For information on Apple products, try www.apple.com. In this case, 
click on Support and then search for what you want, like "Digital Audio 
G4" and pick the resulting page that sounds best, like Specifications. 
You will find such data as:

Three DIMM slots support up to 1.5 GB of PC-133 SDRAM using the 

     * 32 MB, 64 MB, or 128 MB DIMMs (64-bit-wide, 64 Mbit technology)
     * 128 MB or 256 MB DIMMs (64-bit-wide, 128 Mbit technology)
     * 512 MB DIMMs (64-bit-wide, 256 Mbit technology)

Easy, right? The RAM limit for any computer is the amount the CPU can 
address, so your system cannot use more than 1.5 GB no matter how much 
you install. The Apple specs specify a max of 512 MB chips, so don't 
waste money on 1 GB--unless you feel adventurous and your dealer has a 
no-questions-asked money-back guarantee.

As long as you follow Apple's requirements (above) the DIMM brand is 
irrelevant. I always suggest http://www.ramseeker.com/ as a handy site 
to compare a number of memory suppliers, and to check on price trends 
as well. Be sure to scroll down past the paid advertisers to get to the 
full list--looks like today's best price for 512 MB is $72 including
