I had existing ram 2x4gb corsair vengeance 2133mhz installed on my asus z97-pro motherboard.
I bought another set of ram exactly the same to fill all 4 slots with 4gb ram each.
Went to load pc, wont boot. Had an error message... blue screen telling me to undo any changes i had made.
I dont know why it is doing this. Why will the pc not work with all 4 slots filled? The motherboard should be able to handle 32 gb ram, ive only got 16 installed! Please help.
 
Solution
Mixing DRAM from different packages is never a good idea, even if same exact model, try raising DRAM voltage + 0.05 and the CPUVTT or may be DDRVTT up about + 0.07
