192GB DDR5 Kit for ASRock Motherboards

This NEMIX RAM kit delivers 192GB across four 48GB DDR5 UDIMM modules. It runs at 4800MHz with CL40 latency at 1.10V. The unbuffered, non-ECC design targets desktop platforms using the Z790 or B650 LiveMixer chipsets.

Who This Suits and Who Should Look Elsewhere

Builders upgrading an ASRock Z790 LiveMixer or B650 LiveMixer board to the maximum 192GB capacity will find a matched, tested kit here. Users needing ECC error correction, registered modules, or speeds above 4800MHz cannot use this memory.

The Specification That Decides Fit

The kit uses 2Rx8 organisation on 288-pin DDR5 UDIMMs. Your motherboard must support four ranks per channel at 4800MHz without registered or ECC buffers for this part to function.

Questions about this item

Will this 192GB DDR5 4800 CL40 kit run stably alongside my existing DDR5 modules at 1.10V?

The kit is rated for 1.10V and CL40 at 4800 MT/s; mixing modules with different voltages or timings can cause instability, so matching specs is recommended.

How can I verify the 4x48GB kit is running at 4800 MT/s with CL40 after installation?

Check the memory speed and latency in the BIOS or UEFI, or use a system-information tool such as CPU-Z to confirm 4800 MT/s and CL40 timings.

Does the package include only the four 48GB UDIMMs or are any cables or brackets supplied?

The box contains the 192GB (4x48GB) DDR5 4800 UDIMM kit only; no cables, brackets or additional accessories are included.
