It was never actually hashing at that rate, it was incorrectly reported by bitmain's cgminer fork.  Did you ever compare the reported hash on your end to what the pool you were mining to saw?

Volt 800 and freq 250 typically results in the max. hash rate, though YMMV as almost every U3 responds differently.

Someone did study pools over a 12 week period and Kano.is was a top performer.  I would hazard a guess to say that the pool's performance has only increased since this study was done: https://bitcointalk.org/index.php?topic=1059040.msg11941177#msg11941177

It wouldn't make sense for them to dump all their hash online at once, that kind of shock to the difficulty would have a huge impact on their earnings, so it makes sense that they ramp it up slowly and not shock the network into large adjustments that affect everyone's bottom line.

It only has "value" if you already have a U3 and want to use it as a controller.  And in that case it has even more value if you order from CrazyGuy and get his custom firmware.

The command varies depending which mining client you are using, cg or bfg, but there are commands for both to set a lower starting difficulty.  It's cosmetic, though, and has 0 impact on your hashing.

It's not, that's just blockchain.info failing.  They are not the definitive source for all things transaction related.

I remember posting about 100G network difficulty a month or two ago and people responded like well that's crazy, we'll never get that high, way too much hash required, etc. etc. and now we are on the cusp of that number.  A few more big jumps and 100G it will be.

It's not so much the percentage change that is amazing, but the shear amount of hash being added.  It's like the entire network of only a year ago was re-added to the current network in one adjustment period and that's insane.

Thanks for running this again, Phil, it's a lot of fun.  I like and support the new rules, but I have a question about the above - did we have an issue with this either of the last 2 runs that made it a point to bold for this run?  I hope not, but just curious.  Maybe part of being in the club each month is that the user must post a picture of their stick with a handwritten note that says "sidehack compac pool Dec 11 - Jan 11" each time, only altering the date on the note.


I think you are supposed to have all your donation at one donation address, makes book keeping simpler.

Been answered many, many times.  You either rent out your hash somewhere that someone mines alt coins with, or you mine on a pool that mines alt coins.  You did not solve a bitcoin block if your best share is less than 79G.

For now it's a one shot deal, but who's to say we're not going to see more farms like this sprouting up?  It sure makes the life of a solo miner that much more difficult, the network difficulty has doubled since I started solo mining about a year ago.

Are you serious?  It's one 80mm fan, my desktop has 10 of them.  White noise is relaxing, you should learn to enjoy it!

Your sticks should be on one worker and donations on a second, not one worker for each stick.

Also, besides the driver mentioned, you should use integers for the clock setting in 5.4.1, not the hex value.

Old mines that have been shut off coming back online due to the >$400 price?  Warehouses full of S7s/(insert other high efficiency miner) going through burn in?  Whatever it is, it's growth that the network has never seen before, pretty amazing.

That's a great goal, not only for network health (if only every pool has such priorities), but also for preparation of the halving next year where tx fees will make up a much higher percentage of the total block solve reward.

Makes you wonder, if they are selling this many S7s how many are they keeping for themselves? 

I got a best stick share of 12.1M just after the last OC contest ended, I was impressed for a little stick!


Only ever had a >1G share with my S3, and only twice in the several months I've been mining.

These types of machines make sense to mine with even when the price is low, it's the older (less efficient) hardware that makes sense to use when the price is high.

Yea, those extra block found notices are kind of annoying.  I get several on my train ride in this morning and then when I get to a computer and log in and only see 1 solved I was let down.  I wish the app dev would fix it so it could tell the difference between a found block and a restart.  Also wish he would change the notification sound/icon for dead miners to be different than a found block.  He also still needs to add kano to the name, kano ckpool status, I think kano asked him to do that months ago when he first made the app...

I ordered my R1 from Crazyguy with his custom firmware loaded, he's a stand-up guy and I would recommend buying from him any day of the week (but use his site, not Amazon).
