meisterk Posted September 24, 2007 Share Posted September 24, 2007 are you using any drives on the jmicron controller? Actually I'm using the JMicron controller on my P35-DS3R, connected to an extra HDD and an optical drive (writer). When I get my mobo replacement, I'll do some test with the JMicron kext disabled / or disabled in BIOS.

meisterk Posted September 24, 2007 Share Posted September 24, 2007 I got the problem fix!!I am using asus p5b deluxe and got the problem same as you guys. After plug out all of PCI cards installed (PCI USB,LAN) and disable the Jmicron IDE/SATA controller, the system is fully stable till now. Running Corsair xms 1gb x2, kingstone value 2gb x2 rgb, I didn't see your message, you nailed it ! JMicron is indeed the culprit. Running fully stable with 4Gb of RAM. Thank you very much!

jinrei22 Posted September 27, 2007 Share Posted September 27, 2007 I've set the Gigabyte SATA controller(Jmicron) of my 965p-DQ6 to AHCI mode, removed AppleVIAATA.kext, and, now my Leopard 9a528b installation works fine with 4GB of RAM installed. I have no IDE drives installed, though. At least I got those purple SATA ports working since my ICH8R SATA ports are set to RAID. I could get this recognized as well, but It'll just be recognized as an AHCI drive, not a drive array.

nargot Posted September 29, 2007 Author Share Posted September 29, 2007 looks like disabling JMicron controller in BIOS has fixed all stability issues. cons: no IDE support pros: >3 gb ram support Link to comment https://www.insanelymac.com/forum/topic/55407-problems-with-4gb-ram/page/3/#findComment-459038 Share on other sites More sharing options...
