Increase bios limit of cpufreq

Jump to solution

Hi all,

I have a http://ark.intel.com/products/91755/Intel-Xeon-Processor-E5-2697-v4-45M-Cache-2_30-GHz Xeon E5-2697 v4 CPU, which is posted to have a max cpu freqency of 3.6GHz, which I cant seem to reach. I've fiddled with the bios options, plugged in the backup power supply, and done everything I can, but I cant get it to step over the 2.3Ghz mark.

my OS says that the:

cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_available_frequencies

2301000 2300000 2200000 2100000 2000000 1900000 1800000 1700000 1600000 1500000 1400000 1300000 1200000

And the bios_limit is:

cat /sys/devices/system/cpu/cpu0/cpufreq/bios_limit

2301000

Which Bios options do I need to set to enable 3.6Ghz?

Hello kevlarjacket,

I just wanted to share with your that this feature will be reached when need it, there is no option to turn it on or off. The maximum turbo frequency indicates the highest possible frequency achievable when conditions allow the processor to enter turbo mode. Intel® Turbo Boost Technology frequency varies depending on workload, hardware, software, and overall system configuration.

More information regarding this feature can be found here; http://www.intel.com/content/www/us/en/support/processors/000005641.html Frequently Asked Questions about Intel® Turbo Boost Technology

Amy.
