A couple years ago I attempted to upgrade the RAM in an original Xbox from 64MB to 128MB. That attempt wasn't a success. More recently I tried the original Xbox 128MB RAM upgrade again, this time successfully. This post covers the process of upgrading the RAM in the original Xbox. I cover what I did wrong with my first attempt, and how I was able to successfully upgrade the RAM with my second attempt.
What's the point of upgrading the RAM?
The truth about upgrading the RAM in an original Xbox is that it isn't incredibly useful. You don't really see any benefits while playing retail games or anything like that. There are however some benefits of upgrading the RAM.
