I have 2 tickets outstanding on the old stake pool. It used to have instructions on importing the key to your wallet. I cannot access it. All I can find is my publickey. I try the importpubkey command and keep getting an error. I'm afraid to upgrade and loose access to my coins. I have tried google, and cannot find instructions. Do I need to import some kind of private key, which I didn't record?

Do you still have access to you old wallet's log file? There's a small chance the key is in there and I can guide you on what to find. Just PM me.

We strongly recommend all users to update to latest NiceHash Miner version 1.6.0.0.

Version 1.6.0.0 brings:

  • Increased performance on NVIDIA mining by automatically setting optimized power state.
  • Up to 20% faster Decred on NVIDIA GPUs.
  • On-GPU DAG generation for DaggerHashimoto for much faster benchmarking and no more HDD needed.
  • Added tooltips for relevant config settings.
  • Numerous bugfixes and small improvements.

Download the full package, unzip & run.

Keep on mining! Wink

Best regards,
NiceHash team
What does it mean:

Increased performance on NVIDIA mining by automatically setting optimized power state
This gives more hash rate?
In the folder I see file nvidiasetp0state.exe
Should I run it manually?
I run the miner without GUI through the bat file from the bin folder.

On some algo it does give some extra performance. All you need is to enable it in the settings (set NVIDIAP0State to true by checking the checkbox). Your millage may vary so just benchmark once before enabling it and once more after enabling it and see if you like the speed difference.

 Wish I could, but your insistance on using broken github makes it impossible for me.

 Still waiting on a reply to my earlier question of "where can I get it that does NOT use github".


Here ya go a Google Drive link: https://drive.google.com/open?id=0B6kB9L8GNvQwMlIxZU9LTjNzbGs

This is a beta build so if anything weird happens, please do report back.

Thanks.

Hello all,
Tried all versions of sgminer on different pools and always get this error:

Latest AMD driver have an error in OpenCL compiler and can't find files to include. Easiest solution just to revert drivers, i use 15.11, works best for me.

BTW, for eveyrone who is saying: best algo, low temps. Are you all drunk? It is low temp just because miner written in a shitty way.

Another fix would be to copy all the kernel files (.cl) to C:\Users\KOLJOM~1\AppData\Local\Temp folder.. should fix it too..

Hello guys,

I really don't want to bother anyone with newbie question, but does anyone have working rig with 6*750ti, nicehach miner and ethereum? I am struggling for a long time with configuration, ant would appreciate any help. For now, I am only asking if anyone got it working, and if anyone want to help me to get it working.

I must say that every other algo is working like a charm except ether.

Thanks...

You will have to change some setting.. try to follow this user's guide and see if that helps (https://github.com/nicehash/NiceHashMiner/issues/87#issuecomment-212713258).. you might need to play around with the numbers..

Hmm, unfortunately there seems to be a small but annoying bug - if you start with clean NHM (without config) then the entered Bitcoin address is not stored in config.json and therefore not used in the benchmark. We'll release a bugfix soon, meanwhile just "Start" miner for a few moments (will start mining on first algo - X11), then Stop miner, close NHM. Then start NHM again and you should be able to run benchmark.

Did that. Ethereum is still not running in the benchmark.. I'll download it again.

yes mine seems to be stuck on ethereum as well..

wonder if its timing out because its taking too long to download the dag..
Do you have to close yours with the Task Manager ?
it says please wait.. been like that for over 10 minutes..
i pushed stop and it doesnt stop.. seems stuck.

the system is idle..


ok edit.


the app isnt writing to the directory.. its the problem with the bitcoin address.. i just restarted and now all the benchmarks are zero.

going to try it as admin.


edit 2, didnt work.

i just manually set the eth benchmark and now it seems to be working.

so once the dag was made you can benchmark..
so the work around would be to put a high number manually in, like 50000000 then hit start, let it make the dag and stop and it run the benchmark.


