Kernal-Processor-Power Error

[Jduehmig]

One of my DL380 G7 servers recently started logging the following error:

Log Name:      System
Source:        Microsoft-Windows-Kernel-Processor-Power
Date:          12/8/2012 12:25:44 AM
Event ID:      37
Task Category: (7)
Level:         Warning
Keywords:     
User:          SYSTEM
Computer:      server1.internal.com
Description:
The speed of processor 17 in group 0 is being limited by system firmware. The processor has been in this reduced performance state for 0 seconds since the last report.

Following instructions I found on-line, I ran the Support Pack and updated all drivers and firmware.  I also went into BIOS and changed the “Minimum Processor Idle Power State” to “No C-States”.  The error has since gone away, but I am wondering if the error was truly an indication of performance issues.  I had a number of users reporting slow performance on an application and I'm trying determine if the changes I made will have any impact.  I also have an issue with NUMA spanning which I hope to resolve by adding additional RAM.  Does anyone have any thoughts on the impact of these two issues?

Thanks,

Joe

Anyone?  Does this make sense?
