Antminer U3 owners rejoice - bfgminer/mac support incoming. I don't own one, so feedback on testing of this beta version with support would be doing me (and all the actual U3 owners) a real solid!

Also, given that USB miners are increasingly uncommon, would there be any demand for a Mac IP miner monitoring app? The API Output window was added as an afterthought to MacMiner and wasn't implemented perfectly, so if people want it I'm considering writing an app dedicated to monitoring your miners from your Mac, and sending the output to MobileMiner http://mobileminerapp.com

Props to Nate (nwoolls) for making such a project possible

the stock speed is 1.6 and claims overclocked it can reach 2.2 - though bfgminer seems to run faster than stock by default - so that much is normal.

WRT accepted/rejected shares, how long has it been mining and what pool are you connected to? Minimum share difficulty on ALL pools now means it takes quite a long time to even get your first accepted.

I use eligius.st and for laziness I'll repost a section of my response to another user with a similar question at http://fabulouspanda.co.uk/forum/ :


My advice is to find the pool with the lowest payout threshold and lowest share difficulty - If you find one that suits you I'd appreciate a recommendation as I'm getting asked this more often with the sky high difficulty!

I've set up an account with the pool and I'll test it with the Jalapeño to see how it does at 7GH (somehow misplaced the antminer in the last week…) - after 7 minutes I got 1 accepted share, but since finding that once I've found 8 more in just a few minutes, so it could be that the first share is 'default' difficulty and it adjusts down based on how long it takes you to find that. It definitely does support auto difficulty adjustment.

when you say off and on, what's the longest time you've left it running for? every time you restart it the work starts over…

The pool help page says "Please note that we only support ASIC miners and do not support CPU or GPU mining." which suggests like most/all pools if you're not hashing fast enough you're not going to have much if any success…

That said, it does seem as though you found the best pool for slow mining, if this is anything to go by:

https://bitcoinsfaq.wordpress.com/2014/12/17/bitcoin-mining-howto-best-paying-pool/

(about 1/4 down the page, and your pool called bitcoin affiliate network rather than bitcoindigger)

Looks like Ill have to do some more buying... once i get the jist of this ofcouse... So with slow miners, i.e. under 500 Gh/s what pools would you guys recommend for best profit.... yeah i know the golden question... the pot o gold at the end of the rainbow... the... you get the.. jist.

Awesome, such a shame specs are moving on so fast to make all our original miners redundant!

You can use your Rockminer RBox with Macminer really easily, the most basic method would be adding

-S rkm:all --set rkm:clock=290

to the ASIC window flags - I believe the default frequency is 270 so varying too far from that figure will stop it mining, at the very least efficiently

So i just imputed that information and was given this.  [2015-03-21 23:29:40]Applications/MacMiner.app/Contents/Resources/bfgminer/bin/bfgminer: --set: unrecognized option                   

Ok, total ignorance here.. is that located under FPGA/ASIC Miner Options Devices Manual Flags: ? ifso I have this pasted: with nothing else.-S rkm:all --set rkm:clock=290

Hmm... yeah that is how i have it set up. I am out of state for work. I will be back on Thursday. I will definitely give it a try then.

Nice! The issue with the hash speed not displaying is due to changes in bfgminer since the last 10.6 version was released. Is it showing up in the API Output window?

If you don't mind getting hands on, the two branches are here:

https://github.com/fabulouspanda/MacMiner/branches

The relevant code is inMacMiner/asicMiner.m in each branch that parses the bfgminer output so you could copy the code from the master branch to your clone of the 10.6 support branch

I don't have time to work on it any time soon unfortunately!
