Mike,
On page 91 of the Dell Dimension C521 that I sent to you, you can use
memory sticks at 533 MHz, 667 MHz, and 800 MHz. Since the original ones are
800 MHz, you did the right thing by changing your order from 533 MHz to 800
MHz.
Bottom line...unless you were doing a lot of RAM intensive computations on
this machine, you won't see a lot of performance improvement for your
investment of $50 in the memory.
