Well done.
The 2 Nanya sticks you got NT2GC64B8HC0NS-CG are rated 1333Mhz 9-9-9-24 1.5v.
But your RAM is currently set 1066Mhz 7-7-7-20.
So set memory this way:
DRAM frequency 1333
Timing 9-9-9-24
Voltage 1.5
Bios setup defaults will auto set the memory right.
When done, feel free to re-attach the new screenshot of cpuz MEMORY tab, so I can see if the new settings are correct.
