Have anybody Linux config file for exapmle? I've tried to run dashminer on BAMT 1.3 32-bit but error "Segmentation fault" has occured.
P.S. Latest sgminer works fine. AMD 14.6 drivers.

I did try it on BAMT, works fine.

What is your config? I might have a look.

I took config from sgminer that I use. I didn't find any config for dashminer. Can I have the sample?

I have a bit of a problem.  Hopefully we can get this issue sorted out.

So here is the deal.  I run sgminer 4.2.2.  Just open source stuff that I have found via forum crawling.  I have a single r9 290.  I read that dashminer uses x11 as one of its algorithms.  The reference given was found here http://dashminer.com/stats/.  As it states, the reference r9 290 card crunched out 4.84Mh/s, and they are using this as a sort of baseline reference for their % value scale.  No problems so far?

Okay, here is where my problem kicks in.  When I mine on x11, I maintain a stable 6.1 Mh/s.  The issue is, the dashminer software is overworking my card, and getting worse performance.

When I am hashing x11, maintaining a stable 6.1 Mh/s, my temp never reaches 60c, because I set the power limit to -38 (yes, that is negative 38).  I am using much less power, and increasing efficiency by running cooler.  Yet, my hash rate is about 25% higher.  I snapped a couple screenshots just for a quick reference.
My normal mining on x11:


My mining with dashminer:


As you can see, I normally run at a cool ~58c.  When I run the dashmining, I was pushing 73c, and still only hitting 92.74%.  So, I am burning more power, and dropping efficiency from heat...plus I am running a lot slower in MH/s.  I tried dropping the power limit down to -38, like I normally do.  When I did that, my % value droped to about 50%-55%, and the heat problem still did not completely go away (stayed around 63c-65c).  Obviously that is not realistic.  If I were fine with running my card hot (>70c), I could set my powerlimit back to 0, and then my normal x11 hash rate goes up to around 8 Mh/s.

What gives?  I want to try out the dashminer pool, but I need to figure out why I am having this issue to make it worth the switch.

I'm also running much slower and hotter, but the payout is looking like it will be better than other pools. Still I don't like giving up speed and running hotter. Right now I am just testing things out using the 2 cards that have always been my most stable and have always run the best using the same settings. My 270 is ok a bit warmer but very few HW errors, my 270x though is much hotter and for some reason slower than the 270 when it has always been just slightly faster. In 4 hours and 45 mins I have 28 hw errors compare that to 10 hours on the 270 with only 7. I have dropped intensity well below my norm and tried quite a few different intensity levels but the hw errors still seem to pile on pretty quickly, whether it is overclocked or not. I like the miners stats but wonder why we cant tune the cards as much in the .conf like you could on sgminer, ie. worksize and thread concurrency. I'm sure your already hard at work on the next update to the miner 1.1 did help a little. Would be nice to get close to the performance and temps i had been running on sgminer, I'll keep going with these 2 cards as things improve I'd like to point everything I have at dashminer. Anyone running a xfx 270x black getting better than 40-43% and cooler than 77*, would help a lot to know your settings.

Yeah, my issue is that I am making a good rate hashing at Xpool.  My energy consumption is low, and hash rates high.  If I try and run on dashminer, my r9 290 won't even run a full 100%, and the power consumption goes way up.  So, until this issue can be sorted out, I am making more coin there.

So I tried it out, payouts are great but still I don't like the performance of the miner. To slow to hot and to many hw errors. Why is there always hw errors and why so hot? Doesn't matter how low I set intensity the temps are still to hot and to many hw. Been mining now for almost 2 years and I have never had any trouble like this. The stats and estimate of payment is nice to have on the miner it is not necessary to me, why not allow the use of sgminer. Much better performance speed and efficiency.

The stats and estimate of payment is nice to have on the miner it is not necessary to me, why not allow the use of sgminer. Much better performance speed and efficiency.

In case you are not aware, you can add the --power-tune option in the conf file.  By setting a negative value, you can force the card to run at a lower voltage, so it won't run as hot.  The down side is, you won't come anywhere near hitting the 100% rating.  When I did it, and brought my card down to about 63C, I was only rating in barely above 50% on my r9 290.   This is using --power-tune -38.  With my normal setup, that gets me a stable >6 Mh/s (with x11), and no HW....24 hours a day.  It actually is a quite large power difference too.  Running hot, my 290 will draw a steady 200W.  Running the way I normally do, it stays around 113W.  May not seem like much, but multiply that 87W difference over 24 hours....and you have burned an extra 2.088kW.  Assuming $0.10/kW, I would be losing $0.21 right off the top.  So -0.000714 BTC from whatever I could mine.

