so you can put it back on later when you move the HS to your new 50PH/s Intel ASIC machine in early 2015 when BTC hits USD$5000. Haha I think I'm just going to go with the more permanent route since that means I can just go to Home Depot. So when these bad boys ship are you going to provide tracking or is that too difficult? Thanks again! This is exciting.

Thanks again! This is exciting. Will we get tracking numbers before delivery? I'd hate to be away from the house when it arrives.
Yes, I'll email/pm tracking numbers once we ship them.

Yes. The factory testing is running cgminer on the Raspberry Pi. We're running 6 Chilis at a time that way using a powered USB hub.

mr teal,
great job on the project.
can someone post a list of the minimum equipment to get this running (excluding the host hashing system).
For example people are saying
thermal pads vga coolers case fans or cpu coolers
I just don't want to get this and have 2-3 days of downtime waiting for accessories to arrive. I assume heatsink and fan aren't included and a gpu fan is required.
a write up of compatible coolers etc in one location would be very helpful
thanks

You'll need a mini USB cable, a cooler, and a thermal pad. I'll be putting the Hyper 212 EVO coolers on mine, and I'm selling adapter kits (including the 11W/mK thermal pads) to mount those coolers nicely on these boards and also support them horizontally (such as on a shelf). You'll also need a power supply that can push ~180W on a 6-pin PCIe connector. Ideally your computer's power supply has a 6+2-pin PCIe plug so you can be sure it's designed for at least 150W.

I got a 620W PSU for 4 boards according to MrTeal's recommendation, hopefully that's enough.

What model? That seems like it could limit the overclocking potential.

This one: http://www.newegg.com/Product/Product.aspx?Item=N82E16817171068The computer's on its own power, I just needed something for the miners. I didn't think about the power needed for the overclocking aspect, and I was looking for something affordable.

i have a 600watt PSU that i have a blade connected to it and i plan to connect 1 chilli to the same psu it is bronze rated will it be enough?

Well, I suppose I could always buy a second one, if the first one isn't enough. I have plenty of computer stores near me with PSUs.

I plan on supplying up to 200W (on the DC side) to each unit, so I can overclock the units as much as possible, at least for the first month. As difficulty increases, I'll downclock.

Yeah, 200W per Chili is a good budget. At the moment the firmware goes for the maximum hashrate allowed for the cooling solution provided. Colder - faster hashrate. In the future, we'll release a new firmware that will further support underclocking to reduce power. As a couple of data points - in production we're using a TIM that is not very good but is very durable and Chili slows itself down to keep from overheating. This gives around 20GH/s and under 150W. But with a good TIM, we routinely are getting over 30GH/s and more than 150W. Of course we cannot guarantee that speed for all boards, but it seems possible on the few we've tested. Keeping the chips cool will get more hashrate.

I see two power draws at the wall in the thread for 30ghz; 130 & 150 watts. Would you please clarify which one it is?
Any idea how much heat is actually produced by the 8 chips? From the BFL specs it would seem 8 would generate @ 100 watts at their normal operating voltage.

Keeping the chips cool will get more hashrate. What are your thoughts on cooling capacity of the Hyper 212 Evo vs the Twin Turbo II, with the 11W/mK TIM? I personally prefer the parallel airflow direction of the former. But I want to be sure I'm not limiting my hashrate.

Hrm, fine, ordered a second one. I'll just keep it handy just in case. Maybe if I make a custom replacement for the laptop it would come in handy. Though, what's the cheapest option that can stably run bitcoind, p2pool, *and* bfgminer? For now I'm content with using my laptop because I rarely use it but I would like a more long term solution.

The W/GH curve isn't linear. For example, going by some numbers I've seen, dropping from 38 GH to 35 GH could save 40W. That will be a good idea pretty soon.
