32 GB DDR5 UDIMM for ASRock Z790 PG Riptide

This 32 GB DDR5 UDIMM is built for the ASRock Z790 PG Riptide motherboard. It suits desktop builders who need a single 32 GB module to expand system memory. The unbuffered non-ECC design matches standard consumer platform requirements.

Sustained load behaviour without heat spreader

Operating at 1.10 V and CL40, the module runs at the JEDEC DDR5 4800 baseline. Without a heat spreader, thermals rely on case airflow during extended workloads. Major OEM chips from Samsung Micron or Hynix are stress tested under load for stability.

288 pin 2Rx8 organisation decides fit

The 288 pin 2Rx8 layout and PC5 38400 rating determine electrical and physical compatibility with the target board. Builders needing ECC registered modules or a different rank configuration must choose another part.

Perguntas sobre este artigo

Does the 1.1 V operating voltage keep the 32 GB module cool during all-day workloads?

The 1.10 V standard voltage and unbuffered DDR5 design run at stock JEDEC levels, so heat output stays within normal limits for continuous desktop use.

What motherboard slot and memory controller does my system need for this 288-pin UDIMM to function?

A desktop board with a DDR5 memory controller and a 288-pin UDIMM slot is required; the module is validated for the ASRock Z790 PG Riptide.

Will this single-rank 2Rx8 stick work in a four-slot board where I keep two older DDR5 modules?

Yes, the 2Rx8 rank structure and CL40 timing follow standard DDR5 specs, allowing mixed-population operation when the motherboard trains all modules to a common speed.
