Bought two SP20, very happy with them ! I run the fan speed at 20% on both units. The problem is => I have one of the unit that is having a "Resonating Wave" sound at 20% speed. I know it's bad luck. Is anyone else experimented the same thing with a unit ? It's like going on a medium-high pitch every 2 second or so ... "wouuuuuuuuuuuuangggggg ....... wouuuuuuuuuuuuuuang" (<= hahahah nice try isn't  ) I tried to use foam just to try to block the wave with no luck. I can ALMOST get rid of it if i play with my hand and the airflow. I guess if i could run it at 21% or 22% i might get rid of it. This is soooooooooo unlucky Thanks ! i had one unit resonating like this. changing fan to 30 fixed it, paradoxically. yeah i kind of think of increasing the fan speed but it's already to the limit for noise it created for my in-house mining. (i wanna keep my girlfriend). So i will try to set it to 30 and see how it goes. thanks !  EDIT: How much louder it is from 20 to 30 ? I'm not home at the moment, just curious |

Chaositec,
Did you manage to get your hand on one of the prototype controller board ?
nope... Just asked Jabber for some news and he's currently overwhelmed by all the command he have for his breaking boards business. He will assemble the prototype as soon as he have some time. |

Anyone else run as much as 6 CP2102 on windows ?
I'm having a very strange behaviour. Using only 4 cp2102, everything is rock stable. With 5 i'm getting a little more HW (especially on one card) and with 6 ... i always have a card that throw a ton of HW, i'm pretty sure it's NOT the card as the problem looks like to appears on a random AMU. (After a reboot)
Thanks
I do NOT have that problem, but it could be due to all those units using the same device driver file. If you go to one of the units via control panel properties and find the path to the driver, then browse to the folder and create a few more folders under it (you can name them as you wish) and copy the driver into each folder. Then re-assign the drivers for your CP2102's to the different drivers in the new folders, ensuring each folder driver is assigne to only 4 devices (4 being your magic number!). Doesn't let me update it with a different file ... windows always say "Already installed with the lastest version" ... Allright, after many error and retry. The problem might not be the driver or the cp2102. Since my command line when I set the freq "cgminer.exe --bmsc-options 115200:60 --bmsc-freq 0881 --hotplug 0 --lowmem -o stratum+tcp:" crashes at the end. I restart CGMiner after that and i found out that if i run the first command (Set freq) multiple of time, the HW are almost gone. So... mystery here but my tactic is working. HW went wayyy down except one board which throw more HW then all the others. EDIT: Giving up, can't find what the f*** is going on. often i find that when i start up the boards for mining, they will throw a fit with HW, but after they get warmed up, they all settle down, so start them up and let them run for 30 minutes, then reset the stats on cgminer, and see if its become better I got about 0.85% HW with 1.3% Reject after like 3 hours. I clearly notice way more HW then i had with four cards. Now running 8. I could stand 57.2gh/s steady, now getting 55.x on all 8 cards. not so bad after all |

Thanks for the tip, I will try it ! |

I made a bad manipulation and I broke one of my board. I pulled off the RIGHT trace on the board for R3 resistance. I'm trying to figure out if I can connect my wire somewhere else, if possible. Sooo if anyone have an idea, it would be awesome ! Thanks Can you post a photo of it please ? I can review your circuit and tell you how to bridge it. This isn't the same board, but the broken trace is the one with the red wire. Thanks  OK this is an easy fix. Also I recommand you solder both pins prior lifting the resistor up or get a wider flat tip and groove out the middle so you have a U shape tip to de soder it better from the board. Here is the pic you need to fix your board: https://www.dropbox.com/s/3nxstwkm4fehwm7/Photo%20Dec%2026%2C%2012%2044%2030%20PM.jpg?dl=0 I do hope you get it fixed :-) If not let me know because I do offer those resoldering with a fixed resistor too. Thanks for the info, since this isn't my day-to-day job. Will you explain more in details exactly what I have to do. From what I understand, i need to relink C9 with C8, C4, then re-link R3 with C9,C8,C4 to C3 then all of them to C2 ? Thanks ! It really depands on how much you destroyed :-) The manual red marked line is the linking itself so if you only damaged a little bit on the R3 itself just run your wire to any of the other red marked point with a solder point. And you are done. C4 is perfect as a measuring point. If you use an OHM Meter you should read from C4 to all those point ~ 0 Ohm. Also instead of using a POT or POTI I do always just resolder a resistor in place which has 1% tolerance in this case I do use a 4.12 KOhm resistor. This eliminates your issue with the POT to adjust :-) many Thanks !! |

Anyone ordering from Montreal ? I would like one of those ! (Cannot really take two)

Indeed. Congrats on hitting a year. How long have the rest of you been mining? I jumped in around the beginning of the year.
Signed up with bitminter July 19, 2011, got my first bitminter block Oct 8 2011... I think when I first started here bitminter had only found like 3 blocks so far Love this pool! thanks doc! Started in May 11 of this year (I know i missed the boat) with an old BFL 60gh (more like 57GH) and now running like 2.0-2.05TH. I will add a bit of more power this week as I mod more S1 boards (got 3 running 24/24) to create a huge AntFurnace |

How the the "pay with USD" option work out ?

Just my 2 cents ...
The "dent" you're speaking of on the left side of your Mac is really close to your hard drive. He might have been damage by the hit...
I suspect your problem is directly link to the hard drive.
