Hello, 

Since I'm running this CPU, I've noticed there is additional
field in supported frequency (under heavy load)-

dev.cpu.0.cx_supported: C1/1/1 C2/2/1 C3/3/57
dev.cpu.0.freq_levels: 2801/35000 2800/35000 2450/30625 2133/23888
1866/20902 1600/15000 1400/13125 1200/11250 1000/9375 800/12000 700/10500
600/9000 500/7500 400/6000 300/4500 200/3000 100/1500
dev.cpu.0.freq: 2801
dev.cpu.0.temperature: 67,0C

as far as I know, the +1 MHz mode is a turbo boost factory 
overclock, however this CPU does not support it. Anybody knows 
what's going on? 

I've previously had T9400 (2.53 GHz), there was no such thing listed 
and it was running slightly cooler under load, despite having higher 
TDP (however P9700 is a lot cooler when idle, as expected).

Still, I don't think it is possible it's actually being overclocked?
