DIMM vs SO-DIMM

[Slacker]

Looking to upgrade ram in hp g7-1260

HP Pavilion g7-1260us Notebook PC Product Specifications HP Pavilion g7-1260us Notebook PC - HP Customer Care (United States - English)

came with 4gb and specs state 1 DIMM

from what I understand it will only take 1 8gb DDR3 SD >?<

how can I tell the pins or does it matter 204 or 240 will work?

and does SO matter? looking on newegg.com all that came with SO....

**Edit As always thanks in advance for any help

It says it has a maximum capacity of 8GB (2x4GB). There are only two slots which hold 4GB max each.

And DIMM is for desktops, SO-DIMM is for laptops. So you would need to look for a DDR3 4GB SO-DIMM 204-pin.

SO-DIMM is what laptops use. A smaller chip than regular RAM. Hence the smaller size of the laptop.

Each version, DDR, DDR2, DDR3, has different pinouts. Your system will say what version it takes. For you, DDR3.

You need something like this: Newegg.com - CORSAIR 8GB 204-Pin DDR3 SO-DIMM DDR3 1333 Laptop Memory Model CMSO8GX3M1A1333C9

I think it would be better if he gets just one more 4GB stick. So they can dual channel. With one 8GB stick he won't be able to use the other slot or the 4GB stick that came with the laptop.

Thanks to both of you for the help!

where did you find the info on the pins? article I read mentioned 204 or 240

DIMM I was not sure if it was one or two channels and I did read the bit about SO being for smaller machines/notebooks.. but wasnt sure!

what is the difference between one stick and two sticks? wouldn't one full stick be better?

Your laptop takes only DDR3 SO-DIMM which is 204-pins. 240-pin memory is the desktop version, and only for desktops.

DIMM again is only for desktops.

Having two sticks of the same or similar memory will take advantage of having them run in dual channel mode which will increase the memory bandwidth and performance. Running one single stick will run in single channel.
