Upgrading the memory to 4x4g chips on iMac 21.5 inch late 2009. Chips inserted but when repowered it just beeps and does nothing else. Suggestion ??
iMac, Mac OS X (10.7.2)
Is the RAM spec as shown below?
| Maximum Memory | 16 GB |
|---|---|
| Memory Slots | 4 - 204-pin PC3-8500 (1066 MHz) DDR3 SO-DIMM |
Where was the RAM purchased?
Correct and reliable Mac RAM can ONLY be purchased from online RAM sources Crucial memory (crucial.com) or OWC (macsales.com).
I concur with MichelPM. Specifically, Corsair, PNY, and Kingston "Value RAM" repeatedly come up here as problematic in modern Macs. Kingston's standard RAM seems OK but is more expensive (better quality) and therefore few price-sensitive resellers stock it.
Specs were correct. Memory was from Crucial. I removed the cards again and reinserted making sure they were seated properly. Seems to be operating fine, just quicker. Thank you for the reply
You're welcome.
