mcsmart Posted March 18, 2008 Share Posted March 18, 2008 I have a Athlon 64 X2 Dual Core Processor and Mac OS X 10.5.2 (with PCEFI v8) installed on my machine (check my signature). In 10.5.1 (without EFI) System Profiler correctly displayed "Total number of cores: 2". Now in 10.5.2 with EFI System Profiler only shows: Hardware Overview: Model Name: Mac Model Identifier: To Be Filled By O.E.M. Processor Name: AMD Athlon 64 X2 Dual Core Processor 4600+ Processor Speed: 2.4 GHz Total Number Of Cores: 1 L2 Cache: 512 KB CPU Features: FPU VME DE PSE TSC MSR PAE MCE CX8 APIC SEP MTRR PGE MCA CMOV PAT PSE36 CLFSH MMX FXSR SSE SSE2 HTT SSE3 CX16 Memory: 2 GB Bus Speed: 200 MHz Boot ROM Version: Hack.88Z.int.0sh.061193*** (American Megatrends Inc.) Serial Number: YM8659M6*** Is this just a cosmetic problem like the "To Be Filled By O.E.M." or could it cause any problems? Will both cores be used? I've installed procfs and it shows 2 CPUs: dk:proc foobar$ cd /proc/system/hardware/cpus/ dk:cpus foobar$ ls 0 1 dk:cpus foobar$ cat 0/data slot 0 (master), running type 7, subtype 4 40030 ticks (user 1111 system 776 idle 38143 nice 0) cpu uptime 0h 6m 40s dk:cpus foobar$ cat 1/data slot 1, running type 7, subtype 4 40264 ticks (user 992 system 748 idle 38524 nice 0) cpu uptime 0h 6m 42s I do not have any kernel flags in com.apple.Boot.plist . Regards, mcsmart PS: If anybody knows how to get rid of the "To Be Filled By O.E.M." it would not be bad either.

mcsmart Posted September 4, 2008 Author Share Posted September 4, 2008 I just updated my Zepyroth 10.5.2 to 10.5.4 and installed the 9.4.0 StageXNU kernel. This kernel fixes the problem, now two CPU cores are being reported by Systemprofiler. BTW: With StageXNU 9.4.0 I also got sleep to work on my machine. - mcsmart Link to comment https://www.insanelymac.com/forum/topic/94278-number-of-cpu-cores-wrong/#findComment-879301 Share on other sites More sharing options...
