I'm embarrassed to mention how much I spent on this machine. Aside from the frequent no-memory failures (S6, STO) on reboot, I'm now getting a 4% on repeated 2D Passmark tests. The workstation is outfitted with two RTX A4500s. The interactivity on the desktop is impossible. Drivers were regularly kept up to date via Dell Command Update. Windows 11. Every possible Dell diagnostic that I could find reported healthy.

Purchased September 2022, commissioned 3 months later in December. 

Glad I didn't decommission my 2017 Precision 7910.

I regret being an early adopter of this AMD configuration. And the hassles I have to look forward to:  OS reinstallation and the joy of dealing with Support. 

If you're serious about your engineering hours, go with the proven XEON configurations.

The 7865 is a beautiful machine and extremely performant when the stars are aligned, but all that's meaningless when remote reboots fail and the UI feels like VNC on a headless Linux server.  I have a $1k Raritan lined up for remote power control -- the reason I asked this question back in March: Dell-Precision-7865-Remote-power-switch-connector
