By the way, some heat sink notes:
Unit was hashing at about 35gh, water cooling block on top (sedion), been running for months. Finally decided to pull the sink and put some authentic artic pads on the units to speed things up.
Back together, speed is 5gh. Um....
Took apart, put artic silver on block and on each chip. Smoothed out, put together, 15gh. Took apart, put together, 20gh. Took apart, smoothed silver on two chips, put together, ZILCH. Board must have shorted.
Sigh. Started over, cleaned board, cleaned between chips, over and over, cleaned plate, put artic silver in a thin amount on plate, smoothed with razor blade, nothing on chips, put together, 35gh.
I give up. :-)

How much money would it take to get the z-link finished? BTC0.25? BTC0.5?
Ok, i will try today.
I have. 2 chilli for sell

I've seen screenshots with stat readouts for the individual hashing engines. Is this possible with the chili? My hashrate is only 29GHs right now, and I have a suspicion it's got to do with the coverage of this heatsink, but the easy way to tell would be if a bunch of engines are down on a chip or two.
@Mr Teal ?
Any help ?
If it's running at 70C and 15GH/s, your issue is likely the heatsink wasn't properly mounted when you changed the thermal paste. Reseat it. Any help ?

Right now is about 70.
Is is about 65-70
But when i use the firmware flash to check it show 29-30gh
then i do the power cycle.
Then i power it up a gain only run 15-16gh since 3 days now

My only run at 15-16GH ?
i just replace the thermal paste.
Any suggestion to fix ?
Did it just start working at 15-16 after you replaced the thermal paste?i just replace the thermal paste.
Any suggestion to fix ?
What temperature does it read at that speed?

A big thank you to Mr. Teal for fixing my board. Not only am I happy with my boards, but I am especially pleased with the fantastic customer service!
Your heat sink might not be on right or contacting everything. The code will slow the chips down which will really cut the temps.

I will try this. At first it seemed to be the vregs limiting it, as it throttled after the chips hit 65C at 32GHs, but I wonder if one or two of the chips aren't making good contact because of the flexing from shipping.
does it necessary to send my BFl chips, or it is possible to buy those too ?
I just got my chili, and have it hooked up and running, but it's only running at 27.5GHs, and the temp isn't going higher than 60C, when these chips are rated for 70C? I have another fan blowing on the vregs, which have heatsinks attached.
Are you using a backplate? I've found that having something on the back of the board for the sake of stiffness ensures that the board doesn't flex so chips can't pull away from the heatsink. At that speed it sounds like a cooler contact issue to me too. My water cooled Chili ran around 33GHs @ 61C but when I added a fan over the VRMs it went to 38GHs @ 69C.

Try re-seating your cooler, it can help.

Restarts are part of the gamble. Only time will tell.
I have a theory that the Chili was designed and prototype tested in an "American Air conditioned summer workshop"
Now that they are out in the wild (of the rest of the world) There are some "exceptions to the standard" being found.
The next firmware release will probably bring things back on track.
If we are still hashing them in the coming summer then they will have had a good testing cycle.
The unfortunate reality is that they will be way out of date by then ( in 6 months they may be the "graphics cards" of the asics)
Such is the speed of development of mining hardware.
Yeah this is the ultimate example of diminishing returns, with that said I'm very happy with my chilis they go days and days with out restarting including the Lucko boards(pleasantly surprised). And yes I do miss the 2 I sold you...
The 2 MrTeal Chili boards are now in my remote cluster (12 boards) (the boards I can trust) managed by 2 rPi's, the cluster is split into 2 parts, for further safety.(hash rate is 417Gh at the pool)
As you say they are stable and reliable. My only concern is that with the rPi donations turned on, the pool switch does sometimes cause a crash.
At home I have the last 4 wobbly boards that need the supervision of my mini desktop pc.
Under windows they run most of the day and usually manage to restart themselves without intervention.
On the rPi if they crash then they stay down.
The hash rate for these 4 is 126Gh at the PC but only 87Gh at the pool, so they are restarting and crashing a lot.

It's a corsair cx500. I just cam home on my lunch break and was able to get it to turn on. I'm sure it will stay on for a couple hours but can go down at any thime. Then I will be unable to get the psu to turn on again for a long time. Thx again.
Check the voltages on the PSU while it's running. It's a group regulated design, so if you're pulling enough current on the 12V line without a load on the 5V line it's possible it's shutting off due to overvoltage on the 5V line.
Just out of curiosity. I have been running the single chili off a single pcie 6 pin coming from the PSU would that be a problem? I can try and find a dual 4 pin molex to 6 pin pcie adapter if needed. Anyone think this might be an issue? Still up and running since my last post. But i am sure by the time i wake up tomorrow it will be down. It has not stayed up more then 12-16 hours yet. I would ideally like to run both chilis off 1 500 wat supply if I can. Doesnt matter if its on the pcies themselves or if I need to get adapters. Please let me know. Thx!
Thats what ive been doing. O well new PSU comes in today. Will test more when I get in from work.
So got both of them hooked up to a 500 watt thermaltake and theyve been going fine for about an hour. I didnt realize this psu had 2 6+2 pins on one rail and then an 8 pin on other. After testing both chilis on the 1 rail with the 6 pins. I determined it was a bit to hot. So I chopped off the 8 pin and connected a 6 pin to it. So far so good! If it makes it thru the night I'll be a happy camper. Thx for the input guys!
