westhash.com p=0.016
nicehash.com p=0.016 >>>>>> try p=0.0159
kano.is
f2pool.com
antpool.com
small correction see the slight price difference avoids choice confusion on the softwares part. acutally use westhash first if western hemisphere and nice hash first if europe , asia , africa ,australia Thanks. That's a good idea. Since WestHash is closer to me, here's how I've configured my pools now: westhash.com p=0.0159 nicehash.com p=0.016 kano.is f2pool.com antpool.com Looks like I'm all set. At least until the next difficulty change and I have to recompute the profit constant. Of course what we need now is some event to drive rentals through the roof, like what happened with Paycoin  yeah but sometimes people do all the hash at a top rate for ½ a day you will pick up on that every time now. Need help understand NiceHash/WestHash... I'm running 3 SP20's and here is how my first 3 pools are set up: stratum+tcp://stratum.westhash.com:3334#xnsub PW is p=0.0160 stratum+tcp://stratum.nicehash.com:3334#xnsub PW is p=0.0159 My 3rd pool is a P2Pool pool. My question is, I have 3 miners, all set the same for the first 2 pools, but this particular miner is picked up by nicehash once every day or 2, but when I look at the " Price BTC/TH/Day", the highest price is 0.0137. So why is my 0.0159 getting picked up? And why not my other 2 miners with the exact same parameters? I'm so confused!!!  |

Like I said, it's ultimately a matter of how one justifies it. We can debate to eternity and still would not be able to come up with a definitive conclusion that we could both agree on as there are a variety of factors that are difficult if not impossible to accurately and consistently quantify. In other words, it is a very relative and subjective topic. At least, I attempted to have some sort of controlled comparison by isolating complicating factors to the best of my ability/knowledge and providing numbers/computation. That's all we can do in this matter. If you're happy with the justification of your PSU choice and I'm happy with mine, that should be good enough. Detailed PSU 80 Plus certification results here: http://www.plugloadsolutions.com/80PlusPowerSupplies.aspx#I'm not at all disagreeing with your method, just that your numbers don't match with my experience in terms of the average price difference. It's not a matter of justifying my choices at all, I don't actually use ATX PSUs at all for mining, other than for some testing. I don't need the minor rails so I generally just buy server PSUs. It's hard to beat the value of a 2450W Platinum PSU for $50.  Is there an interface board available for the 2450W PSU? I have a Delta DPS-2000BB with a Gekko Science breakout board, but I like the idea of a Platinum PSU. If there isn't a interface board available, would you mind sharing how you wired yours? |

When I tried to follow the directions below to update my S4, when I enter "chmod +x cgminer" I get "chmod: cgminer: No such file or directory.
What do I need to do to correct this so I can finish with the update?
Thanks in advance for all the help!
Did wget succeed? Try doing wget line again and make sure it downloads the file. Check where you are and what files you have: pwd ls -al

Thank you so much for the time you've invested to make the S4 more funtional, ckolivas. I'm going to send you a donation tomorrow morning.
I'd like to try ck's new version tomorrow, but I have no idea how to go about updating cgminer. Can anyone shed some light, or point me towards a guide?
Assuming your S4's IP address was say 192.168.1.99: ssh -l root 192.168.1.99 (or equivalent with putty)
wget http://ck.kolivas.org/apps/cgminer/antminer/s4/4.6.1-141018/cgminer
mv /usr/bin/cgminer /usr/bin/cgminer.bak
chmod +x cgminer
mv cgminer /usr/bin/cgminer
/etc/init.d/cgminer.sh restart
I think that might not keep across a power cycle though. I did this, turned the power off, turned it back on, and I have noticed that the web gui has become quite slow? previously when navigating through it, it was quite fast on loading pages, etc Also, after ssh the above, after reboot, in terminal it shows; PARAMS = --bitmain-dev /dev/bitmain-asic --bitmain-options 115200:32:8:7:200:0782:0725 --bitmain-checkn2diff --bitmain-hwerror --queue 8192 Is that anything important? Thank you for your help ck.

