Is there a changelog for the firmware?
More to the point, is there any need for updating the firmware on an old Chili ?
I have no problems with mine, but I could use something to decrease the amount of HW.

Might be totally off on this but do you have them on unpowered USB hubs?

If you are getting nothing but HW Errors it is likely due to your USB Hub/Or you started the mining program while the Miners were still booting up.

Occasionally I'll have one that just causes issues out of the group (never all of them) and a quick reboot and changing the port the USB is plugged into fixes it.

Thanks for the push in the right direction MrTeal! By going dead I mean they put out tons of hardware errors and eventually BFG and CG both claim that they are turned off. Theres no real heat coming off of them either so I believe that they are in fact off.

Using 3.8.3 of CGMiner and 3.7.0 of BFG.

The current firmware is 14e (https://www.dropbox.com/s/zoewijezzhfl3bs/Chili14e.hex), and I believe it should show up as 1.2.14e Version 14d and earlier reported as 1.0.0 because of the way old versions of cgminer handled the division of work between the 1.0.X and 1.2.X BFL firmwares, so we had to report as 1.0.x

For the issue you're having, when you say they all go dead what do you mean? Do they go zombie, or put out hardware errors? Have you tried running just one as a test before adding more in?
Also, what version of cgminer are you running?

OK, so all the way back to post #586. Firmware is stated as being 1.4 from the looks of things?

I've got a board that, again assuming I'm doing this right, the firmware flashing program claimed to have 1.0 on it. I thought I flashed it with 1.4 but after a power cycle the board still shows as having 1.0.

What am I doing wrong?

FWIW, I'm having a HELL of a time getting these things to hash in Win764. I had them working on a computer at home but so far three computers in my office dont like these things. They all get detected by the OS as BitForce256, windows does its thing and installs the FTDI driver and all seems well. I start BFG, they hash for a split second and ALL go dead???

Change the driver to WinUSB via Zadig and start CGMiner and they all do the same thing (by all I mean all 12 that I have).

Anyone have any ideas?

Could be firmware but I cant seem to get this flash procedure down right...

Is there a way to get the serial # in cgminer?

i wrote the serial number (last 3 chars.) from bfgminer on each chili with a sharpie. then i just go to manage, highlight the low hash unit look at the serial and go fiddle with it.

Sounds good. If it's a junker let me know; I need to practice on some of these things and known blown trash systems would be halpful.

If it's fixed, pls post what it was; I'm thinking this is going to hit other people.

No obvious burnouts. No bulging capacitors etc.
I'm shipping it off today to Lucko. Then see what he can find, Maybe a simple fix, or fried.

I'm not set up to start accepting repairs, but I can say that this problem (fails of the 12 volt supply fuse, thank you for putting a fuse in) is probably due to a failure in the 12v-1v DC-DC converters. On the chili they use a cool component to do it (I need to find out what that is to backfeed BFL boards) on the BFL boards they use a 6 fet push-pull system. Fet fails, system crashes. Add unregulated 12 volt supply, hilarity ensues.

Check to see if any of those chips smells like smoke.

Hi Lucko
I was thinking of asking you if you could open a "Chili Hospital", but I thought you may be busy this week.

My only testing facility is a multimeter. Your help would be appreciated.

I can look at it if you can't figure it out...

My Chili is dead rest in peace Chili

Hashing along steadily for 27 days at 34+ Gh and generated 0.68 Btc sold at $571 yesterday.

Today it died, RIP.

Dead short somewhere on the board. (changed all the cables, 3 different PSU's, fans etc) It trips each PSU.

The ghost of Chili is in the room, it feels colder already.

Agreed on this diagnostic. While not running a chili, my jally with 5 chips picked up an extra 1.5gh from a real heat-piped heat sink square on all chips.

You can disable one in bfgminer and go looking for the unit with the lights off.

How do you determine which one among the 60 boards?
There is no led indication and the identify command in bfgminer does not work.
Thank you
 

When do you anticipate delivery to start?

Due to some excess market demand, we are going to reopen sales and do a batch 3.

If you are interested assembly of your chips, we can do that as long as the chips can be sent to us by Tuesday the 3rd of December. The price will be the same as the previous batch, at $350 plus shipping. Contact me through PM or at [email protected]
We will also have a quantity of boards available for sale. More details on that will come soon, but we should be able to satisfy some of the pent up demand.

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.

Is this still open for orders ?
