DDR2 Ram interchangable between laptop and desktop?

The short version, I want to know if my old RAM sticks on my desktop will fit into my friends Laptop, specifically a Acer Aspire 5315.

I looked up the requirements on Crucial.com

I know DDR2 is the main type, but I am unsure about the PC2 -5300 (Non ECC)... i truly do not know what it means.

I upgraded an old desktop to 6GB ram. But didn't realize that it could only support 3.7 with a 32 bit OS. So I essentially have two completly unused RAM sticks.

My desktop is a HP Pavillion a6228x

I know it uses DDR2, but i was unsure if it was interchangeable with her laptop. I was hoping to give her my old RAM sticks, since they are useless on my comp.

I looked it up on crucual as well...

I am not sure if laptop ram and desktop ram is the same... some techy please help. v_V

 

In short, no.

Laptops use SODIMM (small outline dual in-line memory module) RAM, which are about half the size of DIMM RAM modules, which are used in desktops. It simply wouldn't fit in the laptop; it's the wrong size.

You can buy laptop RAM, though, so if she really needs it she can get it.

 

Thanks Misty. And odds are she's going to buy a laptop. v_v

We use it for gaming, and her laptop simply doesn't have the processing power. I was hoping the RAM boost might be a temporary fix.

 

It's better to buy a new laptop than change anything inside this one... laptops are made the way they are, it's rarely seen trying to replace stuff in it.