To @Stein & @aarons6 :
Ethereum takes a while to create the DAG file. It may take around 10 minutes on a relatively new CPU to create it. Then the benchmark would start and you should see some GPU usage. Regarding the Bitcoin address, it will be fixed soon. Thanks for the feedback  Wink

Re: [ANN]: cpuminer-opt, the optimized multi-algo CPU miner
by
theLosers106
on 12/04/2016, 12:28:17 UTC
cpuminer-opt v3.1.13 just released. Added support for a few dusty algos:
sha256d, scrypt, scryptjane and yescrypt.

If anyone  knows of anywhere to pool test any of the remaining algos please let me know.
I'll even test you your address.


You can test scryptjane at YACoin pool:

Miner config:
Code:
-o stratum+tcp://yacoin.club:3433 -O alenevaa.CPU1:1

You can use 2 ports:
- 3433 difficulty 1
- 3434 difficulty 0.25

If you miner doesn't support difficulty less than 1 - use port 3433

Thanks but scryptjane has been pool tested. When I said remaining algos I was referring to the ones that have
not yet been tested in a live pool. Specifically they are X17, blakecoin, fresh, cryptolight, and bastion. I have not been
able to find any pools offering to mine coins using these algos.

Sorry for the confusion.

For blakecoin you could use this pool: http://ny2.blakecoin.com/index.php?page=login

Got a weird problem trying to use nicehash miner.  I have one machine on which it refuses to run (The one I actually want to use it on) Its a pretty high spec machine and I cant think of anything that would be causing the failure. 
I just get a "NicehashMiner has stopped working" message. Doesnt get to the interface or anything.  anyone had anything similar to this? 
Exception from the CLR, very odd.

What OS, CPU and GPU are you using?

Very interesting project, unfortunate that Nvidia miners are not getting the same love as AMD

Do we need to crowd fund to get something valid released?


Maybe we just do not have enough Nvidia miners to Justify our existence.

Really, you're not being as picked on as it seems - CUDA is great when it comes to more complex algos, or algos that can benefit from Nvidia-specific optimizations that the compiler is unable to find by itself, but this is not the case for Decred. Really, you're talking about a minor bump I would guess, at most. The algo is dead simple - I've made the miner a few percent faster on AMD - but we're talking single digit percentages... and low digits. The Nvidia OpenCL compiler would really have a hard time fucking it up.

@wolf I tried the cgminer & ccminer both & they give me

970 1.52 GH/s on ccminer & 1.11GH/s on cgminer
750ti 530MH/s in ccminer & 431 MH/s on cgminer

so there is 75-80% loss in hashrate. Also as i remember, ccminer was running at much lower TDP% as shown in Afterburner, ~80% while cgminer was using 98-100% power. Considering all this i think there is a big disadvantage & some potential for optimizing ccminer for decred, unless the modification required for decred somehow lower the hashrate. But i guess ccminer devs are too busy taking potshots at each other, so we will have to make do with what we have or wait for decred team to release something.

Dude, of COURSE there is. That's 8 round Blake, this is 14 round Blake. Try to understand what the PoW is before benchmarking.

Since 14 is 75% more than 8... you're DEAD ON.

Nope that is for 14 round blake. On 8 round blake i get 2.5GH/s & 920 MH/s. I am mining VNL right now. I am a noob but not that much.

*facepaw* VNL is 8 round.
@wolf exactly 8 round blake on VNL is giving me 2.5 GH/s & 920 MH/s and 14 round gives me 1.5GH/s & 520MH/s on ccminer. What is facepalm about it? still cgminer is 80% less than what i get on ccminer for 14 round blake. Also 14 round blake is 60% of 8 round blake on ccminer so there is some room for improvement if as you say it should be 80% of 8 round blake. Dude you totally taking me for a moron or am i really missing something here?

I don't get it - how are you testing an 8 round Blake-256 on ccminer when it's not implemented?

Its implemented for VNL for sure & i guess for blakecoin as well, although i am not sure, in tpruvot's ccminer fork. I am using that.

