So they can take advantage of people that don't want to shell out hundreds for a new computer, so they upgrade to 'solve' the problem. I have 1 1GB stick, and 1 512MB stick, both DDR266 (PC2100). Once I test them, you can have them for $5 + shipping, if interested.Don't care honestly Its just an old pc I'm wanting to add more ram to, its in my guest room so its not the pc I'm gonna be using. Just don't wanna spend 30+ per 1gb... I don't get why they overprice old memory...
