canadrian Posted June 17, 2008 Share Posted June 17, 2008 I was wondering if there are any solutions for the random crashes most users experience when using more than 2gb of RAM. I bought 4gb to allow lots of breathing room on a multi-user machine with lots of applications running, but was getting the usual crashes. So lately I have been using the maxmem=2048, and I thought 2gb may be ok for now... but it seems I'm frequently running out of RAM. Plus it's a pain in the ass to have to make sure I type that on every reboot. I tried editing the default boot flags, but that made my system unbootable. Even if currently 2gb is "enough," it's not going to be the case for much longer. The OS and apps (especially the pro apps I use often) are going to need ever-increasing amounts of RAM. Is there any sort of patch in the works to solve this issue? Does anyone even know what is causing these symptoms, and have some sort of idea how it might be repaired? Many thanks, Canadrian Link to comment https://www.insanelymac.com/forum/topic/111148-any-fix-for-the-2gb-ram-cap/ Share on other sites More sharing options...
JorgeCCastro Posted June 17, 2008 Share Posted June 17, 2008 had the same problem... what's your MB... chipset? Link to comment https://www.insanelymac.com/forum/topic/111148-any-fix-for-the-2gb-ram-cap/#findComment-787668 Share on other sites More sharing options...
Hedyn Posted June 18, 2008 Share Posted June 18, 2008 4GB working just fine here, with a 64-bit kernel (kabylkernel). Mobo is Asus P5B-VM mATX. No bootflags. Note: Switching on PAE made both Windows and OS X unstable, plus Windows didn't see more than 2GB. With PAE off, OS X is stable, and Windows (32-bit) sees 2.75GB.

canadrian Posted June 18, 2008 Author Share Posted June 18, 2008 Here are my specs: Kingston - ValueRAM 2GB PC2-5300 DDR2 SDRAM Intel - Desktop Board DG31PR w/ DualDDR2 800, Video, Audio, Gigabit Lan, PCI-E x16 Intel - Core™2 Duo Processor E4500 2.2GHz w/ 2MB Cache Not sure whether I have PAE and whether it's on. BIOS setting I take it? I am running Kalyway 10.5.1 upgraded to 10.5.2 using an installer I found out about on this site.

JorgeCCastro Posted June 23, 2008 Share Posted June 23, 2008 telling the guy you're running 4Gb with no crashes really helps him solve his problem Link to comment https://www.insanelymac.com/forum/topic/111148-any-fix-for-the-2gb-ram-cap/#findComment-794311 Share on other sites More sharing options...

On Intel website I just got the latest BIOS and applied the update.. It may solve your problem too, but be careful because unsuccessful BIOS upgrades can completely damage your mobo..
