Compatible DDR5 upgrade for ASRock Z790 PG Riptide

This 16 GB DDR5 4800 module is validated for the ASRock Z790 PG Riptide motherboard. It runs at 1.10 V with CL40 latency in a single 1Rx8 rank. The unbuffered non-ECC UDIMM uses major OEM chips from Samsung Micron or Hynix. No heat spreader is fitted.

Builders matching this exact board and spec

Suits owners of the ASRock Z790 PG Riptide who need a 16 GB DDR5 4800 CL40 1.10 V UDIMM. Not suited for systems requiring ECC error correction registered modules or a different voltage. Buyers with other motherboards should verify their qualified vendor list before purchasing.

DDR5 4800 CL40 at 1.10 V

The decisive specification is the DDR5 4800 speed rated at CL40 with 1.10 V operation in a 288-pin UDIMM form factor. If your platform demands this exact speed latency and voltage combination this module fits. If the board requires a different data rate timing or voltage choose another part.

Questions about this item

Does the module ship alone or as a kit with extra parts?

The package contains a single 16GB DDR5 4800 UDIMM rated CL40 at 1.1V; no additional components are included.

Should I pick a different speed or latency for the ASRock Z790 PG Riptide?

This 4800MHz CL40 module matches the board's native DDR5 speed and is validated for that platform; higher speeds would require manual tuning.

Will the 4800MHz rating run at that speed automatically on the Z790 PG Riptide?

Yes, the board's default DDR5 profile sets 4800MHz CL40 at 1.1V, so the module operates at its rated frequency without BIOS changes.
