Is it better to have 4x2GB or 2x4GB of RAM?
Given the choice between either 2x2GB or a single 4GB RAM module with all other advertised aspects being equal (same price, same CAS latency, same frequency, etc.) which one is preferred?
It seems to me that buying the single stick gives greater opportunity to upgrade (especially with a motherboard with only 2 slots anyway), however people recommend matching pairs, and I guess picking up a matching stick at a later date is somewhat unlikely.
It also seems to make sense that two sticks would give twice the performance of a single stick. However does this actually happen? The motherboard in question is dual channel (currently running 2x1GB) which I guess makes a difference here?
