Sup MacHeads? First time Poster. I ordered the new 27" iMac, fully-loaded, except RAM, I'll install 32GB later. I went to Crucial, as an example, to check-out RAM options. Reading the particulars...I saw two different Volt configurations; 1.35v & 1.5v. Which is the preferred RAM to use? The best deal seems to be 2 - 16GB sets (8GB x 4). I haven't ordered RAM in a long time...I'm out of the loop. Ever since the iPad came to market, I seldom use my current iMac or MacAir. I use the iPad for everything. Any other sites, or brands you want to recommend, please do. Your guidance and or opinions are appreciated.
