Athlon 64 X2 has 2 cores, but no HT, so you have 2 logical processors, not 4. Same goes for Intel's Core 2 Duo.

Ah, that explains it then, the Xeon machines have multicore and HT, I've a dual, dual-core Xeon and with HT on each core SUSE shows 8 CPU's However on this AM2 machine it has ht listed in the flags, thought that was for hyperthreading: (sure that clock speed is wrong too) /proc/cpuinfo. gs05:~ # cat /proc/cpuinfo processor : 0 vendor_id : AuthenticAMD cpu family : 15 model : 107 model name : AMD Athlon(tm) 64 X2 Dual Core Processor 3600+ stepping : 1 cpu MHz : 1000.000 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 fxsr_opt lm 3dnowext 3dnow pni cx16 lahf_lm cmp_legacy svm cr8legacy ts fid vid ttp tm stc [6] bogomips : 2001.20 -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

no, that is correct. It is in pwr saving mode. Check it under a load and notice the different report.

alternativly, you can set the CPUFreq policy to performance mode: "powersave -f". -- Patrick Kirsch - Quality Assurance Department SUSE Linux Products GmbH GF: Markus Rex, HRB 16746 (AG Nuernberg) -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

Sweet system. You could almost run Vista on that, but why would you. If I had the bucks I would run Quake III on it just to impress the locals. -- ___ _ _ _ ____ _ _ _ | | | | [__ | | | |___ |_|_| ___] | \/ | \ /|\ || |\ / |~~\ /~~\ /~~| //~~\ | \ / | \ || | X |__/| || |( `--. |__ | | \| \_/ / \ | \ \__/ \__| \\__/ -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

It's probably for Hyper Transport, which is the communication bus that replaces the FSB. I don't really know the details except that it enables the two cores and/or two processors to communicate directly with each other, which is much faster and more efficient than to have them communicate via the FSB and northbridge.

Actually, I believe that next step will be in multi-core and hyper-threaded systems. Pentium 4 Extreme has this feature, and I hope other CPUs will adopt this feature as well... -- -Alexey Eremenko "Technologov" -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org
