The PE2950 Manual states:
For best system performance, all four, or eight FBDs should be identical memory size, speed, and technology
I currently have 4x2GB in slots 1-4, and would like to use 2x8GB n slots 5/6, leaving room for future upgrades.
What exactly am I sacrificing in not maintaining equality in all 8 slots?
EDIT: adding two more chips is not possible (thanks murisonc); would it be advisable to install 4x4GB (0r 8GB) chips, rather than sticking with 2GB across-the-board (as the manual recommends)?
