AthlonX2 - only one processor found - 2.6.11.4-20a-smp
i have an athlon 64 X2 4400+, running suse 9.3 (2.6.11.4-20a-smp). MB is VIA K8T890-9.
it seems to know that it is dual-core, but i can't tell if it's actually treating it as 2 processors. maya renders are not any faster than with the non-smp kernel, and my VR apps (sgi's OpenGL Performer Perfly) report only 1 available cpu. from /proc/cpuinfo, i see that it reports a dual-core correctly, and that there are 2 siblings ... is this the correct output, or should i be seeing a listing for processor 0 and processor 1? --skullmunky cat /proc/cpuinfo processor : 0 vendor_id : AuthenticAMD cpu family : 15 model : 35 model name : AMD Athlon(tm) 64 X2 Dual Core Processor 4400+ stepping : 2 cpu MHz : 1005.040 cache size : 1024 KB physical id : 255 siblings : 2 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 pni syscall nx mmxext fxsr_opt lm 3dnowext 3dnow pni lahf_lm bogomips : 1980.97 TLB size : 1024 4K pages clflush size : 64 cache_alignment : 64 address sizes : 40 bits physical, 48 bits virtual power management: ts fid vid ttp cpu cores : 2 |
What does top say.
I suggest any distribution but SUSE. Try using the latest stable kernel from kernel.org |
in top, last cpu field is always 0; "I" or "1" says "sorry, only one cpu detected."
thanks for the help ... hopefully i can get this working w/o changing distros ;) |
Try the latest stable vanilla kernel version from kernel.org.

(conclusion)
in case anyone else has a similar problem & stumbles on this: that motherboard doesn't support dual-core. oops. |
Get a Sempron and update the BIOS.
