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? :-)~MIKE~(-: On Thu, Oct 9, 2014 at 9:41 AM, Carruth, Rusty wrote: > Michael – Wow, I’m glad Mark thought to check the max memory for the > computer!
