memory - Supported RAM Frequency of Motherboard and CPU



I have an ASUS P9X79 motherboard which supports "DDR3 2400(O.C.)/2133(O.C.)/1866/1600/1333/1066 MHz."

My Intel 3820 only supports "DDR3-1066/1333/1600."

I purchased "G.SKILL Trident X Series 16GB (2 x 8GB) 240-Pin DDR3 SDRAM DDR3 2400 (PC3 19200) Desktop Memory Model F3-2400C10D-16GTX."

Based on the statement about the Intel 3820 processor, will my computer still operate despite having this G.SKILL RAM with a higher frequency installed? Will it simply step the frequency of the RAM down to 1600?



Thank you all.


Answer



Yes, it will work.



It will work because the higher speed RAM does not have a higher speed. It has a higher maximum speed. The difference in words might be small, but is essential.



I think it is clearer if you think of it in these terms: Can I still use a car with a maximum speed of 100kmph on a 50kmph road?
