Installing RAM in pairs can save time and money.
Installing RAM in matched pairs speeds up the performance of certain applications. When it's a requirement, as in computers with the Mac G5 chip(s), the computer will not function properly without matched pairs of RAM chips.

DDR2 RAM is slightly smaller and has square chips. DDR1 RAM has rectangular chips.

short answer : cache chip is more expensive than ram
RAM memory chips should be installed in single chips or matched pairs. You can not put in a 1GB together with a 2GB chip. You can not put in the wrong chip speed, ie a 667MHz chip. The newest iMac can support one or two 1GB or 2GB 800MHz DDR2 SDRAM SO-DIMMs. The lowest RAM is 1GB. It will also accept 2gigs via 1 2GB chip or 2 1GB chips. The max RAM is 4GB via two 2GB chips. RAM is installed in 1, 1+1, 2, or 2+2, sets.
This depends on the computer chips in question. If they are surface mounted chips, no. But if they are socketed or soldered through the board, they can be replaced.The CPU and the RAM are "computer chips," and replacing them is fairly simple. However, you would not be able to replace the chipset chips, and even if you could get them off without damaging the motherboard, finding replacements might be a bit difficult, and installing the new ones would be impossible for the average home hobbyist.
