Disable C-State

lelakata — Mon, 26 Jul 2010 17:08:19 GMT

We would like to disable the C-states' of our Virtual Servers running Hyper V. We have tried to go in to the BIOS to disable this but are unable to locate the setting in the BIOS. Our virtual servers are ProLiant DL380 G6 boxes running BIOS Version/Date HP P62, 3/30/2010.

Any direction you could provide would be appreciated.
Thanks

try this if it helps
1. Enter BIOS by pressing F9 on POST
2. Navigate to "Power Management Options" => "Advanced Power Management Options" => "Minimum Processor Idle Power State"
3. Choose "No C-States"
