Hmm, that sucks. I usually don't have to pay fees when receiving stuff with USPS and the item is declared as below $100. If you can check with USPS as a last resort option that would be great, otherwise $47 is not worth it I'm afraid  Ben oui, 23$ de douanes/frais pour 20$ déclaré comme des CPU boards ... Belle marde |

Can you give me a rough estimate as to how much it would cost to ship to Toronto, Canada?
shipping is a bummer: ~$47 UPS to Canada. Also UPS will make you pay stupid custom fees. I pay like 23$ for a 20$ declaration (7$ of fees) |

So how can i add more of those frequencies?
The other thread didn't give any guidelines
Which firmware version do you have ? You should update it to the October one. that's my guess I tried both October f/w. But gonna try once more when i get home. Never had a permission denied on that file. |

I haven't found the bug with the NMC sound. Haven't had much time to look though.
And yeah, unfortunately NMC is 25 new coins per block now. Much less income from merged mining now.
Thanks you Doc, no rush for the NMC bug. I was just "OMFG we found it !!! hooo not  " I hope we see the NMC value going up a bit. |
|
|

Why people are dumping hashrate when we are hitting a long block. I don't understand the thinking. Running after luck ? EDIT: Doc, we also still have the machine slot sound for NMC if you tried to change that EDIT 2 : NMC just hit his halving mark. The reward if now 25 NMC per block. |

I tried many voltage (0.7 - 0.725 - 0.75 - 0.8 - 0.825) with different frequency and I'm getting good result for like 6 hours one machine and like 8-12 hours and two others, after that it's falling off.
I can't make them stable on the long run. They need restart.

Bring about 0.7TH/s online before the end of the year. Pulling my BFL 50 (thankfully I don't pay for electricity for this thing).
I'm running one at home  It will be unplug this week also. My first miner will be replace with an AntFurnace (modded S1 boards) |

I am trying to get 2 S1 blades to work; so far, I can only get 1 blade to hash. If I plug in both USB UART sticks (cp2102), only 1 works, never 2. My cgminer running config is:
cgminer.exe --bmsc-options 115200:25 --hotplug 0 -o mypool:3333 -u myworker - p xxx
I am getting about 50 Ghs.
Both S1 blades are pencil modded for undervolting.
I'd like to get both blades to hash. BTW, the cp2102 USB sticks go in Pluggable USB Hub bought on Amazon. I am running the pre-compiled cgminer (cgminer-bmsc) found on the thread here. Zadig winusb driver installed for both 2102 sticks, running Windows 7 64-bit.
Any ideas?
yeah remove the hotplug parameter, let it discover both blades then restart with the hotplug. |

However, nothing lasted more than an hour at ambient temperatures of 17 degrees C.
1 hour is nowhere near enought to come to such a conclusion, unless ofcourse the rate is way off, in which case, evn 10 mins would do. I let them run for over 10 hours, One of mine went down to 400 GH/s and the other to 420GH. So on the long run, mines are not performing well. My good machine was still doing fine but loosing speed to0 ... about 515gh in almost 24 hours. 10 hrs is a good enough indicator I'd think. On the positive side, if these are the same units that could not go over 450 in the first place, but can now hash for a while over 500, then you probably have to revert to restarting them often like you were previously, at least now they'll be running faster. On that note, you may find that simply restarting cgminer will "clear things up". Yeah, I wish i had some kind of auto-reboot triggered on a timer. How do you retstart cgminer quickly without rebooting and changing the freq ? |

The bottom line is Quite happy that i'm saving power. If you have a unit that you can OC to 250 with the default setting, you can make a huge power saving and even pushing it harder and getting awesome result.
If anyone has found a trick with the units that is somehow under performing with the stock setting, share it with us so we can make them more profitable.
It is false to say that you are making a power saving, rather, that you can achieve the same rate with a PSU that can efficiently supply the wattage at the datasheet voltage (plus a bit more for the fans and lost power). Thus if you are running with a voltage setting of 0750 and freq of 250, you can run the rig using a PSU with a rated wattage of ~400 watts and achieve at least 504 Gh/s, or a voltage setting of 0720 with a freq of 225, a PSU rated at ~350watts to achieve 453Gh/s. Of course, for running them that tight, they'll also have to be at least bronze rated too. If, however, you are running a PSU rated at 650watts, you'll not see the drop at the wall as you expect. I see, i run two on a Corsair 1000 Gold and one Corsair 750 Bronze. I was sure the lower voltage would drain less power. My bad i guess. |

