Question Computer just freezes after installing new ram

[Riptide0428]

So I recently bought 2 new ram sticks for my pc. I originally only had a single 8gb stick in my pc and I wanted to upgrade to 16gb. I went online and bought a set of 2x8gb ram sticks that were compatible with my motherboard and after installing the new ram my pc would boot up perfectly fine and I would open speccy and it would recognize my ram saying I now had 16gb's of ram. After a while my pc would just freeze however and become unresponsive and the only way to fix it would be to turn of my pc and pull out the ram sticks and put them back in. It would continue to just randomly freeze at times and I tried putting my old single stick of ram in and it would go back to working perfectly fine without ever freezing. Please help me as I would really like to have 16gb of ram on my pc.

This is my original pc specs

What are you trying to say? The ram that is currently in my system is DDR4-3400 and it works perfectly fine?

 

[rgd1101]

you bought 2400?

you bought 2400?

I'm a little confused as I am newer to the pc building scene. So why would the 2400 mhz not work with my system?

Amazon does not show that memory (CMK16GX4M2A2400C16)being compatible with that board.

Corsair shows CMK8GX4M1D3000C16 (1-8GB) in the vengeance line as being compatible, I couldn't find pairs.
Just because it is DDR4 doesn't mean it will work.
Corsair's memory finder is pretty wonky, and doesn't work well.

Also you need to make sure your voltage is 1.35Volts not 1.2.
