buying phenom ii was a mistake i can say......
but it would probably waste more electricity than mine

Hello, just a dumb question here, but please help to answer !!

What is the most profitable coin to mining by CPU right now? thank

There are many threads dedicated to this topic. I place zero credibility in these discussions. There are 3 types
of advice: from those who don't know what their talking about, from those with ulterior motives, and occasionally some
sound advice. 

It's better to learn than to rely on the advice of others.

However, in general terms coins that can't be mined or can't be mined efficiently with a GPU or ASIC are more CPU friendly.
Your assignment, should you choose to accept it, is to find those coins.

Hi Dev, thank for the response. I'm well-known that 1 CPU can't compare to many GPU. But I have 1 corei7 Skylake sitting freely on the board, i'm looking for the coin which friendly to CPU to try out now. Do you have any proposal?

[joblo]

Let me be more blunt. Do your own research, I don't make recommendations.

I7 4700k can earn something? Or electricity is more than profit?

I was able to mine AEON, BitSend, and Monero on my i7 6700K.... there were others I tried out, but I'd try mining one of those three to start with on your CPU. You won't get rich, but you should be able to at least pay the electricity costs.

Any plans to support BiblePay?  Proof of Biblehash (PoBh).  Very unique algorithm and a coin with a noble goal I think (big charity focus).  https://bitcointalk.org/index.php?topic=2042657

No, it's not POW.

Gotcha, thanks for the quick response (I wouldn't know the technicality of what makes something work-able or not, just seemed like a decent project for those who aren't put off by the religious undertone).

Anyone planning on testing Threadripper?

Anyone planning on testing Threadripper?

I was seriously thinking of buying one, but wound up setting the funds aside for repairing our septic system instead.  It will most likely be the equivalent of 2 Ryzen 7 1800 CPUs for hashrate since it's essentially 2 R7 CPUs combined together... so a beastly good miner as far as CPUs go.

A heads up for those mining on yiimp with a CPU, you may see rejected shares for low difficulty.

Thank you joblo for this great tool.  I just started my test run with it.  Can't wait to see the results.  Thanks.

Hi there. Joblo, thanx for your great work. Can u please check the possible issue? The problem is hashrate reporting while solo mining (getwork):

         **********  cpuminer-opt 3.6.8  ***********

[2017-08-14 09:29:31] Binding process to cpu mask f
[2017-08-14 09:29:31] Binding thread 0 to cpu mask f
[2017-08-14 09:29:31] Binding thread 1 to cpu mask f
[2017-08-14 09:29:31] Binding thread 2 to cpu mask f
[2017-08-14 09:29:31] Binding thread 3 to cpu mask f
[2017-08-14 09:29:31] 4 miner threads started, using 'cryptonight' algorithm
[2017-08-14 09:29:32] Current block is 19325
[2017-08-14 09:29:32] No payout address provided, switching to getwork

Then it may take about 10+ minutes to display hashrate, or even up to 1 hour (the result will be printed for all that time though). Tried several coins and several algos, as well as sse42 and avx/avx2 versions, and the previous 3.6.7 version. No changes there. I personally do not see some walls to avoid hasrate output, as all built-in-wallet miners do that. This reproduces both on win7 and win10.

It's hard to tune settings (I'm not about cryptonote algo, of course) for new coins with such a wait I had to use shitpool with zero miners and broken payouts to tune Cos on stratum work there's no issues.

I use some kinda stock .conf file, which is similar for all the coins.

Maybe there're some solutions rather than miner's code? Thanks.

No, its not what i meant.. its just the minimal static diff is now limited

My misunderstanding. The impact will be infrequent share submissions.
