Adamant Custom Ryzen 7 9800X3D Workstation

This Adamant Custom business desktop is a liquid-cooled workstation built around an 8-core AMD Ryzen 7 9800X3D processor. It ships with Windows 11 Pro 64-bit and 128GB of DDR5 memory. The system targets professionals who need high core counts and large memory capacity for compute-intensive tasks.

Professionals needing 128GB DDR5 and 10TB storage

The configuration suits users who rely on 128GB DDR5 memory and a combined 1TB NVMe plus 10TB hard-drive storage pool. Buyers who need ECC memory support or more than four display outputs should evaluate other options. The chassis provides two internal 3.5-inch and two 2.5-inch bays for future expansion.

128GB DDR5 memory capacity decides fit

The single specification that determines suitability is the installed 128GB DDR5 memory, expandable to 192GB maximum. Workloads that exceed this ceiling will require a different platform. The motherboard includes four M.2 connectors and multiple high-speed USB ports for peripheral connectivity.

Questions about this item

Will the 2.5 Gb Ethernet and Wi-Fi 7 connect to my existing 1 Gb switch and older router without extra adapters?

Yes, the 2.5 Gb Ethernet port negotiates down to 1 Gb automatically, and Wi-Fi 7 is backward compatible with earlier Wi-Fi standards, so current network gear works immediately.

How can I verify the 128 GB DDR5 memory and Ryzen 7 9800X3D are running at their rated speeds after first boot?

Open Task Manager’s Performance tab to confirm 128 GB DDR5 is detected, then check CPU frequency shows up to 5.20 GHz under load; the BIOS also reports memory speed and CPU clocks on the main screen.

Does the system ship with four MiniDP-to-DisplayPort cables for the RTX A400, or must I buy them separately?

The RTX A400 provides four MiniDP outputs; cables or adapters are not included, so obtain MiniDP-to-DisplayPort or MiniDP-to-HDMI leads for each monitor you plan to connect.
