I currently have 4 gb of RAM installed in this computer. It is one module in one slot. I have a second slot and want another 4 gb DIMM module.  The one I have now is 240-Pin, DDR3 SDRAM. 

 

Crucial.com comes up with a module with these specs:
DDR3 PC3-12800 • CL=11 • Unbuffered • NON-ECC • DDR3-1600 • 1.5V • 512Meg x 64 •

 

I believe this is the same thing.  Am I right?

I really don't want to have to buy two new modules, if I don't have to.

 

I have Windows 7, 64-bit, if that info is important.

 

Silly, I know -- I could buy it from the Crucial site, but I have other stuff to buy on Amazon and would rather do it all at once.

According to the Dell technical guide on the 380, it only supports a maximum of 4GB or RAM. See page 11.

What the??? I was sure when I bought that thing the specs said it came with 4 GB and had a max of 8GB. That's why I didn't check out a manual first. Now I'm quite confused. I kept seeing stuff for upgrading to 8GB, too. Oh well. It's not like the computer isn't running. It's much better than the last one (on which I still need to run memtest - I did make a new memtest disk, though.)

Maybe Dell changed there specs on the motherboard. If you look at the side of the computer you should have a service tag.  You could email Dell customer support and ask them. But, I think 4GB is plenty if you don't plan on running multiple programs at once.

 

Even if you have 4GB, it may be both RAM slots are filled with 2GB each and you would need another 2 4GB in order to get 8GB. When you open the side of the computer, are both slots filled?

No, just one slot is filled. That I know from running Belarc. It also tells me the service tag number, so I can email Dell and find out.  Good idea. I do often have multiple programs open, as I work online a lot and have different things to do. But it's not like the programs are memory hogs. I have open a couple of browsers, Word, email, and Dreamweaver. Sometimes I also have PowerPoint or Excel open as well. But that's usually it. I just thought I should take care of this issue while I was working on everything else. It's not critical since everything is working okay.
