BusError Posted July 31, 2008 Share Posted July 31, 2008 I've had random crashes the last few days, most especially because I've been ramping up the Hackintosh usage. This machine so far ran Kubuntu, and uses the 8GB with PAE easily for quite a lot of developement work. The 8GB have been tested several times with memtest86 too.. All is thumbs up at up to 3.2Ghz Anyway, seems that Leopard crashes/panics or even plain reboots if more than 4GB is used by the system. At first I tought it was my overclock so I downgraded the machine to stock, but the problem persists. It became really systematic since I installed Lightroom 2.0 that is '64 bits compatible' and thus sucks memory like crazy. Anyone experienced that ? Any fix ? Do I need a 64 bits kernel after all ? Specs: + GA-EP35C-DS3R + Intel Q9300 Quad @ 2.5Ghz (stock) + 4 * 2GB OCZ stick ("8GB Quad Kit", with a +.1V in the bios) + Kallyway 10.5.2->10.5.3->10.5.4 with kernel 9.4 (not vanilla) + nVidia 8600GT 512M + Loads of disk. Otherwise the install recognize everything perfectly and is quite stable; it only crashes when it starts using memory. I removed 4GB and so far I can get it paging and it doesn't crash...

Most probably the Jmicron controller doing it you can try one of two things disable it in the BIOS or use these .kext I found that eliminated that on my machine. kext_for_JMicron_ATA.zip Link to comment https://www.insanelymac.com/forum/topic/118574-1054-8gb-32-bit-kernel-crash/#findComment-840232 Share on other sites More sharing options...
Iam9376 Posted August 9, 2008 Share Posted August 9, 2008 I would really love an update, I have an almost identical setup, except with a Q6600 and periodically, like with unrar'ing a large file will cause a kernel panic. I'm not sure if its because I have 8GB or ram, or if because i installed OS X to an IDE drive or what but it sucks Link to comment https://www.insanelymac.com/forum/topic/118574-1054-8gb-32-bit-kernel-crash/#findComment-849925 Share on other sites More sharing options...
new1phone Posted August 9, 2008 Share Posted August 9, 2008 It surely is JMicron ATA. I have iAtKos4i 10.5.4 .. (enabled SATA/AHCI) before install . everything works, but DVD is on IDE interface and it crashes almost 100% time. I have tried all the JMicron kext's out here .. and the ATA kexets .. (the most recent/latest etc. etc.) and I still have a problem in using the DVD drive. Sad thing is I had it all working wihtout problems.. and I dumbly tried the hatchery tool to clone the drives .. it trashed both -- I rebuilt everything but somehow am not able to get back .. so a combination of kexts are still needed to make it work .. it might be the SMBIOS kexts that I haven't tried .. that's next over this weekend.

Iam9376 Posted August 10, 2008 Share Posted August 10, 2008 After completely removing JMicronATA.kext, setting SATA ports to AHCI and disabling the onboard IDE port increase stability termendously. However it still crashes with memtest w/8GB of ram. Any ideas on how to fix this?

nickhe Posted August 10, 2008 Share Posted August 10, 2008 try installing JAS Client server 10.5.4 it should allow more memory or use 10.6 it's 64 bits and 64 bit in theory should allow 128tb ram Link to comment https://www.insanelymac.com/forum/topic/118574-1054-8gb-32-bit-kernel-crash/#findComment-851563 Share on other sites More sharing options...
Iam9376 Posted August 10, 2008 Share Posted August 10, 2008 Just an update. Found out last night i must have failed to remove JMicronATA.kext, as find / -iname "*jmicron*" revealed it back in /System/Library/Extensions removed with rm -rf, rebooted and attempted memtest again with 8gb of ram PASS. I'm not certain overall how stable the system is, but this is a big leap forward, all previous memtest attempts with 8gb have caused kernel panics. Well, I'm not sure how accurate of a test this is, but here's what i got going right now: (using spaces) VisualHub transcoding a 1.5GB file w/MP4 @ "Go Nuts" settings (h.264) VLC running the same video VisualHub is transcoding XCode (just started, not doing anything) Acitivty monitor + Transmission Did some ~3GB of file copying then unrar'ing Aperature is running Memtest is running so far, no crash, system is a ltitle pegged for resources due to memtest, but otherwise running fine. I'm welcome to other stress test ideas Link to comment https://www.insanelymac.com/forum/topic/118574-1054-8gb-32-bit-kernel-crash/#findComment-851664 Share on other sites More sharing options...

I'm welcome to other stress test ideas http://www.mersenne.org/gimps/ Get the latest version for OS X then change into the directory where you extracted too in Terminal and use /mprime -m to bring up the menu choose the Options/Torture Test (number 15) go through the questions it asks. I would go with the Blend Test as I believe it does the most ram testing once it goes through a couple of hours without error you can use CTRL + C at the same time to kill the test then exit.

pchot Posted August 12, 2008 Share Posted August 12, 2008 just try to use leopard 10.5.5 probably can passed this ??? Link to comment https://www.insanelymac.com/forum/topic/118574-1054-8gb-32-bit-kernel-crash/#findComment-854715 Share on other sites More sharing options...
thedecline Posted December 3, 2008 Share Posted December 3, 2008 I am now experiencing the same issue. I just upgraded to 8GB 1066 Kingston Hyper X ram, now most reports state that ram should be fine. On the p5ke/wifiap (that may be the problem?) you have to overclock the ram to get the full 1066 speed. Upon doing this my system became highly unstable. Now I am running all the default bios settings (memory at 800) with memory remapping turned off, and it's still not stable, it did pass memtest but adobe cs4 pushes it to a kp almost everytime I run it. Was there ever a solution to this problem? I'm running the vanilla 9.4.0 kernel.

I just removed 2 pieces of 2GBs and its back to its rock solid self. Strangely, it worked well with 8GB when I ran AE CS4..

verynice Posted January 30, 2009 Share Posted January 30, 2009 I know its a pain in the butt, I too have 6 GB of ram and it KP's all the time when using memory. I removed Jmicron since I have SATA only and AppleNforceATA. No matter what I do , -legacy , nothing works other than maxmem=3048. Then it's a perfect system other than the dvd burner. What gives, I hope someone can fix it. I also tried the new jmicron and applenforceata and still screw all. We must find some a fix.

Maniac10 Posted January 30, 2009 Share Posted January 30, 2009 As you're using voodoo you can try to boot with the -force64 flag, cause for AMD machines it's deactivated by default.

verynice Posted January 31, 2009 Share Posted January 31, 2009 Nope didn't work. tried installing Vista in Vmware and it crashed, Rebooted with maxmem=3048 and installed it fine.

Yodo Posted February 11, 2009 Share Posted February 11, 2009 Well, same trouble here, but... i update to bios f3, disable ide from bios, and put the memory voltage on automatic, and works ok, tomorrow i make some test with enable ide again GA-EP35C-DS3R + Intel Core2Duo @ 2.2Ghz (stock) + 6 Ghz (3x2@800mhz) + 10.5.4 Retail + update 10.5.6 vanilla kernel + nVidia 8400Gs 256M + 5 SATA disk 1 IDE, DVD IDE.
