Try going into bios, setting the timings and voltage which is writtten on the sticks, they will be the first 4 you find. Set the timings and voltage by hand (manually). Increase your CPU-NB to 1.2. See if that helps. Sometimes running more than 2 sticks, the memory controller needs some help. If that does not work, we are going to be doing a lot of testing to find out the problem. Also, please show a screenshot of CPUz on the memory tab.
EDIT: according to the screenshots in CPUz, the memory is the same make, model and is correct, if they are a matchedset. Modules are made in sets and tested to work together and that is what you want. Sometimes, even the same models, if not a set, do not run well together. When you bought them from Microcenter, were they in 1 package, packaged by Crucial?
