing ECC, registered modules, lower latency, heat spreaders, or a different pin count should look at other memory.

128GB total capacity in four modules

The kit delivers 128GB across four 32GB sticks, which is the single specification that determines whether the upgrade matches the platform's maximum supported population.

Questions about this item

Does my motherboard need to accept 288-pin DDR5 UDIMMs running at 1.10V for this kit to work?

Yes, the modules are 288-pin DDR5 UDIMMs rated at 1.10V, so the board must support that pin count and voltage.

Will these four 32GB modules fit in the four DDR5 slots of an ASRock Z790 PG Sonic motherboard?

The kit is built for that board and provides four 32GB UDIMMs, one per slot, matching its DDR5 5600 specification.

How can I confirm the memory is running at DDR5 5600 with CL46 after installation?

Check the BIOS or a system information tool — it should report 5600 MT/s and CAS latency 46 for the installed kit.
