Well, I had x4 S9 miners running around 52 TH/s on this pool this morning and only made around 375 DGB. This is grossly less than what was expected from whattomine.com

I am not sure if I was doing anything wrong, but I feel that this output is way too low. According to the pool statistics, I should be making around 86 DGB /TH/Day. This amounts to about 4,700 DGB per day, which is still far-removed from the 7,400 DGB estimated from whattomine.com. So, if you take the 375 I made over 3 hours on the pool @ 52 TH, that's around 3000 DGB a day, and there is no way I would mine at that profitability.   I would like to mine this coin, but cannot afford to do so when other coins are more profitable.

Is there anything that you would suggest to increase rewards per day? Or does this all sound normal?

Thanks

Ok, I am on the pool now at ~ 54 TH/s. My questions now are, about what is the expected reward? I.e. how many digibyte will I receive /TH/Day. According to whattomine.com, 54 TH should be pulling in about 7,400 DGB/day, yet my pool stats show around 2,500/day. Will this change the longer I am connected to the pool? Other miners @ 54 TH are mining about 5,500 DGB/day, which is still 1,900 less than whattomine.com projects. Do I need to set a higher difficulty to receive more reward? I am just trying to see if this is more profitable than mining other coins at the moment. I believe in the long-term value of Digibyte, but I also want to follow day-to-day profitability. Thanks  

Looking to set up x4 s9 on the pool. What are your estimations on daily dgb for 54 Th/s? Also, I tried using the stratum posted, but it said pool was dead. What did I do wrong? Do I need to put a difficulty? I am just using the antminer firmware to connect to pool. Please tell me what I need to enter in order to connect and start mining! Thank you!

Hi All,

I am a beginner miner, and have been mining with x4 S9's for 3 weeks. I started using NiceHash and ViaBTC because of ease of use, me being a noob and all. I really didn't know any better and just wanted to get up and running. After Nicehash fell last week, I turned strictly to ViaBTC for BCH and BTC mining. However, now being into the game a little more, I am starting to question if ViaBTC is really the best place to be mining long-term.

Anyway, I had heard many good things about Kano Pool before I had even gotten my miners, and was thinking of joining here first. However, then I heard about 'ramping-up' and got a little gun-shy to be honest. I still have no idea what this means.

I am seriously considering joining this pool, but would like a little more information to make my decision. I understand that there may be biased responses from active members of the pool, but I would appreciate neutral comparisons to other pools, as well as legitimate reasons as to why Kano Pool is where I should (or should not be) mining.

Thank you for taking the time to read this, as well as thanks for your response(s) in advance.

Ok, so if the power draw is 1450W, then 1450*4=5800W. If the circuit is 240V, then it would accommodate 7200 watts. 5800/7200 =80.5%. Thus, if the circuit is 240V, then this is totlly possible to run 4. Please tell me if this reasonable.

'if  you do 220  and not 238-242  

you will run 3 not 4'

I don't know how that makes sense. If the math is done correctly, it is 5400 watts on a (220V x 30A) 6600 watt circuit. 5400/6600 = 81%. If the rule is no more than 80% continuously, then this will work, yes? Can you please explain why I could only run 3 and not 4 on a 220V outlet?

So, the electrician is coming tomorrow morning to get me set up to mine with x4 S9's. I am still a little unclear as to whether or not I can put all 4 miners on a 30AMP circuit, but I don't know what other choice I'll have. My concern now it that the APW3++ PSU are 1600W. Does this mean they are always running at 1600W or that is the maximum that they run at? I will be receiving the late November batch of S9's and they are rated at ~1350W. Thus, 1350 x 4 = 5400W. If the 30A circuit has a voltage of 220, then that is 6600W....5400W/6600W = right around 81%. Close enough to run continuously with no worries? However, if I am wrong and the PSU's are always running @ 1600W, then putting 4 on one 30A circuit may not work. Can someone please clear this up for me? Do the APW3++ run at 1600W always? Or, is that just the maximum that they run to accommodate whatever device they are dowering?

Thanks in advance!

Thank you for your thoughts, fanatic26. I will likely try plug and play first and see how it goes before updating the firmware. I even spoke with nicehash customer support and they said it was not necessary to make the miners compatible if it was the November batch. Wish me luck!

