I've been upgrading my mp1,1 recently, and I'm now wondering what would be the best ram configuration. I'm thinking of getting a minimum of 8 GB. I don't need to max out the machine or anything. It's just that I currently have 2x512MB + 2x1GB = 3GB and I am thinking I should ditch those and get nice matching sticks with more capacity. A few general questions: I hear the mp1,1 takes 667 MHz ram, but can support 800 MHz sticks (it will just run them at 667). Any purpose in getting 800 (i.e. compatibility with more machines in case I upgrade in the future), or should I just go for the cheapest? I've heard of triple channel ram (i.e. 3 sticks per riser) - does the mp1,1 support that or is it for newer machines only? I've also heard that using 4 sticks on a single riser is the fastest config (or was it 2 sticks per riser?). Any truth to this? I'm thinking of getting 4 GB sticks. Can I use 8 GB sticks? Worth it? Basically, I'm wondering what the general consensus is on the ultimate memory config for mp1,1. Thanks!
