So - I've been under a rock for a while, but just realized that I have three L3+ units in storage.  At the time I stopped mining because they were worthless -- but now it seems they can make a profit.

Question is I see many options for firmware for these units.  One from the manufacturer to make it an L3++.  It supposedly saves electricity?

Any advice on legit firmwares for these units?  I upgraded to L3++ and I have not checked the power usage, but seems to work normally.

Thanks and I guess I am back into this hobby.  I've always used litecoinpool.org -- they same to pay the best (although it would be nice to receive DOGE coin paid out separately from LTC).

Curious what is up with SongCoin these days? 

Is Hash-to-Coins correct in that the network is mining at 1.3Th/s???  Someone is pounding it down to a pulp for some reason.

Or maybe an order on NiceHash went bad?  And they don't realize they are hashing that high?

I think that statement is completely ignorant and uncalled-for.

The owner of Hash-to-Coins is a very honest and reliable person (based on my experience over the last several years). 

He spends a lot of time on what I consider to be "the best Scrypt mining pool available" and does not charge any fees directly.

Keep up the good work!

Yeah not sure what is up with the pool.  It accepts your hash and even shows blocks that have been mined -- but not receiving any credit for my hash.  

Had to move my miners to NiceHash for now.

EDIT:  Everything is back up and working well!!

I'm a big fan of Nicehash -- but for some reason I had a small transaction sent among the batch -- instead of my typical larger transaction of .1 to .2 BTC.

I'd like to know what is going on? 

I see online over 8 BTC of transactions that have not been confirmed (at least the bunch I am a part of).  It has been almost 24 hours when writing this post.

Is there anyone official from NiceHash? 

Normally I would not go this route -- but I've found that just mining for Nicehash.com seems to pay much better than trying trying to mine individual coins. 

The Scrypt Altcoins seems to fluctuate very quickly with difficulty these days -- making them profitable for only a short period of time.  Even automatic multi-pools don't seem to be able to keep up with the difficulty swings anymore -- I guess due to so much hashing power out there now.

If you have a lot of time on your hands -- then definitely research individual coins to mine and sell them directly on the exchanges for BTC at the right times.  :-)

I'm not aware of any USB based Scrypt miner that is worth buying.  

If you have an Antminer L3+ (504 MH/s) right now -- you are in good shape.  

Mine is paying about .02 to .022 BTC every 24 hours.  Quite impressive @ about 760 watts.

The latest firmware on the L3+ has an option to shut the unit down if it hits 80 degrees C.  I believe you want to stay below that temperature if you want your unit to last.

80 degrees is not good.  The L3+ firmware has an option to automatically shut the unit down when it hits 80 degrees C.

Wow - unbelievable how much ignorance and stereotyping there is in the modern world.

My partner and I adopted two children at birth.  They both have turned out to be very impressive and beautiful human beings. 

If only heterosexual couples had to go through the same countless home-study interviews, drug tests and medical physicals just to prepare to have a child -- the world would certainly be a better place.

To mine Altcoins I use Hash-to-Coins -- as they don't try to convert the coins to BTC.  You do the trading yourself.

I have a Corsair AX1500i PSU for the unit.  It has 10 PCIe ports.  It is at maximum efficiency at about 750 watts / 115V.  Works like a charm -- but pricey.

LOL - lot of questions that you will find hard to have answered this early.

Are you looking for the cheapest or best quality PSU to run them?  120V or 220V?

Overclocking depends on how cool you can keep the unit.

Does your basement have cool air coming in and a way for hot air to leave?

$3500 is a deal right now.  Over priced for those that only mine LTC.  Otherwise price is about right.

Well it is all about temperatures.  I went from 384M to 387M -- noticed no temperature increase and my hash rate increased by about 4Mh/s on average.

I have really cold AC on the unit -- Output temperatures are no hotter than 59 degrees C on "Temp(Chip)."

Didn't notice an increase in HW errors -- although Chain #3 (5 HW) and #4 (22 HW) have always shown some over a 24 hour period.  Another person had similar findings in another post.

The unit is quite impressive and the fan can get pretty quiet if the airflow and temperature is right. 

I "rent" it on Nicehash when the price is at a certain level -- otherwise it defaults to a select alt coin pool where I mine a variety of alt coins.  lol

Back to the topic of the L3+ miner.

Anyone over clock their miner without issue?  Or please let me know if there is a thread regarding this option on the unit.

Mine uses 752 watts and provides 500 to 505 MH/s at the default setting 384M.  They have a range of 100M to 650M under the "Advanced Settings" option.

I agree with you there -- if it wasn't so noisy then I could put several of these around on some "free electricity" outlets.

LOL - I might as well add myself to the list -- have a handful of 88Mh/s A2s with PSUs built-in.  At this time will only consider local pickup in Portland, Oregon.

Wow - you are willing to spend $1800 + shipping + PSU for this unit?  How do you intend to make your ROI?

EEK - that market seems spooky.  It is still in "Beta" mode and accepts any coin.

So the A4 definitely has a new chip design?  And not a whole bunch of A2 chips combined together with a really powerful fan?

If the pricing would drop on this by 50% - I would certainly be interested in some units.  But the noise and temperature are concerning.

Did anyone get to measure the actually noise created by the machine?

And did I read somewhere that after 4 hours the unit got up to 60 degrees C?  Is that right?  Was that temperature based on the air coming out of the machine?  Or the actual temperature on the chip?

If it is air coming out of the machine -- how in the world would one keep your room cool?  If memory serves -- I believe my A2 units would average 33 to 38 degrees C -- depending how many units I had in the room and if I had some AC going.


EDIT:  I believe someone mentioned noise at 88db or so?  That is loud!
