How do you overclock 1600 ddr3 ram to 1800 on my motherboard? Asus M4A79XTD EVO 790X

post #1 of 2
Thread Starter 
I don't see a 1800 overclock setting listed on my motherboard and I thought this motherboard was capable of overclocking ddr3 ram. And would it even be worth it to overclock ram? Or will I barely even notice any speed increase in anything?

Bump the reference clock in tune with a certain RAM multiplier so you can use 1800Mhz.

i.e.
225x8
271x6.66

You may have to adjust other multipliers (i.e. CPU, NB, HT) to compensate.
A similar memory overclock that would be simpler to do and provide a similar performance boost would be to lower the timings. No need to change bus clock or anything. If this is the Ripjaws CL9 kit, you should be able to hit CL7-8-7.

Depending on the apps you use (i.e. video editing?) overclocking RAM may be worth it.
