Dual channel DDR and the E7500 chipset

Greetings! First of all, thanks to everyone for the very helpful
advice offered on this list.
1) Can a single CPU installed alone in a dual Xeon motherboard with
dual channel DDR 200Mhz memory have access to the full 3.2Gb/s
memory bandwidth? I.e. does the chipset restrict each CPU to a
single channel of the DDR memory, or some such?
2) Anyone know of any comparisons/have any experience in the relative
memory bandwidth performance between a single P4 CPU motherboard
with PC800 RAMBUS, and a dual Xeon board with only one CPU
installed and dual channel DDR 200?
3) Certain dual boards appear to support dual channel DDR at 266 Mhz.
Given that the Intel E7500 chipset only supplies a total memory
bandwidth of 3.2 Gb/s, isn't this extra memory speed wasted?
4) Any recommendations of a good dual Xeon board with dual channel DDR
for beowulf applications using a lot of memory bandwidth?
Thanks in advance!
