What benefit is there in running DDR2 as 2 sticks instead of one. I
need to install 1 GB, so I am considering wather I should get 2 of 512
or 1 of 1024.
Thank you!
BWAHAHAHAAAA....1 stick runs in 64 bit mode,2 runs in 128 bit mode.You'll see a 5-10 percent
increase in benchmarks.A small increase in framerates.
The answer depends on the motherboard, and whether the memory controller
is single channel or dual channel. If you have two or more slots on
a board, they could be sitting on one bus, or on two busses. With
two busses, two sticks can run in dual channel mode, with a slight
increase in performance. Some cheaper motherboards with DDR2, are
single channel. And the manufacturer's documentation, can make this
hard to determine (they aren't very honest about these things -
telling the truth makes for bad marketing).
For more info, tell us the motherboard maker and model number.
You can also go to Crucial.com and try and get some info on
your motherboard there, in the memory upgrade search engine.

Except it doesn't.....http://en.wikipedia.org/wiki/Dual-channel_architecture
Dual-channel architecture DDR/DDR2 SDRAM describes a motherboard technology
that effectively doubles data through output from RAM to the memory
controller. Dual channel-enabled memory controllers utilize two 64-bit data
channels, resulting in a total bandwidth of 128-bits, to move data from RAM
to the CPU.

To illustrate the difference between single- and dual-channel
memory, let?s extend the analogy above. Data is filled into a
funnel (memory); the funnel then ?channels? the data through
its pipe to the processor?s input:
Dual-channel memory utilizes two funnels (and thus two pipes) to feed data
to the processor, thereby being able to deliver up to twice the data of the
single funnel. With two funnels or channels, data is transferred 128 bits
at a time.
