ASRock Z790 PG Riptide Kit

This 32GB kit contains two 16GB DDR5 UDIMMs validated for the ASRock Z790 PG Riptide motherboard. The modules run at 4800 MT/s with a CL40 latency at 1.1V. They use major OEM chips and are non-ECC unbuffered.

Builders Matching This Board

The kit suits anyone upgrading or populating an ASRock Z790 PG Riptide system with guaranteed compatibility. Buyers needing ECC error correction or registered modules should look elsewhere, as this kit provides neither.

PC5-38400 Speed Rating

The decisive spec is the PC5-38400 rating, which confirms DDR5 4800 operation for this platform. Systems requiring a different data rate or voltage will not accept these modules.

商品問答

Will these 288-pin DDR5 modules fit the four slots on my ASRock Z790 PG Riptide?

Yes — the kit is a 288-pin DDR5 UDIMM and the board uses the same DDR5 slot layout, so each 16 GB stick seats directly in any of the four DIMM sockets.

Do I need to enable XMP or EXPO in the BIOS after inserting the sticks, or will they run at 4800 CL40 automatically?

The modules are rated 4800 MT/s CL40 at 1.10 V JEDEC standard; they will boot at that speed without any manual profile, though you can still enable XMP if the board offers a higher profile.

Since there is no heat spreader, will I need extra airflow or a replacement kit later?

The bare PCB runs at standard 1.10 V DDR5 voltage; normal case airflow is sufficient, and the modules carry a lifetime replacement warranty if a stick ever fails.
