48 GB DDR5 module for ASRock Z790 PG Riptide

This 48 GB DDR5 4800 UDIMM is validated for the ASRock Z790 PG Riptide motherboard. It targets builders upgrading that specific platform with a single high-capacity stick. The non-ECC unbuffered design matches standard desktop requirements. No heat spreader is included on the module.

Capacity headroom at CL40 1.1 V

The 48 GB density provides substantial memory space for multitasking and large datasets on a single 288-pin slot. Dual-rank 2Rx8 organisation supports the rated 4800 MT/s speed at CL40 latency. The 1.10 V operating voltage aligns with the base DDR5 specification. Systems requiring ECC or registered memory cannot use this module.

Build integration with single-slot design

A single 288-pin UDIMM occupies one DIMM slot leaving remaining channels free for future expansion. The PC5-38400 rating ensures compatibility with the board's DDR5 controller at default JEDEC settings. No additional cooling hardware is mandated by the module itself. Buyers needing ECC functionality or lower latency kits should look elsewhere.

Questions about this item

Will this 48GB DDR5 4800 CL40 module run alongside my existing DDR5 memory on the ASRock Z790 PG Riptide?

The Z790 PG Riptide supports DDR5 only, so this 1.1V CL40 UDIMM will work with other DDR5 modules; the board will train all installed sticks to a common speed and timing.

How can I confirm the module is running at DDR5 4800 with CL40 after installation?

Enter the UEFI or use a tool like CPU-Z to verify the memory reports 4800 MT/s, CAS latency 40, 1.10V and 2Rx8 organisation.

What is included in the package and do I need any extra parts to install it?

The box contains one 48GB 288-pin DDR5 UDIMM; no heat spreader, cables or additional hardware are supplied or required for installation.
