Capacity and compatibility

This kit provides 192 GB of DDR5 memory in four 48 GB modules. It is built for the ASRock Z790 PG Riptide motherboard and uses standard 288-pin UDIMM form factor. The modules are non-ECC and unbuffered for desktop use.

Sustained workload behaviour

Each module runs at 4800 MT/s with CL40 latency at 1.10 V. The 2Rx8 organisation and major OEM chips are stress-tested under load to maintain stability during extended sessions. The kit delivers the rated PC5-38400 throughput without downclocking.

Thermals and power

Operating at 1.10 V keeps power draw low for the total capacity. No heat spreaders are fitted, so airflow across the bare PCBs handles cooling. The design runs quietly in typical desktop chassis with standard case fans.

Questions about this item

How much power does the 1.10V DDR5 kit draw when the system runs all day?

The modules operate at 1.10V, the standard DDR5 voltage, so power draw is determined by the platform's memory controller rather than the kit itself.

What motherboard slot and chipset must I already have for these 288-pin UDIMMs to work?

You need a desktop board with DDR5 288-pin UDIMM slots; the kit is validated for the ASRock Z790 PG Riptide motherboard.

Will the CL40 4800 MT/s modules run stably alongside slower DDR5 sticks I might keep?

All four 48GB modules are matched at 4800 MT/s CL40 2Rx8; mixing different speeds or latencies will force the system to the lowest common settings.
