You have a family 15 one. Maybe it's that, maybe not. BTW, here is my info: CPU: AMD Athlon(tm) II X2 250 Processor (3013.73-MHz K8-class CPU) Origin = "AuthenticAMD" Id = 0x100f62 Stepping = 2 Features=0x178bfbff<FPU,VME,DE,PSE,TSC,MSR,PAE,MCE,CX8,APIC,SEP,MTRR,PGE,MCA,CMOV,PAT,PSE36,CLFLUSH,MMX,FXSR,SSE,SSE2,HTT> Features2=0x802009<SSE3,MON,CX16,POPCNT> AMD Features=0xee500800<SYSCALL,NX,MMX+,FFXSR,Page1GB,RDTSCP,LM,3DNow!+,3DNow!> AMD Features2=0x37ff<LAHF,CMP,SVM,ExtAPIC,CR8,ABM,SSE4A,MAS,Prefetch,OSVW,IBS,SKINIT,WDT> TSC: P-state invariant -- Andriy Gapon
