ASRock Z790 PG Sonic DDR5 Kit

This 64GB kit contains four 16GB DDR5 UDIMM modules built for the ASRock Z790 PG Sonic motherboard. It targets desktop builders who want a matched set that installs without manual tuning.

DDR5 5600 PC5-44800 interface limits

The modules run at 5600 MT/s with CL46 latency at the standard 1.1V DDR5 voltage. Bandwidth is capped by the JEDEC DDR5 specification; tighter timings or higher frequencies are not supported by these sticks.

64GB capacity and headroom

Four ranks of 1Rx8 Samsung, Micron or Hynix chips deliver 64GB total, enough for heavy multitasking and content workloads. Systems needing more than four modules or ECC error correction will exceed this kit.

Questions about this item

Should I choose the 64GB kit with four 16GB modules or a different capacity for the ASRock Z790 PG Sonic?

This kit provides 64GB total using four 16GB modules; the board has four slots so the kit fills every slot and leaves no room for extra sticks.

What does the 5600 speed rating actually deliver once the memory is installed in the Z790 PG Sonic?

The modules run at DDR5 5600 with a CAS latency of CL46 at 1.10V, giving a PC5-44800 bandwidth rating for the system.

How does the 288-pin DDR5 UDIMM interface limit what I can do with this kit?

The 288-pin DDR5 UDIMM form factor fits only DDR5 desktop slots; the four-slot kit occupies every channel on the Z790 board.
