curious question ? why are you guys mining with NVidia and AMD video cards ? do you have asic miners like Avalon , Bitmain , Spondoolies just to name a few. even though video cards are asic's but real slow for mining. or your just having fun ?
GPUs are non ASICs. Some algos can only be mined with GPUs and can at times, and depending on your electricity cost, be profitable (quark, x11, neoscypt and lyra2v2 for example). |

a little speedup by better compiling:
Intel(R) Core(TM) i5 CPU 760 @ 2.80GHz
AES_NI: No.
SSE2: No, start mining without optimizations...

[2016-01-26 13:39:37] accepted: 7/7 (100.00%), 224.92 kH/s yes!
about 5-10% more by using this commandline (to be adapted to your own cpu):
./configure CFLAGS="-march=nehalem -Ofast -DNO_AES_NI" CXXFLAGS=$CFLAGS --with-crypto --with-curl
and remember to "make clean"

It's all a matter of if you care for the coin.
If you care, run a wallet and solo mine, that way you secure and support the coin network the best way.

Why Vertcoin (VTC)
4. LYRA2RE has a ~15% power usage reduction on X11
I wanna see this test done again. Why? things have changed since lyra2rev2 booted. both nvidia and amd have faster miners which, of course, draw more power. |

It doesn't support AES, it's a Nehalem.
I think the miner should be compiled with the best "-march" as it will impact the performance of most kernels, regardless how far your optimisations will go.
On a side note, I've found out that -march=native may lead to slower binaries than -march=<the best for your cpu>
AFAIK corei7-avx is tops do you know of anything better? The best is your right chipset name: https://gcc.gnu.org/onlinedocs/gcc-4.9.2/gcc/i386-and-x86-64-Options.html |

Is it correct that "SSE2: No"?
AFAICS, it runs fast anyway.
Checking CPU capatibility...

Nope, it's a bug. I think it will be irelevant when I implement X86_64 compiling. But "-march=x86_64" won't configure. I don't know if it's the wrong target name or if GCC has dumped support for it. Maybe I need to install some compat packages. Edit: just checking your output again. even though it says no for SSE2 it should still the SSE2 kernel. Formyour hashrate it appears to be normal for and i5 SSE2. I guess the early corei didn't have AES_NI. Do you want to give it try to make sure? Just edit cpu-miner.c:1949 and hardcode cpu_aesni=true. Then compile with AES_NI enabled and let me know if it works. Thanks It doesn't support AES, it's a Nehalem. I think the miner should be compiled with the best "-march" as it will impact the performance of most kernels, regardless how far your optimisations will go.

In all honesty, I can't recommend this service as an investment.
In about 6 months time, my profit is -4.7% (negative!).
A lot of people just don't pay their loans and there is no way to get the money back (unless you live in the loaner's coutry, possibly).
It looks like they pay until they get to rating A, then run away with the money.
I can't even read the comments, because they are insulting: "I can't pay back, I need to first sell my plane".
It'd be funny if it wasn't my money.

Cool. I didn't mean slack was obsolete, just that people who like it are old school. I've played with it but never any real work. At one time I had 8 different distros multibooted on 2 20GB HDDs running on a pentium 1. Now the're all in VMs. A guy I used to work with was a slackware fan. Give him the keyboard, toss the mouse, and he could do magic. He's was also pretty sharp in networking, knew his protocols inside out. I started using Linux with Slackware 2.0 :-) |

i hope WOLF0 will make a good pablic algo for decred coin when the mining will start.....
ps: wolf0 u must know that u r my favorite...U prove yr work with facts & not with many sauces.....THANKS FOR ALL!
I hope Wolf0 will prove me wrong, but I fear there is not a lot to optimise on blake 14 rounds. I might be able to prove you half wrong. Got a 6970? No, smallest card I have is a 280x Too bad, I could probably make that thing do wonders on Blake. I've got an idea! Maybe a 5750 (juniper) will do? :-) |

I hold some TTYs and wonna understand what's the long-term plan.
Depending on that I'll choose if to keep, to mine, whatever.
Thanks.

It's very unlikely that the code has no opensource parts, unless he rewrote everything.
And he's talking about "optimisation", not a new software.
Now, the license is often broken: there are a lot of miners, private and public, in this state. That's because nobody will likely sue.
BUT
It's not a reason to think it's ok.
Opensource licenses made cryptocurrencies possible, and a lot of other things we use every day: smartphones, routers, servers, televisions... all those use linux and/or other opensource software; even apple and microsoft products very often include opensource parts! And they respect the licenses.
So please respect opensource and the GPL, and preserve its value.
Don't be an opensource parasite.

Please add a link to the old thread: it can be a useful source of information.
I'd highlight the sections a bit more for a better readability.
Thanks.

I APOLOGIZE FOR FALLING ASLEEP--
But I did wake up and found 2 and 1/2 pages of posts that threaten to put me back to sleep.
My miners toiled away like zombies while I was in bed In a few days, if the beer holds out, I'll be able to donate again... or maybe buy beer instead. --scryptr
you just need more popcorn  (I am grateful to myself to have used the moderation feature on my thread ) you deleted one of my posts, now I'm gonna troll you forever!!!! just joking ;-D |

I can confirm that old intel cpus (>= core2) can have performance/power similar to much newer amd processors.
So don't buy amd cpus for mining... well... do not buy any cpu for mining ;-)
