Will this RAM work and is it worth it?

Hello, I'm wanting to upgrade my laptops RAM and I wasn't sure if this would work in my laptop or if it is a good deal.

Thats the RAM I'm thinking about buying. I'm using a Dell Inspiron 1501 and I'm wanting to know if I that would work I'm my laptop and also if that brand is decent to buy from.
Thanks for any help

You're laptop should support it, but I'm not sure you'll get any improvement, at least not in speed. You're laptop supports 4200 ram which runs at a slower speed, and while it may use the faster ram, it will only be able to run it at the 4200 speed. If you're upgrading from 512 megs to 1 gig, you'll notice a difference. I'd recommend sticking with a 4200 ram. Also, look inside of the manual for your laptop for limitations on the amount of ram. Doesn't do any good if you buy a 2 gig stick and find out it only accepts 1 gig sticks.

I had that laptop and I had 2 pieces of 1GB DDR2 PC2-5300 in there also (for 2GB total). It works fine, but they will run at the slower PC2-4200 speed. You also will want to tell us how much memory you have in your laptop currently. Dell uses 2 pieces of memory in their laptop; so lets say you have 512MB in there right now, it's very likely you have 2 pieces of 256MB. That means replacing one piece of 256MB with the 1GB will give you 1.25GB of memory.
