Re: Intel Speedstep Windows 7 12
Alfonzo Liebenstein
i checked my BIOS and i just disable the intel speedstep, actually it helped a bite. my CPU went to wrok on 2.3GHz but with no turbobost (until 2.9GHz). but for mean while its better for me like this, but i wish to find an answer here.
Well as dell website offers drivers I installed. There is no chip drivers on dell website. Even sound driver dose not work, I work on driver from Microsoft update, the same for wireless driver is sux too. But all drivers are fine. Dell offers video driver, sound, WiFi, Wan, another other dell software. Drivers like win 7 dell dose not offer
8.1 isn't supported on this system, but I suspect another cause - this is a relatively old system now, and if it's never been cleaned out (i.e., dust removed from the heatsink and new thermal compound applied to the CPU/GPU heatsinks), it's well past time for that. The system is likely overheating and causing the throttling you're seeing.
well i give up, i just installed Win 7, all drivers are fine, the internal parts are clean, i just cleaned it not so far from now, temperature are fine dose not go above 60, 2 minute on windows logging the CPU works fine, but it goz down after that. i checked with the intel utility it gave me this info:
I have a Lenovo Thinkpad E15 whith Ubuntu 20.04 mounted on a NVMe SSD 1TB, in dual boot with the original Windows 10 Pro, and everything went well.I added some software and external hardware. Now I have this error during the boot with Ubuntu:
AER: PCIe Bus Error: severity=corrected type=Physical layer (receveir id)
AER: device [15b7:5006] error status /mask=00...01/0000e000
AER [0] RxERR
and the Ubuntu's boot is possible only with Ubuntu's recovery mode.
have led me toswitch off in the setup of the computer Lenovo E15 the Intel SpeedStep Technology:
SETUP>CONFIG>POWER>Intel SpeedStep Technology> [On]-->Off
and so, the error disappears and the boot of Ubuntu 20.04 go normally.
It follows, from all this, that there is a partial incompatibility betweenIntel SpeedStep Technology and Ubuntu 20.04here resolved with the switch off in the setup of the Intel SpeedStep Technology,so that the community knows an incompatibility and a practical solution found.
First af all, following the directions of David, according to
-there-a-way-to-disable-intel-speedstep-steppings-on-an-ubuntu-server-using-a
I used these commands to read and change the status of the cpufreq's gestion in Ubuntu:
But the most important page seems to me to be:
_frequency_scaling
it explains with clarity and completeness the CPU frequency scaling and the troubleshooting.
Especially for the IBM/Lenovo Thinkpads refers to thinkwiki for more thinkpad related info on this topic:
_with_CPU_frequency_scaling
This page at the end says:
Add "processor.ignore_ppc=1" to kernel boot command line or run
$ echo 1 sudo tee /sys/module/processor/parameters/ignore_ppc
This allows to disable BIOS frequency limit, but can be cause the computer to malfunction if its power consumption is higher than 65W and you are running off a 65W AC power adapter with no battery installed.
