[H] Greg>> six core turbo mode

[Winterlight]

I have yet to over clock my six core Ivy Bridge 4930k. It is rated at 
3.4 GHz with Turbo at 3.9 GHz. However, when encoding with 100% on 
all 12 cores I am running at 3.54GHz Turbo as stated in Task 
Manager... so why doesn't it rise to 3.9GHz in Turbo when it is 
running flat out like this.

FYI There is plenty of quality power being fed into the CPU via the 
P9X79 WS motherboard and an abundance of  large radiator push pull 
liquid cooling for the CPU.
