trexplorer Posted December 4, 2011 Share Posted December 4, 2011 I'm out of ideas. Running 10.7.2 on D630 w Intel GMA graphics. Unresponsive and generally slow (about 1/3 the speed of my mac mini w similar specs). Tried standard boot pack for Lion and also added EDP2.2. Also tried booting w just faksmc.kext. BIOS is A13. XBench scores attached. Suggestions appreciated Link to comment Share on other sites More sharing options...
Administrators Bronxteck Posted December 4, 2011 Administrators Share Posted December 4, 2011 always bump up the bios to last dell revision... i think it's a17 according to our wiki for d630 Link to comment Share on other sites More sharing options...
trexplorer Posted December 5, 2011 Author Share Posted December 5, 2011 always bump up the bios to last dell revision... i think it's a17 according to our wiki for d630 Thanks - but no difference in performance with A17. Can anyone with D630 Intel graphics post their Xbench numbers for comparison. Also tried booting in 64 bit mode (unstable but not any faster).

Tried turning off one core and system is faster more responsive. CPU core speed also reported at 1.99 ghz vs 1.8 ghz w both cores. So likely a problem voodoo TSC sync kext.

Administrators Bronxteck Posted December 5, 2011 Administrators Share Posted December 5, 2011 did you turn off dynamic acceleration in bios? Link to comment Share on other sites More sharing options...
trexplorer Posted December 6, 2011 Author Share Posted December 6, 2011 did you turn off dynamic acceleration in bios? Turning off dynamic accel helps about 5-10%. Just finished installing 10.6.3 with minimum kexts (FakeSMC, NullCPUPowerManagement, TSCsync). Runs about 3x faster (i.e., normal). Removing NullCpuPower causes slow down on 10.6.3 again. On 10.7.2 still can't get any improvement w same kexts (with or without NullCPUPowerManagement). Trying to isolate the problem but it may be a kext in the system that requires removal (tried removing AppleGraphicsControl.kext with no improvement). cheers Link to comment Share on other sites More sharing options...

trexplorer Posted December 7, 2011 Author Share Posted December 7, 2011 Can anyone running 10.7.2 Lion please post their benchmark from Xbench or GeekBench. A list of installed kexts in extra and any kexts removed from System folder would also help. Thanks in advance. Link to comment Share on other sites More sharing options...