See, when you say things like that, it makes me think you misunderstand. You see, VNL uses eight round Blake-256. Blakecoin uses 8 round Blake-256. Decred is the only one I know of using 14-round Blake-256, and it doesn't have a CCMiner implementation yet as far as I know, so I'm unsure as to how you've benchmarked it.

Not to pissed anyone.. but Wolf0, I'm assuming he is using this: https://github.com/tpruvot/ccminer/blob/windows/ccminer.cpp#L1833 to benchmark..

Progress update

I've worked through some of the windows compile errors I was getting frustrated sochanged gears
and started working on sse2 support.

sse2 qubit works and will be included in the first release.

I can get sse2 working on one algo that uses groestl at a time. If I include the sse2 groestl files in two algo
at the same time I get multiple definition linker errors. The included files are full of macros so that kind of
explains it. I may try turning them into functions so the files that include them don't pull the coded into
themselves. If that works it will probably have a performance impact, hopefully not too big. I

This affects all the x algos and quark.

Here are some updated hash rates from my i7-4790K 4 GHZ showing the sse2 performance.
This shows the difference between the aes_ni optimized kernels and sse2 on the same cpu.
Actually running it on an older cpu will probably have even lower performance.
I can't test sse2 on a real sse2 limited cpu because my core2 pc runs windows.

                   aes_ni   sse2     sse2/aes_ni
x11              707k      529      .75
x13              320        
x14
x15              280
quark         1080      907        .84
qubit          1045      755        .72
 

I spent the last few hours working on getting this compiled. I'm using a VM within windows 7.
I tried 4 different flavors of Linux and either it doesn't like Linux Mint 32/64 bit or Ubuntu 64 or
I'm missing some dependents it needs to compile correctly & never makes the cpumimer executable.
What OS and version are you using? I'll give it another go once I get that info from you.
My Linux skills are pretty rusty "never was all that great  to stat with" but I'm fairly sure I was doing everything correctly.

Hey,

I used Fedora release 20 64bit with GCC v4.8.3 to compile and it worked fine. The release version and the GCC version is outdate
but hey it works. (:

If you guys can improve x11 or Ethereum that'd be worth some coin. Please consider targeting the big algos.


Hm. As you wish.

It's not nice to play with a young boys heart. Cry

Spread is also a good one worth targeting right now.

Spread? I hadn't thought about that, but I probably could do something with that...

gigabyte 980ti extreme is sitting on the nvidia test machine now wolf ...

wanna play? ... its all yours Wink ...

remember to stop it mining first before any testing on it please ...

thats IS you are interested in dabbling with nvidia again mate ...

im off - back tomorrow ...

#crysx

I was thinking AMD, though.

the amd test system is still there and running with the gb280xoc ...

will put another card on it tomorrow - gb7970oc ( pretty much the same thing as the 280x oc ) ...

the amd machines continue to fall over wolf - im getting near my wits end with it ... even the ones that have come back from warranty repair have some units still dying - this time NOT from the fans ... the actual card dies ... which takes out the entire miner and all the cards contained in it ...

this in turn makes it look like im not keeping my word with what i had promised to have in regards to the farmamd ...

ill try and fix it tomorrow - as im home now and need some personal things sorted tonight ...

i think the nvidia machines will be a closed system soon ( like ive done with you and the amd side ) except the nvidia will be granite based only - for granite use ... so i can grow it to the size that i want it by the end of the year - 7gh on x11 ...

had it not been for the fact that these amd cards continue to crash - they would be a solid stable system ... as it stands - they fall over way more than im willing to give time to mate ... i think with these cards - i need to find a cool room somewhere and run them in there ... lock them away with only cold air running on them ... that would stabilize them a little i think ...

the nvidia cards heat - but they dont lock up and fall over ... they just throttle ...

what would you suggest i do with the 25 of these cards? ... only 16 are running currently - and they are the ones falling over all the time ...

maybe its the drivers and the system ... i dunno ... all i know is they have taken more of my time away from all the other things in my life - than the nvidia cards ever have ...

ill sort my person stuff out tonight - and deal with that tomorrow ... suggestions would be great at this point ... as i dont want to throw them out - and certainly cannot keep servicing these things ...