I have concluded that with the stock heatsinks and paste, that increasing the voltage on my six S3+ units does not work for me. I tried everything, and got some clear short term performance improvements. However, nothing lasted more than an hour at ambient temperatures of 17 degrees C. Finally reflashed to the 10/24 firmware and went with frequencies of: 225, 225, 237, 237, 237, 243. Increasing frequencies above those six points results in dropping hashrates, with or without corresponding voltage changes. I assume the successful overclocking by others is either different chips or better cooling. It was frustrating to see clear jumps above 500 GH/s, but then rates that dropped below stock of 453 GH/s.
I came to the same conclusion as well. I got the one unit that was running steady at 504 GH/s before and now running 529 gh/s with a voltage of 0.75v. Which is impressive since it's taking less power and i have been able to push it a bit more. For the unit that I had trouble with. Playing with the voltage doesn't help much in the long term. One of the two is running 231.25 with a voltage of 0.725 and it's getting 450 gh/s. It's not bad since the voltage is lower. it's more efficient but not performing as like it should at this frequency. The other one (From Batch 1) is a pain in the ***. Whatever I tried is just go down and down on the long term. getting 444 gh/s at 231.25 with 0.725v. Still saving power but under performing as well. B? 0d 5h 11m 32s 451.51 450.39 0 0.0159% 231.25 B1 0d 10h 33m 42s 530.09 529.58 0 0.0004% 45 44 262.5 B1 0d 6h 39m 32s 458.03 444.47 0 0.0002% 231.25 The bottom line is Quite happy that i'm saving power.

Second B1 Unit (one that wasn't working good) has been going down after one hour. Will try 250 freq now.
EDIT: Both now are going down. Will lower the freq further to 237.5
EDIT: Trying 225 with 0.72V. 237.5 wasn't working

This thread is F******** EPIC.
Now i have two units that had trouble running at stock ... running at least at 250 with lower voltage.
One of them is at 262.5 running at 524gh at the moment. I couldn't even make it run at 441 at 218.75 back then.
Thanks you so much for this !
You are welcome, mind though that the pleasure, like custom dictates, is all mine! PS. Would be nice if you explained how and why you had to update the firmware of your S3 for other users ..... With pleasure ! First, i have 3 S3, Two Batch 1 which one was OC to 250 and one had trouble even running at 441 at stock clock (218.75). Then I bought a used one like a week ago or so. This one had also trouble to be stable at default clock (218.75). After finding this thread. I was edit my CGMiner.lua file in the /usr/lib/lua/luci/model/cbi/cgminer (writing this path by memory) and tweaking the voltage to 750 (0.75v) for the 250 Freq and 725 (0.725v) for the 225 Freq. By doing that, I had horrible result. Follwing Pekatete advice, I upgraded one of my problematic miner to the Firmware antMiner_S320141024.bin and give it a try (DO NOT USE THE NOVEMBER ONE). So I set my Batch 1 problematic unit to 250 Freq / 750 (0.75v) Boom was stable and had no HW / problem with any chip. I could have never done that before. Setting to 225 would have gave horrible result and bad chip status (the famous X on the miner status). Seeing those unbelievable result. I upgraded all my miner to the October 24 firmware. Set my both Batch one to 262.5 Freq (0.75v) and my third S3 to 250 freq (0.75v). The last one looks like less performing at the moment but they all been running since short time. So let's see and wait for now. Still, at the moment. UPTIME 5s AVG AVG HW FREQ Nbr. fail chip S3 B? 0d 0h 40m 30s 516.39 495.85 0% 250 0X S3 B1 0d 0h 26m 40s 548.47 527.99 0.0005% 262.5 0X <==== OC to 250 with the previous default setting by bitmaintech S3 B1 0d 0h 24m 46s 546.16 518.37 0.0033% 262.5 0X |

For me, it's faster from him then anything I order from China/Hong Kong.
Like 10 days. My package made it in 7 days in Canada. Add a day or two to get it home.

tried that => cgminer.exe --bmsc-options 115200:60 --bmsc-freq 0881
I see all the chips been set to the new freq then after that boom process crashes.
Initialization of the boards look all good.
Very strange.
EDIT: restarted using my old command line => cgminer.exe --bmsc-options 115200:55 BOOM they all run to 57 GH/s
EDIT2 : Switched for 60 ms. still around 56-57
that is strange... what are you running, linux or windows? doh, i can see that on the cgminer.exe you reported :-p do you have a linux box to test on? I got my Raspberry Pi, but i still need to buy an usb hub. mine sucks EDIT: I also run the your compiled version for Windows EDIT2: anyway, no big deal. i just have to set the freq to the boards, process crashes after the freq part. Restart it without the freq and i'm all good. I guess i have to do it for every power shutdown on the boards tho. EDIT3: running for the last 9 hours or so 0: AMU 0 : | | 59.11G / 57.30Gh/s WU:800.5/m 1: AMU 1 : | | 57.67G / 57.08Gh/s WU:797.5/m 2: AMU 2 : | | 61.96G / 57.31Gh/s WU:800.6/m |

well, got my ant blades down below 1 W/GH
254 GHS vs 241 W :-D (5x ant s1 blades) = 0,949 W/GH
Cool ! What is the voltage and resistance ? measured resistance is aprox 1.85k, voltage 0.75ish, but each bank has been finetuned for optimal performance, so they all vary, and they run at 200 MHz with timing 60 Mine are at around 2.75K / 0.84v doing 49.2 gh/s timing 55. I'm surprise you're doing better with less voltage. what bmsc-freq are you using? default, so 200 try these instead: option 'freq_value' '0881' option 'chip_freq' '225.00' option 'timeout' '60' option 'freq_value' '0981' option 'chip_freq' '250.00' option 'timeout' '55' tried that => cgminer.exe --bmsc-options 115200:60 --bmsc-freq 0881 I see all the chips been set to the new freq then after that boom process crashes. Initialization of the boards look all good. Very strange.
