memory question??

with an assus P4G8X motherboard, i dont understand Dual CHanneling, it says:

RAM: DUAL CHANNEL 4x 184-pin DIMM Sockets (PC2100) ECC/non ECC DDR SDRAM Memory, 4GB Max

What does this all mean? that it can only support dual channeling with PC2100? 😕 This proably sounds newb, but does the 2100 reffering to the speed? ne info would help thx.
 
Intel limits what memory speeds it will support based on the speed of the frontside bus of the processor. With a 533MHz bus CPU, 2 channels of PC2100 memory is the fastest you can set, because 266MHz x 2 = 533MHz equivalent bandwidth. If you have a 400MHz bus CPU, you could only run at PC1600 speeds because the bandwidth matches it. If you overclocked the CPU bus, it would overclock the memory bus to match. Officially though, it only supports up to 533MHz FSB and 266MHz PC2100 memory.

PC2100 is 266MHz DDR memory (2100MBps bandwidth). PC1600 is 200MHz DDR.

Dual-channel is supported no matter what the memory speed, as long as the modules are matched in each channel. So if you use two modules, one goes in each channel (don't know the layout of the slots based on what channel they connect to) and they have to be the same exact type of module, and if you use 4 modules then all 4 have to be the exact same.