#crysx

I'll look into the crashing - give me some time.

Does't sgminer have temperature limit setting? Does it not work on Linux machines?
If that does not work, maybe you need some script or miner controller software that will stop mining
if gets too hot. Less efficient but better for you as hopefully less card goes dead..

My other suggestion would be to put fans in between the cards to try cool it down better.

Hi joblo,

Currently testing the cpuminer on an Intel(R) Xeon(R) CPU E3-1230 V2 @ 3.30GHz ..
Running using Fedora release 20 64bit .. a bit outdated as I'm too lazy to upgrade it as there are a lot of things running on it..
So far it is doing quite well but I keep getting "Result does not validate on CPU!" ..

EDIT2: Tested with x11, X13, X15, Quark and Qubit algos.

Will keep you updated as each test takes a while to get any accepted..

While waiting until I downgrade to VS 2013 let me indulge myself as I ramble on about who I am.

I'm a 58 year old computer geek who was laid off with a good severence package 8 years ago less than
a year before the company went bankrupt.

The proprietary system I worked on used Motorola 68k, 88k and powerpc cpus. I was most familiar with
the unpopular 88k. My claim to fame was discovering a bug in the branch prediction which ironically
improved performance once it was disabled. Apparently the BP conflicted with a compiler optimization
even if it had been working properly. The 88k, Moto's first venture into RISC, however, was short lived.

The software system was an integrated development system consisting of a run time real time operating system,
it's applications, a Linux based (originally IBM mainframe) multi-site program and documentation library,
and compiler all written in and for a proprietary high level language with similarities (ie strict type checking) with Pascal.
I really learned to love the language and it has some great features, with OO added later. One of my favorite quirks
in the language was the guzinta: "->". This is unlike similar c++ operator. It is the assigment operator
and works like this:  "value -> variable;".  Some of your may recognize it.

it had some important features like not defining the null pointer as 0. nul always pointed off to invalid address high
up in the address space. Address 0 was also invalid and would throw an exception if accessed. The languange
also had array index protection built into the compiler. An index out of range also would throw an exception.
There was also a built in data structure (nice to own your own compiler) called a descriptor that was essentially
a pointer to an array. It also had index protection. c++ probably has a class similar to the descriptor but without
index protection. That feature alone made the system so much more resilient to memory corruption and easier
to debug, but most importantly the concept of a buffer overflow did not exist. The compiler would not allow it.
Imagine how many fewer exploits there would have been had c/c++ had such protection (at a slight performance
cost).

I've never done any Linux or c++ development although I had some exposure to c++ at work. Many of the concepts
are so different that what I am familiar with and that slows me down a lot. I've used HP-UX, solaris and linux as
desktop workstations at work and used linux at home since Redhat 5.2.

Although I'm comfortable with assembly code I haven't touched Intel since the 8000 series. That will make the assembly
language files tough to work with. I have a couple of optimization thechniques I've used in the past but they require
intimate knowledge of the Intel architecture such as memory interface, cache organization, execution environment,
instruction issue and retirement throughput, and things I'm probably not aware exist. I have a lot to learn, but that's why
I'm here.

I know nothing about cryptographic algorithms so don't expect me to code new algos. I'll leave that up to others.

I had heard of Bitcoin but didn't get involved until very late (too late) in the darkcoin frenzy in April 2014. I started
with just one CPU but unknown to me at the time ASICS had taken over bitcoin and scrypt was next. And GPUs were taking
over the altcoin algos. I bought a gt730, a nice little card that performed on par with my i7-4790K. I bought a 750ti shortly
after that and a few other cards since then.

