Great, cheap, low CAS timing, and reliable, couldn't ask for more from DDR3!
I wish the PCB was black, but it looks good and performs well.
Cheap, and it works. I don't have to say much about it. While playing even the most intense games I don't ever go over 9GB, but my common max is under 7GB. 8GB of a better choice would have done just as well, and would have been cheaper. But I'm not dwelling on it. Although the best range for my needs would have been a 10-12GB setup, it wasn't highly available or cost effective when I was ordering the parts.
Mushkin RAM works. But I'd order even Crucial with no heat sink instead if I absolutely had to cut the budget for whatever reason.
