Re: [opensuse] hardware frequency modules

I have an AMD Phenom(tm) II X4 955 Processor running on an ASUS M4A78T-E
motherboard. My processor fan was pretty loud, so I purchased a separate
processor fan and heat sink, and plugged those in over my processor
instead of the stock version. Well, it didn't work, and the processor
got up to 130 deg F, and the computer shut down (that is my normal
laptop temperature, but my desktop normally runs at about 110 deg).

Also, the non-stock processor fan (Deep Cool is the brand name) only had
a 3 pin plug for the fan, while the stock version had a 4 pin plug.

So, I went back to the stock version, plugged it in, and it seems to run
fine. However, now there is a problem. My cpu temperature is fine, still
running between 105 and 110 deg F. My fan is still loud, but it runs ok.
The problem is, now I can no longer tell what frequency my processor is
running at. Before I ever swapped out the fans, my system load viewer
would say what speed each of the 4 processors were running at. Now, it
says they are always running at 2111.1 MHz.

Also, when I boot up my desktop (box #1 below) as the services are being
listed on the screen, I get this one line:

Loading CPUFreq modules - hardware support not available


So here is where I need help.

Are each of the 4 processors on my CPU really running at 3211MHz all the
time, or is this just a false reading because the CPUFreq modules are
not loaded?

Also, is it possible that I damaged something on the motherboard or the
processor when the temperature ran up to 130 deg for a couple of
minutes, so that now the processor always runs at that speed?

Is is possible that purchasing a new stock fan and plugging it in will
solve the problem?

Changing heatsink/fans has no effect on clock speed.

130F is at the threshold of max temp. The processor was probably not damaged
running at the temp for a short while, especially if the system is running OK

Your cpu's clock is 3200 (unless you have a Blackie and have changed it).
Less than that and differences between cores indicates that AMD Cool'N'Quiet -
power throttingly - is enabled, otherwise all cores will run at the configured
clock. If the kernel cannot load the cpufreq (power throttling) modules it
usually means Cool'N'Quiet is disabled in BIOS or that the processor model
cannot be correctly read. You don't say why the oem heatsink/fan "didn't
work", but you may have done something that caused the board to revert to
different BIOS settings. Make sure that the BIOS is seeing the processor model
correctly and the Cool'N'Quiiet is enabled; the BIOS will also tell you the
actual (max) clock.
