Found the solution.. (After formating my pc i did the usual tweaks in regedit) so i had a tweak that iv use in I3 computers to set the processor at its maximum.. but as i can see its not recommended for pc's with turbo boost cpu's
Computador\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Processor (word Start at 4)
Computador\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\intelppm Start 4
will put your processor at max speed all time.
