I got q6600 2.4ghz + 4ddr3 dual memory +hyper101 cooler +500psu + ga g41-combo mobo
If oc to 3ghz do i need to change my ram setting in bios . coz when the cpu 2.4ghz it shows 1066mhz whereas at 3ghz it show 1333mhz
The difference in the memory speed is due to an increase in your Front Side Bus (FSB), ideally your FSB RAM would be 1:1, or as close to that as possible. Some motherboards allow you to limit the RAM speed and help you achieve that 1:1 ratio. As long as your system is stable and your memory doesn't over heat there is no problem with the higher memory speed but perhaps you could maintain tigher CAS timings at a lower frequency.
