64GB DDR5 Kit for ASRock Z790

This 64GB kit contains two 32GB DDR5 modules built for the ASRock Z790 Lightning WiFi motherboard. It runs at 4800 MT/s with CL40 latency at 1.1V. The unbuffered non-ECC UDIMMs use major OEM chips from Samsung, Micron or Hynix.

Ideal for Z790 builds needing 64GB.

Builders upgrading an ASRock Z790 board to 64GB with standard DDR5 will find this kit validated for that platform. Systems requiring ECC error correction or registered modules cannot use these unbuffered non-ECC sticks.

DDR5 4800 CL40 1.1V 288-pin UDIMM spec

The decisive figure is the DDR5 4800 CL40 1.1V 288-pin UDIMM specification. Your motherboard must support this exact speed, latency, voltage and pin layout for the kit to function correctly.

商品問答

Will this DDR5 4800 kit work alongside older DDR5 modules I keep in the other slots?

The kit is DDR5 4800 CL40 1.10 V 2Rx8; mixing speeds or ranks can force the board to run all sticks at the slowest common setting, so populate the remaining slots with identical spec modules for best stability.

How do I confirm the 64 GB kit is running at 4800 MT/s and CL40 after install?

Open the BIOS or a tool like CPU-Z and verify the memory frequency reads 4800 MT/s (PC5-38400) with CAS latency 40 at 1.10 V.

What exactly ships in the box and is anything else required?

The package contains two 32 GB 288-pin DDR5 UDIMMs — no heat spreaders, no extra cables or brackets; the motherboard and a DDR5-compatible CPU are the only other items needed.
