I'm considering buying a new Dell, but I'd like to have 16 gigs of RAM rather than the stock 8 gigs. The Dell upgrade cost is $175 and I know I can do much better. Here is a page from Newegg showing the type of memory I am considering buying. The only info I have on the Dell RAM is that it is dual channel DD3 1600 Mhz, in two 4 gig SIMMS. The machine can handle another 2 SIMMS so I'm looking at buying 2 more 4 gig SIMMS. Sadly, I know very little about RAM. Are there any other criteria that I need to add to my search to ensure compatibility? Also, of the various Newegg options which is going to provide the best combo of performanc, reliability and price?
