Yeah all this chatter about hooking up pc power supplies is a pursuit of the damned, for additional pain and misery. Just get real power supplies and be done with it.

I do not know how these units were designed, but let's assume for a sec they have a thermal cutoff. Then some of the sections may shut down if they get too hot. Inconsistent fan on your three blades could cause that. Laying them flat on a surface with no airflow to one of the sides could do that. Too close together, etc.

To determine if it is a hardware problem, swap the little board with the RJ45 connector between known good and suspect. Then swap the power board. Then swap the RJ45 cables, which can definitely go bad.

If you move a part around and the problem follows the part, you have a bad part. The only exception would be special handling of that part's IP address by the router. Obviously each of the blades needs a discrete IP and it must be in the addressing range of the router. They all came as 192.168.1.254, iirc.

I set mine to 192.168.1.200/201/202...

Note there is a reset switch between two pins, it reset back to default IP.

This is good advice, Though all three of my blades are exhibiting the exact same behavior so I don't know how to play them off against each other. I did however try to move the strongest PSU around them and it made no difference. I'm convinced the blades themselves have a reset timer built in. As if a condition exists that is causing them to re-start in an attempt to mine.

I am fairly certain it is not a heat issue, I have the three blades mounted about 2" apart vertically and I have a extremely strong blower blowing between/around and through all three. It is thousands of CFM. It is the style you would see at a store to dry off the floor after a long rain. I have to run it on the lowest setting otherwise I risk blowing the blades across the room! Wink

When I reach into the gale force winds, the blades are warm only. on all surfaces.

My 'gut' is telling me there is a connection issue causing my blades not to recieve proof of work/submission etc from the pool and they are auto-restarting. I am going to try to get into my router and make sure I open all ports (if they are not) and see what gives. I have a feeling these blades think they need to restart because they think they are hashing without reward? Are they smart enough to check for that and restart?!

if you dont mind setting up a linux box( or have one), or a linux VM on a windows machine. you could probably verify your theory with the latest versions of bfgminer which have the ability to act as a getwork proxy now, the proxy acts as a mining device to bfgminer so itll give meaningful info with -D 2>debug.log appended on the end. if you have any questions on setting ut up just gimme a hit

I'm curious, how do you infer blades were resetting? This would mean they would go back to defaults, which in turn would mean before the 'reset', they had their set IP addresses and user id/passwords, then they reset, and they have the default IP addresses and standard passwords.

Is that what you are saying? Obviously if that were so, there would be zero production because the blades are going offline as far as your system was concerned. Maybe you should post some of what the screen says?
