Not me anymore ![Cool](https://bitcointalk.org/Smileys/default/cool.gif) Right .. so its probably the power bill that stops it from being profitable, coz 1 good GPU is $600 + and the server I want is 128 cores for the same price. The hardware costs are about the same. Am I still seeing this wrong?

Well some people have access to idled extra rows of cabinets old servers in a noc, free power and hardware equals time to get creative with mining low diff alt coins. ![Grin](https://bitcointalk.org/Smileys/default/grin.gif) This is pretty much the only case for CPU mining. Finding some random altcoin that everybody has lost interest in and consequently the difficulty has dropped. Of course at that point the coin is to be considered dead and won't even be listed on an exchange. Those are dead coins, zombiecoins. Examples would be Kittehcoin and Lottocoin which are now worth less than a Satoshi each. You could CPU mine those dead things and hope for a revival if the dev puts time into it - basically gambling. But if you have that much free time, I would make my own scam coin, premine 80% of it like BCN, and then promote the hell out the scam. Is it immoral - yes. Is it what almost all the scammy altcoins are doing - yes.

So just curious anybody out there still CPU mining protoshares. Is it still profitable?

While protoshares may individually worth a lot they are damn near impossible to mine unless you have a botnet or some 500 machine farm. I used my wife's office computers for a month (i5s) and I think 8 of them made less than $4 - about a penny a day per CPU. A botnet owner could make money with it, but most botnets could find a more lucrative source of income like hired DDoS - botnets and DDoS are both illegal activities BTW.

Add me to this list ![Grin](https://bitcointalk.org/Smileys/default/grin.gif) Solo mining in the hope that i hit a block and then i will be rich!! ![Cheesy](https://bitcointalk.org/Smileys/default/cheesy.gif) Seriously though, power is fairly cheap where i am, so i hardly lose anything!

Good question! ![Smiley](https://bitcointalk.org/Smileys/default/smiley.gif) Currently I'm mining XPM on CPU. But it's interesting if anybody have better coin to mine on CPU (based on experience not theory ;-) btw: good CPU coins site: cpucoinlist.com

I've been mining Monero on my CPUs for a little over a month (right about the time difficulty jumped up) and my CPUs are still turning a profit.

I switch off between Monero and Dimecoin when I have some free cpu time. Im not expecting to make much from dimecoin, but I have hopes that Monero might go up in price someday. Either way its only when the computer has to be on and has free cpu time.

Started playing around with CPU mining again (nostalgia from 2012) and was looking at cryptonote coins (Bytecoin, Monero). Using a 12 core Xeon, I get about 135 hashes a second. Some miner on minergate.com is getting 10 kh/s, which translates to 0.05btc a day.
Other than a botnet personal army, anyone have any strategies on CPU based mining to maximize profits?

What miner are you using? I get 265 H/s from an i7 3770 using Wolf's miner with threads=1/2 of cores (physical or virtual if it has HT). Having AES-NI is a plus as well as running on Linux instead of Windows. But that's just what gets me the best results. Xeons seem to be different to tweak than desktop CPUs. And no, you're fairly limited unless you have a lot of CPUs to work with. Here's a somewhat useful chart: https://docs.google.com/spreadsheets/d/1MI-ic0Os25hgGUImW54sUIjZY_pUNQNa_W8Se5pRGBs/edit?pli=1#gid=0

Thanks for the spreadsheet link! I also just saw someone has a GPU miner now too (Claymore)... It doesn't seem like thee CPU-only algorithms last very long.

Held #1 for quite a while. Strato

4x E5-4650 server gives 1534H/s with wolf's miner.
Interesting thing: if run by default (64 threads), I had about 1050H/s. Running at 32 threads (4x E5-4650 is 32 threads) I get 1534H/s. So, beware of HT CPU's, and running too many threads!

This has been documented on nearly all CPUs. I actually get better results running 3 cores on a 4770k vs 4 or even 8. HT kills returns - and it's best to leave room for overhead. So if you have 6 logical cores - 12 in HT; best to try 5. Strato
