Ok here's the deal... I was looking around for the best deal on RAM (to max out my system), and while on eBay I noticed someone selling 1GB RAM modules for my machine. The specs say that each side can hold a max of 512 for a total of 1G. Being the type of person I am, I wrote this guy and informed him that the system wasn't capable of using the 1GB RAM modules. I thought he hadn't done his homework. He's sold many many items and has 99.7% positive feedback, so he's not a schmuck. Well...
He and I have been writing back and forth, and he actually believes that the C640 can hold up to 2GB of this RAM. He says others have bought it and that he's even running it in one of his own. ...don't know if I believe that last part. Anyway, the only bit of info he gave me as to WHY the machine can run it is because he says it's Low Density RAM. I'm not going to point the guy out, but if you look at RAM for a Dell C640, you'll see people selling the 1GB modules. The wild thing is - He guarantees it'll work.
One of the last things he said is that I'd need to be running a 64 bit OS in order to utilize the whole 2GB. That statement seemed out of the blue, so unless it's important in explaining this, disregard it.
I've checked everywhere I could (Crucial, etc...) and nowhere have I gotten even the slightest hint that this machine can run more than 512 per side (1GB total).
Now can someone either confirm that what I'm thinking is right and that this eBayer is wrong -OR- (better yet) explain how these new 1GB modules can run in my machine. ...and if my machine is even capable of utilizing all of this RAM if I install it. I mean, hey, I'm willing to spend a bit more to give this thing more RAM to work with.
Thanks for any info!
