Well I'd say that's very good. I'm going to ship it. Thanks for the feedback.

That is odd, but it does look significant. I guess you can't have extra hashrate without extra heat, but it does imply something funky going on internally if the hashrate changes depending on the diff the hardware is running at. Either way, keep running the faster firmware to confirm it remains reliable for days and I can push that firmware as official. Thanks for testing.

Right, just let it run with existing tuning.

And that's bullshit that dreamers always keep going on about just because they want another coin to make them rich by capitalising on first mover advantage again. Guess what, the first mover advantage is over. Bitcoin isn't going away.

Here, try this one:

It may be that increasing diff somehow leads to lowering of observable hashrate; this one won't change diff.

Are fans below 100% ?

IPV6 gives every person on earth quadrillions of their own IP addresses. You'd have to limit it to a subnet for IPV6...

Satoshi predicted it. He simply said people should be nice and hold off doing the inevitable... The rest of us predicted it too but there isn't actually anything we could do to "address" it as you have said. Bitcoin is a diffuse collaborative and there are no weapons to defend us against transient centralisation of power and hashrate. Proof of work will inevitably ALWAYS have some element of this happening at regular intervals. Changing the proof of work algorithm will NOT, as the article said, make any difference at all; a new asic arms race will simply replace the old one.

Probably the biggest mistake everyone makes is buying stuff off bitmain only to find themselves competing against bitmain... duh.

Yes it's a good article and it's accurate. What's frustrating for those of us that lived through the conversion of bitcoin from CPU to ASIC is that the rules and issues have never changed, and we see the same mistakes being made over and over by both new manufacturers and newcomers into the game trying to capitalise on a market they think they understand. Bitmain have got the mining world by the balls and that is not going to change by anyone trying to take them on by the same rules they play by. I've been warning people since the first ASICs got announced but alas no one listened, and then I just gave up trying to warn them... No one seemed to want to believe me and for whatever reason very few every considered consulting me despite my obvious position in the mining world.

Great, thanks for the feedback

I did not say it was your recommendation, I saw it was Halong's. Yours makes much more sense though...

That's an odd recommendation. The power rails are connected between the chains so you'd end up having two PSUs connected to the one rail; most PSUs don't like you doing that to them...

I pushed a more conservative firmware update this time with a slightly lower speed for balanced mode due to complaints of high power and fanspeeds from those entering summer, and more tightly controlled temperatures for optimal minimum fanspeed.

It should be version t1_20180512_024327 if you check for an update from the web interface.

1680W 92% efficiency (220+V). MyRig are the ones who sell them.

Thanks for the feedback. Will roll back and investigate.

For those keeping track of the latest firmware updates, I've pushed a slightly improved version which is designed to more reliably keep all chains up and running, and to fix a small timekeeping bug which sometimes showed the miners up for 100 days. The version number is t1_20180511_034450, just check for an update from the interface.

You did not get a payout. In the block summary you linked above your address is listed under "postponed", not under "payouts". It means you haven't accumulated enough shares to have gotten a payout with this block. However those shares are now added to your total for the next block in addition to your current running total. If you had gotten a payout you would have received it immediately when the block was found as payouts are mined directly to peoples' wallets.

Welcome back Genie. Your hashrate is definitely noticed. Hope you can stick around

If you're in a deferred position when a block is found, the HERP is added to the next round - and it can effectively double the herp by doing so. If you are in the top 100 with the added herp the next time around you're guaranteed to get paid. If not, you will be in the interleaved group.

All of this shows you are much better off sticking to the one address. You'll get paid more regularly and are more likely to get the full payout with each block find. Additionally it means other miners get a look in sooner so it is nice manners to do so.

Congrats. You'd never get a payout in many other pools with that hashrate. If you're in the payment section then you're due for a payout next block we find and then you'll go back into the postponed group till your turn comes around again.
