    SoDimm works fine. Had a hard time finding one compatible with my HP laptop as there are 2 different latency times. This one has a latency of 19 while the first one I got had a latency of 17 and didn't work. Tricky things, this techy stuff. Be aware that there is a difference - between it working and not working! Performs great!
