I'm a researcher at a major university and I've encountered significant slowdowns with my workflows on HPCs. A few years ago, I decided to build my own Threadripper setup, which has served me well, but I'm now dealing with much larger datasets that can reach several TB and require better performance. Currently, I have a Threadripper 3960X with 192GB of RAM and a GeForce 3090 GPU. However, I'm often limited by memory and not utilizing my GPU effectively due to the skill levels of my research assistants who are less experienced with HPCs.
I'm looking to build a new rig optimized for CPU-based workflows with around 8-10GB of RAM per worker and significant NVMe expansion capability, targeting at least 384GB of RAM. I'm planning to use it for everyday tasks, including light gaming. I want to stick with DDR4 for cost reasons and I'm primarily buying used components. Additionally, my budget will be whatever I can sell my existing rig for plus 1-2k. I can't keep my Threadripper because I'm unable to find a board that supports the RAM amount I need. Any suggestions for CPU, motherboard, or overall build?

For your needs, I'd recommend looking into dual-socket Xeon or EPYC systems. These setups often come at lower prices now that many servers are being decommissioned. You can find high-core-count CPUs and plenty of RAM options at reasonable prices. Just be aware that you'd likely need a proprietary motherboard, and cases might be more limited, but there are decent options like ASRock Rack that can work well for you.
Thanks, I’m definitely considering EPYC as an option. I’ll keep an eye out for good mobo-CPU-RAM deals on eBay. Appreciate the tip!
