The grey PNP set will work in a AMD Pc but the special optimizations of the PNP is only activated in the Sandy Bridge cpu Pc.
The two blue sets are different in that the heat spreaders are different and the rest is about the same.
A lot of people don't realize that ram doesn't make much difference in everyday use since ram is basicly just a holdeing tank for what the cpu needs and will use at a faster rate then going to the hard drive every time for the data. The ram is faster access then a spinning platter. That's why they came up with the SSD and a SSD is just like ram and almost as fast.
