12 cards, can be made one or two rigs, seem like no need too much space. You can build vertical open-air rig case for reducing the dimension. How about electricity issue? Like I said above, you can start to run half of your total card if your electric power isn't enough to run all of your cards.

---

As your reference:

With that KWH cost, just go to start mining at least with a half or a few cards only, at your place. But may you need to pick another coin.

Space: With half of your total cards, I think you can put it anywhere, but keep to think about air flow.

Lacking power: If you didn't install all of your cards, it would reduce power consumption, may you can run it.

Except you can re-sell it ASAP and at a reasonable price, of course, I think would be a bit hard to do it in this current situation.

In the end, worth or not also will be compared to cards prices itself. And the other thing what makes some cards worth or not is yourself. On the skilled hands, old cards (with costs under $150) may still worth. Forget about what you can't control (coin price, difficulty, and another thing that you have zero control over it), focus on what you can control (you know what? find it yourself)

My best mining moment may December of 2014, mine XPY (Paycoin). In Miningrigrentals, NiceHash, WestHash, SHA 256 Algo full of rented. Renting price rises to 500%, may more.

My first one hour, I spend 0.17 BTC (for renting hashes), one hour after, I got almost 2 BTC. Short story, in that two weeks my total profit around $ 30,000.

Maybe someone still remembers this moment? GAWMiner?

Other best moment, when I'm using Antminer S1 on BTCGuild.

---

Oh yeah...also zcash moment, I started mine from test-net (using my VPS), damn. I have been ready when genesis block launched. (I started from zero)

Nop, that code must be applied to file named start (bat file). Located in Claymore folder (same as epool/dpool text) the last one in below.

Your code for dual-mining must be:

I felt super agree with this two reply post:

I've never use SMOS, even I don't really know hows it works, from what I saw (at your pics), report and monitoring were in a web-based system, that's giving you more reason that glitch possible between client and server (Correct me if I'm wrong). imho

---

Back here cause I see an update on this thread, then curious to check back your picture. This is my suggestion (out off topic, indeed), may you need to blurring your sensitive info such as email address that shown in your picture above. 

I said flash (short time - in a second) increase (mine), and I was using Claymore, then glitch (Software nor Hardware) refer to my condition. I didn't tell yours as a glitch cause have enough time to take a picture. As you said your card hashed around 46.89 to 46.91 may you are lucky, one in a million.

Is your card still hashed around 46.89 to 46.91 (atm)? If that holds out in the long-term, it's more like a miracle. (same as your post title.)

Ah..this is a good idea.

My pleasure.

I'm just trying to do something better here, Joe. It was clear enough hows Merits systems work. And what you were doing with this signature challenge is one a kind way to distribute sMerit and to keep our forum better.  I am proud to be a part of this.

Keep going, Joe! 

I have one same experience with my Power Color RX 470 mining edition (Red Dragon - 4GB), before. The card was modded, It happen before I OCing this card. Using Claymore (mine ETH), it was a flash increase (even I didn't have enough time to take a picture) to 58, but after few second going down to normal hashes. More like a glitch in software nor hardware for me.

Ah.. good idea, they can heating their rooms, then pay their electricity bill using mine outcome.

And the bolded one must be OP's consideration, lol. Maybe you can be a negotiator for this transaction. (am sure OP would giving you a transaction fee) 

What should you do?

Of course, optimizing what you have now. Maybe you in bad luck when you were purchasing those L3. It's worthless if you complain, you regret something that has happened, you broke.

Keep fighting; you have a weapon, set your strategy, fight. Yeah I know, that's not easy, but don't lose without a fight. I can say for sure to you, in this current situation (when most miners felt mining isn't profitable again - Especially GPUs miners) am still profit with my GPUs rig.

Bitmain is a good company?

In your situation, maybe they not a good one. But remember they are doing business. Honestly, for me blame some party for what happened to us isn't wise at all.

Ah...you got another option with more specific experience to your cards. -OP



Buddy, I always liked R9 owner, that's really cool. I have a few R9 series (290,290X,390,390x) and 16.9.2 giving me the best performance on those all card.

Another story - my friend (that I mentioned above) use hybrid driver (may I need to ask him back which driver source that used) to combine Fury with R9 390 in one rig.

OP said, was able to see mining status in the pool, before. But then, when OP's worker goes off, even after connected again, OP can't see mining stat on the pool. (that's what I get)

Seem like not a wallet address issue, except OP changes the address itself. Or maybe changed itself, like you said, but can it be?

OP- did you know how to check your mining stat through your wallet address? Use the same wallet address in the bat file. Maybe you need to double check your wallet address like leonix said. 

Merited: https://bitcointalk.org/index.php?topic=3283912.msg34255059#msg34255059 (Chosen by me - Sorry Joe, I always choose by my self)

You did good, max2607. Congrats!

Joe, seems I run out of sMerit, so next round I'll provide one (1) merits only, for third place.  

I have some experience with R9 Fury and Fury X, but that's not my own, that's my friend cards. Fury gets the best performance (almost in all algorithm) using driver 15 version, indeed. And Fury X better with driver 16 version (16.9.2 - if am not wrong.  ) Maybe you could try 16.9.2 with your Fury.

I don't get it, what you mean with upgrading IP address?
That what you mean IP address on the Ethermine setting section? If it yes, it doesn't relate to your pool worker going off. That setting (public IP) related to securing your pool account, just it.

If you get a message saying that "invalid IP address". Try to point your rig to that pool (Ethermine) at least until one share, then check your public IP through https://whatismyipaddress.com/ or something else, then put it on Ethermine settings section.

Technically, when your mining software (in your case, Claymore) showing hashes then giving a valid share to the pool, mining pool must be showing your mining stat (Ethermine, Nanopool). I have no idea with your case. 

OP only wants to know how to start mining. You can suggest how to do it including device needed. If you are ASICs haters, you can recommend GPUs, simple.

-OP
A lot of suggestion has posted here, So you can start with knowing it. Started with basic knowledge, technical and so on. Feel free to come back here when you get in trouble.

The best choice may include server PSUs that posted above me.
Have you checked the link given by nuanicaj, by the way? it would be meet your requirements.
Talking about durability, Of course, those PSU can run 24/7 safer and also customizable PCIe cable with your needs.

Thanks.

My pleasure! 

Good work with your infographics, buddy!
Maybe someday when I was to create a new post nor other projects, I'll ask you for helping me with your infographics.
