Hi Folks, so I'm coming to the conclusion that I'm going to replace the 8x1GB modules in my 4,1 and it seemed like 3x16GB would be a sweet spot in terms of getting triple channel bandwidth, while leaving room to add more ram later. Two choices I've looked at are OWC with their branded RAM, or RamCity with a Samsung product. OWC Option RamCity Option The OWC states that their product has thermal sensors built in, the Samsung product is stated as being Registered, I'm assuming the OWC one isn't. The machine is mostly doing image processing. Thoughts and opinions would be appreciated - the price is more or less equivalent between the two. Thanks.
