Nice results, goxed. What voltage are your boards at (once they're heated)?
The boards with good chips are at 0.9V, the ones with >=2 bad chips are at 0.95V impressive. I cant get past 0.88v (39-41GH per board) without having chips or boards drop to 0 hashrate or produce massive3 error rates time to time are you using heatsinks? especially on the regulator and the lower half of the board? I have put up a reference picture in this thread. if you copy that you should get the board up to 0.9v provided there's good airflow. I have good heatsinks but perhaps could use slightly larger ones on the regulator/inductor. 0.865-0.87 is good for 40GH on my boards, but the pencil mod ramps up to maximum (or minimum?) resistance over a few days and its difficult to get the exact balance. once it climbs to >0.88v the boards become unstable and i see high error rates followed by entire boards or just some of the chips dropping to 0 every few hours and upkeep is a PITA. i'm sure if i had cold air moving through the heatsinks (rather then the 21 C room temperature) I could reach 0.9V though, or at least achieve a stable 0.88v If you have 40GH/s stable I think you are at the limit already. Kudos! you can do more than 40Gh/s with by disable few chips or disable dead chips for OC.

Anyone had problems with a V1 M-board?
I have one board that the last two slots just will not work. Started within the last two weeks. Initially I thought that the H-boards had died in there, but after swapping around a bunch of H-boards, the last two placed in the M-board fail to be seen, no matter if they work in another slot.

what? Are you implying that disabling chips will make the board faster?

One of my October (v1.2) H-boards died on me. Just a reminder: make sure you have a backup SD card ready to go. In power cycling to test the H-board, I managed to screw up the originally SD card that came with the starter kit to the point that the OS couldn't properly boot even on a fresh, new image. Having a backup will save you from some future headaches.

Better than disabling dead chips are remove it and short appropriate jumpers. You save energy for rest chips and can overclock little more. If you haven't appropriate equipment for that, go to any laptop repair service. https://www.dropbox.com/s/xwl9p8pv1p0guh8/20131026_121407.jpg

Much better job than the person that used a power grinder to sand the chip (and the solder mask, traces, and surface layers) off the board. With the chip gone, that missing bypass cap at C4E1 doesn't matter, either...

Do you hate being that guy? Wouldn't be nice if you didn't have to ask? Dave and his team do an outstanding job. You are light years away from its effectiveness and professionalism. Don't come here asking for something you even barely can't offer.

Is there going to be a new release of BitFury devices soon? I may be interested in adding some to my existing BFL Singles.

Avalon started selling their Gen2 chips.
My gut is telling me the Avalon Gen2 stuff is DOA. Absolutely no point in using the Avalon chips when the Bitfury chips are superior. Best I can tell, anyway...