Well that's how I got here. I'm bored with lots of time on my hands so I've been poking around at miner code here and there.
I'm even less familiar so I took a shot with a cpuminer and was surprised. It is a credit to Pooler's design that I was able to
pull together code from 3 different miners and make it work smoothly and efficiently in a short time.

VS is still installing but I think it's time for a break.

I must be getting tired I just tried to post this to the wrong thread. I giess i don't have the stamina I did 25 years ago.

Thanks for reading and taking an interest in my project.

I'm having some difficulty compiling on Windows with VS community 2015.

If there is anyone who can help it will speed up Windows support.

I editted  cpuminer.vcxprog with a text editor, not VS's built in editor.
I modelled the changes based on the sources list in Makefile.am,
but I really have no idea what I'm doing.

I added a bunch of entries to this list:

Code:
     Full
    
    
    
    
    
    
    
    
    
    
    
    
    
    
    
    
                   <------- error here
    
    
    

I get the following error.: The attribute "Include" in element   is unrecognized. I've shuffled
the order of the list and it errors on a different file everytime but the same line number.

Any ideas welcome.
    

Just wondering if the folder's name sse2x6 correct?

Easily the niftiest little auto-miner i've seen yet.  Downloaded it, fired it up, worked immediately.  (R9 290 + Latest Omegas)

Also going to use it to test out 4-5 card rigs.

Great job Nicehash, i hope you make some $$$ on this one.  You're saving some serious headache.


Edit - Would like to see an "ez donate" button like you see with the PayPal button. This is the kind of software that i donate some coin on due to its usability.

Edit2 - Would also like to the rate in mhs BTC/day or ghs BTC /day as opposed to just BTC/day.  I can assume that it's GHs/BTC/day, but can't be 100% certain.

Edit3 - Would also be quite awesome if there was a way to upload benchmark numbers to some sort of global online number set so you could look and see where you stand (and if your config needs tweaking!)

You've got some interesting Edits right there. Especially the last one.

I'm about to fork this bad boy and see just how extensible the code is.  

Edit #3 is certainly something that would be useful for me personally, but also for just about anyone else out there who is mining and who wants to ensure nominal hash rates. If done correctly, this type of reporting could minimize the effort required to maintain a 'hardware compendium' of sorts (think back to the original LTC Hardware Mining Compendium page).  Great help to miners, but PITA to use and maintain.

Then again, this is definitely a 'nice to have.'

The reporting "module" if you will is certainly out of scope with the pure function of this app, which is to mine.  It does this primary function well, and is the reason why i even bothered to post in this thread about it.  The app's mining capability must be maintained at all costs.

However:
I do wonder how easy(? - may be difficult!) it would be to simply grab those scores after the benchmark(s) are run and cart them off to some online spreadsheet along with the configuration existing at the time.  The 'compendium' page would be view only, and writeable only by the reporting mechanisms used by the mining app.

To the whiteboard!  Grin

Sounds great!

If you want, i'm definitely willing to help with that.

I could do the webpage "spreadsheet" / database part.

Just pm me if you could use some assistance. No problem!

That's sounds great.. had this idea for ages now but I just haven't had the time and someone to do it with.. would be nice if we could all work together to make this happen.. have a few thoughts on this idea already stocked up.. (:

ccminer -a blakecoin --url=http://127.0.0.1:21 --userpass=myuser:mypass
I get this cryptic error:
Code:
[2015-12-31 17:52:14] NVAPI GPU monitoring enabled.
[2015-12-31 17:52:14] 1 miner thread started, using 'blakecoin' algorithm.
[2015-12-31 17:52:14] Binding thread 0 to cpu 0 (mask 1)
Cuda error in func 'blake256_cpu_setBlock_16' at line 703 : invalid device symbol.
My device is GTX670M in a gaming laptop with optimus.
Can you help, please?

Your card is using Fermi based GPU so you would have to use this ccminer instead. Happened to me once  Tongue
