Hi Guys,

Need some urgent help,I have a - Proliant ML570 G2, running Windows Server 2003-Std Edition blue screening very often.today it has BSODed 3 times. I did try to Debug and it points to a driver - intelppm.sys. I have no clue about this driver. Did search Google,got some hits for Virtual PCs(this server is not a Vitrual Server).No one is talking about a 2003 Server blue screening because of intelppm.sys.

Am pasting the Dump analysis here. Please help me out.

VAL - MCi_STATUS register is valid
Indicates that the information contained within the IA32_MCi_STATUS
register is valid. When this flag is set, the processor follows the
rules given for the OVER flag in the IA32_MCi_STATUS register when
overwriting previously valid entries. The processor sets the VAL
flag and software is responsible for clearing it.

UC - Error Uncorrected
Indicates that the processor did not or was not able to correct the
error condition. When clear, this flag indicates that the processor
was able to correct the error condition.

EN - Error Enabled
Indicates that the error was enabled by the associated EEj bit of the
IA32_MCi_CTL register.

PCC - Processor Context Corrupt
Indicates that the state of the processor might have been corrupted
by the error condition detected and that reliable restarting of the
processor may not be possible.

Please assist


Thanks in Advance

Jay.

Intelppm.sys is the CPU driver. I've had the same error on my system (AMD), the solution was to uninstall the CPU driver.

The AMD CPU driver is only required if you use Cool 'n' Quiet (power management), if you uninstall it, Windows will use it's own driver. I'm assuming that Intel is the same, you only need the driver for the power management feature (SpeedStep).

Hi Peter,

Many Thanks for your suggestion. Would like to confirm that-Disabling this driver will not affect the server in no other way other than power management feature (SpeedStep)


Regards

Jay
