It is cheap, simple RAM. With the low profile sticks you should not have any problems with fitting them under a large heatsink. I did get one stick that was DoA, but Kingston was very helpful in replacing it for free.
This ram came packaged well, plenty of padding and protection; I plugged it in and immediately recognized; I ram Memtest individually and with all 4 sticks (2 kits of 2) for over 12 hours will no errors (over 5 passes)
None
