Here's the contents of /proc/cpuinfo on my Dell E521 with the same processor: processor : 0 vendor_id : AuthenticAMD cpu family : 15 model : 75 model name : AMD Athlon(tm) 64 X2 Dual Core Processor 4200+ stepping : 2 cpu MHz : 2205.548 cache size : 512 KB physical id : 0 siblings : 2 core id : 0 cpu cores : 2 fdiv_bug : no hlt_bug : no f00f_bug : no coma_bug : no fpu : yes fpu_exception : yes cpuid level : 1 wp : yes flags : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush mmx fxsr sse sse2 ht syscall nx mmxext lm 3dnowext 3dnow pni bogomips : 4412.52 (second core info snipped) You'll note that mine indicates 2205.548 MHz. -- Jay Leafey - Memphis, TN jay.leafey at mindless.com -------------- next part -------------- A non-text attachment was scrubbed...
