Well.. That is one factor and the last factor is reward. Every X amount of months / years, the reward halves.

Just wanted to update the status my move to Windows 10 on my 2nd rig, in case someone already here or who finds it in the future was grappling with the same issues as I was.

Firstly, I decided to go with the "add each card incrementally" approach instead of swapping out 1 by 1 to mod the bios then replug them all 1 by 1... and this worked, at least for the most part.

After upgrading to W10 (took a bit over an hour), the main thing I did differently from the W7 build was start with the x16 slot #2 on this mobo.  In fact, I did this even before updating windows (had only 1 card plugged into the x16 slot) and it actually worked for the first time on this rig!  So, after installing W10, just left it there and it worked fine.  From there, I just added GPUs 1 by 1, testing with Claymore ETH miner, then flashing bios, then rinse and repeat.  Was really worried before turning it on with GPUs #5 & 6 plugged in, but W10 had absolutely no issue with this whatsoever! So, I now have MSI 470 4GB Gamings in slots 1-5 and the Sapphire Nitro 470 8GB in slot #6.

The one unexpected thing I did run into was this... when copying the ROM from my newest MSI GPU (just opened &received a few days ago), I noticed that under memory type it actually showed Samsung, not Hynix as my other 8 MSI 470's showed.  The other interesting thing is that this GPU actually got about 2 Mh/s more on ETH out of the box than my other MSIs.  But, since I wasn't sure if that Samsung vs Hynix memory could affect the 1500 memory strap, I just left it un-modded, so it is running about 4 MH/s slower on ETH (over-clocked & under-volted) compared to the other MSIs on this rig. Does anyone know if this will affect the memory strap mod at all?

So... bottom line is, testing on ETH miner, I switched over to Claymore XMR 9.6 and actually getting almost exactly as expected, a bit over 4Kh/s (~700 each from the 4 modded MSI and ~600 each from the un-modded MSI and un-modded Nitro). So, very happy with this so far and maybe a bit of room to tweak for further improvement.

No, all totaled with 10 GPUs and 3 i7 K's, I am getting about 7.6 Kh/s on XMR, using about 1,260 watts total. At current rates, about a bit over $10 profit/day (not counting BurstCoin mining). This is the best it's been in the 3-4 months I've been involved in mining so hoping it lasts a while  

Thank you, Phil and buysolar!

LiFePO4 batteries are not flammable and can be purchased from China relatively cheap (all we know that it means to buy from CN, but it is really good price). These lithium phosphate batteries lifetime is around 10 years.

I thought about selling excess of electricity to grid - but rates in NM are not very good.

Hail state around us is Colorado. Those guys are really bad with that!

I was just at buysolar's house.

send him pm's with any solar questions.

Here is what I can offer.   Batteries are costly and die fast.  You need a lot of them and like a can of gasoline they are stored energy (i.e fire + explosion hazard)

Buysolar and I are in a good state (New Jersey) with good solar energy rules he is tied into the grid.  So we sell excess in the day and buy back power at night.

Some states are terrible with grid setups some are better.



Battery only makes sense if you can score batteries cheaply.  Plus place them in a place that does not burn down.


Another thing to think of is hail storms.  NJ  can go 10 years without a hail storm.  I personally have live here for 24 years  and have not seen a storm with dime sized hail.

I am sure many midwest states and central states are laughing at that.  I had a friend in Kansas that has seen hail bigger then golf balls more then 10 times in her life.  I would think that size hail would be hard on a panel.

Depends on the country / size...

Batteries .. no.. too expensive / no one knows how long they will work

--

With 12c / kwh.. I don´t think that it´ll make sense.

If you already own solar panels.. and pay something like 28c... than yes.

Hi there.

Myself and couple of people here asked on using solar panel for mining. Usually how much will be installation of 10kWh? Is it possible to use a batteries to mine from them during night? Does it make send to do if the electricity price is ~12c?

Thank you!

Bump for phil

I had the same issue at first... getting the black screen/freeze-ups/etc after starting it a couple of times. But, once I backed off my undervolt settings a bit it was fine. Been running smoothly for close to 24 hours now and even with a bit less undervolting, the rig is still consuming about 110W less then mining ETH, so no big loss there.  Hoping that Claymore releases a new version of this soon as I suspect there is at least slight room for speed improvements with rx 400 series cards.

