HP ML110 G4 Windows Server 2003 and SpeedStep

I am using a new HP ML110 G4 with a Xeon 3040 processor and Windows Server 2003 Enterprise SP2. OS is installed with all drivers but the SpeedStep technology does not seem to work though enabled in bios. The cpu is alway running at 100% frequency and is not afflected by any of the options available in the power managment. Can anybody tell me how to enable SpeedStep or is this some kind of bios bug?

Speedstep is only a technology offered in mobile PC processors, not servers. What is the name of the option that you enabled in the bios?

Hello Ryan, the option is called "Enhanced SpeedStep Technology". Intel has put this feature also into server processors (http://www.intel.com/cd/channel/reseller/asmo-na/eng/products/server/processors/3000/feature/index.htm)

Hmm, seems you are correct!

This article may help then:

Different ways to determine CPU speed in Windows XP or in Windows Server 2003

Also found this on Intel's site:
http://www.intel.com/cd/channel/reseller/asmo-na/eng/products/box_processors/desktop/proc_dsk_p4/technical_reference/203838.htm

From the instructions on Intel's site, if you have "Always on" power profile turned on in Windows control panel, it turns off Enhanced Intel SpeedStep. I'd start there and make sure that you have the profile "Minimal Power Management" selected.

I already tried the different power management profiles including "Minimal ..." but with no success.

Have you installed the latest BIOS update and the latest Chipset driver?

BIOS:
http://h18023.www1.hp.com/support/files/server/us/download/27204.html

Chipset:
http://h18023.www1.hp.com/support/files/server/us/download/24999.html

From what I can tell it's embedded support much like how you didn't need a driver for Hyperthreading.

Newest bios is installed as well as the chipset driver (i also tried the new ones directly from intel.com).

If you type at the cmd prompt powercfg /query does it show adaptive for processor throttle? AC & DC?

Yes it does for AC and for DC.

Re: HP ML110 G4 Windows Server 2003 and SpeedStep

I'm out of ideas...Only thing I have left to suggest is to install CPU-Z and monitor the CPU before and after turning it off in the BIOS to see if there are any changes.

I already did that too but the freq did not change. Thanks for your help. The best thing seems to be calling HP for direct support.

Please reply if you find a solution, I'd like to know what fixes it.

Do you have a option in the bios to enable or disable Dynamic Power savings mode?

As from what i seen on the higher range proliants the 3040 is qualified to work with Dynamic Power savings mode, but it does not mention the Ml10G4 this could be a limitation of the systems bios itself...

Your best bet would be to give hp a call just to double check it is supported on this system.

Does this system have an ILO port?
there you may find under "virtual devices -> power regulator" the option you look for

attached an example, but this specific model does not yet have this option yet.

No, this server does not have an ILO port. The SpeedStep option in the bios is the only option for any kind of power saving.

Re: HP ML110 G4 Windows Server 2003 and SpeedStep

Some news: I checked the power consumption of the system with an external power meter and notified that under a cpu load of 50% the consumption rises about 20W. So it seems that SpeedStep actually works but Windows isnt able to recognize frequency changes on this particular processor without external software. With the latest version of a program called cpu-z i could determine that the multiplicator changes from 6x to 7x under cpu load.
