That's good, don't forget to makes that soundproof box was able to handle the heat that produces by your machine. Adding some cooling systems may help (DIY cooling systems) don't let your machine sweating. LoL

For the past few years, I lived from Crypto mining. So, I can say for sure, you can. But the problems is how experienced you are on this Crypto mining world (related to this current situation [as above advice])

Personally, I keep buying mining stuff on this current situation. But it will differ if you are new to this mining world moreover you can't take any risk since you need to produce some profit as fast as you can at your conditions (as you said: need to support our daily family sustenance). But if you want it, I'm sure you can do it. 

That the point how merits come to us:

---

I collect a bit merits so far (21) since merits system exists. But most of my received merits come from my post on the technical board (Altcoin [mining]) that the most mastered by me. You will felt "hard to get merits" while you want to receive it.

Just forget about merits (merits is nothing) and keep posting on the things that you mastered the most, keep spread positive things, be useful and merits will come to you.

As the other comment said, Undervolt would give you a bit lower power used, and some different algorithm may be giving you less power consumption. In the end, this is related to power cost, so you can stay at that power used but increase the profit with mining more profitable coin than the current coin.

Of course both side (that's why called as soundproof). Are this is DIY soundproof box? You also must be considered about heat handler (as above said), many ways to do it. May you should be made DIY cooling systems and add it to the box.

You could have one additional PSUs for powering the risers (as above said), as long as your 2nd PSUs produce the right voltage it will be working smoothly.

If you plan to use one only PSUs (your current PSU), use all 8 Molex cable to powering 8 risers, and the other 4 risers using Sata (one rail per riser) one of this Sata must use to powering risers and also SSD. Each card (depend on the brand, series) has different power management (we have zero control over it), I hope your card pull a bit power from PCIe bus.

Maybe you need to post your coin config here, so we can analyze what was wrong with that coin(.)conf. And also give us a bit information about what you have done (e.g., your miner config)


But soon it will be increased, cause you were giving this info to the public. 

With that electricity cost, you could do much research to find the best coin to mine, without worrying about the electricity bill. I've never stayed on one coin for more one month. I have one rig that used especially for doing coin research, but still worried about the electricity bill (my electricity cost was hight enough).

You do a right thing with doing mod by yourself. At least, now you have known how to mod your bios card, and also you save your card from possible terrible things happened with flashing your card using downloaded bios from somewhere.

I'm sure that was a glitch. Your GPU 0 got an incorrect share, and I'm sure the GPU 0 hasn't any share to the pool (check it) that's usually caused by OC setting (you need to lowering it)


That's shown that only one card worked and had a valid share to the pool.

Dummy output (Dummy display) means connecting a display adapter (usually I use HDMI adapters) without connecting it to the monitor.

That was one of AMD's card issue and happened to a few series while used for mining. Not always, but sometimes it was happening.

Finally, I saw Jet Cash with a few posts on Altcoin (mining) board.

Will be better to do Altcoin mining as your learned object than Bitcoin.

With your current device, a bit hard to say you were on a right move (even if it just to learn about mining). Bitcoin mining, moreover doing Bitcoin solo mining with your current device, that had left by miners more than five years ago (that device, too old for Bitcoin mining).

But whatever it is, you still can do Bitcoin mining with that device for learning "how to" do Mining only. But I suggest you choose any other coin (Altcoin) that mined with the kind device at least 1-2 years ago or may newest coins (that's okay)

Solo mining to a solo pool isn't giving a much different with a pooled mining (on the process and how to do it), the one that makes it different is only payment (rewards). So if you really want to learn about mining, you can do solo mining to the official wallet (QT-Wallet), and on the other side, you can do pooled mining, that's better. IMHO

You can use Operating Systems that you most mastered. If you most familiar with Linux (as you said you were using Kali) then do with it. I can tell, I felt easier with Windows, it because I am Windows user, it maybe will different with Linux user.

Have you tried to re-mod your bios card? To make sure you were doing the mod with a proper way.

One other thing that may you need to try is giving that card (the troubled one) dummy output but no need to connect to the display.

Ah, I see.

That product (Breakout Board Adapter) was compatible with your PSUs. As the seller said

Compatible with server power supply:

In fact, the first product title (Amazon) been answering your question.


"SYTIVE PSU Breakout Board Adapter for HP Dell 750W/1200W/1500W Server Power Supply Ethereum ETH ZEC 12V GPU Mining."

Mean, you can use server's PSUs to powering your rigs. And that's better than while you are using consumer's PSUs. Server's PSUs designed for running continuously (the durability must be better).

First of all, you need to describe your full setup. It will make it easier to analyze your problems.

Which Cards are you using?
Which OS are you using for run your rigs?
...
...
...
and many other things as detail as you can.

I was suspecting that was the driver issue after some system crash (if you are using Windows [since you were mentioning the bat file], it may cause by Windows update) I'm not sure since we have a bit info of your setup.

Clean the driver (using DDU) and reinstall it may fix your problem.

OP thinks re-loading Claymore will fix OP's problem (as shown on the OP's first post) but then OP giving us (3rd post) error message that appears on OP's Claymore:


So, what was OP talking about is incorrect share.

I think that was everyone question. And asking here wasn't a proper way to get the best coins to mine.

Why was that less proper way?
If you plan to speculate to mine the coin that has a lot of miner on it (at least you have one rival [miner that posted coin name here, and this miner mine this coin too]) mean you have a bit chance. Just do your own research for the best result!

To re-load the Claymore config, you can press "r."

You can fix the problem you are facing (incorrect share) with lowering your OC setting. You could try to reduce your OC setting bit by bit (until you get the right one setting) or bring it back to default setting then increase it bit by bit.

I'm not sure your new mobo causing it.


Code 43 usually related to device hardware fails nor fails on the device driver, I'm not sure which one that was you facing. Maybe you need to try to re-flash your bios card, then reinstall the driver (try a few drivers versions)


Have you also tried using another riser?

As a standard operation for Polaris cards (modded), in case you forgot to do this:
