Workstation for Compute-Intensive Tasks

This business desktop pairs an 8-core AMD Ryzen 7 9800X3D processor with 128 GB DDR5 memory and a 240 mm liquid cooler. An Nvidia RTX A400 GPU provides four Mini DisplayPort outputs for multi-monitor workflows. The system ships with Windows 11 Pro 64-bit and includes Wi-Fi 7 plus 2.5G Ethernet connectivity.

Suited for Local Simulation and Multi-Display Work

Professionals running memory-heavy simulations, large dataset analysis or GPU-accelerated applications will use the 128 GB capacity and professional driver stack. Buyers who need more than 4 GB of video memory or certified ISV support for specialised CAD suites should evaluate other configurations.

Deciding Specification: 128 GB DDR5 Memory Capacity

The installed 128 GB DDR5 kit determines whether the workstation can hold entire datasets in RAM without paging. The motherboard supports up to 192 GB, so the current ceiling is fixed by the fitted modules. Verify your application memory footprint against this figure before purchase.

Questions about this item

Will the PRIME X870-P motherboard accept my existing DDR5 modules to expand beyond the installed 128GB?

The board supports up to 192 GB of DDR5, so you can add compatible modules to the four slots alongside the factory memory.

Can I keep using my older SATA SSDs or hard drives with this system?

Yes, the motherboard provides two SATA 6Gb/s ports and the case includes two internal 3.5"/2.5" bays for legacy drives.

How can I confirm the liquid cooler is running correctly after I power on the workstation?

Check that the 240mm AIO pump RPM appears in BIOS or monitoring software and that CPU temperatures stay low under load.
