I am having an issue upgrading my ram in my Alienware Aurora R4

I bought 2 Patriot Viper 16GB kits to upgrade to 32GB on my Alienware Aurora R4 and I am getting no video signal no beeps just fans roaring as if it was starting up normal with these installed. But when I take one out and put a corsair 4 GB it boots just fine on 3 Patriot viper 8 GB each and 1 Corsair vengeance 4GB giving me 28 GB of ram.

3 Samsung 24 inch monitors
Intel i7-4820 CPU @ 3.70Ghz
