Computer freeze

[Videogeek]

Hey. I just installed two new sticks of ram.

My editing is much smoother now. But I now got a issue. My computer freezes under heavy loads. I ran a memory test and computer froze 10seconds into the test. 

never had this problem before I installed the new ram. I'm very sure that the ram is the problem.

 

I thought I bought the same sticks as last time. But  I found out that the new ram i bought has higher voltage. And faster speed. But they are same brand. Just bought 3 years apart. 

 

Old ones are 2x16 sticks with 1.2 and 2666

New ones are 2x16 sticks with 1.35 and 3200

 

I tried to set channels AB to 1.35 voltage but the problem still occurs. 

 

Is there any way I can solve those problem ? Or do I have to buy one more pair of the new ram sticks?
