I'd love to see that. :) sure: ~$ cat /proc/cpuinfo processor : 0 vendor_id : GenuineIntel cpu family : 6 model : 8 model name : Celeron (Coppermine) stepping : 6 cpu MHz : 896.977 cache size : 128 KB fdiv_bug : no hlt_bug : yes f00f_bug : no coma_bug : no fpu : yes fpu_exception : yes cpuid level : 2 wp : yes flags : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 mmx fxsr sse bogomips : 1789.13 > just FYI: > "model name :" should tell you the name and aometimes the design > speed of the cpu > "cpu MHz" the real current speed > "bogomips" issome weird timing value I have no idea what it means exactly It's a semi-arbitrary benchmarking value, usually twice the processor speed. AFAIU.

This is what I guessed, I'm using the values specified in the manual for a Coppermine FC-PGA 600, so: at 3x clock ratio I get: CPU (I assume this is FSB) 100 PCI 33 AGP 66 The display cache runs at 100MHz too, a 1:1 ratio seems logical. One of the reasons I only have 192MB of RAM is because I have already been fussy enough only to use memory that is supposed to run at 100MHz too. No-man's land FSBs are only relevant if overclocking, which is not the object of the exercise for me. I'm trying to optimise. I don't think I'm doing _too_ badly.

I found one here: http://www.motherboards.org/mobot/manuals/All/0/50/ http://english.aopen.com.tw/products/mb/MX3WPro-V.htm I think I might read it now. I'm a bit confused as to why my system thinks it's running a 896MHz CPU, But so far there's no overt signs that it isn't happy, so I'll prod it a bit and see ;-) cheers tim hall
