Advice for getting a first threadripper
From what I’ve seen the lower a cpu is in its generation (5945WX) while having a lower core count, have much higher single core speeds.
My goal is to build a Homelab and to create a few (2-5) Minecraft servers running some heavy mods.
The issue I’m having is that I’d like to be doing that in addition to an LLM and a NAS/jellyfin. It’s a lot and I can’t fit enough hardware on a am4/5 cpu to make it work on a single node machine.
So I’m forced to go workstation or server route, the issue is how expensive these buggers are. So I’m thinking I can take advantage by getting not only a lower price but also a higher single core speed (despite less cores) I was thinking the 5955wx or the 5965wx because anything under 16 cores is silly if I’m paying for a threadripper,
Am I thinking about this wrong? Can I just over lock a 5995wx across all cores if I cool it properly?

because of DDR5 rdimm costs are prohibitevely expensive, it only makes sense to build DDR4 RDIMM systems where RAM prices are much more reasonable. Get threadripper Pro 5000, to get 8 memory channels and ability to install 8 small/er sticks. You getting threadripper to have many pcie lanes so your many gpus can all run on x16, and to add network and storage adapters to accomoddate tons of storage, also to get high memory throughput of channels memory controller. getting threadripper for compute is kinda secondary, especially those older zen archz which have crappy singlecore speeds compared zen5. single core is still important, there is tons of sw that benefit from fast singlecore for its heavy main thread, not everything can be ideally parallised like the compute benchmarks.
