• How to Reset NVRAM on your Mac - Apple Support
You could see the system report by use of a utility instead
of About this Mac. In Mavericks OS X 10.9.5 that would be
System Information (from button in About this Mac) choose
System Report in the next view.
If you choose GO in Finder menu bar, and let it open Utilities
then choose System Information (utility) that offers all info on
the hardware and software in the computer.
According to the info in your post (27-inch mid-2010 iMac)
Maximum Memory 32 GB (Core i5 or Core i7 Actual) 16 GB (Apple)
Memory Slots 4 - 204-pin PC3-10600 (1333 MHz) DDR3 SO-DIMM
The max is 32GB of matching quality RAM... per http://mactracker.ca
Sometimes the quality of third-party memory isn't up to par.
Or a 'close number' part may not be correct for the computer.
So that also can be a source of issues. Usually recommended
reseller sources include OWC macsales.com or Crucial.com.
Good luck in any event...!

Jul 25, 2016 1:59 PM in response to Bkavsby pokey b,Typically yes, that is a problem in that the new memory chips are not being recognized. My Mac originally had 4 GB of RAM, late last year I installed 8 GB more and it appears as below. Where did you purchase the RAM chips? Generally the users here recommend either OWC or Crucial brands (I used OWC). Many bargain brands will not work in a Mac as they are finicky about the RAM chips.

Jul 25, 2016 2:06 PM in response to pokey bby Bkavs,I wonder if I installed the cards incorrectly that is exactly what I did- 4 slots, 2 were occupied. I added 2 I bought from CDW, Kingston brand, their recommendation.
is this a cheap brand?

Jul 25, 2016 2:09 PM in response to Bkavsby pokey b,I'm not sure I'd label Kingston as "cheap" but yes, I have seen postings of others here who have also had problems with Kingston and Kensington brands.
