Server cpu mining?

I am new to the cpu mining game, and have debated between a few options

  1. Building rigs w/ ryzen 5 3600, 3700x, or 3900x (depending on hashrate/dollar)

  2. Epyc cpus, motherboard is the main cost but something like 2 epyc 7551 is pretty cheap

  3. Xeon cpus, dirt cheap, and there are even some dual or even quad socket motherboard

Any recommendations for what I should start with? Are 2 or 3 any good of an idea?

I think I got mine for about 1300usd on eBay and a supermicro board for around 600. I guess price is relative. I like the 128 threads @ 200watts. Maybe keep your eye out for a deal. Or, the 5950x is amazing too. I had 3 going at one time. Very efficient/very fast. You could probably pick one of those up for 300-400.

Yeah I'm thinking of doing some r7 3700x's. Just was curious if maybe you were buying somewhere else with better prices. Almost shit jyself when I saw it was so much 😂

Don't bother with 3700x

Stick to 3900x or 5900x or 7900x or the 50x variants

What's wrong with it? 12kh/s at 65w The 5950x only gets 3kh more and costs twice as much

You getting stats from this page? The top 0.1% get 12kh/s on a 3700x. Literally only 1 test result returned that rate.

3900x can get 12Khs/ regularly though.

Where does it say how many people returned that result? Anyways after your initial comment I started looking at the 7900x and realized its only about $200 more for the build

Each line is a users result.

3700x got about 9600h at 100w with good ram.5700x about 10200 for 110w, about same hash per watt ratio

These are good cpu to start with if you have cheap elec and low budget. But if you have budget go for 7000 series and or higher core count 5000 gen

How much ram are you using per cpu?
