Hello, i am new at overclocking so i would to ask on few things.
Specs:
Ram - CRUCIAL 16GB (kit 4x 4GB) Ballistix Sport 1600MHz CL9
Procesor - Intel Core i5-3570K
Graphic - MSI N770 TF 2GD5/OC
Motherboard - MSI Z77A-G45 GAMING
Cooler - Noctua NH-U12P SE2
source - Enermax Triathlor 550w

I know i have to Disable Intel Turbo boost and Enchanced boost for overclocking and i can change CPU ratio from 16 to 63 (currently i have it on auto). My goal is overclock it to 4.0 or 4.2Ghz but i have few questions.

1. Can i have Voltage things on AUTO ? when overclocking ? or do i need to change it manualy ? I read that if i am not going over 4.5Ghz i can leav it on auto is that true ? http://imgur.com/a/hwRdd - current settings

2.I am pretty sure that i have to but will still ask - Do i need to change Core ratio limit to same value like if i go for 4.0Ghz overclock so i change core ratio limit for all cores to 40? http://imgur.com/a/xsaPO - current settings

3. If i overclock CPU will be my power consumption a lot higher (noticeable), i mean it by when for example i am not gaming (when i only searching on internet, CPU cores are at 1600Mhz and if i gaming they are at 3800Mhz so when i overclock it will be always on 4Ghz and power consuption will be higher in nongaming mode ? )

3. And last question is about RAM i have Ram frequency on auto, is it worth to change it to DDR3-1600Mhz ? and if i do that do i need enable Extreme memory Profile (X.M.P)



+ This is my Stress test with nonclocked CPU http://imgur.com/a/Mhc5U (CPU temp is 55 not 65 )

Thanks for answers and sorry for my English

This guide is a good place to start; http://www.tomshardware.co.uk/forum/272214-29-wolfram-beginner-guide-overclocking.

In essence you want to disable Turbo Boost and manually set the VCORE; something like 1.2V is a good starting point. Then, set the core ratio to 40. Once, or rather if, the computer boots, run an AIDA64 stress test. You'll know if the test fails because the computer will crash. If it does, increase the VCORE. If AIDA64 is fine after five minutes then lower the VCORE and re-run the test. Repeat this process until the test fails and revert to your last stable VCORE. Re-run the test for at least 30 minutes to ensure stability. Whilst all of this is going on, keep an eye on the system temperatures. Unfortunately, Ivy...

1. You can leave the voltages on auto but you'll benefit from lower temperatures and less power consumption by setting the CPU voltage (VCORE) manually. This involves a lot of trial and error, but it's worth it, and you'll gain a better understanding of the link between voltage and heat.

2. You can change the core ratio for all cores or just one core, but don't go half and half. Go all one way or the other to make management of the overclock easier and improve your understanding of it.

3. Overclocking obviously increases energy usage but whether or not you'd notice it is down to a multitude of other factors, such as your energy supplier, how long you use the computer for, how efficient your PSU is, etc. If you disable the power-saving features in the BIOS and set a manual VCORE with your overclock then the CPU will constantly run at whatever clock speed you designate. You can use offset voltage to mitigate this, but in my opinion, you overclock because you want extra performance, and performance and efficiency don't go hand-in-hand.

4. Leaving the RSM speed on auto will be no different than setting it to 1600Mhz manually. Enabling MXP will let you overclock the RAM but the performance gains simply aren't there.

Thanks for answers, i have few more

So http://imgur.com/a/Mhc5U this is with turbo boost 3.8Ghz and voltage is 1.1709V so if i start overclocking can i start right on 4Ghz? and manually set voltage to 1.17 or 1.2V ? And then test stability using AIDA64 ?

And how i know if its stable ? How long do i need to run Stress test ?

Thanks
