Different brand same frequency

[sayedm1]

Hello everyone here's my modest build
2 GB adata ddr3 1600 mhz
4 GB corsair vengeance pro 1600 mhz
Core i3 4150
Asus h81

When I use both RAMs together the corsair one runs at 1333 mhz while the adata one runs at 1600 mhz
I want both to run at same frequency
Please suggest a fix

All the DRAM runs at the same data rate, to check look in CPU-Z in the memory tab, guessing it is all running at 667/1333 though may be at 533/1066. The true frequency it is running at appears as the 'frequency' you take that x 2 to find effective data rate...the individual 1333 and 1600 you are seeing is the spec data rate for the DRAM
