This is a network at work. 10.x is a non public network like 192.168.x and 172.16.x
You don't use 192.168.x on work networks unless your IT Staff are buffoons. It makes it easier to type and recognize DMZ with 10.1.x 10.2.x etc isolation. I am pretty sure these are also plugged into the same switch, but I may be wrong.
If not in the morning I will get them on the same switch and then also test it with a 650watt power supply.
Ah, that explains that IP range.
The way I see it, you have two possibilities: 1. A bad Blade. 2. Some wonky network setting preventing the proxy from working correctly. You have tried different proxy's, multiple proxy's, two different power supply's and I'm guessing you probably have entered all your configurations in multiple times...there just isn't much left to these blades.
Before you give up and send that blade back, I'd try running off a proxy outside of where you work and have the blade connect to it and see if it make any difference. I tested my blade (that is up at my shop) and I ran it off a proxy I set up on my home PC. My blade still ran fine off the other proxy.
Ok I connected this up to a 575 watt power supply. there is no difference as I already knew since the 375 supplies more than enough current. It's sitting at 72% efficiency 6800mh/s for 45minutes, I call this no difference as it varied 6100-6500 on the 375 and +300mh/s is garbage to the missing 3000+.
no connectors are getting warm which is a sign of a poor connection so there is good connections, aka it is getting all the current it wants without a problem of high resistance.
I have a box fan blowing on it on high in a cooled server room. the blade both sides are mildly warm, the block eruptors in the same air are hot. so this blade is not over heating, it is getting all the power it needs and more than enough air flow. I have to conclude it is shot.
I changed the proxy ports to 8333 and 8334 restarted the blade. now I am sitting at 61% per usual and 5300mh/s aka the 575watt supply or a 375watt makes no difference to how well this works.
I am watching the 2 proxy screens....
This will get a ton of work then sit there sit there sit there... then get a ton of work from the other proxy or sometimes the same one but mostly flips...
i rebooted the blade and now its back to 6700... so odd 41minutes in and its settled to 5800 worse than when powered by 375watts
