I spent $250 on my RAM. 4 8GB 1866MHz DDR3 dual channel DIMM modules. You could do 32GB worth of 1333's for about the same: Link

Or, you can just get 16GB worth of fast RAM for $164 (Link)

Keep in mind, size doesn't mean a whole lot when it comes to RAM. Pay attention to number of channels (the more the better), CAS timing (the lower the better), RAS timing (lower the better), bank cycle timing (awesome if it is less than CAS*3, and speed (1333 is basically the standard for DDR3, but most motherboards support up to 1866. Good boards will support up to 2400).

Superb references and advice. You've gone out of your way to provide In depth assistance, thank you kindly.

My Predators run DDR4 2400MHz. No doubt I need to opt for that speed. The MOBO can accommodate 64GB, so It won't be too long before I throw In a couple more sticks. There's 4 slots with 2 In use (2x16GB) leaving 2 slots unused. I'm quite happy with the memory's accessibility- undo 2 screws underneath the lappy, the plate comes off and In goes the ram. It'll take 5 minutes at the max, and that's with a blunt screwdriver.
