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

even the best psu will fail if pushed to 80% of its rating for 24
so this would indicate your unit has an absolute max of 440w usable.

Running 750 watt Corsairs here at 700 watts with no problems, so I think a good supply makes a difference.

Then again I ran it at 800+ for a few days, so a really good power supply makes a difference.

I've been running 2 off of this for couple of months. @750w, sounds like maybe the same Corsairs.

No other draw - zero problems. ymmv

About how much power have people had their Chilis drawing? I think I saw 180-200W each but I don't recall the specifics. I'm asking because my 700W (552 on the 12V) PSU that has been powering 2 Chilis faithfully for several months now seems to only want to run one. If I plug both in they'll hash for probably 30 seconds then everything dies and I have to wait a bit and play with the plugs to get things back on.

The other reason I'm leaning towards a PSU issue is that when I had both running they'd average 36-37. Just the one running is now breaking 39 which I'm sure requires more juice. Thanks in advance!

I have chilis here drawing 220w at 38Gh, so I think you have been maxing out for some time.

I have a Corsair VX550 (its 7 years old) driving 2 chili very comfortably.
Alongside is my EVO labs 600w that can only support 1 chili.

Cheap PSU's will always loose in the end.

Well apparently there was a power outage over the weekend that I wasn't aware of. Perhaps that has something to do with the issues. Either way on a whim I shut everything down and plugged the second Chili back in and for the past 45 minutes now they've both been cruising. I do find it interesting that when I was just running 1 it ran about 3GH/s faster though. Will they dynamically adjust their speed in response to a power shortage? Or to put it another way - is it possible/likely that the Chilis have the ability to run at a slower speed if they sense they aren't getting enough juice to really push things?

It shouldn't be a heat issue - one is air cooled and the other is water cooled and they're positioned in such a way that they shouldn't be sharing any warm air.

My chili's at 38Gh draw 220watts
The bottom end units run at 33Gh draw 180watts

one with defective engines runs at 23Gh and 140watts.

If you are getting 39Gh then all your chips are good ones and running at top speed, (the power draw will be a lot higher than 220w)

The chili's will run anywhere between 23gh and 40gh depending on the power available. The voltage will regulate to meet this level.

Much below 23gh the power supply stays below its critical voltage and will crash.

4 chilis working stable ( even been Lucko's boards ) since an 1 month and half on Coolermaster b700 G750. no aditional load.
Only issue: power cables temperature is 55 ºC ( so somewhat hot.. ) at connectors. I think power will be near 150/180W but Haven't mesured yet consumption at power cord.

For me, chilis apears not sensible to small power fluctuations but hashing seem very sensible to room temperature.
Today total 143 GHS 131 GHs at pool 25,5 ºC room temperature. I have got in some cold days 145 GHs.
If room temperature is below 24,5 ºC i have a big trouble to maintain a stable setup

It´s absolutely the same I have seen for weeks now - lower room temps are really a pain for start hashing.
When they start hashing - they finally run stable. I too have some boards what are starting everytime on 15 °C without a hairdryer.

WTB one Chili. Located in Germany. Please PM me

Do you have solder skills??

...would have one what need FTDI chip replacement ;-) ... if you need a "good" one you can PM me with your price suggest.

[MrTeal]

Grown with care, coming soon to a farm near you.

Wow.. I love that pepper, must mean something fast is coming!

[nexus99]

I will translate that as meaning we have some Bitmine A1 28 NM Chili love coming. I hope I have enough BTC laying around for this ;-)

[ZBC3]

Is there a pepper spray coming?

[lightfoot]

I'll be honest: It's going to be a race to see if Mr. Teal gets the 500gh chili out before I deliver the 300gh Jalapeno. :-)

LOL... Best of luck. I would be beyond impressed if you can shoehorn a Monarch ASIC into a Jalapeno, I know I'd buy one.

[lightfoot]

Well, how hard can it be?

Seriously: The BFL chips are probably using the same programming because why change it? Based on the board picture it looks like similar power needs/provides (1 volt, 3.3 volts, 5 volts with 3.3 volts running the logic, 1 volt running the engines), and the signaling to these things is remarkably simple (SPIO, basically unbalanced serial, low rate). All the clocks, details, and fun stuff is kept in the chip.

In theory one would need to supply it with power, read the signals, and get rid of the heat. An adapter board could be built with solder balls on the bottom to match the jalapeno board, then replace the trimmer resistors to set the 1 volt supplies to 1.3 volts or so, then either hack the Atmel code to provision the work or use the defaults and go.

Heat's tricky, but underclock it a bit and put a nice heat sink on top and it might stay cool. Getting it to all fit in a jalapeno box might be the challenge, but wouldn't it look cool?

Man I hope your translation is correct. Mr.Teal's chili board has been my favourite piece of hardware.

Extremely reliable but also fun with everybody's different approaches to cooling and mounting. It made mining fun again when things had gotten a little boring with the ease of just plug and mine.

I hope I have enough as well.

[gateway]

One hint.. it will have no bfl chips on it, unless Mr Teal glues some on the pcb's as little rubber stoppers on the bottom

[daemonfox]

So where can we see some info on what you have in the works MrTeal?

I got BTC burning away ready to get in on a new 28nm miner.
