Notebook memory upgrade

[b3mor]

My new notebook (Acer Aspire 5101) could do with a memory upgrade as it is a bit sluggish at times with only 512MB.

It has two memory slots, so am I better off with:

1). A 2GB kit (2 x 1GB) and dump the 512MB

2). One 2GB stick to add to the existing 512MB

3). Just another 512 to take it to 1GB

Although the second option gives me more memory I am restricted to the 533 of the stick in there at the moment and the laptop can take 667 (although I don't know whether this will make much of a difference). Also the first option gives dual channel.

It has integrated graphics, and usage is the usual stuff. Thanks.

Yes the 512MB is a single stick.

I want the best balance between cost and performance, 512MB just doesn't cut it, even in XP.

It is an AMD, single core MK-36 (2GHZ) so nothing special.

If 2GB is beyond what I need for my usage (no encoding or photoshop use, for instance), I could look to add just another 512MB or 1GB stick.

Is the speed of the ram (533/667) of any great importance?
