128GB DDR5 4800 kit for ASRock Z790

This 128GB kit contains four 32GB DDR5 4800 UDIMM modules built for ASRock Z790 Taichi, Taichi Carrara and Taichi Lite motherboards. Each stick runs at 1.1V with CL40 latency and a 2Rx8 layout. The kit is new and unbuffered, non-ECC memory designed for desktop PC upgrades.

Not for laptops or boards needing ECC

This kit suits desktop builders upgrading compatible ASRock Z790 boards with four UDIMM slots. It will not work in laptops, servers or any system that requires registered or ECC memory. Buyers needing heat spreaders or lower CAS latency should look elsewhere.

DDR5 4800 288-pin UDIMM interface

The modules use a standard 288-pin DDR5 UDIMM connector operating at 4800 MT/s (PC5-38400). This single specification determines whether the kit fits your motherboard and memory controller. Confirm your board supports DDR5 4800 unbuffered non-ECC UDIMMs before purchase.

Questions about this item

Should I choose the 4 × 32 GB kit or a different capacity for my ASRock Z790 board?

This kit provides 128 GB in four 32 GB modules, filling all four DIMM slots on Z790 Taichi, Carrara and Lite boards for maximum supported capacity.

What does DDR5 4800 with CL40 actually deliver in a desktop system?

The modules run at 4800 MT/s with 40-cycle latency at 1.10 V, giving standard JEDEC bandwidth without overclocking.

Will the 288-pin UDIMM interface limit speed or capacity on my motherboard?

The 288-pin DDR5 UDIMM form factor is the native desktop standard; the board's memory controller caps transfer rate and total capacity, not the module connector.
