PC133 largely just specifies a speed; there are other factors too. >> 2) What is the difference between Non-ECC & ECC? ECC=Error Correcting Code. This type of RAM has one extra bit for every byte to perform a data integrity check on the data stored in RAM. On many DIMMs (especially desktop ones), you can see an extra hole where an additional chip or two would be added to increase the capacity of the DIMM by 1/8 to hold the ECC bits.

You might get good RAM, you might not; I'd say don't risk it, and go for either Kingston as somebody else recommended, or my personal favorite, Crucial. >> 4) What difference does it make if I buy 2 x 512MB or one 1GB?

Most likely, yes. The vendor should know for sure, but if you get the wrong kind, the RAM can press upward on your keyboard. >> Good Lord, it shouldn't be this confounding?! Well, there are fewer types of RAM than there are models of computers... But everybody wants something slightly different when they're designing a computer, plus every year new technologies emerge...

Often they would charge more because you would get low-profile DIMMs instead of high-profile ones. Kynan Shook kshook at mac.com http://homepage.mac.com/kshook/index.html
