Hi.
Its me again looking for help with my U3  

I have been getting a pretty decent average from my two U3 for some time.
Most of the time 115/120GHz that is pretty good I believe.

Since monday, average dropped to 100GHz most times even lower.

I changed USB cable also the same result and many reboots (computer and u3)
I wonder if maybe a chip is dead? could it be?

They are been cooled and I run default comand in Windows 7 has follows



WU value is always lower than the other, before I thing they were pretty much the same.

Is there something I can do to get better results has before although nothing changed?

At the end of the day it makes quite a difference in my earnings with this lower average.

Thanks in advance.
