The Chili – 30+GH/s BFL based Bitcoin Miner Assembly

[ryanb]

with the hardware in hand if any sha coin becomes more profitable than btc you can switch your miners to the new coin

and you are in control

Fired up my first Chili. Its hashing at 30 GH/S. Anyone have any thoughts how to squeeze 5 or 6 more GH/s out of the unit?

Blow more air on the board itself, especially the backside.

Get some extra fans blowing on the back of it to see if you can cool it more.  My coolers are working the top of the chips well, but the back of the board is where the heat is for mine.  Try a box fan and see if the firmware takes advantage and pumps up the hashing speed.

As others have said, cooler = faster.  The back of the power regulator area is a good place to keep things cool also.

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.

I totally agree, it's a risky approach. I like to diversify my portfolio. Personally I will definitively keep my own hardware + do some trading on their service.
They own like 19% of the total network power, so I guess the risk is somewhat limited, they must have some big money behind them.
What I like with their service is "infinite compound interest". I can buy more power as soon as I'm paid for a block.

thank you MR TEAL you guys rock the shipping was super fast
i got it today i opened it and dam its soooooooooooo smalllllllll
BFL got nothing on this design. i really cant believe how small the unit is
when i got it in a small package i was like wow its like half the size of a gfx card
great work i will be testing asap once i throw a cooler on it

WOW.... amazing   

Atleast fcking check BFL threads to see Singles being posted by members, noobs.

all i was saying is the design is sexy

I'm hoping the new firmware will be up soon so I can just plug the boards into my android... decided to start running EasyMiner on the android because I needed to free up my laptop.

I can't seems to get my board working. Using bfgminer 3.3.0 I keep getting:

"BFL 0: Failed to send queue, and queue empty; retrying after 1 second"

Any idea what's wrong? Cgminer with zadig didn't work either.



I received 2 boards and both showing the same error.

I think its probably a bum chip.... or several sub par ones? Board #2 right next door is hashing at 35 GH/S with the same cooling.

Try a different pool. Or maybe a newer CGMiner version. What is your start up script?

[shade88]

Here I use newest cgminer with zadig.



"cgminer -o stratum+tcp://stratum.mining.eligius.st:3334 -u myaddress -p x -G"

Not hashing, doing nothing. Try it on 2 PCs, same thing. My Bitburner Fury works fine. Change usb cable, same result.  

LED 2 blinking
LED 5,6,7 on
LED 1,3,4,8 off

This is a workaround version of BFGMiner until a new firmware update for the chilis

Here's a modified version of BFGMiner, I also included the driver inside of it as well that should fix your problem. (I don't know much about CGMiner though)

http://www.speedyshare.com/uKncp/BFGMiner-Chili.zip

Open up bfgminer.conf and change the Pool and Username to whatever you want (It currently uses mine so make sure you change it)
Run CDM v2.08.30 WHQL Certified.exe to install the correct driver for windows

Once you do both of those, just open up bfgminer.exe and it should read from the config automatically and start hashing for you.
If it doesn't see the Chili, all you have to do is keep BFGMiner open, unplug the USB, Plug it back in, press M then + then type all or auto and enter. It should find it.

Please note if it still isn't working then you need to exit BFGMiner, unplug you chili power, plug it back in and wait for all the lights to stop blinking. If you try to find the miner while it's "Booting up" it will have issues.
"Booting Up" is the two most right LEDs (Closer to the Power) blinking back and forth. Again once all the LEDs are not blinking anymore it should be ready to start hashing, start your BFGMiner and follow the above steps.

Let me know if this helps

[shade88]

It's working, thank a lot Bargraphics.


I can confirm that Noctua NH-U9B SE2 92mm SSO CPU Cooler compatible with The Chili. It came with a backplate, 2 fans, and huge heatsink. Need some washer or spacer to make it fit though.

Bargraphics, is that a 32-bit or 64-bit build?

If it is 32-bit, is the 32-bit version of BFGminer safe to run in 64-bit Windows?

I'm about to build my Chilis and I want to make sure I'm on the right track.

64bit I believe and yes I think even 32bit can run on 64 without issue.

what is everyone using for thermal ?
pads or paste

what pads are you using if so

what is the the best option for a $50 or under heat sink

•   A thermal pad is recommended over CPU grease as it cannot be guaranteed that all the dies will be coplanar or at the same height, I recommend this one for reasonable price and good performance

Recommended Cooler #1 – LGA1155 based
Coolermaster Hyper212 Evo
The Hyper 212 Evo is a good cooler to use this with Chili, although the included mounting hardware does make it a little difficult to use. I would recommend using these spacers instead of the supplied ones
http://www.mcmaster.com/#95947a310/=oridfb
and screw them in with some M3x10mm screws
http://www.mcmaster.com/#92005a120/=oribhm

Recommended Cooler #2 – GPU based Arctic Cooling Mono Plus
http://www.tigerdirect.com/applications/SearchTools/item-details.asp?EdpNo=7983391&CatId=99
This one is a little simpler to apply as a GPU die is about the same height off the motherboard as the Chili ASICs. It’s nice because it comes with a bunch of little heatsinks you can use on the VRMs if you want, too. I still recommend a backplate, similar to what you would use for a GPU.
http://www.arctic.ac/en/p/spare-parts/536/eva-foam-und-gpu-back-plate.html#
Also, I would assume you’re going to be mounting them vertically if you’re doing this, so you’ll probably want to pick up a PCIe bracket.
