    Advice on how go about overclocking my Core i7-3770k

    Hello all :-)

    I have been trying to decide should I upgrade to a Ryzen 5 1600x system or overclock my existing system

    System specs are as follow:

    Core i7-3770k with Corsair H100i water cooling(got this 2 weeks ago)
    Asus Sabretooth Z77 https://www.asus.com/za/Motherboards...pecifications/
    Corsair XMS3 DDR3-1600
    Gigabyte GTX 770 Windforce Edition

    I want to try overclocking but it seems rather daunting and so many videos and guides out there how do I even know which one is going to be the absolute correct one?

    What I am aiming for:
    1) To get 4.2-4.4 GHz out of the CPU
    2) Overclock so the motherboard is able to handle DDR3-2400 ram, here is the link to compatible ram https://dlsvr04.asus.com/pub/ASUS/mb...Memory-QVL.pdf

    I would appreciate advice on how to start this at an incremental stage so I can understand how this all works without frying my system at my first try! haha

    Thanking you

    P.S My Gigabyte GeForce GTX 1080 G1 Gaming should be arriving within the next week to upgrade its graphics capability. And i want to do 1440p gaming!

    There is lots to overclocking, basically leave everything on Auto (volts ;etc) and take CPU multiplier up from say 35x to 37x then 40x , 42,x 45x etc. If Pc doesnt boot, then drop by 200Mhz IE if 47x didnt boot, set 45x, save settings, and try again.

    WHat cooler do you have? HOw many exhaust fans? Where are they placed? Re the RAM, its HIGHLY unlikely you'll get that current kit to 2Ghz , never mind 2400Mhz. Generally speaking, most decent kits will OC to 1 step above their rated speed. IE 2133Mhz should get 2300-2400Mhz, but as with all Oc'ing, your milage will varey.

    I think those bopard have a "CPU Level Up" feature, use that aswell and see how it goes. Once it boots to Win, keep a eye on temps when playing games.

    This is a great, bit of info, it doesn't go veryt indepth into each feature/function, but it explains each feature/function in a basic way. Have fun, learn, and enjoy! Keep in mind you may need to reset your BIOS often , while delving in :P Keep a eye on your temps , as the CPU gets hotter, yopur GPU will get hotter, hence the NB of removing the heat via exhaust fans

    Thank you for replying!

    To get into the cooler and fans on the case here we go..... I will be adding links to everything so you can see it all

    Case : Corsair Graphite Series™ 600T Mid-Tower Case http://www.corsair.com/en-us/special...mid-tower-case
    Front and Side Window Fans : Corsair 200mm (Both pushing air into the case)
    Rear Fan : Corsair AF120 Quiet Edition High Airflow - Pushing in airhttp://www.corsair.com/en-gb/air-ser...-fan-twin-pack
    Cooler Top Case Mounted : Corsair H100i with 2 x AF120 Quiet Edition High Airflow with a push configuration http://www.corsair.com/en-us/hydro-s...uid-cpu-cooler

    I will get started with watching those videos and reading the guide so long,

    I'd say you'd be looking at voltages between 1.25 and 1.35 for a near 5ghz result but I wouldn't keep it at 5, 24/7.

    4.5 ghz easy peasy. 4.7 would help push frames.
    If you're cooler is suffering, try an SP fan and the performance edition, not the quiet. AF fans struggle with radiators.

    Thank you! I will start tinkering tomorrow.

    I have a i7 2600k running at 5ghz 24/7 for a few years now on 1.32V. Every CPU is different, but I prefer manually setting the Vcore as auto mode sometimes over does it. If you're overclocking your ram, you might not be able to achieve as high of a overclock on your CPU. I actually had to downclock my ram from 2133mhz to 1800mhz because I was running into some instability issues at 5ghz. I can't really see a difference in the slower ram speed.

    Re: Advice on how go about overclocking my Core i7-3770k

    Remember to disable VT-d and Speedstep.

    From there you can start with changing the multiplier and the vcore (I would also set it manually). Before you change the vcore take note of what the auto voltage readings say. Start somewhere there (1.25v is a good place to start as well) and push the multiplier until boot becomes unstable.

    Here you have to make a decision. Do you want more OC? Increase the voltage bit by bit until it becomes stable and then continue increasing multiplier. Are you happy with the multiplier and OC but it's unstable? Increase the voltage bit by bit. Happy with the OC and it's stable but it's running hot? Reduce the voltage until right before it becomes unstable.

    It's a balancing act more than anything.

    Unless you're going for an extreme OC of 5GHz+, you should reach 4.5 pretty easily. At that point you can play with the BCLK slightly to get a few more MHz out of it if you must. Don't mess with it too much though cuz things will get out of hand pretty quickly with BCLK.

    If you're happy with the results by only pushing the multiplier and adjusting the BCLK (slightly!), you can then start bringing the voltage down until it becomes unstable and then back to where it was stable. You're basically looking for the lowest voltage required to run stably as this will affect CPU temp.

    In my case I have the 3770 non-K. It has limited overclocking abilities but I was able to get it to 4.2GHz stable and cool with a voltage of 1.19v, at x41 @102.5 BCLK with some help from our friendly forumites.

    However when I booted I found a lot of WHEL errors in Event Viewer but pushing my RAM voltage by a couple notches solved this. Because I left the RAM on auto my 1866 RAM is now running at 1912.

    Here are some basic things I try to remember when overclocking:

    vcore: The juice. You need more of it to support higher clock speeds but more of it creates heat.
    Multiplier: Coarse clock adjustment
    BCLK: fine(r) clock adjustment
