Hello!

So me and my friend decided to upgrade his PC ram with additional stick of 2gb DDR2 ram. But we have issue when we run Windows 10 it says: "Your PC ran into a trouble and needs to restart".
Both sticks of ram are 2gb 800mhz each, though brand is diffrent.They are in right banks, I tried to run each invidually and worked fine. When I put both in, the bios will show that there is 4gb RAM, but windows won't boot.

This is driving me nuts, hope somebody has idea what could it be? Hope I won't need to get another same stick
 
Solution
Probably simply not compatible,, can try with one stick, raise DRAM voltage about + 0.06 and then try with the second stick....What models of DRAM, what CPU and mobo?
