In our office we have two Dell PowerEdge R310 Servers which have Xeon X3430 CPUs and should run at 2.40 GHz. Both have Windows Server 2008 R2 Enterprise installed. Unfortunately one of them is operating at only 1.20 GHz even at full workload!

see here

What should I do to utilize the full CPU power as shown here?

    What did Dell support say when you called them? It could be a number of things, including cooling. – Tim May 17 '17 at 21:22
  • I didn't because our support period has finished.But I am sure that its not a cooling issue. – Analoggen hacker May 17 '17 at 21:31

    @Analoggenhacker How are you sure about that? Do you have thermal data to back up that claim? – EEAA May 17 '17 at 21:34

    You should check the CPU core temps, either with software or in the BIOS. I wonder if you can restrict CPU performance in the OS. – Tim May 17 '17 at 21:36
  • check your power plans in Windows and the Bios – TheCleaner May 17 '17 at 21:44
  • @TheCleaner That looks promising! let me check. – Analoggen hacker May 17 '17 at 22:05
  • @TheCleaner I checked the power plan on OS,and found a custom plan which cooling policy was set to "passive",now i changed that to "active" and then reboot the server,but that did not fix the problem.. – Analoggen hacker May 17 '17 at 22:17

  • As I said earlier, check the temperatures when the server is working hard. I use [Open Hardware Monitor](http://openhardwaremonitor.org/) but Dell may have their own utilities that does this. – Tim May 17 '17 at 22:33
  • @Tim temperature is normal,46 max on 100% cpu load. – Analoggen hacker May 17 '17 at 23:19
