I have a new iMac with 384 mb of RAM. I want to upgrade it to as large as 1gb. Does anyone have any recommendations on memory retailers? or what to upgrade to?
1-800-4memory.com has some of the cheapest prices around, and I have not had troubles from them.
For an ABSOLUTE minimum, you can use the current 384MB of RAM. If you will be doing some heavy work with OS X max it out. If not, at least get another 256MB, but I would recommend another 512MB.
