CPU and Ram overclocking question

hi guys thanks for reading :) 

i was just wondering if i wanted to oc my 3570k to 4.2 ghz shud i oc the ram also from 1600 its original clock speed to 1866 to help the cpu?

OCing your RAM won't help the CPU and you may just make your system unstable from the RAM. The performance gain from OCing RAM isn't really worth the effort either.

I agree with Scraps. From my experience, RAM is not the thing that tends to quench performance. Instead, it's the IOH transfer rate.

When it comes to RAM, I think it's best to stick to whatever the RAM is rated for (so if it's a 1600 MHz RAM then keep it there)
