Read/Write on larger RAM-faster? slower?

Memory | Overclockers Forums - www.overclockers.com
Hey guys,

Quick theoretical question - Does RAM performance get better or worse if you have an equal amount of memory but with smaller sticks? Quad channel aside, does 4x4 perform better or worse than 2x8?

The smaller questions that lead to this question are:

1. Say you have an application that requires 2GB of RAM. You have either 1x4 or 1x8 - Both more than enough for the application. Will the application run quicker on the 1x4, the 1x8, or doesn't matter?

2. Now let's say you have 2x4 or 2x8 and an application that requires 6GB. Both are enough but obviously the 2x4 is now almost completely filled (while the 2x8 is not). Does the application now run slower? Does RAM become clogged when the individual sticks are filled?

Would love some insight! Thanks!
