processor : 1 vendor_id : GenuineIntel cpu family : 6 model : 15 model name : Intel(R) Pentium(R) Dual CPU E2160 @ 1.80GHz stepping : 13 microcode : 0xa3 cpu MHz : 1200.000 cache size : 1024 KB The above is part of the /proc/cpuinfo from a Lenovo desktop PC running Debian/Testing. The below is the same from an NEC PC also running Debian/Testing. Both systems are under light desktop load at the moment, and the above Lenovo system still ran at 1.2GHz even when the MySQL bug I previously mentioned was afflicting it. Any ideas on how I can get the Lenovo system running at full speed? According to sensors(1) the Lenovo has a CPU temperature of just over 60C on both cores while the NEC is at 40C and 45C for it's cores. So it appears that there may be some cooling issue on the Lenovo, this would be partly due to the Lenovo being a compact desktop case while the NEC is a medium tower case with a big vent in the side. It would also be partly due to the fact that the Lenovo system is in the home of someone who keeps their thermostat turned up high. But those factors probably don't explain a 20C difference, so I presume that the Lenovo has some dust. In any case as the first temperature threshold is 86C I presume that's not the cause of the clock difference. processor : 1 vendor_id : GenuineIntel cpu family : 6 model : 15 model name : Intel(R) Pentium(R) Dual CPU E2160 @ 1.80GHz stepping : 13 microcode : 0xa1 cpu MHz : 1795.575 cache size : 1024 KB -- My Main Blog http://etbe.coker.com.au/ My Documents Blog http://doc.coker.com.au/
