sai.2905, welcome to the forum! When I purchased my desktop in November, it was shipped with 2GB RAM. It ran fine, no BSOD's or any other problems. I upgraded mine because I watch a lot of videos, and I wanted them to load faster, which worked. What you may have read is that 4GB RAM is considered by many to be the "sweet spot", meaning not too much, not too little. For most home users, anything over 4GB is a waste. 2GB will run fine for many applications. I don't know how much you need for hard core gaming, as I don't care for gaming. Hopefully this post and the ones above will be of help to you. Should you have any more questions concerning this or any other issue, always feel free to post.
