The whitepaper we refer to is: Configuring and Tuning HP ProLiant Servers for Low-Latency Applications The main takeaway is to run with the "Maximum Performance" profile. You can also enter a special BIOS menu using CTRL-A from the RBSU screen. This allows you to toggle the "Processor Power and Utilization Monitoring" flag off. The recommended SLES (and RHEL) OS-level settings are also contained within the document. So I'm curious as to why you're interested in manipulating CPU frequency from the OS. I'm assuming you'd want the highest CPU clock speed during the periods of trading activity, so when would you require OS control? (We actually disable all OS CPU speed control) It looks like you're

I seem to remember a loader command to update the cache, can anyone remind me what it is?NB: I have an Intel Core2 Duo E7300 CPU, and would like to underclock/undervolt it to get some power savings, as I am running at less than 20% cpu most of the https://bbs.archlinux.org/viewtopic.php?id=96987 time, even with 720p content. I thought I would do the frequency stuff in the OS and do the undervoltage stuff in the BIOS (unless someone can tell how to undervoltage in the OS).Thanks.

The acpi-cpufreq module offers voltage scaling in addition of frequency scaling. You should use that instead of p4-clockmod, if possible.I had been following that link ..Thanks,B Last edited by bmentink (2010-05-12 02:07:09) Offline #4 2010-05-12 04:07:59 bmentink Member From: New Zealand Registered: 2009-08-23 Posts: 385 Re: cpufrequtils module won't load [SOLVED] An update:I read somewhere that I might need to update my bios to get ptable support for my CP

FATAL: Error inserting acpi_cpufreq (.../acpi-cpufreq): No Such Device After upgrading my laptop from FC5 to FC6, I was getting the above message during the boot sequence. When I looked at the Red Hat bugzilla for this problem, I saw that someone had solved it by installing the correct kernel version. When I looked at the kernel I was running, I discovered the the upgrade had installed the i586 kernel instead of the i686 one. Wh
