grc Posted January 10, 2009 Share Posted January 10, 2009 I'm running an ASUS P5-KPL intel motherboard, E2180 CPU and 8500GT video. The installation is iAtkos 5i vanilla upgraded to 10.5.6 I did have 2GB RAM in here, everything worked perfectly, shutdown, restart and sleep. Now I've upgraded to 4GB by adding a second DIMM, sleep doesn't work. The video shuts down but the graphics card fan still runs (previously, the fan stopped) and it won't wake up again. If I take the RAM out, sleep works again. What gives? Is it the interleaving or something else?

grc Posted February 1, 2009 Author Share Posted February 1, 2009 Can anyone shed light on this? I'd really like to get sleep working with 4GB and I really can't understand why it won't, when 2GB works fine. Incidentally, with the 4GB in, it won't shut down fully either. It gets to the same state as sleep mode, but the thing isn't shut off yet. It needs the power button held in to get it to go off completely.

I've tried with one DIMM in either slot for 2GB - all works. The other DIMM in either slot, all works. With both DIMMs in either way around, no sleep. Still searching for clues as to why it stops sleeping correctly with 4GB on board.

sashabe Posted August 30, 2009 Share Posted August 30, 2009 I have exactly the same problem. Had two DIMMs, both 512Mb. Added one DIMM of 2Gb, now Leopard won't shut down. Sleep has never worked for me, but I don't care. System info is in the signature.

sashabe Posted September 1, 2009 Share Posted September 1, 2009 Tried to reposition DIMMs, no avail, and shutdown doesn't work even with only 2GB module left alone. So I tend to think this is either the module's fault (it's Hynix) or Hackintosh does not play well with a single-channel configuration. Also some random crashes at boot have begun (see here).

sashabe Posted September 7, 2009 Share Posted September 7, 2009 Here's the picture. When it boots after a while, I can see the line after the problem one, it's like ACPI: System State [S0 S3 S4 S5] etc. Tried to use slashack JMicronATA.kext, nothing changed... Changing some BIOS parameters that seem to be related also gives nothing. I work now all day at home, writing the dissertation, and this error comes up only in the morning, after the computer was turned off in the night. Restarting it or powering off and then on after Mac OS successfully booted (during the day) doesn't give the error. That's really odd for me...
