I am building an AMD system and I was looking at purchasing 4GB of Corsair DDR3 1600 memory. I looked the to below and noticed that on the box the one for $178 stated Phenom II and the one for $137 stated Intel I5 & I7 in the pictures see below from Newegg. The only thing that is different between the Two is a letter in the middle of the model # CMD4GX3M2A1600C8 for Intel and CMD4GX3M2B1600C8 for AMD. Is there a difference between these? Would it not be a good idea if I bought the intel ones for my AMD setup? I just dont understand why the AMD sticks are $40 more, when the specs are the exact same.
The modules are different. Most users cannot run 1600 with the A version which is why we make a B version. The A version will run on your system but not likely at 1600. If you want a kit certified for 1600 on your system, you'll need the B version.
