Odd Mhz on CPU


Recommended Posts

Why is CPU not booting with the same frequency in OSX every time? Sometimes when it boots it has 3.66Ghz as native MAX and sometimes it has 3.70Ghz. What could be the reason? Anything to real bother about? Anyone else seen this? its ivy bridge Xeon E5 with SSDT from ssdtprgen all turbo modes and idle modes working.

Log seems OK. Nothing stands out. Maybe its the base frequency that is not the same all times.....ie spread spectrum or something...
