Hello, it's me again!
Motherboard asus P8H61-M LX
on the ASUS website found about it:
2 x DIMM, Max. 16GB, DDR3 1333/1066 MHz Non-ECC, Un-buffered Memory
I want to take 2 sticks of 8ggb RAM, DDR3, Kingston frequency 1600 MHz model kvr16n11 /
8 1600 MHz memory , or not ... Maybe I didn’t understand the information about the motherboard at all?!

Answer 1

Not critical, simple memory will work at 1333
