I want to buy more RAM for my laptop. It's a Dell Inspiron 15R Special Edition and I know that it has a slot for an extra 4GB. FYI I'm also running Win 8 64 bit.

I've never installed or bought RAM before, but the current 4GB RAM in my laptop says it is "4GB 2RX8 PC3-12800S-11-11-FP". I looked online and found these two models:

http://www.playtech.co.nz/afawcs0139235/CATID=255/ID=16904/SID=567929501/productdetails.html
I'm just wondering if they are both compatible with my laptop and what the differences are between them i.e. why is one more expensive than the other?

Cheers.

If this is it, (http://www.dell.com/nz/p/inspiron-15r-5521/pd.aspx?ST=dell%20+inspiron%2015r&dgc=ST&cid=33191&lid=783213&acd=1059062008234143) it looks like it uses DDR3L ram, the ram you posted. Well it's 1600 mhz

Which is correct depends on which specific model of 15L you have. Some require DDR3L (the $79 SODIMM you've linked), some require DDR3 (the $69 SODIMM you've linked). Dell list the Special Edition as standard DDR3, but also say it comes with 8GB standard. So, do you have a specific model number?

Ahhh! I found it. The parts list when I bought it says it has 4GB 1 DIMM (4GB x1) DDR3 1600Mhz
BTW the model is Inspiron 15R (7520).
So I should get the $69 one?

Cool, thanks for your help.

Yes, the 7520 will be the 1.5V $69 SODIMM. Dell still show it as coming with 8GB standard (http://www.dell.com/nz/p/inspiron-15r-se-7520/pd), weird - they must have upped it at some stage.

It's probably because I got it last year - I upgraded from Win 7 to Win 8. And I haven't got a touch screen.

Thanks for all your help!
