I use the memory in a HP Pavilion DM1 with AMD processor and Windows 8.1. Previously installed by manufacturer Page 2 GB of RAM. For instructions on installing I have received over the support of HP. In principle, everything is very simple. I'm not an IT expert and therefore can only say that I feel a significant speed increase. Overall, the investment has really paid off. I wavered between the purchase of an SSD and an extension of RAM. Ultimately I kept the memory for more important as a recommendation of 4 GB is also given by Microsoft. In addition, the replacement is easier and faster due to a non-required data shift. One probably. I'm still a SSD upgrade next year. So far, this seems to me not however required.
