Yes this is major necro, sorry. But others coming here with the problem I was having will want to know this:
Tried everything in this thread and others all over the web, no joy. My particular problem: MacBook Pro mid-2009, had 2 2GB SIMMs installed, was trying to install 2 4GB. Any combination worked, in any slots (e.g., 4GB in slot0, 0 or 2GB in slot1, or vice versa), EXCEPT the intended upgrade: both 4GB installed at same time. Made sure SIMMs were seated properly and not touching anything, reset PRAM/NVRAM/SMC. Nothing, same issue.
Came across this post, last ditch effort: since not an iMac, can't just unplug. Had to unplug and then let run until battery was drained. Let it sit that way overnight. Plugged in and powered up next day - now it recognizes the 8GB! Very strange, must be something besides SMC and NVRAM that gets reset when all power is lost. But thank you for posting, now is working for me!
I just upgraded my 2009 (Model 3,1) and 2010 (Model 4,1) Mac Minis to 8 GB. I purchased the 4 4GB DDR3-1066 RAM cards I needed from RamJet.
I had an enormous amount of trouble upgrading the 2010 Mac Mini's memory because I kept getting the endless beeping anytime I had anything installed in slot 0. I thought initially it was bad chips, but every one of the 4 that I purchased worked fine in slot 1 alone. Eventually what I determined is that it was a hardware problem with slot 0 easily fixed with a small flat-blade screwdriver. What was happening is that the memory card inserted into slot 0 was being unseated slightly when the card was pressed down. The unseating was not enough to see and there was no way to avoid it. What I did to correct it finally was this: after the card was inserted and pressed down, I inserted a small flat blade screwdriver blade between the top of the card and the Mini and then turned the screwdriver blade so that it exerted some additional pressure on the card, pushing it further into the slot. I didn't see any difference or hear any difference, but after doing so the Mac booted up fine and all 8 GB was recognized.
Ironically I had no trouble at all upgrading my older Mac Mini.
