There is a high chance it will work but i can't guarantee it. It would be best if you would save more money and buy two RAMS in one packet of the same memory and manufacturer and use it. I can guarantee that will work.
I have only 2 slots in color blue.. so ?
Then that means the RAMS have to be completely identical. I have a motherboard with 4 slots. Each two slots are of the same colour. I have two different rams. I cannot use both in the same coloured slots but i can use one in one coloured slot and the other one in a different coloured one. Thats why.