hello everybody,
I've paid for 2 s4 batch 1 that received last friday. Both of them were working ok with default parameters (not overclocked yet) until yesterday night that one of them was powered down and now I'm not able to power on it again. I've tried unplug the wire, changing the wires between them, but the result continue to be that this machine doesn't work.
Any suggestion please?
Thanks in advance.
I had a power unit go down last weekend. Contact Yoshi at Yoshi@bitmaintech.com, or call. They are working out of Denver: Bitmain Warranty 3700 Quebec St. #100239 Denver, Colorado 80207 Tel: 844-248-6246 They will help you get your unit fixed. |

This always happens when a company opens cloud mining. Their prices need to raise to make the cloud mining look like a better deal. Still, with the current price of BTC, the S3+ is cheaper if you consider the cost in fiat. There are much better deals currently available: Rockminer and ASICMiner Prisma are two. I use the following spreadsheet to compare apples to apples. I hesitate to share because well, people will freak out because it is not completely accurate in its forecast, but it does use an industry scaling factor, which will probably be overrun unless BTC goes up. I will probably adjust the scaling factor for myself. You need to understand excel to use it, but essentially, when I go in, I update the difficulty, day and price, unless your electricity rate matches mine, you'd also want to update electricity $/kwh. I then click on the name of each miner, and it takes me to their website where I double check the price. If the principle cost is fiat, I list that bolded, if BTC, I list that bolded. I also use a calculation for the s&h if in BTC. The last three columns are where I compare apples to apples. The notes explain much of what I was thinking when I programmed it the way I did. You'd want to update costs for PSU and other. I have my preferred units that are essentially priced here. http://www.hundredpalms.com/profitability_comparison.xlsxDan On your Excel spreadsheet you show Rockminer R3 Box (4) having a total hash rate of 2.7 THs (or 675 GHs per unit), but Rockminer's site shows their hash rate to be 450 - 480 GHs each. Multiply this by 4 and you get 1,800 - 1920 GHs, or 1.8 - 1.92 THs. Do these actually Overclock up to 2.7 THs? That would be a 40% hashing power increase over stock (480 GHs). Secondly, you show the Rockminers as being overclocked at the astounding rate of 2.7 THs, yet the other miners are shown stock. This isn't Apples to Apples. Your work looks great, I'm just not sure it's completely accurate or unbiased. |

Like someone else previously said, if you're worried about customs with large orders, just order 5 sets of 2. If 1 or 2 get questioned, the others will still be delivered. This wasn't my idea, but it sounds logical.

The only issue with ordering directly from Bitmain is that they don't take PayPal, only Bec and I don't have any since I am new to this. Plus PayPal is very easy to use.
When I need Btc, I just go here and find some to buy: https://localbitcoins.com/I find paying a little extra for the Btc is cheaper than buying form someone with Paypal. Check it out for your self and see which way would work best for you. |

