Hello, I am using the Kingston HyperX DDR3 1600Mhz 2G on my motherboard Asus p8b75-v and in default bios settings it runs on 1333MHz so I need update its setting to 1600MHz, in the bios setting do I need to adjust the timings?!! or should I leave it on auto, I will increase the voltage to 1.65V with no trouble because its already the max volt that the ram can manage.

Leave it at 1333MHz and 1.5 volt. 1.65volts can damage the memory controller on the CPU which has a limit of 1.575.

I am using Kingston HyperX Blu 2GB DDR3 1600MHz on an Intel Core i3-3220 which support the memory bus.

Yes but the CPU does not support the 1.65volts. http://communities.intel.com/thread/30798


Ok, so now I have may ram on 1600MHz and the voltage is 1.65v, if I downgrade them to default 1333MHz with 1.5v then I will not have the full performance from my Ram :(  but I can select the 1600MHz without increasing the voltage, to be set on 1.5v will this damage my ram?!

Best solution

If they run at 1600MHz with 1.5volts you are fine but the performance difference between 1333 and 1600 is nothing noticeable, especially with the faster timings of the 1333 speed.

I already did that and it was fine running my ram at 1600MHz with 1.5volts when I the made bios config the first time, thank you for the great tip.
