I just bought an old iMac DV off ebay to play around with (it would be my first mac ever!). I want to get some more RAM for it, but i'm a bit confused. Checking Apple's website, it says that it takes PC100, with a max of 512mb stick in 2 slots for a total of 1gb of RAM. Now the problem is, which memory should I purchase? Looking around online, the prices for old PC100/133 are much higher, since they are for the most part, no longer in production and no longer price competative. I've found prices ranging from about $45 for a 512mb stick, all the way up to $150. Thats a huge difference! The cheaper sticks are labeled as "generic", and claim to only work with Athlon chipsets, and are not guarenteed to work with Intel chipsets. I can never find a mention for Apple computers, except for places with extremly inflated prices. Does anyone know if these cheap, generic ram sticks would work fine in an iMac?