Is their any resource that explains the main contributing factors to the difficulty of a given coin?  My impression as a newbie to all of this is that it is either solely or mostly driven by the volume of miners pointed at a given coin.  For example... price of XMR goes through the roof, everybody and their brother switch their rings to mine XMR in the last 2 days and bam! difficulty rises 20% in that time period. Similar thing when ZEC came out and most people started mining it... both XMR & ETH difficulty bottomed out.  Is this the only main driving factor or are their other things to consider?

Agreed Hotmetal... for speculation purposes there are other/better ways to do things than using the existing profitability calculators... but, you can still leverage some of the data to get what the OP wants i think.  For instance, both WTM & CW provide estimated shares mined per hour. So, you just extrapolate that times what you think the target price of your coin will be and you can easily calculate your hourly income. Then, just subtract either your own calculated electricity cost or the one provided on either of those sites and you have your target/future profit per hour.

Sorry about the issues with that evga mobo, Phil.  But a big thanks for reporting the problems here so that the rest of us can avoid that board in the future. I am personally locked into ASRock BTC Pro R2 for my next build since i bought 2 of them a few months back. So, really hoping I can get 6 GPUs running on that (gonna spend most of today on it) and then just repeat the process for that 2nd board.  really hoping that 1200w Rosewill PSU comes down but may consider going with 1000w and just dedicated that rig to XMR only since it sucks so much less power than ETH and even ZEC.

you can't really do what vg54dett wants using a switching program.

you could override a coin by setting a false value to it but then your software would pick that coin to mine.

I guess you could favor a coin with false values but it is just so much easier to use you program with ½ or ⅔ or ¾ of your rigs and just use the remaining rigs on the favored coin.

you get the benefit of switching  with however many rigs you want

you get to take the risk with a favored coin as mine and hold with however many rigs you want.

I'm not sure using network difficulty is a good way to predict things. Need some suggestions.

I think you're maybe trying to solve a problem that doesn't exist. If you "believe" in a certain coin for the future, that is fine and you should stick to it.
If you want the same balance of each alt, that too is easily done and you don't need a calculator for that.

However .... I'm already giving you the most profitable coin (factoring lots of inputs that all the calculators do not factor in).
If you're after a prediction for the future most profitable, that is something I could try to do separately like this:



This causes network difficulty swings to have exaggerated effects on the profitability model.

my thought was: because profitability is modified by price and difficulty, depending on your strategy you may want to mine what is easy to mine to hold as much coin as you can.

Sometimes price goes down, but depending on your own feeling you can expect a better price soon. In that case, it's better to continue mining even if calculator say it's not good because of the actual price.
For example Phil think ZEC will grow, so he can't compare easily profitability for zec through the usual calculators.
Same for me with Eth, I think it will grow again.

I don't know if many people would be interested by such features. For me , the 4-5 main Alts vould be enough. Of course it's not a life or death question.
In the good old bitcoin wisdom calculator you can change all data, including BTC price and it is someimes interesting too for projections.

I think he is better off ½ with your program switching

and ½ simply mining the coin he thinks is lucky zec in my case.

Hand adjust your hash rate until you have your current balance and then change the pricing.
It is something i can code but what would the point be? How granular would you actually want it? Just 1 coin? There's a lot to consider.

You simply can't do that easily.

It is more of you do a switching strategy   or a mine and hold strategy.

You could do ½ with hotmetal's switching program   and ½  with mine and hold.

Say 4gh always switching  and 4gh mining zec and holding

then each day at the exchange holding the zec  you can put in a sell order for ?

in my case I am 100% mine zec and hold  .  I list sale at .062 / .065 / .068



the evga 4 card board sucks  it turns off every 3 to 5 hours I only have 2 cards on it and it still happens.

Do you guys know a way to put your own coins price in mining calculator (such as coinwarz or whattomine) ?

When you have a "hold" strategy, and expect a coin to rise, mining profitability would be more accurate for you if you can calculate it with the expected price instead the actual one.
But I don't know if this is possible ?

@hotmetal : maybe it's an idea for you ?
