Dogie, my tube came without the sheets of thermal compound, do you know what I can use instead ?

They're only strictly required if the hashing boards are damaging and so would be shorted by the aluminium heatsinks.

I used thermal paste (MX-4) and I think it's working well.

But after some time some hashing some "." in the chips are appearing.

They don't appear when the miner is restarted, they appear a while after.

Do you know what can be causing this ?

I'm using a Corsair 850W, maybe the PSU cant handle the Tube ?

Which 850W?

TX850W

Try just two boards at a time, so that way you know you're not maxing out the PSU capacity wise or the cables. Use all 4 PCI-E cables. Then swap over. If you're still getting .s appearing after time, its heat related.

If no .s, try 3 boards with 1 PCI-E cable each. If you get .s now, you need to get some 2x molex to PCI-E adapters to help reduce the cable loads.
If no .s still, it means you were maxing out the PSU capacity wise and you'll need to get an additional PSU / larger PSU.

Now the tx850w is powering only three boards and a cx750m is powering one board (and one avalon3 290 module).

It's much better now, it really was a power issue.

Thanks.
