hey all

i have now:

8gb hyper x ddr3 1600 kingston 2x4gb

and i have a pair of 2x2gb of kingston hyper x genesis 1333 ddr3 left somewhere

i know in bios i have to lower the speed of the 1600 speed to 1333 to be compatible or i will have BOSD


does this will cause some problems in my rig?

lowering the speed of the rams to the slowest stick

they are the same brand but different speed and model

thank you

my rig is:

i7 2600
asus maximus formula 5

1060 3gb
