memory

[Michael Havens]

yeah? I couldn't find any 2 gig memory chips so I got the two 1 gig chips.
As for the speed of the chips I hope what I got is okay. The chips in now
say 800 Mhz..... oops! the chips I bought are 533 Mhz :( What will the two
different speeds do? Should I buy two more of the 533 Mhz?