Basically, I know my card is capable of running well above the 100% rating, but something is not set right with the dashminer software.  Honestly, as hot as it ran during my testing, and knowing what I get with my normal setup, I should have been pushing a 200% rating. 

A thought has occurred to me, though, which I have been considering for a couple days.  If the dashminer software actually is getting the speed it claims, maybe the miners aren't actually getting full credit for their hash rate.  Using my setup as a reference example, pushing it as hard as the software did, theoretically, I should have been ticking in right around 9 Mh/s.  The software said I was hitting ~92%.  The baseline reference for x11 was 4.84Mh/s.  Double that would be 9.68Mh/s.  Based on this info, my card was running at approximately 93% of that.  That puts a situation where everyone is mining, and only getting partial credit for their hashes. 

Granted, it is a reasonable business model, and it would also explain why the payout is so good.  When you are getting half of what everyone mines....you can afford to be generous in the payouts.  I am just not keen on the secrecy.  If that is what the business model is, I would rather know up front.  Yeah, there would be people who are all ticked off cause they aren't getting full credit.  But, if the payout is better, then it doesn't matter quite so much. 

My only real issue is, I know what I am getting with my normal setup.  I will not run my rig that hot.  It is more expensive because of the power consumption and inefficiency (due to heat).  Plus, it is VERY bad for the equipment.  Personally, I would rather have the option of having to setup a multi-address pool (similar to the way NiceHash does it), and use my own setup.  For people that don't want to deal with the technical stuff, they can use the plug-n-play software. 

Anyway, that is my two cents.

I completely agree with you and feel the same way on all points. Mining through whatever multipool I choose with sgminer 5.1 and wolf0's bin I get 3.7Mhs on each 270 and stay between 65-68*. That tells me I should be getting somewhere around 78% per 270 if 4.84 is 100%. But I was told I was wrong on the math to not look at hash speed even though the website states;
"Our base payout is set to be 0.25 DASH per day plus bonus (bonus depends on luck and coin prices) for AMD R9 290 (our reference card with its speed taken as 100% value). Same hardware achieves 4.84MHs in popular X11-mod miner, so we are using this value for per mhs payout pricing.".  Maybe with future updates things will get better, but there seems to be a lack of transparency that makes me uncomfortable.

Hi and thank you for your interest.

You should not count megahashes on dashminer. Dashminer works with %. Period.

R9 290 is about 100% speed. That will give you 0.26 DASH + daily bonus. Usually, this is somewhere around 0.0038 BTC per day for a single R9 290.

You should compare this daily income with the income that you're getting from other pools and make a decision. Factor in the power consumption / noise / heat.

dashminer.com is not for everyone. I can see that you need to keep your system cool and you only have 1 card... So this pool is probably not for you.

Serious miners have at least a dozen cards, open case systems with additional airflow, etc. They count watts that they pay for and are very sensitive to the daily income they're getting. dashminer.com is targetted more towards such miners.

Thank you!

Everyone has to start somewhere.  I am in it to make money, not just burn electricity.  But, I am not rich, so I have to add to as I am able.  Matter of fact, I just recently acquired a 290x and a water cooler for it.  SHould be here in a week.  I intend to point it to the dashminer server, since I will be able to run it hard without heat becoming an issue.  And, if my upcoming software release goes well, i will have the cash to buy a few rigs full of Fury X's   So, I could potentially go from a single card miner to a small gpu farm in a couple months.  My point is, I like to plan ahead.  I need to know everything, so I don't get caught in a bad way.

And, just for the sake of giving dashminer a sensible trial, I have tweaked the settings (via the conf file), and am running my 290 at 59C-60C for at least 24 hours.  I figured I should at least give it a full run to see how the payout compares to what I am getting at Xpool.  With the settings I am using now, I am getting about 64%.  Doing it this way, i can do a direct comparison based on power consumption vs payout, since I can't do it via Mh/s. 

When I really have time to focus on it, i will probably start looking in to streamlining the mining software....since I am a programmer.

Also, while I am at it, to show I am not just trolling, I will post my bat and conf code, so anyone else wanting to run a bit cooler are able to do so easily.

