I have heard ...if you use all the slots on your motherboard for RAM you get
better preformance then someone who is only using 2 slots. (For example,
putting in 4 256's, instead of 2 516's)

Is this true?

Depends on the chipset and memory controllers. In general, recent Intel
chipsets like the 865/875 work best when using pairs of modules. Two pairs
of 256MB PC3200 modules do not allow for greater memory bandwidth than one
pair, only a greater amount of RAM.
AMD chipsets, like the Nforce2 Ultra 400 benefit even less from pairing RAM
modules. The performance gain in dual channel mode is generally less than 2%
compared to a single module. Exception: Nforce2 chipsets with onboard video.
Those do benefit from using pairs of RAM modules.
