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

[markj113]

Sorry ahead of time for the low quality images.  Also, I figure everyone is already past this step at this point in the game... but I'd post it anyway.

Originally, I was going to use the ARCTIC Accelero Mono Plus VGA Coolers and grab some PCI brackets, but that setup was considerably more expensive and proved to show lower hashing results as posted by others.

Then, I was going to do the double Antec Shelf idea like MrTeal. I ordered 8 coolers for 4 boards, but I tried it with a single one and I am fine with the results... so now I am going to buy 4x more boards to use up my 4 extra Shelfs.

So to mount the single shelf to the Chili, I mounted it directly to the board with the provided 1156 back plates.  I mounted the top mount to the heatsink as it was directed in the instructions (to the underside of the heatsink).  I then used misc computer screws which threaded into the back plates... I have a ton of screws laying around from buying internal computer devices (CDROM, floppy, etc drives) and they provided a very tight connection.  The board doesn't look like it's bowing at all.  I used nothing besides a rice sized amount of the Antec included thermal grease on each chip (maybe too much but it seemed to work).  I didn't really think about standoffs, since I have them mostly sitting in their sides like the first picture showing the back plates.  If you wanted to sit them upright, they sit on the back plates.  It's probably not 100% safe (something could short the power solder points underneath), but oh well. It works for me.

I tried one Chili with a thermal pad, but that one got 27 Ghs.  I redid it the way I did the others and it raised up the Ghs to around 34 or so.

All in all, I'm getting between 34 and 36 ghs.

Followed your guide and fitted this cooler, took 10 minutes and very easy to do.

Used the bundled arctic cooling TIM and getting 33.07 gh/s

Thanks

Edit:

added a small fan blowing directly on the Mosfet's and now getting 36.71 gh/s

I updated the firmware. I confirmed 4 outer and 4 inner leds are blinking in turn. After power cycling, when I check the firmware version, it is still 1.0.0. What's the problem?

Okay. I found this. I believe it should show up as 1.2.14e Version 14d and earlier reported as 1.0.0

Yes that is correct.  Perhaps you have an older version?  2 have been released so far with 14e (1.2.14e) being the newest.

Hi MrTeal and ChipGeek!

Two things... 1. Chili is running like a beast... no issues to date and already paid itself (thanks to BTC surge lol!) and I already paid myself out.

I am now looking into what I plan to do come February when the Chili is no longer as profitable, so I asked myself what has shown as the best option in that time frame, and what else does MrTeal and ChipGeek have up their sleeves? That leads me to a two part #2...

2. A. Do you have any new developments planned for next year? I would kill for a 28nm MrTeal miner!
    B. If you aren't up for developing another miner with 28nm chips... what do you see as best performance for your $ options come February?

Do you see any particular miner being ahead of the rest come February? Anything specific you already have your eye on?

Water cooling for a Chili

Here is an interesting water block that should fit on the Chili.
It may need a copper shim to lift it away from the board, and it will need mounting plates.
with this size of cooler it may fit into a single card slot. (with some plumbing and a separate pump and powerside fan)

Here is a pump

Backplates  and top plate...........but need drilling...........(Probably cheaper than Making them at home, but if you use these It will need a bigger slot space)

and the data sheet:-     http://www.cui.com/product/resource/vhs-45.pdf

Edit:-  For the Chili, the holes need to be 53.2mm x 53.2mm

Photos to follow.

i'd always go with a copper waterblock aluminium blocks will need additives in the water

Chili Minions! With 4 minion chips!

This is exactly what I was thinking!

http://www.blackarrowsoftware.com/store/minion.html

Too bad they shun group buys... Teal and Geek or a benefactor would have to plunk down solo up front and allow us to buy a whole miner from them in order to use Minions.

But 460 - 500 GH/s on one card is sick... and if anyone can do it better... a Minion based Chili would be the ticket!

Mr Teal and ChipGeek, selling pre-orders?...........will solve the problem.

Deposit = chip price

Mr Teal need some help,

had the miner delivered 2 days ago from your last auction, its has worked for just under 24hrs but now will no longer mine.

When I plug in the USB cable its says "USB device not recognised" or "One of the USB devices attached has malfunctioned"

All the lights flash on for a split second then lights 7 and 8 flash for a few seconds before going after which I plug in the usb cable/

I am using bfgminer on win7 64bit.

Tried re installing drivers but comes up with same error I have also tried extracting the drivers to a folder and manually installing but no luck.

Looks like there is a hardware problem, how do I go about exchanging the board if its a worse case scenario?

@MrTeal,

I could have sworn I saw a post in this thread talking about pricing for batch 3 populated boards. Request an update on the latest of batch 3. I'm very proud of my 3 chilis so far even if one of my Twin Turbo fans is slightly unbalanced causing a rattle which drives me batty.

Request an update on batch 3 please. I'm interested in buying populated boards.

[ryanb]

i would like to know the price on batch 3 without chips

and when should we expect them to be delivered?

you aren't crazy... I saw it too... it said $750 fully populated (8 chips I assume) but it has been edited out of the original post now.

[MrTeal]

Yeah, we were planning on selling them through this thread, but are going to hold off until we're closer to shipping. I'm thinking we might just do another auction similar to what we did this last time. It seemed to work pretty well and really cut down on the administration time.

Good call. Sell em all in one shot (maybe two lol).

Any insight on the other questions above about future projects with 28nm chips?

I can help you guys out here if there is some interest. I have the first 500 Minion Chips already reserved for DiY, I am just waiting for final data sheet to be released before I open it up.

[ipxtreme]

yes, it looks really nice, if an rpi could control it...would be awesome!
Im asked about the HSF's ... because of choosing between the rack version or the "open air" version w/ blue fans.... didnt know which cooling would be better.

Ah, a little searching found it. I've never heard of a Sunzi x6 before.
You'll have to ask CrazyGuy about it.

Well its just 6x chilis arranged.... so ... same thing applys bout if the 212 heatsinks are good or not on chilis and if mine peon can control them =)

MinePeon on the Pi works well with the Chili.  As its a cheap device buy yourself 2 units, (one for running and one for backup) (or use them both and split the load)

Edit:- http://rdmsnippets.com/2013/07/24/mining-bitcoins-with-usb-block-erupters-a-raspberry-pi-and-minepeon/

Thats great. How do I get the power supply to turn on without a motherboard ATX connection connected?
