Can anyone help me with this? I was mining equihash on miningpoolhub and my wallet balance looks drastically different than what it should be.
I was mining on stratum+tcp://us-east.equihash-hub.miningpoolhub.com:17023

Snapshot of BALANCES from the BALANCES page:
Coin         Normal Wallet     Auto Exchange Wallet   On Exchange   
Bitcoin   0.00499899         0        0   
Zcash   0                  0 (0.00476578)          0

Zencash   0             0.50708627 (8.15461064)   2.78953693   

But, my earnings should be higher than that, so I checked each wallet and found under zencash that my Recent Credit are as follows:
RECENT CREDITS

So if my recent credits for zencash are 55 ZEN over the past 3 days, then why does my zen balance only show about 10 ZEN. Where is the rest of it? Or does it take a few days to go from CREDITS to your Wallet?

I appreciate any help in clarification. Thanks

Hi! Yes I do. Send me a message on telegram or discord:

Also, these guys are releasing the x7+ maybe end of the month, and the X2 soon (which mines 3 algos including Groestl). Seems to all be in small batches of 200-300 units each.

Hey guys, anyone know how to get miningpoolhub equihash to work for Asic innosilicon A9. I keep getting a dead pool on it.

Settings:
stratum+tcp://us-east.equihash-hub.miningpoolhub.com:17023

Anyone else trying to mine grin with bminer and getting startup errors: "The code execution cannot proceed because node.dll was not found"..."The code execution cannot proceed because ffmpeg.dll was not found"..."The code execution cannot proceed because MSVCP140.dll was not found"...."The code execution cannot proceed because VCRUNTIME140.dll was not found" any suggestions on how to overcome this error would be appreciated!

Probably due to the Festival. It's back up now.

Forgot to update this. The problem was never fully figured out. After breaking down the baikals that caught fire it appeared the ones that caught fire had a lot of dust in between the capacitors on the board. Since there was no conformal coating on these boards (guess Baikal wanted to save a buck or two per board), the dust piled up and during a humid month the dust and moisture allowed for a path of conductivity. I took all my baikals apart, cleaned them and applied conformal coating. I then went back to APW3++ PSUs for the baikals. Since then, no issues. I also haven't had any other APW7 fires with any other units.

Hey guys, @astraleureka is going to help extract the image as I'm not sure how to do that correctly. Will post once we get it. Interested to see what else this machine can do.

Hey guys, I just received two of these units. They work almost as specified. The hashrates I am getting are 262gh/s but the watts are 1,515 watts. However, the cool thing is I found two hidden algorithms in the code: keccak256 and blake2s. I haven't tried activating them yet as my programming knowledge is limited (I could find them, but no idea how to activate them from there). Most undervolting and overclocking that you'd want to do is available in the cgminer.conf file which is nice. Seems to work when I modify it. Will play around to figure out what is most efficient. Anyone else find the hidden algo's and were you able to get them to work?

Thanks guys on the responses/questions!

My farm runs on 3 phase 4 wire to the PDUs at 240volt, and then the PSU plugs into the PDUs.
I checked the PDUs and they are all checking in around 230-240volts at the receptacles.

I do profit switching with the Baikal BK X, so they range in power draw from 120watts to 630watts depending on which algo they are on.
The APW3++ is setup for up to 1600watts. Specs: https://www.eyeboot.com/antminer-apw3-bitcoin-power-supply.html
The APW7 is setup for up to 1800watts. Specs: https://shop.bitmain.com/product/detail?pid=00020180621115441375Ioit8oeJ06DE
I have one PSU per each miner and no PCI splitters are used.

I upgraded as the efficiency of the apw7 was 1-2% better than the apw3++ and I was able to buy the apw7 and sell the apw3 for about the same cost.
Today I went through and removed the apw7s from the baikals and re-installed the APW3++ PSUs instead.
However, all my other machines running the APW7 have not had any issues, a mix of Innosilicon D9, A9, S11 and Bitmain S9i.

I have an electrical engineer coming on Tuesday to see if we can diagnose the issue too.

Thanks for the feedback!

A few days ago I swapped all my APW3++ PSUs for the new Bitmain APW7 PSU units on my Baikal BK Xs. After day one, I had an electric fire that melted one of the hashboards on a Baikal BK X unit. The next day two more Baikal BK X units end up with melted hashboards. All 3 damaged Baikal BK X units had APW7 PSUs, and all 3 had the far right dashboards melt. The other hashboards appear to be ok. I found 5 of the capacitors had fallen off the melted hashboards (see pics).

Anyone else having issues with either the APW7 PSUs or Baikal BK X (Giant X 10) units?

Here are some photos:

Thanks!
So I went back to the Baikal IP dashboard, deleted all the mining pools, and added the pools I wanted. They work fine on the Baikal unit. Then I went to awesome miner and added the same info on there. When I try to re-prioritize the pools in AM, it works (kind of), then the miner will process the new pool BUT with the incorrect algorithm. For example I made a Nist5 pool the top priority, the miner switched to that pool, and then starting mining on that pool, but was mining as if it was a Quark algo.

I have a Baikal BK X. When I edit the mining pools in the IP dashboard they work just fine. When I add a mining pool into Awesome Miner and then change the mining pool for the Baikal BK X via awesomeminer the mining pool info seems to all be correct, but the BK X then processes the wrong algorithm.
For example for quark zpool mining pool when initiated through awesomeminer, the BK X processes X11 instead. I can't figure out how to change or fix it.

EDIT:
On the baikal IP dashboard, I deleted all pools, added the pools in the priority I wanted and then saved. Everything works on the Baikal. When I then go to awesomeminer, if I re-prioritize on AM the same errors happen (mining the wrong algo on the pool selected). Also, if I just disable all the pools so that only the pool I want to mine is enabled, that seems to work (very low rejected shares), but AM still says it is mining a different pool than it actually is. In summary, just seems like AM and Baikal do not work well together.

Thanks!

Rejected shares error help with awesome miner!
I am setting up Baikal BK X units through awesome miner. When I input the mining pool information directly onto the miner's dashboard (under the Miner tab through IP address) the miner works great and mining pools accept the shares. When I input that same data through awesome miner and tell the same Baikal BK X to mine to that mining pool, it has an 85%+ shares rejected rate. Tried adding /#xnsub, tried removing and adding the stratum+tcp:// at the beginning and still get the same result. After I restart and it goes back to the mining pools I saved on the Baikal's dashboard it starts working again just fine, so there is something that awesome miner is doing to the pool URL, or other programming that is making the pools then reject the shares. The pools I am using in awesome miner Nicehash, Mining Pool Hub, Zpool... examples
