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? -- View this message in context: http://freebsd.1045724.x6.nabble.com/Bogus-turbo-mode-with-Intel-R-Core-TM-2-Duo-CPU-P9700-2-80GHz-tp6147461.html Sent from the freebsd-stable mailing list archive at Nabble.com.