Obviously, I am looking to make as much profit. I was recommended on using whattomine.com to determine day to day pool profitability. It seems that Nicehash is always at the top of the list for the SHA-256 algorithm. It is currently around $17.50 per miner per day to mine on nicehash (@$0.09/kWH) with an S9. Is there another pool you would recommend to increase that profitability?

Thanks for your feedback, NotFuzzyWarm. I really do appreciate you taking the time.

I was thinking of mining with nicehash and came across this: https://www.nicehash.com/asic-mining#sha256

Here it states that the antminer S9 NEEDS FIRMWARE UPDATE to the current version. Is this true? If so, why?

Sounds good. I'm glad to hear that I won't have to deal with firmware updates much if at all. Being the noob I am, I am glad to know that I can plug them in and they are ready to go!  Thanks again!

Thank you for your expertise. I did in fact read the entire S9 manual from BITMAIN's site. No where in section 6. 'Administering Your Miner' did it give me the warning you did. It just gave instructions for updating the firmware. It did not specify when or why to update, and it did not say that it comes loaded with the latest version. I am just starting and do not know the intricacies of these machines. That is why I am here! So, thank you!

Hello All,

I am a beginner, and I will be receiving my S9 antminers in a couple weeks and was wondering about the firmware update. First of all, what is cgminer and will I need to be using that? Second of all, when it comes to firmware updates, do I need to do them all or just the latest? I see on BITMAIN's site they have 5 total updates for the S9. Any ideas on which one(s) I will need to download for a 13.5TH S9? Thank you in advance!

Will this PDU suffice?

Not sure why you recommended that outlet. I have pretty much free reign to install what I need with the electrician, so I will likely go with the L6 outlet.

Thanks Beerman,

That all makes sense. I think the live amperage is helpful, but I'm not sure I need 30 outlets since I'll just be running 4 miners. Do they make smaller 30AMP PDUs for cheaper? I plan on running them continuously, or at least for 95% of the time. Also, the wiring actually runs along the ceiling of my basement so it could probably be changed if necessary. I looked at the existing outlet and there were only black, white, and neutral(copper)...no ground. Will this mean that the electrician will need to change the wiring anyway, or is there an alternative?

I really appreciate you taking the time to walk me through this. Please excuse my naivete.

I am still unclear here. I have already bought the PSUs. I got an APW 3++ for each miner. I am hooking up 4 S9 miners to this outlet. How is a 16AMP rated PDU enough for this set-up? Even with the right PDU, will a 30 AMP circuit be SAFE for this set-up? What cables will I need to connect the PSUs to PSD? I really just want to be clear before I take action, and I am now hearing conflicting information from the responses I'm getting. Thanks in advance!

Sorry for my noobness. I just want to get everything right before the miners come so I can hit the ground running. I also hope to keep from frying the miners or my home.

The receptacle is a NEMA 10-30 3-prong. I know not the voltage, but the electrician should be able to test it. I am having him install a new outlet. My concern is, if the 30AMP circuit currently has high enough voltage, are all PDUs derated to 24AMPs? If so, how would 24 AMPs be enough? Do they make 30AMP rated PDUs? What if I had the electrician install a 40AMP breaker? Would I need a higher AMP PDU? Sorry, but I am new to all of this and don't want to fry my investment, or my house.

So, I just purchased x4 S9's and am looking to have everything ready to install the day they arrive at the end of the month. I purchased x1 APW 3++ for each miner. I will be running these in a cold (50F) basement over the winter. My plan was to hook them up to a 30AMP circuit formerly used for a clothes dryer. If I cannot safely hook up to a 30AMP breaker, I will have an electrician install a 40AMP breaker for the antminers. My questions are, what PDU will I need to buy if I am using a 40AMP breaker? If I can use the 30AMP circuit, what PDU should I get? I really only need 4 ports in the PDU @ 220V. Also, what cables will I need to buy to go from PSU to the PDU? Any help would be greatly appreciated! Thank you in advance!!

I too have x4 S9's that I am planning to hook up when they are delivered at the end of the month. I ordered the APW3++ PSU for each S9.
