Inspect the contacts (mine had a dirty spot) 01/01/2014
This review is from: Crucial 1GB 200-Pin DDR SO-DIMM DDR 400 (PC 3200) Laptop Memory Model CT12864X40B
Worked like I hoped & expected. Not a bad deal, considering the performance benefit.
Dirty contacts. In dozens of memory upgrades, I've never seen this before. I don't know if it would have caused memory errors, but I didn't want to risk it. Deducting one star for that.
I bought two of these. When removing from the package, I noticed a dirty spot on the contacts on the back side of one DIMM. I was able to wipe off the dirt with a few passes of a cloth dipped in 91% isopropyl alcohol.
After that, I ran memtest86 overnight. All tests passed.
BTW, the max rated speed in my laptop is DDR333. However, the benefit of using DDR400 is that my laptop run it at CAS 2.5 instead of the rated CAS 3.
I'm running Ubuntu 13.10 on a 90 nm Pentium M (Dothan). Won't run on the earlier generation, due to lack of PAE.
I also installed a Transcend PATA/EIDE SSD. Lots of RAM is key if you're running Linux on a laptop with a SSD. To minimize writes, I have /tmp/, /var/tmp/, /var/log/, and /var/spool/ mounted on tmpfs (essentially a variable-sized RAMDISK). This puts even greater demands on memory capacity. With only 1 GB, I was swapping before I'd hardly run anything.
