Memory help needed

My laptop has 2 GB ram total in 2 sticks and im wanting to add more, I have scanned with Crucial and got the memory info I need but am a bit confused over the numerous types of the stick I need.Crucial says I have DDR2-PC2 5300 unbuffered NON-ECC 1.8v 256MEG x 64,,,I am not sure what all that means and so could someone tell me which I need, I have searched and there is lots of DDR2 PC2 5300 but with numerous stats after and I don't know which will fit my laptop

Most RAM will be non-ECC and that's what you want.

It's nearly always mentioned in the specifications at the seller's site, whether that is Newegg, Amazon, or Crucial.

You could buy directly from Crucial if you want. Or get the Crucial part number and locate it at somewhere like Newegg.

Or buy another good brand like Kingston, Corsair, or Gskill.

You should also probably go to the laptop manufacturer's web site and locate your laptop. There should be a specification sheet for that laptop that will tell you the maximum memory it can take and what the specs must be. Pay attention to that.

The Crucial configurator is highly accurate, but not perfect.

The main things to pay attention to are the voltage, ECC or non-ECC, buffered or unbuffered, type (DDR 2, DDR 3, etc), speed (PC2 5300 for instance). You also need to make sure you are getting the right DIMM specification---DDR2 for a laptop is typically 200 pin, as far as I know.

Here's a bunch of DDR2 200 pin DIMMs at Newegg. All of it 1.8 volt, but varying speeds and latencies.

Computer Hardware, Memory, Laptop Memory, New, DDR2 400 (PC2 3200), DDR2 533 (PC2 4200), DDR2 667 (PC2 5200), DDR2 667 (PC2 5300), DDR2 800 (PC2 6400... - Newegg.com

Are you replacing your existing RAM? Or keeping it and adding more? I assume you just have 2 RAM slots? If you have 2 slots and are replacing all existing RAM, you'd need to buy a set of 2 sticks sold as a single unit--either two sticks of 2 GB each (4 GB total) or 2 sticks of 4 GB each (8 GB total), whatever you want.

If you have Windows 32 bit and have no intentions of moving to 64 bit, there's no reason whatsoever to get more than 4 GB of RAM, total. So, you'd get a set of two 2 GB sticks, for a total of 4 GB.

Here's the Newegg list of 4 GB DDR2 laptop kits, non-ECC, 1.8 volt, 200 pin, PC2-5300:

Computer Hardware, Memory, Laptop Memory, New, DDR2 667 (PC2 5300), 1.8V, 200-Pin DDR2 SO-DIMM, 4GB (2 x 2GB) - Newegg.com

I'd probably get one of the lower priced Mushkins or the $45.39 Crucial; no need to spend more.

My laptop RAM is in 2 x 1GB sticks but I want to double that to 2 x 2GB if possible. Does this mean I need to buy a pack of 2 x 2GB.

That depends.

If your laptop has 4 RAM slots total (2 now empty and 2 now used), you could buy 2 more 1 GB sticks and keep your existing sticks; for a total of four 1 gb sticks. All slots would be occupied.

If your laptop has 2 slots total and therefore no empty slots, you must replace the existing two sticks with two new sticks, each of which has 2 GB capacity. Total of 4 GB. Sell the old sticks or throw them away.

I have no idea how many RAM slots your laptop has. It's up to you to find that out.
