Thanks. Is that safe? Won't it start a fire?

No fire here so far.

Got the cable. Which holes do I plug it into on the PSU?

This should help...

Any news about batch 3? Are you still planning on auctioning off some populated boards?

Yeah, I need to get on that. I should be posting it up tonight or tomorrow.

I got to take a look at that little board last night.... I would be interested in leftovers from batch 3 :-).

Is it possible to flash new firmware to these using linux? (a rpi w/ minepeon specifically)
If not, can someone point me to the windows flashing procedure & files? Thanks

If I'm not mistaken, batch 3 has not been released yet.

To clarify I saw a board from one of the earlier batches (that I wasn't a part of)...

I wasn't trying to imply that Batch 3 had any released boards.. sorry about that :-)

Really happy w/ my chilis atm - bought a sunzi (6 chilis)

In my cold room ... they are clockin between 36-39GHs/avg ... freakin awesome!
My overall error rate at this speed is 7%
Power consumption @ wall - 1280W

Total avg hashrate: 225GH

Has anyone found a new *cheap* source for the Antec Kuhler Shelf? The $10 ones are out of stock:

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.

Earlier this week, I recieved 4x more Chilis from another forum member. The hashrates reported to me from the other member before taking delivery were 29-31ghs.  I asked for them without the heatsinks, since I already had 4x extra Antec Shelfs.  I used the above method again which I posted about before and I am now getting between 32 and 35 ghs.  Seems like it's quite an improvement, if I may say so myself!  

Also, one of my original 4 Chilis is acting very different than the rest.  It always shows 58-59C and it is my highest performing one at around 36.5 ghs.  Very interesting.

My original 4x are still getting between 34 and 36 ghs (and the one which runs at 58C has been running above 36.5 ghs for some reason)

Have you tried adding airflow on the undersides as well?

Wow, that is awesome! You must be keeping those chilis chilly.

Yes, I have 3pin case fans blowing onto them...

Please somebody upload the original firmware. After updating firmware, my chilis run slow.

[ChipGeek]

Please somebody upload the original firmware. After updating firmware, my chilis run slow.

How much slower?  How long did you let them run before deciding they are slow? 

When first powering on, they intentionally run slow then speed up based on temperature.

[agibby5]

Regarding the firmware, do you think it can be tweaked to increase performance any?  Just wondering since it'd be a huge benefit to those of us running these devices already!

Sorry it was due to cooling problem, not firmware. Now it runs 35GH/s and 38GH/s. Thanks!!

Yeah, I wish I could figure out whats up w/ that 11% hw error rate one. It wasnt that high when I tested these at the office. But these were not clocking anywhere near these speeds either at the office. So, maybe its just related to higher speed...or some weird seating issue happened during transport.

I wonder if he got lucky and got a good batch of chips.  They're all running cool. I have one that performs this way and it's getting almost 37ghs.  The rest are pegged at 70 and get between 33 and 35

Well the room they are in ... is like 50-60F =P
Oh, can chilis be safely "hot plugged/unplugged" on the power?

[GenTarkin]

Got a question, the temperature readout in bfgminer/cgminer ... is this the of the hottest sensor on the board? Or... a specific sensor...
