My second ZEC + XMR+ ETH thread builds info links thoughts and photos.

After the ROM mod, trying to attempt any finetuning in AB 4.2 or 4.3 will crash the rig or become unstable.

For 480 case, messing with wattman is no picnic too and I could only get 33% reduction in -mV.

But using the ROM mod as it is, can already achieve 29MHs, low power - just under 1000w for 6xGPUs and considerably less heat.

Without using his low-power rom and using a different one, I have a 6 card rx480 rig doing > 29.1MH/s for each card pulling total 882w at the wall.
That is using Windows and the rom and applying -100 mV drop and it's rock solid (also Biostar motherboard).

That adds a lot of savings when you have multiple rigs!

the current SM Linux @ 6x480 @ 730watts with Heliox rom is running well and integrated with Claymore Ethman monitoring so I am happy with that.

I probably consider your approach too (Boysie's rom?) further power savings but my intention is to move away from Windows as much as possible.

No plans to dismantle this rig since its already ROIed -- but all future build will default to the 4GPU build.

Do you know any details of the mod? I have 470s (non MSI) so its hard to find a rom. So far I´ve only done the 1500er strap mod by myself but I´d like to save some power of course ;-)

most of the mods are "algo-optimised" - no good 4 profit-switcher.

What is SM Linux? Not using Boysie's, using Jukebox's bios. I would *love* to use Linux (it's what i'm most comfortable with) but the power saving from using Windows means at this point I don't have much choice unless I can somehow figure out how to do -100 mV drop for each GPU.

simplemining.net = SM Linux, tytantic's custom build image with ready to mine function, controlled from web master console. All the needed miners are available claymore, SA, optiminer, wolf etc.

nanos and 390s are very easy to do -100mV using AB but I give up on 480/RX cards -- thats why have to resort to mods.

honestly I havent seen 470 mods -- maybe you can start with the 480 mod thread here... the 480 thread is here https://bitcointalk.org/index.php?topic=1584617.msg15910357#msg15910357

There is a mod somewhere for sapphire RX470 4gb reference style. It works well. We can find it easily. (it's one megaupload)

I found a boysie mod for sapphire rx470 nitro 4gb too, but it didn't work for me because there are different clock version of the nitros.
Havent found the mod for mine.

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 ?

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.

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.

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.

[vg54dett]

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 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.

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

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.

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.

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.

[GabryRox]

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?

[GabryRox]

Hope everyone is making money on XMR -- all my 33 rigs are on Dwarfpool XMR.

Win 10, 2 rigs with 10x RX 480 cards total

Claymore's XMR miner works 3-5 minutes and stopped

So have to stick to ETC

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.

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!
