PM me some pictures of your wiring and cooling setup.

it was working ok for 3 days with the same configuration.

i have only 1 balde wirch is powered by 1 PSU , i think that should be enough.

Is this server PSU compatible with backplane and new blades?

Log-in to your router and make sure the Ip range is set to 254, My router only allowed up to 192.168.1.199. so I had to change it to cover the Blade.  What type of router do you have. I can try and help you set it up

Can you show me- What settings you have when you manually set the ip.
Did u also , set the primary Dns to 192.168.1.1

Well i got it working. The issue was that one of the windows network apps had to be enabled. Networking is not my forte. So i managed to change the IP on one blade and connected it to my network. it immediately found the proxy server and started chugging along.

There is a lot of stuff scrolling up the Proxy server window. This is Slush Proxy. I'm seeing some kind of Warning message, but it seems to be hashing ok, is this normal?

Hi,

I have a strange issue with my v2 blades.
They are new and this is the first time I try to run them.
The issues is that their hash rate goes up to 5Gh/s than falls back to 0 than up again but never above 5Gh/s.

I tried with mining_proxy and with bfgminer and with both it's the same behaviour.
BFG miner marks the proxy as sick.

I also tried using a different switch but same result.

I checked the voltage and it seems to be fine. The temperature is ok as they are in a server room with good air flow.
All chips are marked O.

Anyone had this kind of issue ?

Thanks.

I had to upgrade my Router. I had an old Dlink, kept droppring connection. Switched to a New Dual Band Belkin and works like a charm

My old setup: 3x Blades->3Com OfficeConnect HUB(!!!)->cable->TPLink Router->WLAN->Stratum Proxy->WLAN-> TPLink Router->Internet

Sometimes the connection between Blades and Proxy went down for unknown reason. Someone mentioned to keep mobiles with enabled WiFi/WLAN away or turn WiFi/WLAN off, followed that hint and all running stable!

Actual setup: 3x Blades->3Com Hub  ->cable->Stratum Proxy->WLAN->TPLink Router->Internet

Load on the network Blades/Hub/Proxy is about 3%-6% max, collision LED sometimes flashing.   

I would try upping the voltage in steps of .05 to a max of 1.25 to see if that brings the chips to life.

I see you have the clock set to low, or else it's forcing itself down. Make sure to set it high and then reset afterward, inbetween each voltage increase. When I was tuning mine, after every reset I had to wait a few seconds (10 I think) for the blade to put itself under load. I'm sure you're doing the same, but just a general reminder to use the voltage readings  while it's under load.

The only other suggestion I would make is to take away the 2 fans blowing on the faces of the blade and let the one blowing across do the work, unless they're all really low output, less than 55CFM let's say. 70+ CFM blowing air in a cross manner like that might cause too much disturbance and prevent good air cooling.

You couldn't tell my blades are under full load by touching them, they barely register a noticable warmth to the touch.

I mention this because I've noticed on the Gen1 blades, even slight warmth can kill performance. Before I changed my fan setup they were "somewhat warm" to the touch, but would sometimes be stuck around 5-8GH. New fan setup, and they're 14GH+, effective rate of around 11-12.
