21  Bitcoin / Hardware / KNC Neptune Controller Board Problem on: March 30, 2015, 05:45:36 PM
So I've had a 6 cube Neptune running for the past week without issues.  About 2 hours ago, it quit mining and the gui shows no cubes.  I've tried restarts, plug/unplug but no help.  This is currently the second board I have with this issue.  What's the issue?  I know I must be missing something.  Does the firmware just get corrupted and needs a recovery SD?

Is $8500 a good deal for both the buyer and seller?


10-Plat 1000w Server PSU w/ breakout boards and pci-e cables.

Should it be more? Less?
23  Economy / Computer hardware / Price Check on Neptune Cubes on: March 23, 2015, 12:46:49 AM
I just purchased 3 Neptunes and got what I think is a decent deal.  Out of the 15 cubes, there are probably 4 or 5 that a couple of dies will drop power after a bit.  Is there any value to these cubes on a resale market since not all dies appear to work?
24  Bitcoin / Hardware / GAW Miners on: March 20, 2015, 08:34:17 PM
I don't know anything about them, but at they are auctioning off some stuff in Atlanta that includes some GAW miners.

I tried to look up from the pics and these may be alt-coin miners.  If so, please move to appropriate area.  Thanks.
25  Bitcoin / Mining speculation / Ok, I shouldn't have but I did. Was it a very big mistake? Neptune on: March 14, 2015, 11:39:39 PM
Ok, I was able to pick up a couple of the 'new' bonus Neptunes for less than $.22/gh.  Besides being fire starters, 'scam' company, etc, what's the problem with these that I was able to get them so cheap?

26  Bitcoin / Hardware / SP20 Help!!!! CGMiner won't start!!! on: December 31, 2014, 10:11:25 PM
Just like the title.  I've tried factory reset, re entering the pool info, etc. No go.  Would like to have this running before I head out tonight. Sad
27  Bitcoin / Hardware / S5 Review--Purchased on: December 30, 2014, 05:26:31 PM
UPDATE:  After a few hours of mining, I couldn't resist playing. I decided to crank open a window and let some winter air in and up the settings to 400M.  After 13min, here's what I was looking at:

Here's where I'm at with the 400 setting after 13min. Temp has been holding steady, but unit is in a room with the window partially open and 24F outside. Don't want to push further today as I am getting ready to leave the office.

Elapsed   GH/S(5s)   GH/S(avg)   
                1,490.62    1,368.15

Hardware errors are running about .025%  I don't have a watts meter to tell how much it's pulling, but I really am impressed with the idea it can go much higher than it being marketed as 1,155gh.  +1 to Bitman for the marketing and over delivering on hashing speed.  I can honestly say now that I am happy with the machine even though it is too loud.  More tomorrow when I check it against an SP20.

Original Post
Ok, this is my first review of the S5.

1. First Impression:  Lighter than other units when unpacking from box.  Good packaging.

2. DHCP worked without a hitch.

Chain#   ASIC#   Frequency   Temp   ASIC status
oooooo oooooooo oooooooo oooooooo
oooooo oooooooo oooooooo oooooooo

Not real happy seeing only 6 chips on first row of each blade at start up.

Here's after 5 Minutes:

Chain#   ASIC#   Frequency   Temp   ASIC status
xxxxxx xxxxxxxx xxxxxxxx xxxxxxxo
oooooo oooooooo oooooooo oooooooo

Even less happy.  Stopping now to set up my second unit.  I'll keep updating, but so far not thrilled.  This is a single rail 1000w psu.  I'm going to set the second unit up using two CX500 psus.

Second unit setup was just as simple, but with no hashing issues at stock.  It was noted though that both units show the first sequence of chips on both boards as being only 6 instead of the normal eight. After counting, these are 60 chip boards.

After 5 minutes with the second unit, it is averaging 1158gh/s with temps of 47 & 48.  Well within specs.  Now off to see if any work can fix the first unit. Be back soon.

A nice reboot seemed to fix the chip issues with the first S5 unit.  After 5 minutes, it seems to be right in line with the second unit.

So now after having both units up and running, I'll leave them at stock for a bit and report back as to what CKPool is showing for stats.  In the meantime, a couple more observations:

First, as others have pointed out, the sides are a flimsy plastic and there will be no stacking of these units.  Second, the noise level is somewhat disappointing.  You won't want to be in the same room as these.  And it goes without saying, these put out a lot of heat.

