System clocked too low

[Roy Sigurd Karlsbakk]

Hi all

I have this server system, a supermicro machine with a PDSMi+ motherboard, 6 gigs of RAM and an Intel Core 2 duo CPU mod 6420, 2.13GHz. The system has been running stably for quite some time, but recently I discovered it seemd a little slow at high traffic times. Digging in, I found it seems to only be clocked to 800MHz, which is a wee bit lower than I would prefer. See below for some debug output.

# cat /proc/cpuinfo
processor	: 0
vendor_id	: GenuineIntel
cpu family	: 6
model		: 15
model name	: Intel(R) Core(TM)2 CPU          6420  @ 2.13GHz
stepping	: 6
cpu MHz		: 800.000

# cat /sys/devices/system/cpu/cpu0/cpufreq/cpuinfo_max_freq 
800000

# cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_available_frequencies 
800000 600000 

# cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_available_governors 
conservative ondemand userspace powersave performance 

# cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor 
ondemand

I've tried different governors without change - I simply cannot set the clock rate to > 800MHz.

Has anyone here seen this happen? Any idea how to fix it?

Vennlige hilsener / Best regards

I all pedagogikk er det essensielt at pensum presenteres intelligibelt. Det er et elementært imperativ for alle pedagoger å unngå eksessiv anvendelse av idiomer med fremmed opprinnelse. I de fleste tilfeller eksisterer adekvate og relevante synonymer på norsk.
