Have kept an installation of openSuSE 12.2 updated on an HP Pavillion Slimline 7520 with an AMD Turion 64 ML-64 single-core CPU rated at 1,800 MHz. Recently (a few weeks ago) it slowed. The “My Computer” icon on the desktop (which I miss in 12.3) shows the full clock rate at startup (as does the BIOS initiation screen), but then it slows to 800 MHz. I’ve looked for power settings in the BIOS (nothing there) and in “Configure the Desktop” (also nothing other than in the Power settings where it is configured to “run as if on line power”. Just updated the kernel to 3.4.84 (or was it .86?) and the behavior is the same. Compared to the original IBM PC I should be grateful that the CPU runs at 800 MHz, but I’m not. I’d like to get it back to 1,800 MHz. Suggestions appreciated.
This is normal behaviour IIRC
Put it under load and it will come right back
Is that what you are missing in 12.3
For a time I thought the change in clock rate was normal but then noticed that even under load the rate stays at 800 MHz. I watch the “My Computer” display stay at 800 while the CPU utilization widget in the panel shows a solid 100%. The slower response of the applications seems to confirm the clock doesn’t rise to 1,800 MHz. On this HP machine ksysguard shows only the memory utilization; the CPU usage and network windows stay blank.
Each of my Duo cores are 2100
But Show in sysinfo :
Processor (CPU): Pentium(R) Dual-Core CPU T4300 @ 2.10GHz
Speed: 1,200.00 MHz
Once under load they move back up

Get the “My Computer” icon back in openSUSE 12.3 with this: https://forums.opensuse.org/blogs/jdmcdaniel3/s-k-s-i-suse-automated-kde-sysinfo-installer-version-1-0-0-opensuse-12-3-136/
Thank you James!
Have set the CPU freq to “Performance” and the response is much better.
