Question Changed RAM now my PC won't boot up??

[BrandonDaviesFX]

Hello Guys, so I've been running 8GB (2x4gb 2400mhz DDR3) ram for a few years now and decided I wanted to buy 16gb. So I bought sealed 16GB (4x4gb 1600mhz DDR3 and installed in into my pc. When I try and boot it it gets stuck in a loop of boot and shutdown but it doesn't even turn the monitor on. I then try my old 8gb 2400mhz ram and that works, so I just think it might be as I've got 4 sticks now instead of 2 so I try 2 of the new 1600mhz sticks and that still does not boot up. Im wondering if its because its 1600mhz but I don't see how that would affect it. Ive reset the CMOS but I have no clue what to do now.

With the old RAM installed. Make sure XMP is disabled in the BIOS before installing the new RAM.

What is your motherboard? Are you sure the new ram is on the QVL list? Just because it is DDR3 doesn't mean it is compatible. Did you have manual memory settings for your 2400mhz memory in the bios? If so it may be trying to run the 1600 at 2400.
