available soon i hope! What are those 12V Supplies you are using? I have been unable to find dedicated 120->12v power supplies that are cheaper then similar-wattage desktop ATX supplies. (Ive seen several quotes in the range of $150/1000w when i can find on-sale PSUs for that with features like 6 or even 8 modular PCI-E cables

24" PCI-E cables with 16AWG wires and stripped ends - great for server PSU mods, best prices https://bitcointalk.org/index.php?topic=563461 also selling 6" M-F-M PCIe splitters and PCIe-PCIe
No longer a wannabe - now an ASIC owner!

Any chance the DZMinercoop will be getting these V2's?  It seems like they've had a very hard time getting the V1's to hash anything close to the original hashrate goals.

What is V1 optimal?

cgminer does 39.5GH/s without any adjustment at all.

I've simply not had the time to tune it to allow using anything but the default settings, and on default I get ~39.5GH/s
I also use Arch not Raspbian

3.5days running (since I had a blackout)
Code:

Is this negotiable? Looks quite high.

The link for the 4-board set gives a 404. What would one of those cost?
