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

[daemonfox]

Anyone ever get these running in Easyminer?

Just tried on an Android 4.2.2 Rockchip based mini PC and although it detects... it gets zero hashes.

This is the one i used to reflash - it had the slow rise on it before - this is after i flashed it with this firmware...

Ah, I was talking about when you tried to flash it back to the slow rise and it didn't work.

very pleased with the ones i purchased from Cascaders28

also are they running the latest FW?


idk dafuz is up with the formatting just scroll.

[Cascaders28]

I can't bring myself to quote that mess of formatting but this message is for you Taugeran

I sent them to you running the full power firmware. I was able to flash them to the 1V without any issue, but they slowed down to about 30GH/s on that. Granted they ran much cooler as well (55C instead of 70C) but I'm not paying for power so the draw was never a concern for me. I think I mentioned this, but in case I didn't they tend to top out around 33GH but once you get some air moving over the side of the board you'll get into the 38GH range. Glad you're liking them!

I tried with several android devices and found the same situation.

I went back to a cheap mini windows pc, the tablet recommended by BFL was just too expensive at the time.

That mess o formatting is what I got from running screen /dev/ttyUSB0 then zcx

I am selling some Chili boards.  They come mounted with accelero twin turbo 2, 3 of them are mounted with accelero mono plus

Have 18 boards available.  Please post your best offers or send me a pm.

I also have bfl gear available. 2 minirigs (500gh/s +-10%) and 9 single sc (60gh/s +-10%).



Thanks

Sorry to rain on your post... but @ $.10 per kWh and a price of $8 per Chili, you could break even in 45 days or so... but after that 45 days... its a daily negative return.

I will offer you $5 for each Chili for the entire batch shipped at once. $90 + shipping. ~.14 BTC + I will provide a label to ship if you provide weight and dimensions of the box.

Anything more means 100% loss of money for any buyers.

This also goes for the BFL gear too since power consumption is about the same...  you can't profit off these after 45 days or so from now at $.10 per kWh even at $.27 per GH/s. Similar to the Chilis, if you do wish to sell at this rate, I would offer $84 for one of the minirigs and I will provide the label. .13 BTC + shipping label.

Well, after a long and oddly enough profitable run I finally shut down my Chili. I had to turn it off to move it, and when I powered up it was giving me the four LED salute, which probably means the power supply is sunk.

Ah well, it did a very good job for me. Thanks Mr. Teal!

I think it's time to give up on my chili, it was runing fine several days after I removed the extra fan, but I found the device with leds 1 and 4 i guess on and 7 blinking, after restart the same. After power down for 10-15 mins it started, but with a simple restart of the miner and the chili stopped responding again.

I tried to flash the 1.1fw and the 14e normal fw - only led 7 blinking and with the following result:

Try getting the chili temperature below 25C.
They respond better to programming at this point.
They also restart better from 25C to 29C.  Above this temp, a restart is almost impossible.
If the onboard sensors read above 30C it will go into a waiting state until the temp drops.

Thanks for the info, I've tried it and it's better now, but after simple bfgminer restart I connot start it again:
 [2014-06-09 02:39:54] BFL 0: Failed to open \\.\COM12
 [2014-06-09 02:39:54] BFL 0 failure, exiting

I have to cool it down more to start mining, this is getting like catching the wind
First I have to cool it down, then I have to keep it warm to work without issues... nice1

Maybe a fw that prevents this waiting state will be nice, at 1.0V or less if possible I don't know the minimum for this BFL chip

Edit:
I can boot easier with the 1.1fw, 1.0 is almost impossible to boot ... maybe I can not flash it properly

If the board was from a Lucko batch then the 1.0v may never work, only the highest speed Chili's (38Gh) seem to handle the new ECO 1.0v properly.

Mr Teal and Lucko had some comments on this a few weeks ago.

EDIT:- check your cooler for contact with the chips

Erm no - i've not seen the link for this firmware - ive been away this weekend due to rebuilding all my PCs and mining rigs racking. I'm going to try again with the chili tomorrow.

This board is from Lucko's batch.

Now it's with the 1.0fw and when i manage to start it runs very stable:
 BFL 0: 66.0C | 32.18/32.13/31.32Gh/s | A:0 R:0+0(none) HW:1824/3.0%

Actually theese problems started after several days runing this fw and without the extra fan cooling the board and regulators.

I doubt that it will be the cooler contacting the board since it's runing now, only hard to start.

[hotwired007]

I managed to get my Chili (Lucko batch) working that i'd been having issues with after flashing the bios to 1.0v - it will mine happily IF there is a fan plugged into the fan secondary fan header - as soon as its removed the miner will not mine or respond to anything - i still cannot reflash the miner back but atleast its mining!

I spoke to someone else and they think there could be an issue with an overcurrent and need an additional resistor required?

Any thoughts MrTeal or Lucko?

No, there's no need to have a fan plugged in. The tach input isn't monitored.

If you can mine with the board but it shuts off if you remove the second fan, it sounds like there is a hardware fault on the board. I am not sure what the other person might have been talking about with overcurrent or a resistor, but nothing like that should be needed.

And oddly enough my "dead" Chili is back to life and fully operational. No more 4 LEDs.

Why?

Well, before I was going to add it to my collection I did a complete cleaning of it first with spray on electronics cleaner and a nylon brush, followed by a nice alcohol bath (95% isopropyl). Plugged it in one last time and...

It worked perfectly. Over and over again.

I think the problem is the circuits for the power supply on the side there are susceptible to either resistive or capcitative leakage based on dust and normal stuff. Why people don't conformal coat these things is beyond me. However cleaning it off with Alcohol fixes the problem.

Yes, it's hashing again now. But I will shut it down to mount it. Eventually.

Like old fashioned tv sets, the dust burns on, then starts grounding the high current items.
A Polish tv repair man near me, used to make a good living cleaning problems like this.
