I'm looking to add RAM to my newly purchased G5. According to the manual, you have to use RAM that comes in 84-pin modules. I don't know enough about RAM upgrades to know if this is a typo, or if there is indeed such a thing as pc2700 DDR SDRAM in 84-pin modules. Everything I find online comes in 184-pin modules. If someone could explain this to me, I'd really appreciate it. Thanks!
