DrXenon Posted May 28, 2006 Share Posted May 28, 2006 My Asus A8N-SLI board has a single 1GB stick installed in it. System Profiler reports 8GB. If the OS thinks there's more RAM than there actually is, it could lead to major problems. Anybody else seeing this? (I'm using the JaS 10.4.6 DVD.)

simisimisimi Posted May 28, 2006 Share Posted May 28, 2006 what kind of problems could it lead to then? Link to comment https://www.insanelymac.com/forum/topic/18523-memory-size-reported-wrong-in-system-profiler/#findComment-121043 Share on other sites More sharing options...
Colonel Posted May 28, 2006 Share Posted May 28, 2006 I don't think there are any problems that this could lead to. Link to comment https://www.insanelymac.com/forum/topic/18523-memory-size-reported-wrong-in-system-profiler/#findComment-121047 Share on other sites More sharing options...
DrXenon Posted May 28, 2006 Author Share Posted May 28, 2006 If the OS thinks there's memory at, say, 2 GB, it may try to write there. When it does, there won't be any chips there, and at best the kernel will panic. At worst, the system will simply hang forever waiting for an ACK line to be asserted. Trust me, this is a major issue.

Jeezoflip Posted May 29, 2006 Share Posted May 29, 2006 Thats awesome and sux at the same time. At least you can show all your friends your "About this Mac" dialog and blow them away.

DrXenon Posted August 13, 2006 Author Share Posted August 13, 2006 I have since discovered that this seems to be a bug in System Profiler and that the OS actually has a correct view of how much memory I have. Running "top" in a terminal window yields: Processes: 56 total, 2 running, 54 sleeping... 179 threads 19:06:58 Load Avg: 0.13, 0.11, 0.07 CPU usage: 6.6% user, 5.7% sys, 87.7% idle SharedLibs: num = 136, resident = 33.2M code, 4.46M data, 7.38M LinkEdit MemRegions: num = 6628, resident = 178M + 19.4M private, 117M shared PhysMem: 91.6M wired, 159M active, 294M inactive, 545M used, 478M free VM: 9.21G + 88.1M 27955(2) pageins, 0(0) pageouts Note that the PhysMem stats seem to be correct for a 1 GB memory stick. iStat Pro gives similar numbers, so I'm fairly confident that everything's okay.
