I have a treat for all of you. I compiled for Windows girnyau's gridseed fork of cgminer that includes the fine-grain freq settings and freq-per-device settings. Find it here: http://1drv.ms/1kKPsP2Please excuse the hasty readme file, I wanted to share ASAP. (Typical "be careful, unverified binary here" warning. Virus scan it if you want, I know it's clean.) Feel free to donate to: 1AvazUbrKwY8wuxNMGFtt5KqGW8WXdx4JB Cheers and enjoy. |

Cool! Progress!
What does your pool see? What are your stats?
W2014
Pretty amazing actually. Ghash.io LTC pool is showing me EXACTLY the same hashrate as CGminer. 3230khash for 8 devices = 403khash each. Thats the 1hr avg. I'm planning to run this setup 24hrs to get a better average but it seems spot on. |

Modded 8 units with the single bridge trick today. All runniung stable @ 950mhz and nearly zero HW errors after a couple hours. Pool (ghash.io) reports exactly the same 400khash as cgminer.
Tried 1000mhz on one of them and although CGminer said zero HW errors and 425khash, ghash.io reported 30(!!)khash over a 1hr average. Pretty clear that 1000mhz does not work. At least not the way i'm doing it.
Looking forward to getting ahold of that modified fork of cgminer so I can have a little more granular control over freq setting and trying 950mhz and 983mhz.
Cool, but..... how often is 'nearly' zero hw errors? I saw red nonce's for the first time 'since I look often', in days and days of running at 850MHz. Flooky! Do you mean that kind of nearly zero? If so, I'd be impressed with that. If not....ehhhhh....... In total for all 8 gridseeds, running for 3+hrs now, I show 3 HW errors. That seems to be similar to what I see for non modded 850mhz units. |

So what have you used to solder the bridges? wi did not see many pictures of actual mods around here  I had to go buy all new soldering gear. The stuff i've soldered before was larger wires. So: New fine-tip iron, some wire, some solder, a station, a headmounted magnifier, flux, etc. The first one I used a small peice of 30awg wire but found that it is easier to put just a tiny tiny drop of solder on the tip of the iron and bring that down to the contact points to make the bridge. The contacts are way to small to apply normal "wound" solder to. Hopefully all that makes sense. |

Great guide, but I think you really ought to mention the danger's with opening a PSU. I wouldn't want to see anyone seriously injured when they shock themselves by shorting a freshly charged PSU capacitor.
BE CAREFUL

Wow! What a day!
Someone once told me that the best way someone can believe in you is with their checkbook. With a new order averaging every few minutes, its clear that this community is giving us a chance.
It's made it even more clear that we need to exceed your expectations, as the bar is high.
Words can not express our gratitude for your support today, we are humbled.
Thank you
So far my interactions with you guys have been great. Clear communication (email/phone) and good pricing. Looking forward to getting my Gridseeds :-) |

Can we get a windows version compiled please? Great work thus far! |

Have you tried 1000mhz yet? |

Work in progress... (13 more on their way)
What's the deal with heat/fans... are they un necessary? Uses 7watts each in scrypt mode. No fan needed. |

Yeah you are absolutely right. Pencil trick just makes things worse. Even with 850mhz and voltage=1 now I get a lot of HW errors. Time to break out the eraser!
Edit: Erased and back to normal. Zero HW errors @ 850mhz. Damn - now to find someone who can solder a bridge that tiny.

Could this be done via graphite pencil mod?

Picture for the Gigabtye F2A85X-UP4 does not work.
I am interested in that one or the ASRock 970 Extreme4 mobo combos.
I will PM you soon.
Yeah, I haven't taken that picture yet as the mobo is still in a working rig - same with the ASRock. |

Building out my gridseed farm. Got more coming. The cables will be cleaned up soon. I'm using standoffs for stacking - handmade power cables - and yes the fan is actually a few inches off the wall. |

Just want to leave a note that Zoomhash has been an excellent seller in my experience. I have completed 3 transactions so far with them and all we're delivered on time and as promised. Excellent communication and willingness to work on price.

I can buy a 270x from you via PayPal but not gift sorry, I am fully confirmed and sending it as goods shouldn't be a problem as you will provide a tracking number correct?
PM Sent. |

Willing to split some DDR3 RAM? Thanks mate!
Let me pull what I don't need this weekend and get back to you. Will you still be interested after the weekend? |
