Have 8 GB RAM.  I am thinking about upgrading to 16 GB of RAM.  (1) What is a compatible RAM and (2) How do I determine exact manufacturer details about installed RAM?  I would like to match with just 8 more GB of identical RAM, but all I can determine from system information is that it has 8 GB of RAM.

Here is what the Service Manual says about that:

 

2 customer-accessible/upgradable memory module slots Supports dual-channel memory Supports up to 8 GB of system RAM PC2-6400, 800-MHz, DDR2

 

So you have 2 slots. Max memory is 8 gigs of DDR2-800 SO-DIMM. The biggest modules made of DDR2 were 4 gigs and a pair of them now at retail is about $200 so you have some valuable memory in your laptop and you have the most memory that laptop can use. When that laptop came out, 8 gigs of RAM was a fantastic thing. 

 

Post back with any more questions.

Thank you Huffer. 

 

Yes, it held the most RAM that was available, but I see now that the Motherboard is maxed out at 8 GB.   Since I have students to tutor 1 on 1, I got the biggest HP Laptop availiable and added a lot of bells and whistles for about $3K+.  Except for the fan, it has been great.  I added a 500 GB SSD and reinstalled Windows 7.  Now it is fantastic.

 

Thanks again for your help!
