Asus auto OC questions

So I installed asus AI Suite because it has some cool features. So one of those is the auto-tuning feature as you can see in this screenshot

So I pressed fast because extreme is probably stupid considering my specs if you look at my signature so I was reading through the warning tips thing and it recommends advanced cooling I think a hyper 212 evo should be ok for just the fast option but I was reading through something which got me a little confused as a noob overclocker of cpus. It said it will adjust the frequency and voltage of the cpu which is normal and the DRAM? um the ram why? Is this necessary for overclocking to overclock the DRAM as well? Is this safe for my corsair 16gb 1600mhz low profile ram?

 

Also I know the 8350 becomes pretty power hungry with a OC so do you think this is ok with my current PSU. I might not keep the OC just wanna see what the program can oc it to

Over clocking RAM is just part of the programs optimization, it will only over clock within reasonable safe grounds, it is unlikely your ram will get hot so long as you have decent case cooling.

What are your complete specs?  

I've overclocked my 2700k to 4.5GHz with AI Suite and it didn't OC the RAM.
