I have great luck using PNY memory in the past as they have never failed. I would definitely recommend.
This is exactly what I needed. Due to clearance issue with my cpu cooler I couldnt use the newer (cool?) styled memory as it wouldnt fit. This did fit perfectly and was recognized up the system at reboot. Adding memory is the easiest way to upgrade your system. But before adding I would suggest you review these 3 questions when considering upgrading;
1) Make sure your motherboard supports the amount of memory you want to add and whether it uses dual channel or not.
2) If using Windows - make sure you have 64 bit system, as 32 but will only use 4GB of memory even if you have more.
3) Make sure what memory your system is using as they are not backward compatible due to the different pins. (DDR2 (old), DDR3 (not as old), DDR4 (current).
I would suggest running speccy (free download) that will give you all your system info such as motherboard, hard drive (and temps), memory specifics, graphics, etc.
