Hi, a couple of weeks ago we noticed that all nodes on our c6320 aswell on our c6220 are locked to 1.2GHz. On our c6220 we were able to bring clock speed on Intel(R) Xeon(R) CPU E5-2640 0 @ 2.50GHz back to 2.9Ghz by setting bios Option "emergency CPU ThrottlePolicy" do nothing. But on our c6320 there is no such Option bios and idrac are latest versions.  Bios: 2.16.0iDrac8: 2.83.83.83 CPU model on c6320 is: Intel(R) Xeon(R) CPU E5-2640 v3 @ 2.60GHz OS: Ubuntu/CentosWhat we've checked so far:  - difftrent kernel - diffrent OS - switched intel_pstate,intel_cstate,acpi_cpufreq driver - Set all options in bios and iDrac to performance - disabled cstates and c1e in bios - reset bios to default  - disconnected from power for 30mins  - played with all other cpu related options in bios   CPU Temps are fine at around 45°, power supplys both working, no errors in idrac log.  The Strange thing is that 2 C6xxx systems had the same problem on all 4 nodes. As i mentioned before on C6220 it could be fixed with bios option "emergency CPU ThrottlePolicy" do nothing. Does anyone has an idea how i can manage to get clock speed back to Normal?Thanks. 
c6320 clock speed locket to 1.2Ghz on all 4 nodes
