Some random thoughts on avalon 6 antminer s-7 and j4bberwock/finksy boards

Stable? I wish the S7 was stable. Every day I have to reboot a bunch of machines that hung either for a 30-second loss of pool connection or, well, just because they felt like hanging.

I bought a few of the early versions and they seem to hold well (above 30 days for most before a restart) but the later versions seem to have the issues

my batch 2 is  a simply outstanding  miner.

I can get .248 watts a gh and run the freq at 631 giving 0.0005% error rate 

this one was rated at freq 575.

my batch 1 sucks still sucks and is lucky to do 4200gh with 0.1255 error rate.

both still run

batch 2 for  8 months
batch 1 for  9 months

Ya I have a batch 2 and 7 that seem to run perfectly

I'm making some change at home and i will be using two 4K DPS breaking board with the DPS-2000.

Last time I red this thread I took a good look at all my cable and the breaking board and none was overheating then come the summer. I made some change two days ago and I had to change 5 cables.

2 was in bad shape with brownish yellow cables and the connector was also affected at the board side but nothing miner side.

So I should have added some extra air flow on the breaking board and it would probably not happen.

So now I have some brownish connectors on the board side. I don't see any modification to the connector form, even with the worst one. Just sucks to see that.

So beware and add some extra air flow to the breaking board if you're room temps is getting hot for a long period of time.

i have never had an issue with the 2880w boards except for 1 board and it was an early one ( green pcb)



the only sockets i have burnt were on neptunes but never on the breakout boards the green board was the only exception , i hang my psus out the end of the shelf slightly so the air can flow around both sides of the breakout board

with ur burnt breakout sockets id have to wonder if u had bad connections on the pci-e cable to socket or wire to the pin
