Hmmm....that is a good idea actually. That would allow an easy expansion to 48 or 64 GB in the future. You've got me thinking again.
Is there any issue running just two sticks in this machine?? I guess the base 4-core runs 3 sticks so shouldn't be any issues??
How about running 2 of the included 4GB sticks (from the base 12GB 4-core) and then adding 2 16GB sticks for 40GB total. Any issues with mismatched RAM sizes and brands??
Except for it already has 12 or 16 GB, it doesn't make sense to toss that and refill with 2x16GB sticks. Why not just wait until you want more RAM and then upgrade?
