12-Core Ryzen 9 Workstation

This Adamant Custom desktop pairs a 12-core AMD Ryzen 9 9900X3D processor with 128GB of DDR5 memory and a GeForce RTX 5080 graphics card. A 4TB Samsung 990 PRO NVMe drive provides primary storage. The system ships with Windows 11 Pro installed in a CoolerMaster HAF 500 mid-tower case.

Suits modelling and AI workloads

The 128GB memory capacity and 24-thread CPU serve modelling, video editing, rendering and AI learning tasks that demand large datasets in RAM. Builders who need more storage than a single 4TB drive or who require multiple graphics cards should look at a different platform.

128GB DDR5 maximum capacity

The motherboard supports up to 192GB across four slots, so the installed 128GB kit leaves room for future expansion if workloads grow. If your current projects already need the full 192GB limit, this configuration will not meet that requirement.

Questions about this item

How do I confirm the Ryzen 9 9900X3D is running at its 4.4 GHz base clock after setup?

Open Task Manager or a hardware monitor and verify the CPU shows 12 cores, 24 threads and a base frequency of 4.4 GHz with boost up to 5.50 GHz.

What components are included and what must I add to start working?

The system ships complete with the Cooler Master HAF 500 case, 240 mm liquid cooler, X870 motherboard, 128 GB DDR5, 4 TB Samsung 990 PRO SSD, RTX 5080 16 GB GPU, 1000 W Gold PSU and Windows 11 Pro; only a display, keyboard and mouse are needed.

Which memory capacity should I choose if I want headroom beyond the 128 GB installed?

The X870 board supports up to 192 GB across four slots, so you can add another 64 GB kit later if workloads demand it.
