It currently has two 1 Gb sticks, filling out it's two slots.

 

I know there are limitations about getting it to recognize up to 4 GB of ram but I'm not sure what they are. I'm trying to decide how much ram to buy, to get it up to 3 GB (or maybe 4 GB).

 

I'm thinking it will only see up to 3GB but I thought I would ask.

 

I've seen where people knowingly by a 4gb upgrade knowing it can only use 3gb. Maybe the price difference just wasn't that much more to go for 4gb.

 

Thanks.

 

Also, assuming it can only support 3gb of ram, how closely would the new stick need to match the one I'll be keeping. The issue is one stick is much easier to get to than the other. Can I run a diagnostic check to gather all the info I'd need to know for a good match? (I really don't want to open the case).

With 32bit Windows OS the max it can see is 4GB. Though I believe it reports that it sees only 3.5. I would get two 2GB sticks and max it out to 4GB (even if it reports only seeing the 3.5). 

 

You can check what RAM you need to buy on crucial's website.

Thanks.

 

Found a nice chart at wikipedia under 'Windows 7'

 

No wonder it was so cheap as a refurb. 64 bit really opens up ram possibilities.

 

But, even 3.5 should help vs the 2 GB I have now.

Should give you a decent little performance boost, for sure.

Yes, using 2 x 2GB DIMMs will deliver the best performance, and a lot of basic configurations have about 3.25 GB available for the OS. How much exactly is determined by the hardware, how much of the 4GB address space is needed to have its memory requirements mapped in.

I ordered two 2gb sticks. I also ordered 2 sticks to upgrade my other Dell notebook.

 

I fixed my washer without calling in a repairman so I treated myself with the savings.

 

I haven't shopped for ram in a few years. It seemed pretty reasonable. Newegg seemed to have good prices/shipping.
