XD

And Keefe, hopefully that will be sufficient, I'll just make sure to set them on top of a clean surface such as a block of wood or maybe some cardboard. I'm just putting all my miners in an empty room that has no furniture so I'm improvising as I go.

As warm as it gets in there I'm pretty sure that is exactly what it is saying!

Any new firmware for chilli?

[ryanb]

i got the shipping address for the chips from MrTeal but do i need to send anything with the chips so he knows these are mine?

To me it seems like a good idea to let him know your name and address

Is there a way to "force" the Chili to a higher target temperature?
My Single SC are running between 72-80°C and I assume that I could get much higher hash rates with higher temperature.
I guess it would require a firmware update or something.

Thanks!

We will be adding that to an updated firmware here in the next little while, along with a few other features.

What will be the other features?

So after trying to fire up the ~60 chilis and feeling the heat coming off them I have got to ask you how your cabinet is handling those hah.

We had to add a 25,000 BTU on top of the 22,000 BTU A/C unit we already had for the room.

Definitely underestimated how much heat these chilis make, the name fits!

They definitely put off some heat, but it hasn't been to hard to handle. Still working on tweaks. The fans on the chassis should be closer or just ditched and replaced with alternative higher power fans that can pull cold air in the bottom and push it out the top. The most interesting thing is that this entire rack is quieter than a 60GH Single, by far. MrTeal and ChipGeeek did a great job on the boards and they are averaging well over 32GH. By the way it's only 54 boards (6 per chassis).

For information, I think buying hashpower on https://www.cex.io is cheaper (and more convenient! you don't have to pay for electricity, not handle the noise or anything) than buying a Chili.
And also easier to sell if you want to...
(32GH/s = 4.16 BTC at the current price (0.13 BTC/GH/s), ie $748 at the current Bitstamp exchange rate ($179.80))

My referral link if you want to: https://cex.io/r/0/crazydownloaded/0/ (I'd get 1 GH/s if you deposit >=1 BTC)

What do they charge for electricity and maintenance fees?

What do they charge for electricity and maintenance fees?

Nothing yet, to my knowledge (I discovered this service today):
"1 GHS = 1 GH/s delivered INSTANTLY. All mining power is handled by GHash.IO (0% pool fee). Maintenance fee: 0.00 BTC (May be changed in the future)"

In fact they merge-mine NMC to cover their pool fees, but nothing is said about electricity (I doubt NMC covers electricity). Maybe it's like a "perpetual contract" or something.

Selling 2 Chili boards for 3BTC each if anyone is interested.

[nanook7]

I have some extra BFL chips to sell, don't miss you chance to get them into Mr.Teal's great board
BTC .18 each

Actually, here is what the site says...

"How can a GH/s be owned forever considering electricity costs and other fees?

Maintenance fees will be set per GH/s to electricity costs and datacenter fees. It may be adjusted according to the BTC/USD exchange rate because our fees are in fixed USD. If the maintenance fees exceed your mining income, GH/s be sold at current market price to cover fees. CEX.IO MUST buy back sold hashing power at market price to close accounts. At anytime you always have the option to request GHS withdrawal as hardware devices, just contact support to negotiate shipping details."

So it looks like the key unknown variables are... What are the electricity costs? What are the datacenter fees? Finally, I wonder if the way this exchange is set up would be in compliance with FINCEN and SEC regulations that have recently caused platforms to close our stop serving US customers.

I have to say that I am a big fan of bitfury. Really curious to know more about who is behind this service, and what the actual costs are.

Very interresting The maintenance fee is 0 for the moment: "Maintenance fee: 0.00 BTC (May be changed in the future)" (below the trading chart)

One last thing. It appears GH are selling for .13 BTC or $23.27 per GH/s. I am very happy with the boards form MRTeal and ChipGeek but actually have some I am planning to sell. I am willing to sell 10 that I have in hand and include the pre-installed Twin Turbo VGA cooler and PCI bracket for my cost (about 4.4BTC).

If anyone will pay over the 4.4 BTC I will donate 100% of the profit back to MrTeal and ChipGeek as a thank you for their hard work. PM me or make offer on this thread.

[MrTeal]

I'm a bit of a hardware geek so I'm a bit biased, but I'd much prefer to have hardware in my hands than any kind of purchased hashing power setup.
Much like your BTC, if you do not have possession of it you do not really own it.

Go back a bit over a year, and how many of the hashing power by the GH/s bonds are still around? GigaVPS is still paying dividends, but retroactive forced an at-your-cost verification process and changed the perpetual bonds into single year bonds. The majority of the rest took the opportunity of GLBSE closing to cut and run.

There are so many things that can go wrong with these scenarios from straight fraud to government regulation changes to the medium of exchange shutting down that comparing having hardware in hand vs having the promise of someone else continuing perpetual payments and not screwing you/quitting/getting hit by a bus on a straight $/GH/s basis isn't a proper comparison.
