Finished building and setting up my 4 3900 builds, read my previous post for more details. Figuring out the best way to build them into the shelf was a lot of trial and error, especially with cable management. Took a few hours, but I'm glad it worked out in the end. I was satisfied with my undervolt on the first rig, but unfortunately I was not able to transfer it to the second. I ended up just using dcop and keeping all the cpus stock for uniformity instead of individually overclocking all the machines. Right now they're doing 12.2-12.4kh/s at 80-84c which is making the room quite toasty, should be nice in the winter (not so much in the summer). Would ROI in about 3 years at the current rate. The top machine is a 5600x which I use as a home server, running monerod and p2pool. I used to run nixos but I eventually switched back to alpine like the other 5 machines. Currently using docker-compose and nixery.

Sorry the text is so dense, feel free to ask questions.

Been a Monero miner for a few years now and wanted to scale up a bit for fun. Purchased some used 3900's from ebay, new gold psus, b450 mobos, 2x8 3200 cl16 memory kits, and usbs to boot from. I think I spent about $400 usd per system for 4 systems, total $1600. I could've bought used for the rest of the parts (especially for bdie's instead of cdie) and saved quite a bit, but frankly I was too lazy. I've been working on building the rest of the systems, but the one I have running right now is running 3.5ghz @ 0.95v on the cpu, and 3333 cl 15 @ 1.4v on the memory for 12.5kh/s. I spent a while overclocking subtimings but in the end concluded the time investment wasnt worth the minor gains and decreased uniformity. At current rates, I would ROI in about 5 years. Not too shabby considering I own the systems and can sell them for most of the money back if I ever need.

Currently running Alpine Linux on each of the miners, and I have a separate 5600x server running NixOS that I use to run my nodes (among other applications). I was going to use Nix on the miners as well, but Alpine is easier considering its a single user machine, and probably faster. Of course I'm running my own monerod and p2pool, might throw xmrig proxy in there for stats as well but that can be a future endeavor.

I used to use docker-compose on alpine for my nodes, trying out nix now on my new server. There's a module for monerod but not p2pool or xmrig-proxy yet, not having the greatest time with nix service modules. Might try rootless podman/docker but I wasnt completely satisfied with the container support on docker either.

Curious what you guys are doing :)

Selling my 3950x rig, considering finally building a hobby farm. In the past microcenter had great deals on ryzen 3600/mobo combos and am4 mobos for 3900x's were cheap, but now the bundles are replaced with less efficient 5600x's and am4 mobos are more expensive than the past. Are 3900x rigs still the value king? are the newer budget intel cpus any good? Curious to hear what people think.

I think the sidebar is missing some relevant information, particularly the links and wallets section. I propose it be replaced with something like this.
