Targeted DDR5 kit for ASRock Z790

This 64 GB kit contains two 32 GB unbuffered UDIMMs rated at DDR5 4800 with CL40 timings. It is built for desktop PCs that use the specified ASRock motherboards and need a straight-forward capacity increase. No heat spreaders are included, keeping the modules low-profile for tight CPU cooler clearances.

Standard 288-pin DDR5 UDIMM form factor

Each module uses a 2Rx8 organisation and runs at the JEDEC 1.10 V baseline, so no manual voltage tuning is required. The plain green PCB fits any desktop slot wired for DDR5, and the dual-rank layout helps fill four-channel controllers efficiently. Installation follows the usual UDIMM procedure described in the motherboard manual.

Two-module kit validated for the listed ASRock

The package delivers exactly the 64 GB (2 x 32 GB) configuration tested for compatibility with the Z790 LiveMixer and B650 LiveMixer broadcasting motherboards. Buyers who need ECC error correction, registered signalling, or speeds above the 4800 MT/s JEDEC base should look for a different module type.

Questions sur cet article

What DDR5 speed does this 64 GB kit run at, and what does the PC5-38400 rating mean for bandwidth?

The kit is rated DDR5 4800 (PC5-38400), so the standard's peak transfer rate is 38400 MB/s; actual throughput depends on the motherboard's memory controller and BIOS settings.

Will these 288-pin UDIMMs fit in the four DIMM slots on my ASRock Z790 or B650 LiveMixer board?

Yes, each module is a standard 288-pin DDR5 UDIMM and the kit contains two 32 GB sticks, so they install directly into any DDR5 desktop DIMM slot on those motherboards.

Do I need to enable XMP or EXPO in the BIOS to reach the rated CL40 4800 speed, or will it run at that speed automatically?

DDR5 defaults to 4800 MT/s at 1.1 V without any profile; the modules will run at CL40 4800 automatically, though you can still enable an XMP/EXPO profile if your board offers one for tighter timings.
