Have to try and see, there are no guarantees when mixing DRAM, at best they might initially play at 1333, but that would depend on mobo/CPU combo, they may only come up at 1066 or less (that's if they even want to play)
Thank u for your reply well i tried and so far everything is good my cpu is intel i5 3350p and my mobo gigabyte GA-H61M-USB3-B3 if i have any problem i will contact u
