I have used two of these 8GB RAM to upgrade my HP laptop from a 4GB of RAM because applications were taking ages to load and applications would crash from time to time and sometimes would not even work. So far, my laptop has held its nerve and not crashed one bit. Applications are now opening much faster than it was before. I now have 16gb in my laptop and everything is ok so far. They are also cross-compatible to other brands even if they are Dell branded.
