Dell Dimension 4700 memory upgrade question-a mix of DDR2-..

Will be using Windows XP Home SP2.
Just purchased a Dimension 4700 from Dell Outlet; I got 512MB of DDR2-400
RAM(2x256).
I bought an upgrade from Crucial: 2x512MB of DDR2-533 (PC2-4200 . CL=4 .
UNBUFFERED . NON-ECC)
From searching these posts,it seems that the 4700 will run DDR2-533 at the
full speed; is this correct?
Am I better off running ONLY 1 PAIR of the new 2x512MB of DDR2-533 for a 1GB
total RAM;
or should I run BOTH PAIRS (2x512MB of DDR2-533 and 2x256 of DDR2-400) for a
total of 1.5GB RAM running at the slower DDR2-400 speed?
Which configuration would give better overall performance?
I do a lot of Photoshop work, and some light video encoding.

Splitting hairs. More is better. Speed is not everything. However, if you
had been thinking about this before you ordered the new, faster RAM you
could have just ordered it at the same clock speed as the RAM already
present in the system. Now you are either going to use that new, expensive
RAM by itself and have a couple of sticks of spare memory, or you are going
to let that speed go to waste by using the older, slower memory in
combination with the new RAM sticks.
