How come my Mac read my Ram as 24 GB when I installed four 8 GB RAM into my system and booted through safe boot, since my Mac won't boot normally with the new Ram, but will only boot if I add the two 2GB with two 8GB?

Oh and I'm using Kingston RAM too this one: http://www.amazon.com/gp/product/B007TGZ4UY/ref=oh_details_o00_s00_i00?ie=UTF8&p sc=1

Macs are extremely sensitive to their ram...even when memory paging is not used, the memory modules still have to be very close in their timing and latency and other specifications.  That is why John and Michel and Mike and Mende and I all gave you the same advice, advice based on years of experience.  There are a couple memory suppliers who are Mac specialists, know Macs, and test their products to see that they perform correctly in Macs.  The two best are OWC and Crucial, plenty of links given above.
We all have said the same thing with regard to other brands, they are not reliable and are regular sources of problems encountered on here.  It is very unusual to have positive feedback from users buying ram from Amazon or eBay...we see pretty much a 100% failutre rate from users doing that.
Listen to our advice, get the amount of ram supported by your iMac, from a reliable source.  There isn't much else we can tell you as the memory you now have is not working.