So overall, my first introduction to the S5 is average.  No real highs or lows.  If you want something to just plug in, set and forget, it appears to do a good job. My SP20 units arrive tomorrow, so I'll compare the two and be able to give an opinion as to which I prefer.  After some of the other reviews, I'd say that neither unit is really a true 'home' miner.
28  Bitcoin / Hardware / Non-Hashing Module in Dragon 1T on: December 15, 2014, 09:58:29 PM
I've got a module in my 4 module Dragon that the leds do a quick flash when you turn it on, but they don't light up green when it initializes or starts.  I've swapped with other modules and they still work with the connectors.  Any other ideas?

Is there a distributor here in the states?  While the price with coupons is decent, the shipping makes it a no sale. YMMV, but the shipping doesn't work for me on the S3+, C1 or the S4.

If you are planning on letting your S4 coupon expire, I could use 2. UserID the same as forum name. Thanks.!
32  Bitcoin / Pools / Just a quick question about Eligius on: October 17, 2014, 11:19:56 PM
Does Lukejr have anything to do with the pool?  I read that he did at one time, but doesn't anymore.  Is that correct?
33  Bitcoin / Pools / Shares and Pool Diff on: October 10, 2014, 11:58:21 PM
Just curious if there is a way to set up a pool so that you are credited for share difficulty you find and not just the current share diff. Example:  if diff was set at 1024 and you found a share at 4096 diff, you would get 4096 shares instead of just the 1024.

Maybe statistically it doesn't make any difference, but small miners that solve a really high diff share might see a better reward.

Any ideas on this?
34  Economy / Digital goods / $200 S4 Coupon for .35btc on: September 26, 2014, 11:17:28 PM
If you are going to be buying one of the S4 units, here's a $200 coupon I can transfer to you.  I'd rather have the btc now than using it to purchase one of the current S4 units.
35  Economy / Computer hardware / SOLD----WTS (10) AntMiner S3 .65Each Shipped USA Only on: September 08, 2014, 01:30:34 PM
I've got 10 S3 units for sale. I am not including the ones I have from batch one as they don't perform up to specs like they should.  You can see them hashing at

I ship from central Missouri.  These do not come with PSU.  While I've never used escrow, it's fine if buyer pays the fees.

I get PM notifications in my email, so will see them quickest.  I also have 2 listed on my website:

Price .65btc each.
36  Economy / Service Discussion / Take a look at the site and let me know what you think on: August 10, 2014, 07:14:23 PM
I've set up a website, pretty generic to sell miners.  Right now I just wanted feedback before I add items and such.

If you know of problems with wordpress or security issues please let me know.

37  Economy / Computer hardware / SOLD----WTS Lketc Dragon 1T $1,375 or 2.1btc on: July 23, 2014, 04:46:19 PM
I've got 4 1 of the second generation Dragons without the lcd screen and 1 with lcd.  All working great.  No overclocking, etc.  They've been in the server room at work and now need a new home.

I know this will limit my market, but local pickup and exchange (Columbia, MO) only.  I'm not quite trusting of shipping these.  I do have the original boxes though.  PM me if interested.  You can post here, but I may not see it as quickly.

38  Bitcoin / Mining software (miners) / Solo Mining BFGMiner, Various standalones & bitcoin-qt/bitcoind on: July 21, 2014, 12:58:19 AM
I've changed the topic for my followup question.  In a nutshell, I'm wanting to know if bfgminer will allow s3 & A1 units to connect to it with bfgminer being the instance that connects to bitcoind client.  And if so, by using the --coinbase-addr, can each one have a different payout address rather than a solved block reward going to the bitcoin-qt wallet?


So I was re-reading the readme file about solo mining:


BFGMiner supports solo mining with any GBT-compatible bitcoin node (such as
bitcoind). To use this mode, you need to specify the URL of your bitcoind node
using the usual pool options (--url, --userpass, etc), and the --coinbase-addr
option to specify the Bitcoin address you wish to receive the block rewards
mined. If you are solo mining with more than one instance of BFGMiner (or any
other software) per payout address, you must also specify data using the
--coinbase-sig option to ensure each miner is working on unique work. Note
that this data will be publicly seen if your miner finds a block using any
GBT-enabled pool, even when not solo mining (such as failover)"

So does this mean that if I use the --coinbase-addr option that the block reward will go to that address rather than my bitcoin-qt wallet address?  Is that a possible solution to multiple people solo mining with bfgminer connecting to a bfgminer as a proxy pointed to the bitcoind client?

What happens if bfgminer is pointed to the bitcoind without the --coinbase-addr and a block is found?

If these are stupid questions, I'll apologize in advance!
