Don't know where you are running bfg on but I had trouble with it on windows, not sending shares.
Never had any trouble since on CPUminer

I have now done 4 units, here is some of my handy work  two units have thermal compound on the chips while the other two i have reused the existing thermal pads. I will post a comparison in 24hrs. |

I posted an idea here: https://bitcointalk.org/index.php?topic=482352.msg6222366#msg6222366 to resolve the shoddy work on the heatsink/pcb design in regard to it not making contact with all 5 GC3355 chips due to two components that are taller. It's easy (if you have a steady hand) and takes about 5 minutes...afterwards you have perfect contact to all 5 GC3355 chips. |

Good news, but i think it isn't worthy to buy, one can buy even more ltc than buy this little thing

I've been able to run 1200Mhz stable (around 510Kh/s-515kh/s with 0 hw errors). I ran it last night at 1250, but it has more than 20 hw errors at 531Kh/s. Before doing this I was only able to run at 1125Mhz, I could hit 1150 but accumulate hw errors. |

Wolfey2014... seriously did powersup ask you to critique his picture. I can usually just overlook members arrogance but you are something else. I can not find any threads where you don't post every day about your services. Please show some respect to fellow members.
Yeah really who gives a shit what it looks like? If it works that's what matters and wolfey is trying to charge $40 to mod one unit.... I think this guy is crazy. I did all 14 of mine and they weren't pretty but they work and that's honestly all I cared about |
Bitcoin is gonna hit 100K usd

For me, if you have only a few miners CPUminer. It works great for me |

Hi All. Thanks for all the information! Lots to go through but I managed to Mod my first gridseed today. I have 10, so I just did one to start with. I am having some trouble though...  Any help would be greatly appreciated. So I have 10, and with BGFminer I can see all 10, but can't figure out how to raise the clock rate on just the one I modded. So I tried just plugging in the 1 I modded, and raise the clock to 1150. It goes up to just around 500kh/s, as I expected, but never seems to accept any hashes. I can't figure out why. Also, I saw some pages back, someone who has around 80 of these running and is able to adjust the clock rate on any individual gridseed. That is what I need to do, as I plan to mod each one at a time when I can find the time to do it. His screen looks like he is using cgminer, but I can't seem to get that working for me, even with the zadig drivers, it never finds the asic. Plus I have heard that most folks are having trouble with cgminer as well. Any idea why the modded asic won't accept any shares? Also, is there a better mining software that I could use to have better control over individual devices? Or maybe a config I could use in BFGminer to do the same? I am very confused at this point, as this looked like an easy Mod, but I can't seem to get it working. I kniw I did the Mod correctly, as I am an electronics engineer and have been soldering all my life, and have a professional rework station with hot air and fine soldering iron, we use 0402 components all the time where I work. So I don't think there is a problem with the mod, it must be software based. Please let me know what I am doing wrong, or what I should be doing to get this to work. Thanks! |

Hi,
you cannot set individual speed on BFg only CGminer and Cpuminer
All I can tell you is that I also had problems with BFG had several plugged in and only some of them submitting shares while hashrate was displayed in bfg corectly. So I went CPUminer, it's a pity we cant see the speed in CPUminer and do not understand someone has yet fixed this but it works great.

I tried cpminer. I think it was working, but since I am not familiar with it, I couldn't tell for sure. Also, since I can't see the speed, how do you know if the mod is working? Seems like bfgminer only works on unmodded gridseeds. |

You can actually. I haven't found how to set only 1 with many units connected to the same instace but you can run this command here: bfgminer.exe --scrypt -o ltc.give-me-coins.com:3333 -u username -p password -d gridseed -S gridseed@\\.\COM3 --set-device gridseed:clock=1000 @\\.\COM3 is the COM port for your device. Kinda running late, I'll expand more when I get back from work. |

Well, I am used to cgminer, and I see that you can adjust each one individually with that. But I can't seem to get it to see my miners.
It seems pretty buggy.
Is there some trick or step I am missing to get CGminer to work with windows?
I use it for my GPUs and it has always been rock solid. Just no luck with these gridseeds.

I am using Cgminer on W7/64 since day 1...Rock solid with me...I CAN set not only individual miners, but even individual chips speed within the particular Gridseed... Zadig driver is absolute MUST...have to change STMicroelecrtonics driver to => Win USB driver v.xx.xx.xx... I am un-plugging the USB cable first...power Off-On on the miners...wait like 30-60sec...plug the usb cable back to the computers USB...start Cgminer...bat file works for me...immediately recognizes them... and is hashing right away...no problems for days... Hope will help... ZiG Edit : Make sure that you are using USB 2.0 port...NOT USB 3.0...on the back of your PC...  |

I also had problems with bfgminer submitting shares. It would show hashrate, just would never see any shares accepted. Right now I'm using cgminer and it runs pretty solid. I've been kicking around trying cpuminer, but cgminer is working so well right now I'd hate to do something and screw it all up.

I have noticed a few people use girnyau's cgminer which I'm using on a pi and so far no problems. Its easy enough to find with google. use --gridseed-freq *GRIDSEEDSERIAL*=*freqvalue* |

what is better in long term in gredseed??
only bridge (1.25v) +2w 1000mhz
or replace the resistor 33kohm->47kohm approx +10w 1150mhz

Well...with the bridge you can probably still dual mine sha256 and scrypt if that matters to you. I know with the resistor mod, you can't (specifically...the 3022m mosfet HIGHLY disagrees with it). Personally, I did the resistor mod, milled out part of the heatsink so it makes full contact with all 5 gc3355 chips, and ditched the crappy thermal pad for some decent thermal paste. I'm running at 1225Mhz (521Kh/s) with 0 hardware errors now. Scrypt only - I don't dual mine with this one. I might dual mine with another just so I can get the fraction of a btc out of a pool. |
