So there is no overclocking in gen2, that rules OC out.
Take note, are blades switching servers every hour or so?
In blade config, input one proxy server address to the proxy you want it to go and for second proxy give it a non-existent IP address on your network. I have had gen2 switching constantly and would lose hash rate because of that. I am now using a real proxy and 1 fake ip address like I explained above and my blades have been running for over a month no problem.
EDIT: Better yet, forget the proxy, run BFGMiner and it will be so much more reliable.
It's a blade how would running bfgminer help anything?
Latest BFGMiner can control blades and work like a proxy, so in that case you can get rid of the slush proxy altogether.
I thought I have the latest bfgminer. any clue how to set that up?
Here's an example;
Create a new instance BFGMiner and use something like following;
C:\asics\bfgminer.exe -o http://btcguild.bitmonsters.com:3333 -u user_blade5 -p xxxxx -o http://stratum.bitcoin.cz:3333 -u user.blade5 -p xxxxxx -G --http-port 8015
In your blade config use the following;
Ports: 8015,8332
Server addresses: 192.168.1.21,192.168.1.113
8015 matters, you need it matched with BFGMiner config. 8332 doesn't matter because it will be pointed to a fake non-existent BFGMiner instance.
Change first server address to your actual new instance of BFGMiner. Point second IP address to something fake, non-existent.
Restart blade while new copy of BFGMiner is running. Change the obvious settings like pool address, username and passwords. The "-G" will exclude any GPUs and "--http-port 8015" is where BFGMiner will look for a blade.
Try this setting and if your blades hardware is ok I don't think you will have any problems. I've been running the above setup for quite some time.

Ugh, slushy you need a freaking "withdraw now" button...
Change your threshold to 0.01 and you'll get withdraw now effect.
