I'm building a new server with 7.0 BETA4 (it will track stable) with the following CPU CPU: AMD Athlon(tm) 64 X2 Dual Core Processor 5000+ (2600.02-MHz K8- class CPU) Origin = "AuthenticAMD" Id = 0x60fb1 Stepping = 1 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=0x2001<SSE3,CX16> AMD Features=0xea500800<SYSCALL,NX,MMX+,FFXSR,RDTSCP,LM,3DNow!+, 3DNow!> AMD Features2=0x11f<LAHF,CMP,SVM,ExtAPIC,CR8,Prefetch> Cores per package: 2 What optimizations should I make in make.conf? The example make.conf says AMD64 architecture: opteron, athlon64, nocona, prescott, core2 But I don't know whether althon64 or core2 would be the safest and most appropriate. Also GENERIC for amd64 lists cpu HAMMER is that the best (only) choice? And if not, where can I find a list of alternatives? I didn't find anything in the NOTES files telling me what was available. -j -- Jeffrey Goldberg http://www.goldmark.org/jeff/
