cgminer is stopping work because one of the cores is too hot. I find that will happen if I haven't done a good job of mounting the heatsink; I'll see most of the chips sitting at 60-70 and one will shoot up to 100. The back and forth with cgminer is something we'll fix in a FW update, but the root cause is bad heatsink contact.

Will look into it but since reported temperature starts at 35 and go to 66 I don't think this is it... Unless we don't see highest temperature reported...

Replaced thermal pads... And problem fixed... But why I didn't see this hi temperature reported in cgminer? And got speed for 37.2 to 39.8

Is there a way to show all the chip temps? To show consistency of overheat?

Don't forget to cool the Mosfets. My core temp rose from 52c to 70c and hash rate went up from 32Gh to 37Gh (unfortunately the power draw goes up as well)

Remember that you want your cooling solution to give good force pressing the ASICs to the heatsink (force is the red arrows, BTW) without doing so asymmetrically which will bend the PCB and give bad contact on the center ASICs.

BAL 0 is Chili, BAL 1 and 2 are Coinado and Cointamination (no we didn't get it working with new chips it runs with samples)

BAL 0 is Chili, BAL 1 and 2 are Coinado and Cointamination (no we didn't get it working with new chips it runs with samples)

Most likely not all your chips are making contact. Had this problem myself once or twice while trying different coolers.

There are many causes mentioned in the thread but it seems to me most revolve around no backplate or uneven chips. If you're using TIM try adding a small amount of thermal grease between the TIM and cooler.

If you're not using a backplate then over tightening bends the board away from the cooler base.

I have backplate and this is not hot restart... I can just plug it in and start cgminer. I get it every time. And it gets cooler when it runs... So no it must be something else... Error reporting temp?

Overheat at startup then cooling and hashing later. The time scale is only 41 seconds from first flag to clean hashing. It does prove the cooling is working.
Has anyone else looked this close in the startup log?
Can the miner be made to display the chip number, it almost looks like first hash is failing on each chip (9 fails) then starting correctly when the cooler is settled down.

BAL 0 is Chili, BAL 1 and 2 are Coinado and Cointamination (no we didn't get it working with new chips it runs with samples)

Most likely not all your chips are making contact. Had this problem myself once or twice while trying different coolers.

There are many causes mentioned in the thread but it seems to me most revolve around no backplate or uneven chips. If you're using TIM try adding a small amount of thermal grease between the TIM and cooler.

If you're not using a backplate then over tightening bends the board away from the cooler base.

I have backplate and this is not hot restart... I can just plug it in and start cgminer. I get it every time. And it gets cooler when it runs... So no it must be something else... Error reporting temp?

Mr. Teal,

Any good news on how the rework went?

The boards are back at the assembly house, and the good news is that the pads are much better. We have a couple where the second pass of the air knocked some of the mask off between some pads, but not enough that it will affect any customer's boards.

Where can i find the latest firmware for the chilis? I have one that won't start hashing and is reporting to cgminer as a BAJ instead of an ls. I figure it was a bad flash or something stupid like that as it's brand new.

I try identify the form factor of the USB connection on the board.
Is it mini USB .... or micro USB?

one4many

It's a 5 pin Mini-B.

Thx ... this is just what I needed ... need to order a few ... still prefer to use chaining ;-) If it would have been ready.

Nice. That's what all the other USB miners I have use *except* for my bitburner which uses a micro. I much prefer the mini-style.

Put the TIM against the chips and added grease on top of the TIM. The grease comes in contact with the base of the heatsink, not the chips.

I was trying out different coolers last night and noticed something about the chips. The chips aren't just at different heights but are slanted in different directions.

They are slanted so much that the fuji TIM wasn't thick enough to make up the difference. For my first setup I applied Arctic Silver on top of my TIM and reached 36 Ghz. On my subsequent tries with just the TIM I was topping out at 29 to 30 Ghz. When I took the coolers off and looked at the TIM I could clearly see how uneven the chips were. I put Arctic back on top and I was able to get 36 Ghz again.

My thoughts are add some grease to your TIM or add a second layer of TIM to thicken it up.

I had my suspicions on this... the first time i unmounted my cooler and looked at the heatsink surface... in the right light I could see the outline of where the TIM had pressure on the surface. A couple spots looked like there might be less contact but not congruent with where board flex would have it... like the ships were not level.

So you are saying you put TIM on the chips... then paste on the TIM? So paste to the cooler base? Or do you mean paste on the chips, then TIM on top to cooler base?

To answer the questions.

You will need a power supply with a 6 in pcie
You will need a Higher end CPU cooler or GPU cooler.

I have been having very good luck with the dual antec kuhler shelf setup. This also makes a nice stand for the card. I have also been having very very good results with the corsair H60.

The cards HAVE to have a backplate,or they will have trouble booting (blinking or solid lights).

The boards will still connect but not hash in this state. It is poor contact or poor cooling (same thing).

The boards flex easily and even if you can not see it, it will make your board
1. Not boot, blink
2. Boot , throw a high hash rate but all errors
3. Hash slowly.

More detail please...

TIM or paste on chips?

TIM or insulator and paste on the bottom?

Hashrate using the Chilibug setup and the dual shelf setup?

1,2 and 3 are not 100% correct... I want more hashes... but I am 33-34 GH/s @ 70C with only the Arctic Accelero TT II no backplate using just Fulpoly TIM on the chips and thermal adhesive + mini heatsinks under the chips and VRMs.

EDIT: and where did you get an H60 for $32?

With extra cooling ABOVE the mosfets, I gained another 5Gh up from 32 to 37

I was trying out different coolers last night and noticed something about the chips. The chips aren't just at different heights but are slanted in different directions.

They are slanted so much that the Fulpoly TIM wasn't thick enough to make up the difference. For my first setup I applied Arctic Silver on top of my TIM and reached 36 Ghz.
