You can't have too much memory...always max it. Always make sure you order the correct memory. Worked right out of the box.

What can I say, other than the product performs exactly as it is supposed to do. I wish everything worked as well.

I upgraded my Asus Eee PC 1005HA from 1GB to 2GB with this SODIMM for use with Windows 7 Ultimate. It works fine.

Apparently, this was the wrong chip set. Check out the Crucial site. They list a different, faster chip set. Mine works but could have been faster.

Popped 2 of these (i.e. 4GB total) into my Dell Latitude D630 over a year ago in place of a single 1GB.

Pros:
- Dramatic improvement in performance, as expected.
- Great price.
- Reliable - still going strong after a year with no known issues.
- Very few BSODs (XP Pro) and I know the ones I did get were caused by Logitech drivers.

Other notes:
- XP only recognized 3.2 of the 4GB, since it only supports a max of 4GB addressing including address space for all the other system components such as display, ports, etc. (that used up the remaining 0.8GB). I could have probably done a 2+1 GB instead, but its not a significant difference in price, so I have no regrets.
- If you're not sure what memory type your laptop supports, try the Crucial memory finder to determine the RAM specs compatible with your laptop model and then shop for those specs (irrespective of the brand you eventually choose). Note that laptop memory is 200-Pin and desktop memory is 184-pin. Also, DDR and DDR2 are not compatible with each other; DDR is much more expensive and that can't be helped.
