I do have another controller - I'll try swapping that out now. Can't hurt.

That did not work..

After it "shutdowns" (fan at full speed for 30 seconds) the fan is still running, but barely??

Sounds a lot like what happens when using wrong controller software. Canaan does have a 841 version of software along with 821 version.

Is the controller using 841 software or 821?
What does the advanced GUI report?
Does it see the AUC and if so, does it also see the miner?

[bit2255]

Sounds like I need to update the controller software to run the 821.

It is recognized by both CGI status and also Awesome Miner - It shows a good connection, but not hashing.

It has yet to be picked up by Kano Pool Worker page.

I'll work on updating the software. I guess I just need to pop out the card and load the new controller software - I hope its that easy.

Thanks

[NotFuzzyWarm]

Ah ja, misread and thought you were trying 841 on 821 system.
Most definitely cannot use 721/741 software with the A8's. Tried that and not even the AUC was seen. Flashed a controller to A821 and works perfect. I have *not* tried running a8's and 7's together on 1 controller and for a couple reasons don't recommend even trying since rasPi's are cheap.

To reflash the controller, I just need to pop out the sd card and update with the 821 software.

One question - when I popped the card into my drive , it said I must reformat it 1st - I can't open it to see what is on it now (i wanted to check that so I replace the same files..... (I'm not well versed with re flashing ...

I will NOT buy current hardware from anyone unless I can grab a firesale price. ( 2-3 months payback on hardware cost at today's profitability ) Why?

I have not an inkling of doubt that Bitmain is on the verge of a 10NM release in ASIC. Probably July or August.

I think this because;


a) Bitmain is wholesaling every different kind of unit in 16NM Technology from every nook and cranny of their warehouses. ( 13th S9's??? Really? T-9's Really??)

b) Bitmain just issued huge numbers of "coupons" to entice buyers to clear out their inventory. Coincedenatlly, those "coupons" expire in June 2018.

c) Bitmain "wanna be competitors" are chomping at the bit to grab Bitmain market share. We all know how Bitmain feels about that!! No way They are gonna get beat on "first to market" on 10NM.

d) Greedy resellers piled on huge orders of S9's and L3+'s at the highs of the market in hopes of getting rich quick. Most thsoe units never sold to "suckers" (check the hardware forum" You can't throw a dead cat in there without hitting an S9 or L3+ ad.)


     In 3-4 months you'll be able to buy ANY 16nm ASIC for pennies on the dollar. Wait for it.

You might argue that Bitmain pricing right now (vs say just a couple months ago, Dec / Jan ) is close to fire sale price.

I mean, if you are right about new miners coming out later this year, what will the hardware pricepoint be?  My guess is they certainly won't be near the ROI of 2-3 months that we saw at the end of last year (not without help from the price of bitcoin increasing, or direct competition in the 10nm space).

Flashing will replace everything on the card anyway.

Does anyone split mining, say between a pool like Kano's and a PPS pool?  Just curious, I know the logic might say point all your power here and split the rewards, but is there security in splitting your guaranteed earnings with the benefit of splitting found blocks?  

Probably depends on if the pool shares transaction fees,  or the cost of fees you pay to that pool, or orphans, or a number of other variables.... just curious (Oh, I swear I searched this ,so don't get mad if this has been discussed before.)

Thought I would share this experience. I've been away from Kano for about four weeks, but it was by design.

Back when I thought the US govt was going to shut down (I had a very bad experience resulting from an earlier one), I emptied my Core for cash so I could pay my rent if my VA disability or SSA got bolloxed. But then, I had to pay my quarterly hosting charges...in BTC...soon. We were not doing all that well here at Kano at the time.

The solution (for me, at that point in time) was to move to Slush for only enough time to get that quarterly billing back in BTC reserve, which I did.

I'm back at Kano now, Whilst I was commiserating with Alan on the Ice Planet to get the assignments changed, he pointed out (chuckling at the time, methinks) the foibles of pool hopping...but then acknowledging that sometimes the situation demands what some would call an odd tactic. In this case, at least, it worked...for me.

I also ran numbers for the past month re both pools just to make myself feel better that it was indeed the correct choice to return...and if I had been at Kano for those four weeks, I would have earned .096 BTC...but it would have come too late to pay my obligation. I earned .077 at Slush for the same period. The result was what I expected, but nonetheless made me feel better.

So...this is the best place to be, IMHO. Always has been. When I left solo mining years ago for Slush, that was about the only choice I had. Kano started his pool, and I went with it.

As we say in Team Rubicon...you cross your personal river Rubicon...and then you burn the boat.

Mine on.

I'm getting as high as 0.819% on my 721s...they always stay that high but it never seems to affect shares earned.

[gaud]

a number of companies are chaceing the 7nm chip for various uses the competition for bitman is about to hit a new level when larger more diversified companies start chomping at the bit like hitachie.

Do you have each 721 on a separate raspberri pi or are they all combined as one?   That adds up the errors.  Right now my two 821's combine for a .20% error rate while the s9's range from .12-.168%   So in theory, the 821's are less by themselves.

That's a relief. I also get around .8% when I run at zero power setting and .75% at -1 power setting. Thanks

Pricing is relative. At today's "fire sale pricing" it will take you 10-12 months to recoup your investment. Not my idea of "fire sale pricing".

I have them combined so they do accumulate errors.  I don't pay attention to the error rates anyway as it has no affect on shares earned.