Anyone running vertminer 0.5.3 on BAMT? I got the latest version from GitHub and installed it with these instructions: https://bitcointalk.org/index.php?topic=404364.msg4668635#msg4668635It works, but seems I can't change GPU settings. Not from thecgminer.conf, not from the command line, not from the vertminer. Also, I can't see the card temps at all. The web monitor shows the temps just fine though on http://myip/cgi-bin/status.plEven the ./vertminer --help shows only these gpu options, so I suppose the rest are actually missing? --disable-gpu|-G Disable GPU mining even if suitable devices exist --gpu-dyninterval <arg> Set the refresh interval in ms for GPUs using dynamic intensity (default: 7) --gpu-platform <arg> Select OpenCL platform ID to use for GPU mining (default: -1) --gpu-threads|-g <arg> Number of threads per GPU (1 - 10) (default: -1) --lookup-gap <arg> Set GPU lookup gap for scrypt mining, comma separated --intensity|-I <arg> Intensity of GPU scanning (d or -10 -> 21,default: d to maintain desktop interactivity) The only way to change core/mem is to set new defaults in gpu bios and flash the card with that. Which is a bit annoying when searching for the best values..  Had this same problem two different times (two weeks apart so I forgot the solution) - be sure to run ./buildit.sh and NOT sudo ./buildit.sh. running as superuser seems to break the Open-GL / ADL stuff from what I can tell (assuming you copied the ADL_SDK .h files into the appropriate folder?) I managed to make it myself. If you want to build it on BAMT it's quite easy: 1 - Open Root Terminal (or Run LXTERMINAL) 2 - Type: cd ~/Downloads/ *(if this folder does not exist, "type: mkdir ~/Downloads/" then type cd ~/Downloads/) 3 - Type: git clone https://github.com/Bufius/vertminer-gpu 4 - Wait for it to clone the GIT for vertminer 5 - Type: cp /opt/miners/cgminer/ADL_SDK/* ~/Downloads/vertminer-gpu/ADL_SDK/ 6 - Type: cd vertminer-gpu 7 - Type: ./buildit.sh You've succesfully built/compiled vertminer-gpu and now you need to set up a .sh (shell) that starts vertminer with your config of choice. 1 - Still in the Terminal window, Type: cd /home/user/Desktop 2 - Now type: nano start.sh and enter the following code: export DISPLAY=:0
export GPU_USE_SYNC_OBJECTS=1
export GPU_MAX_ALLOC_PERCENT=100 #if you mine with 280x or 7970, set this to 200
export CGMINER_BIN=/root/Downloads/vertminer-gpu/vertminer
$CGMINER_BIN --scrypt-vert \
--config "/home/user/Desktop/config.conf \
3 - press CTRL + O (Write Out to file) - Save it as start.sh - then press CTRL + X 4 - Type: chmod +x start.sh 5 - Now type: nano config.conf and enter the following code: {
"pools" : [
{
"url" : "stratum+tcp://yourpool.org:3333",
"user" : "yourusername",
"pass" : "yourpassword"
},
],
"auto-fan" : true,
"auto-gpu" : false,
"temp-cutoff" : "95",
"temp-overheat" : "85",
"temp-target" : "80",
"gpu-fan" : "0-100",
"intensity" : "SET PREFERRED INTENSITY",
"vectors" : "1",
"worksize" : "256",
"lookup-gap" : "2",
"thread-concurrency" : "SET YOUR TC HERE",
"api-port" : "4028",
"expiry" : "60",
"gpu-dyninterval" : "7",
"gpu-platform" : "0",
"gpu-threads" : "SET YOUR THREADS HERE",
"gpu-engine" : "SET YOUR CLOCK HERE",
"gpu-memclock" : "SET YOUR CLOCK HERE",
"gpu-powertune" : "20",
"log" : "5",
"no-pool-disable" : true,
"no-submit-stale" : true,
"queue" : "9",
"scan-time" : "30",
"scrypt" : true,
"kernel-path" : "/usr/local/bin"
6 - CTRL + O and save it as config.conf - then press CTRL + X 7 - Type: screen and hit space 8 - Type: ./start.sh and this will launch vertminer-gpu with your config, and voila! If you ever need to edit your config, open it with leafpad or edit with nano (i.e: nano /home/user/Desktop/config.conf) Need help? Ask me. Want to throw some VTC to me?

What do I need to do to corrrect this so I can start mining?
Thanks!

Thanks for the reply. I've been to that link also. I guess I will just keep scratching my head and see what I can come up with.

When I try to make the Address Assignment FIXED, it comes back with ERROR. No other explanations. Also, my Cube shows no activity.    The only difference with my setup and yours is my computer is at 104 instead of 111. Thanks for you help! John |

I've been trying to reconfig the 2Wire Uverse router like you show, but each time I get this message:
Errors
The manually configured DHCP range is not within the specified subnet or you have entered an invalid DHCP Lease time.
I copied your example verbatim 3 different times but always got the same message. And the Lease Time stayed at 24 hours.
Any ideas?
Thanks
I would have included a screen shot, but I'm still still trying to figure that out.
