roddoart Posted April 21, 2009 Share Posted April 21, 2009 Hello, This is my first post on the forum. I'm using a low cost hackintosh with the following spec : - Abit I-45C motherboard - Pentium E5200 2.5GHz CPU, recently upgraded from 1.8 GHz Celeron M430. - 2x 1GB DRR5300 Kingston RAMs All is working fine, except that I find the computer rather slow. I used Geekbench on my previous CPU (celeron), and I got around 1770. Looking to the submitted score sounds OK for this type of CPU. Now I upgraded to a new dual-core E5200 CPU, and my geekbench score is .... still 1770 :-( Other benches run on the new CPU : Cinebench R10 : around 2450 (dual CPU), when all tests on the web say that this CPU reach above 5000 ! Xbench : I currently get a poor overall 105 score, with only 91 for the CPU ( Of course I made some search on the forum, and I carrefuly read this topic : http://www.insanelymac.com/forum/index.php?showtopic=98581 But I cannot find any working solutions. Here are my different tests : - SMBIOS output do not report any potential issue with FSB. I tried the smbiosresolver kext to force a fsb setting, but no impact on the benches. - I did not find any valid patched SMBIOS for my motherboard, with hardwired fsb settings, that's why I use the (now deprecated) smbiosresolver. - hacked kernel : I'm using voodoo 9.6 (andy version), with kernel boot flags : fsb=200 busratio=125 busratiopath=0 -notscverify with this options, it seems I can correctly set the system fsb, and even overclock the system by passing fsb = 210, 220, 225, etc... BUT, my benches are still SLOW. I certainly miss something, but I do not undertand what. Can anybody help ?? - Here is my current xbench result : Results 132.13 System Info Xbench Version 1.3 System Version 10.5.6 (9G55) Physical RAM 2048 MB Model iMac7,1 Drive Type Maxtor 6Y120L0 Maxtor 6Y120L0 CPU Test 91.67 GCD Loop 164.39 8.67 Mops/sec Floating Point Basic 76.67 1.82 Gflop/sec vecLib FFT 62.93 2.08 Gflop/sec Floating Point Library 116.06 20.21 Mops/sec Thread Test 171.36 Computation 265.85 5.39 Mops/sec, 4 threads Lock Contention 126.43 5.44 Mlocks/sec, 4 threads Memory Test 138.02 System 144.75 Allocate 158.92 583.61 Kalloc/sec Fill 126.21 6136.55 MB/sec Copy 153.60 3172.65 MB/sec Stream 131.90 Copy 125.23 2586.53 MB/sec Scale 124.81 2578.58 MB/sec Add 141.36 3011.30 MB/sec Triad 137.85 2948.93 MB/sec User Interface Test 159.14 Elements 159.14 730.35 refresh/sec -

Thanks for your help, Romain A new test : if I remove the SMBIOSResolver kext, I got the same bench results, but sysctl reports : hw.cpufrequency_max: 4000000000 hw.cpufrequency_min: 4000000000 hw.cpufrequency: 4000000000 hw.busfrequency_max: 1660000000 hw.busfrequency_min: 1660000000 hw.busfrequency: 1660000000 hmm, it seems that SMBIOS tweaks change the way the system see the hardware... Any idea ? Link to comment https://www.insanelymac.com/forum/topic/163070-help-cpu-fsb-settingreporting-in-leopard/ Share on other sites More sharing options...
