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.
Might post pictures when its all done if anyone is interested, bought a cute little 5 tier shelf for the 5 machines since they’re sitting in my room right now.
You do really good here, because you add diverse Operation Systems to the Network. Well done,.that’s not valued enough all around the space!
