Topic: The Chili – 30+GH/s BFL based Bitcoin Miner Assembly - page 32. (Read 137904 times)

Can someone respond to my question about the temperature readout shown in the mining software? Is it the hottest sensor on the board or a specific sensor?

anyone try chaining these things yet?  I have 10 of em and am just wondering if the z-link chain is working and how I would go about connecting all ten via the pins.

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

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

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.

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

Have you tried adding airflow on the undersides as well?

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

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)

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.
