Well i needed more ram so i bought a single 8gb 1600mhz dimm to replace my 2 4gb 1333 dimms. With my old dimms i could get to a 180 bckl and be stable. But with this new dimm i cant even get it to boot unless i put everything on default then it boots and works fine. I really would like for it to get to a 160 bckl that way my ram will be at 1600 and my cpu at 3.2ghz. But i cant get it to work even though i have seen threads were people have done this with the same cpu and mobo wich is a dp55wb btw. I cant even run the ram at lower speeds i dont know what to do.
