what temp is needed for the board to cool to startup?
I have em in my garage the board in about 40'c and the 7th led never went off.
(my garage is a little bit warm have 15KW miners in it)

Set a free standing fan to blow onto the board and cooler.

the 15kw made the ambient is greater than 30c. no help, firmware is the only way to slove this, I nailed them in the racks and the racks are huge cant move.

Place a sealed ice pack on the unit to cool it down and see if it starts.

Hi xselam,
As I said in my email, we'll get you a firmware fix for the not starting properly in 40C ambient, and then roll that into the next general firmware update.
Thanks

Here is me thinking my ambient of 23c is too high.
When I open the window and reduce to 0c to 5c the family complain!
Where are you at?

I have 1 miner that will not finish the boot sequence. it just keeps flashing the 7th and 8th leds. i have turned it off for several hours and tried it again still no luck.

Is that batch 1 or 2?  There was a bug in early batch 1 boards that was fixed half way through batch 1.

Edit: Before someone asks, the bug was due to new behavior in the revision 2 ASIC chips and was fixed (a workaround) with new firmware.

I've got two units which won't go through the startup sequence; the 4 right most lights stay solid. Does anyone know what that means when those lights stay on? My other 15 units work perfectly.

Send me an email, I'll help you get those set up and running.

I sent you an email with a better description and pic. Hopefully you can figure out what's causing this. Thanks.

I have 1 unit have the same problem.

I would recommend upgrading the firmware.  Details here:  https://bitcointalk.org/index.php?topic=304250.msg3531327#msg3531327

This is why I went from garage > warehouse > bigger warehouse. Heat is nuts.

More like garage > warehouse > divorce for me.

I updated the FW on that miner because it kept failing out after running a while. and when i shut down bfgminer and brought it back up to bring in the last miner again 3 others started getting 100% errors.

EDIT: now just one has the 100% error issue. it is the one with the updated FW that was having problems before.

EDIT 2: fixed!!! it was a power supply issue. the one failing and the other 2 that failed were all top performers and were causing the power to exceed the power supply's limits. i swapped some units around to get better power balance and now i am hitting 440gh/s on the group of 13.

Anybody have any pics of their Chili setups?

[jelin1984]

Any news or updated firmware for chilli board?

[i3luefire]

if one of my miners is showing temps of 37c and 57c is that a bad sign? it is still hashing at 37gh though

So here's a quick picture of what I've (on an unfortunate post-Halloween sugar bender) named my "Tower of Power" cooler.
Basic setup is two of the $10 Antec Kuhler Shelf coolers, with a 2" #8 screw connecting the two coolers. There's also two press on heatsinks on the VRMs.



The bottom heatsink just has some Kapton tape and a little thermal grease on it, while the top cooler is just using thermal grease. Using this setup there is no board flex at all. The thermal grease is just the Antec branded stuff that's inside the box.

This took one of my units from 29 to 36 GH/S. I like it!

[xselam1988]

what percent of HW you are getting? I have 20units around 5%-10%
1 unit at 15%. and I have one unit wont boot? 1-4led is constantly on.
