FSB max. = 400x4 = 1600
Here is two choice:
1. DDR2 800 (400mhz) 5-5-5-18 + FSB 1600(400)
fsb:dram = 1:1

2. DDR2 1066(533mhz) 5-5-5-15 + FSB 1600(400)
fsb:dram =/= 1:1

Which is better?
Is it worth upgrading from 1 to 2?
thx

by the way,
single channel really slower than dual channel?
can i hv 1 dual channel 1GBx2 + 1 single channel 2GB?
if yes, it that slower than one dual channel?

thx

DDR2 1066 MHz will be faster, but DDR2 800 MHz modules at 4-4-4-12 and 1.9V are as fast and often more stable. Single channel isn't much slower than dual channel. There's no such thing as single or dual channel memory modules. If you use one module, then it's running in single channel mode. If you install 2 (or 4) identical modules in the correct slots, then it will run in dual channel mode.
