I applaud your creativity for begging. That transaction was nearly 2 years ago though...did you just now realize you're down a bitcoin? Seems a bit fishy, but if this is real damn I'm sorry that's a terribly costly mistake to have made. Hurts way more now than it did back then I'm assuming. Otherwise, you get an 9.2.5/10 for creative begging that pulls at everyone who's ever misplaced a decimal in a transactions heartstrings.

Any interest in selling the unit as-is? I'd give you a 100%+ ROI on it...

FWIW all I am going to do is take a heat gun to PCBs and attempt to ghetto reflow them...might make them temporarily work, might not do anything at all. I'd spend $250 to give it a shot though if it's an S9 with 3 bad boards.

Awesome, thank you for the reply, that completely answers my question as all of my units are auto-tune!

I've searched and couldn't find a clear answer to this.

I own several S9s most are 13.5TH, but I have a 14TH version as well. I have had a couple of hash boards fail and chose to break the seal/void the warranty and send the individual boards off to BitmainWarranty for repair out of pocket and run the miners down a board vs sending the whole units to Bitmain for warranty service (hoping this is the smartest decision financially). BitmainWarranty has now spent almost 2 months attempting repairs with no results or even the ability to tell me if the boards can be fixed...but I digress.

My question is can I run different frequency hash boards in the same miner? If so, am I better off putting the 14TH boards in a 13.5TH unit or can I attempt to put one of the better performing 13.5TH boards in the 14TH unit? Basically I want to consolidate my units so I don't have several units running down a board. If anyone can provide their experience with this or what my best course of action is it would be much appreciated!

Giving this a shot now on my 14TH/s version. It's had 1 board (chain 6) acting up over the past few days....sometimes it comes online and only detects 12 asic chips and reads a temperature of 15*, sometimes it detects all the asics but outputs 0 hashing power, then sometimes the hashing power output for the whole device shows 0 when in reality it's cranking out the normal amount.

When it does work it seems to only work for a day or two until some of the hashing power starts dropping off, yet the miner status page shows it as hashing at full speed. Usually a reboot or a shutdown temporarily fixes the issue, but this last time it was giving me issues several reboots didn't remedy the problem...the board would come online with all 63 asics detected, but no hash power.

So I'm attempting your fix right now. Shut the unit down through command line then killed the breaker to it, let it sit momentarily while disconnecting the network cable, flipped the breaker back on and am letting it try to connect/reboot itself with no connection. Will be plugging in the network cable shortly and hoping for the best! Will update with my outcome!

The whole family is sacrificing USDA prime thick cut sirloins, Yukon gold garlic smashed potatoes, and bi-color corn on the cob for the block that's coming tonight. Hope that's enough to satisfy yee ol' block gods!

FWIW I ran on NiceHash for the first week of November and they were paying in the range of .00018 - .000185 per TH/day throughout that time.

I guess my other question is when do we know when BCH is more profitable to mine than BTC, I know we can use calculators, but a calculator is not the same thing as real world results. I know some pools have setup to auto-switch between the most profitable, I like this idea if executed properly. Anyone have any input on this or mind sharing their game plan as BCH is climbing in value VERY quickly...


You're talking about the same fork, NYA fork is/was referred to as B2X

I'm going to ask a noob question here as I can't really find a solid answer. I've referenced the site whattomine to check profitability of mining different algo's/equipment/etc, but I am questioning the accuracy of it's estimations. For example, if you were to put in the specs of an S9 and check current profitability at the current difficulty it has BTC as the 6th most profitable SHA256 algo. Obviously these results fluctuate constantly due to many factors and the filters you select, but it just doesn't feel like an accurate estimation is being portrayed.

Over the past month or so that I've been mining and looking at the site its show than mining via NiceHash was almost always more profitable than mining BTC. I mined on NiceHash for about a week and if I compare my BTC per TH/day to what the forum members reported as their average at Kano pool over the last 3 months (when luck was pretty bad for the pool) mining with at Kano was much more profitable, by something like 30% even with the run of bad luck/difficult blocks.

I guess my question is how much trust should one put into a site like whattomine and how do you truly calculate what the most profitable use of your mining power is? Currently the site is showing BCH as being $0.45 per TH/day more profitable to mine than BTC, but it also says NiceHash is $0.25 per TH/day more profitable than BTC which I know is a fallacy.

If someone can chime in with some more information or point me towards some resources that can provide me better/more accurate info/estimations it would be greatly appreciated and likely useful to more people than just myself.

Well since no b2x to worry about anymore, I pointed my hashing power to Kano's pool. Should have a total of 4 S9s running before end of the year, it's not much in the grand scheme, but hopefully every little bit helps!

Question, what will this pool do if BCH becomes much more profitable to mine than BTC? Is merged mining or auto-switching between the most profitable an option or is this is a BTC only pool? Curious to know Kano's opinion and stance on this matter.

Are these #s a pretty accurate expectation? Obviously the last 3 months were pretty brutal luck-wise from the stats, but those are still strong payouts per TH/day. If luck comes back to "normal" then these payouts could be even better.

The 8 day ramp up causes me some concern, but I think I'm going to switch my miners over and go with Kano for the long-haul (after the fork, don't want to lose that extra free b2x waiting on the ramp-up would cost me), that payout per TH/day is crushing what I'm currently making and that's with "bad" luck!
