Title:
CPU Frequency Scaling Monitor reports incorrect CPU speeds when
overclocked
Status in linux package in Ubuntu:
Expired
Bug description:
The reported frequencies of an overclocked Core 2 Duo are incorrect.
Benchmarking and performance testing can confirm that the CPU is
running at the overclocked speeds, but the values reported through
cpuinfo are the standard stock speeds.
CPU has been overclocked from stock 3.00GHz to 3.60GHz. This can be
confirmed through dmidecode (output attached). The issue is that
cpuinfo (and related utilities) all report the stock CPU speeds
instead. This is only a visual/reporting issue. The CPU is still
throttling correctly, and the speed is correct as per the overclocking
ratio.
i.e. (tested and confirmed in benchmarks & Bogomips)
Reported 2.00Ghz = (3.6/3.0 * 2.0) = 2.40GHz True Clock Speed
Reported 3.00Ghz = (3.6/3.0 * 3.0) = 3.60GHz True Clock Speed
There are a few reports of this in the Ubuntu forums, however no
resolution had been found. I have updated the BIOS on my motherboard
(ASUS P5Q) to the latest available, with no changes. All other BIOS
options are per standard - allowing CPU throttling/etc.
Bug #132403 makes reference to this similar issue, but this is not a
BIOS problem, only a reporting problem.
Compare:
cat /proc/cpuinfo
cpufreq-info
dmidecode --type processor
Only dmidecode is reporting the correct CPU speed as set in the BIOS.
Regards,
Robert.
