Hi, I just bought a 2x4gb kit of the exact same 8gb ram kit I;ve been using for the past 2 years, when I tried to install all 4 ram sticks, my pc wouldnt boot. All sticks work, along with all of the ram slots, but it just won't boot with 4 sticks, however it will boot with 3 sticks, that being 12gb of ram. Pls help!
