Does anyone know if it is possible to run any variation of cgminer or bfgminer on v3 boards? I understand it wouldn't be officially supported, but I am willing to experiment a little and/or compile my own copy, etc. I found some old forum posts elsewhere hinting that it might be possible, but they are very old and appear to be specifically for the v1/v2 boards and maybe were specific to the European version of the hardware (is there a difference?).
For reference, my reason for wanting to do this is that I am really trying to get my rig working with multiple pools. At least for failover, but ideally for load balancing as well. Both are built into cgminer/bfgminer.

There was a person in this post that got it working on V3 and had a nice write-up on how he did it, I am a bit too lazy to dig it up but it was in Mid November when he posted. You may be more willing to dig back a few pages in this post than I

Even at the discount rate these don't make financial sense. What a shame, I really wanted to top off two m-boards that I have.
klondike_bar, which h-cards version are you interested in? I wonder if we're allowed to mix and match the type as long as the total ends up being at or over 10.
V1.2 cards. I want 3-5 card for myself, and will happily reship within canada or to USA via xpresspost (2-3 day service) if anyone wants to go on the purchase with me. Did this arrangement fall through? I haven't heard back from you.

Anyone else want to go in on a group buy? If anyone wants I can organize one for anyone in Canada.

You may be more willing to dig back a few pages in this post than I That was me. The post is here; getting bfgminer running was pretty straightforward. It needs to run as root to talk to the Bitfury hardware, but so does chainminer. Action shot: I have a couple of BFL Jalapeños and a Klondike 16 (finally arrived this week) hanging off it now; with two v3 H-boards, I'm getting a total of about 85 GH/s. Also arriving this week: one of these open-frame cases. Here's what the whole rig looks like now: All of the miners run off the power supply in the Bitfury rig; the Klondike miner pulls from a modular Molex cable, while the Jalapeños pull from the ATX cable through a modified ATX extender (pulling 12V from the appropriate pins and hard-wiring PS_ON to GND). At some point, I'd like to run the USB hub from the power supply (tapping 5V off of the ATX extender would work) to clean up the wiring a little more; it'd eliminate a wall-wart. If I can move the rig closer to a network jack, I can get rid of the wireless bridge (I'd probably put it back on its previous duty as an 802.11a/n access point).

I did find you post and I used your image for a while, but my v3 hardware is apparently even more unstable than yours and while it does mine, there are still lots of errors and observed hashrate is about 20% lower than with chainminer (presumably because so many cores are erroring instead of hashing). I wonder how viable it is for me to adjust the trimpots to reduce the voltage and un-overclock these just a little bit to increase stability. I'd trade a little bit of hashrate for something that was more stable and for the ability to use a miner that gave me failover capabilities for when my primary pool is acting up. But I don't own a voltage meter and I'm hesitant to just randomly start turning the trimpot "a little bit" counterclockwise.

Thank you for your anecdote. I thought I was going crazy there myself for a while, discovering this same behavior.

Did this arrangement fall through? I haven't heard back from you. I didnt get any answer from dave if boards would ship immediately or if they were still on the way from fabrication next week. In either case, I have decided that $750 per card (~0.9BTC) is excessive for the product considering even a 35Ghash speed. Obviously im not the only one, since MBP has sold all of 22 cards in the past few days. When Dave drops the price to something reasonable, and/or prices his store in BTC, I would be more than happy to organise a groupbuy for a few ontario residents since there seems to be 3-4 people looking for a few cards each. Hopefully bitfury comes to senses and drops the price to 0.7BTC or less over the weekend, in which case i would go ahead with purchase

My cards are all stabilized and have good fans directly next to the cards (similar to yours, but without the great case (I am on the waiting list for one)). My rig is very stable with chainminer. Just not with bfgminer or cgminer. My only issue with chainminer is the lack of support for failover. I'll try heatsinks. Which piece is the voltage regulator and are there any gotchas or risks to be aware of?

The voltage regulator that needs to be heatsinked? It's the dark gray integrated circuit in between C01R and the Pulse inductor. I attached mine to the back rather than the front, though. It is tricky either way because you do not want to accidentally short the other components. On the front, the thermal conductivity is not as good. On the back, the heat sink barely contacts the area where the regulator is attached due to live traces and components.

For some-odd reason I thought it was C06 (SH 100 16V) that needed to stay cool. I guess it doesn't really matter as I have a hurricane blowing on those spots either way, but would be good to know... Thanks for the insight ! Guess it's off to EBay with me to buy a bag-o-heatsinks.

Its a night and day difference for my cards, it runs with the heat sink in those locations and it will just plain shut down without them.
