MHz rating from cat /proc/cpuinfo too slow?

[makzu]

I've got a really bizarre problem. I just upgraded from an Athlon XP 1800+ to a 3000+ (Barton core). Things 'feel' a little faster, but I for some reason, well:

Code: Select all

bill@greendream ~ $ cat /proc/cpuinfo

bogomips        : 2564.09

As you can see, it only sees about 1300 MHz. This processor should run at about 2200 MHz. When my computer POSTs, it also says 1300 MHz. But it does see the extra L2 cache...

My motherboard is a Shuttle AK35GT2, and the processor is an Atlon XP 3000+, Barton, with a 333 MHz front side bus. The Shuttle website said that 3000+ Bartons are supported for that model, if I remember correctly.

Is there anything I can do to fix this?

Do you need to adjust any jumpers on your board or change the settings in the BIOS?

You probably need to change the FSB (Front Side Bus) speed in your BIOS to what the processor expects. (Probably 166/333 or 200/400 Mhz) You should also set your cpu multiplier to "default."

If you don't really know what you're doing, choosing "Load Optimized Defaults" in the BIOS is usually a good idea.
