I was thinking of adding memory to my 8gb iMac. I use up memory pretty fast when I run Parallels. It's a 2.7ghz Intel Core i5 and the memory consists of 2 4gb 1333 mhz ddr3 chips.
So I'm thinking Apple must sell the memory, but I couldn't find it on their website. I did a google and window shopped at macmemory dot com. I can get 2 8gb modules for $179.
So I'm wondering several things: 1) is that a good price; 2) macmemory a good store? 3) can I mix memory module sizes? There are already 2 4gb modules in the system, can I add 2 8gb modules?
The memory they are selling is
Ramjet uses a Non-stacked module for the 4GB and 8GB DDR3-1333 module for the iMac. The cheaper stacked IC variety of 4GB SO-DIMM draws more power, which increases heat and can cause increased errors. Ramjet ONLY uses premium non-stacked chips.
This just a bunch of sales BS or is it important?
I appreciate your advice.
