64GB DDR5 Kit for ASRock Z790 Riptide
This NEMIX RAM kit provides 64GB of DDR5 memory across four 16GB modules. It is built for the ASRock Z790 PG Riptide motherboard and runs at 4800MHz with a CL40 latency. The unbuffered, non-ECC UDIMMs operate at the standard 1.1V. Builders upgrading this specific board can install the matched set directly.
Suits single-board upgrades; not for mixed kits
The kit targets owners of the ASRock Z790 PG Riptide who want a validated four-module set. It fits standard desktop DIMM slots and requires no heat spreader clearance. Builders mixing this memory with existing modules of different speed, latency or voltage should look elsewhere, as stability cannot be guaranteed across mismatched kits.
4800MHz CL40 at 1.1V decides fit
The modules run at DDR5 4800 (PC5-38400) with a CAS latency of 40 and a 1.10V operating voltage. This exact speed and timing combination is what the motherboard expects for plug-and-play operation. If your build demands a different data rate or lower latency, this kit will not meet that requirement.

Questions about this item
Will the 4800 MHz DDR5 modules run at full speed alongside older DDR5 sticks I keep in the other slots?
Mixing memory kits with different speeds, latencies or voltage can prevent the system from reaching the rated 4800 MT/s and CL40 timings. For best stability, populate all four slots with this matched 64 GB kit.
How can I confirm the kit is running at 4800 MT/s and CL40 after installation?
Enter the UEFI BIOS and open the memory information screen; it should report 4800 MT/s (PC5-38400) and CL40. CPU-Z or HWiNFO in Windows will show the same figures on the SPD and Memory tabs.
Does the package include only the four 16 GB UDIMMs or are extra items such as a screwdriver or thermal pads supplied?
The box contains only the four 16 GB 288-pin DDR5 UDIMM modules. No tools, screws, thermal pads or additional accessories are included.
