How is the hashing speed of board
How much watt per board per 8 chips?
Topic: The Chili – 30+GH/s BFL based Bitcoin Miner Assembly - page 63. (Read 138078 times)
Here are pictures of my adapter kit for mounting the Hyper 212 EVO to a Chili board. Since I don't have any boards in hand yet, I made a simple cardboard model.

Notes:
* I recommend at least 3 full turns of the screws into the standoffs from each end for stability. If you assemble them as shown, the screws should meet right about in the middle of the standoff, about 4-5 threads (full turns) from each end.
* The number of washers inserted in the center of the X bracket affects the pressure on the chips/pads, though I'm not sure by how much. By my calculations, 2 or 3 washers should achieve the same pressure as the cooler would apply to a standard cpu with the stock hardware. The kit includes 4 washers for that location, so you can choose how many to use.
* The picture shows 4 pads, each 10x20mm, which you can cut in half to cover 8 chips. You can probably get away with not cutting them and covering 2 chips each if you position them very precisely. Make sure you remove the plastic from both sides of the pads.
* The 12mm long M+F standoffs I'm using for the board's feet, and their nuts, are the ones that come with the cooler and normally attach the backplate to the board.
I already sold all 17 parts kits I had for sale, but I still have thermal pads for 6 more boards, which I'll sell for $2 per board plus shipping.
Is anyone interested in these kits for batch 2? Let me know how many. I figure I can get more parts in as soon as Monday if there's enough interest (at least 25 kits to make it worthwhile).

Boards are going out as we speak, shipping will continue until they're all done.
Nice, folks buying them 20 at a time :-)
i cant wait to test my board 
happy happy joy joy
happy happy joy joy can i send payment for batch 2? and if yes
where do i send it and where do i send my chips?
where do i send it and where do i send my chips?

Nothing at market will break even if 30-40% increase in difficulty every 10 days forever. Hardware buyer basically betting it won't increase 30-40% every 10 days forever.
Have fun my friend no roi
This issue on ROI comes up a lot. Is there actually any product available today which has a positive ROI?
love the design, very clean, well thought out... /tip hat
doing quick math, that works out to about 4.5 btc + cooler for each 30GH board, right? Not counting cooler that's rougly a 4 month ROI, and that ROI is about to get much worse in Dec (8/mo) and Jan (11/mo).
I wish I'd had the option to buy this in August...
For board with 16 chips?
These boards only have room for 8 Chips.
I've some spare thermal pad 11W/mk, $2 + shipping for each (shipping from California).
Payments via Paypal only, shipping same day via USPS.
Each piece is 37x33mm (you normally only need 33x33mm)
PM me for details and purchase.
(The thermal pad is this one: http://www.frozencpu.com/products/16878/thr-164/Fujipoly_Extreme_System_Builder_Thermal_Pad_-_14_Sheet_-_150_x_100_x_05_-_Thermal_Conductivity_110_WmK.html?id=BTEHkam2&mv_pc=312)

I still have some pad left, left me know!

Look great power hashing per board and watt per board?mr teal
Depends on your board and cooling. The firmware changes voltage and per chip frequency in order to maximize performance while keeping temperature in check.

:)which final is the speed and the watt per board?ALSO any step by step details
how we install the thermal pad and the cooler at board
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.
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.

My cooling kit so far. Waiting on a back plate.
