hello martyn,

I have rented your rig for the last 12 hours. I am very satiesfied about the hash rate, but I hope you can help me out . I have also a rig with 12 gridseeds but the hash rate of my rig in the pool is the half of the rate what i see on my miner.  I am using a windows 7 dual core with 2 GB and windows 7 64 Bit.  I have configured cgminer 3.7.2. Do you have some tips how to solve this.

thanks in advance