My "sgminer.bat" file contains:
Code:
setx GPU_MAX_HEAP_SIZE 100
setx GPU_USE_SYNC_OBJECTS 1
setx GPU_MAX_ALLOC_PERCENT 100

sgminer.exe

pause

My "sgminer.conf" file contains:
Code:
{
    "pools" : [
{
    "url" : "ny",
    "user" : "my_user_name_here",
    "pass" : "my_email@my_email_provider.com"
}
    ],
    "device" : "0",
    "xintensity": "64",
    "gpu-threads" : "4",
    "gpu-powertune" : "-34",
    "gpu-engine" : "947",
    "gpu-memclock" : "1250",
    "temp-cutoff": "70",
    "temp-overheat": "65",
    "temp-target": "60",
    "auto-fan": true,
    "api-port" : "4028"
}

This is what I use for my r9 290.  When I add the r9 290x in a week, I will have to change the conf file, but not the bat file.
The changes to the conf file will be to the following entries (everything else remains the same):
Code:
    "device" : "1",
    "xintensity": "64",
    "gpu-threads" : "4",
    "gpu-powertune" : "0",
    "gpu-engine" : "1100",
    "gpu-memclock" : "1250",

The reason only the temp parameters will not be changing is due to the watercooler i will be using.  The NZXT Kraken G10 and X31 unit. 
The temp should stay well below 50C, but this cooler does not water cool the vram.  That is still air cooled.  So, no OC to the memory,
and no increase in the voltage...although the voltage will be able to remain at the baseline 0 level.

Anyway, hopefully this will help someone else wanting to try out dashminer, but not wanting to let their system run hot.

Thanks for your input.

Yes, Fury seem to be great. I am getting Fury Nano as soon as they are available.

How much are you getting at xpool? It is not on poolpicker, so hard to compare with others:



I know that there are many nicehash miners and nicehash paid 0.00032930 per MHs. You mentioned that you have 6.1 mhs. So you'd get 0.00200873 BTC (0.00032930 x 6.1) for 2015-07-27.
I'm using 2015-07-27, because that's the last published date of nicehash on poolpicker.eu.

25-07-2015 payout hash is 802ed5aaaf451e7b839b982482c79e5f075e0e23ccd6c799f34a183d2dffdd6e .  0.003644 BTC per 100% (0.26 DASH base + 9% daily bonus at 0.012859505 DASH/BTC exchange rate). $1.05 USD per 100% (288.22 BTC/USD exchange rate).

dashminer.com paid 0.003644 BTC per 100% on that day. With your "strange" settings of "64%" you'd be getting around 0.00233216, which is 16% more than nicehash.

But as I mentioned before, if you are looking for a "cool & quiet" mining, dashminer.com is not what you want.

If you were using full potential of your graphics card (100% of R9 290), then you'd get a 0.003644 BTC payout, which is 81% more than on nicehash with 6.1 mhs.

Something like this...

PS: There is example.bat in dashminer package. What happens if you don't use your .conf file and just run from command line? I would not recommend setting gpu-threads to 4. "1" (default) is a good value for R9 290.

Thanks for your input.

Yes, Fury seem to be great. I am getting Fury Nano as soon as they are available.

How much are you getting at xpool? It is not on poolpicker, so hard to compare with others:

With my settings I get about ~0.0025 BTC, after their 2% fee, on Xpool. 

It isn't so much that I am looking for "cool & quiet" mining.  I am factoring in electricity usage, and hardware life.  I don't ever intend to get rid of, or upgrade, any of my hardware, ever.  What I intend to do is continue adding to what I already have.  Currently I am pushing 6 Mh/s.  By the end of the year, (assuming my software release goes about as well as it did last year) I project to be running between 500 Mh/s and 1.5 Gh/s.   That will cost me a sizeable chunk of change, and i expect to eventually make it back.  But, to do so, I have to find the sweet spot.  The sweet spot being, highest payout/hash - energy & maintainence costs. 

My advantage, in this area, is my experience with programming and electronics.  I know energy efficiency degrades as heat increases.  There are four ways to deal with this, all of which have their issues. 

The first is to just let 'em rip.  The downside being drastically shortened hardware life, and higher energy bill.  The income will be high in this scenario, but short lived as the equipment will begin to wear out.  Then I have to deal with replacement costs. 

The second is what most farms seem to be doing, which is to keep the farm in a temperature regulated environment.  This helps with the equipment a lot, but running hot still shortens the life of the systems.  The major downside is the cost of cooling when the weather is warm.  Otherwise, this isn't such a terrible option, other than high power costs.  I am a bit on edge about this option because I have seen a lot of farms shut down because the power bill make sit unprofitable for them.

The third is to consider adding in an alternative energy source, such as solar power, in additional to the setup in the second scenario.  This would obviously put a large dent in the energy expenses.  The downside is solar being so expensive to setup in the first place.  Something adequate to drive a 1 Gh/s farm would run > $20k, assuming the person did most of the work themself. 

The fourth is my idea.  Focus on maximum efficiency.  Fine tune the systems to gain the highest number of hashes with the greatest energy efficiency. 

