Hi,
I'm in a summer install of about 400 new core i7 computers in my campus. I had time and tried x11 cpu mining on multipool thru a mining proxy , on about 150 computers, and go up to 30/40 MHash. (and i don't seen that the aes option is default disable in the bios

)
Now need some advice with such a red, what's the better ? continue use a multipool , build a P2P Pool, solo mining ?? Going on x13/x15 other news cpu coin ?
Thx for any advices!
X11 is not profitable most of time as good as x13 and i guess x15 will be replaced by x13 soon
you should better use multipools to earn more and to increase performance you need to apply some optimizations in these pcs.
they should not go sleep. Check google for tips