In the end, coin mining is all about sustainable-profitability.  Based on my projections, the fourth is the best way to go.  It does require the most effort, but also the smallest expense.  The effort primarily being in doing all the calculations, and making sure nothing is left out of the equation.  When I say nothing left out, I mean buying the fastest equipment, with the best on card cooling, platinum grade power supplies, low power CPUs to match the motherboards, energy efficient system RAM, and system storage drives, power regulation and battery backups, environmental controls such as air filtering and A/C, and alternative energy sources (such as solar, etc.)

I suppose for having only been into coin mining for going on 6 days now...maybe I have put an excessive amount of thought into it.  But that's how I roll!  Basically, I am testing the concept to see if it can be made sustainable.  If not, then my unused gpu power will just help offset my electric bill (since my main computer is on 24/7 anyway). 

Also, since you asked, i ran the dashminer with minimal options (intensity a @ 22, gpu-threads @ 1, no other options set).  It has been running for 9 minutes, and it is running at 95% @ 72C and drawing an avg of 199W of power.    This is what most people don't catch.  I have left it running now for 15 mins.  The rate has stayed at 95%.  The temp has creeped up to 73C, and the avg power usage is now 201.8W.  Oh yeah, I forgot to mention, the vrm1 temp was up to 92C.  The projected rate was 0.244 DASH/day.  And the fan speed was 100%.

For contrast, I am back to my previous settings.  The projected rate is 0.166 DASH/day.  The hash rate is hovering right at 64%.  The temp is 60C  The fan speed is 85%.  The power usage is avg 121.0W.  And very importantly....the vrm1 temp is only 63C,

Based on the numbers you posted
25-07-2015 ... 0.003644 BTC per 100% (0.26 DASH base + 9% daily bonus at 0.012859505 DASH/BTC exchange rate). $1.05 USD per 100% (288.22 BTC/USD exchange rate).
running with the recommended settings, I would make ($1.05 * 95%) $0.99.  Now I factor in the power usage expense.  The baseline usage for normal activity is about 12W.  So, we subtract that from the avg and get 188.8W.  That give me 4.5312kW for 1 day.  That makes my power expense $0.46/day.  So, my net gain is $0.53/day running the recommended settings.

If I run with my settings-- ($1.05 * 64%) $0.67.  Power usage is 108W, or 2.592kW/day.  Power expense is $0.26.  Net profit is $0.41/day.

Seems like a clear winner, right?  Well, I didn't factor in the expense of climate control, and running A/C or central air is expensive, especially when it is >90F outside and humid.  Plus, this is also using the presumption that the computer is already on for other things (which it is).  If I was running the system for the sole purpose of mining, then I have to factor in the entire system power usage.  Instead of it being 188.8W vs 108W, it would be more like 700W vs 500W, because every part of the system would factor into it, and be affected by the heat.

And then we still haven't considered longevity.  Assuming we manage to maintain profitability over the long term, then we have to deal with equipment maintenance.  At a rate of $0.53/day it will take me 567 days (1.6 years) to pay a gpu if I have to replace it.  So, the hardware must survive longer than 1.6 years (assuming profitability does not decrease) for this to be profitable.  Heat degrades electronic equipment, so over time, the hotter I run it, the slower my hash rate will be. Granted, running slower, it will take me 732 days (2.1 years) to pay for the equipment.  But, running at the lower temperature, the hash rate will not degrade as much, and I won't have to be concerned about hardware failure, pretty much indefinitely.  Basically, running hot, I will eventually destroy the hardware.  Running cool, it will continue to perform well long after it is outdated equipment.  At which point, I can still sell it in good condition, instead of as junk for parts.

Yeah.....so anyway.  It's all about the net profit.  Whatever turns out to be the most profitable, that is what I am going to do.  And, i am hoping dashminer turns out, at least, be competitive with xpool.  I would prefer to have two good places to mine.  Better to have a back up than rely on one location entirely.

I read whole thread and this pool is doing either one of the following things:
- paying bonus coins (not from mining) for now just to get miners (unlikely, because that would fail in future when this stash of coins is spent) or
- more likely as mentioned already, using some "for now private" kernels for mining, giving miners only small cut (or considerably smaller cut, but still above other pools)

Also, it is just a matter of time when someone decides to crack this software and extract kernels and make them run on any pool  Cheesy I am surprised that nobody did that yet. There is no way you could hide kernels once you make them run on miners, especially not if there is source available.

Excellent profits: we quickly add new coins, we have a fast mining kernel, we can switch between coins and algorithms.

So, basically..yeah, this pool does NOT strictly mine only DASH.
