Cache ratio/uncore has been proved to be useless to overclock. Keeping it at stock (not auto) will help stabilise a higher overclock. There is absolutely no use to overclock the cache/uncore. Otherwise a good introductory video.

Here it is 2018 and my 4770k is still going strong, and I still haven't needed to overclock it. Just put a 1080ti in for VR and it's still GPU bound (I'm staring at you Fallout 4 VR). But I figure that when it does eventually start lagging behind I can come back to this great video and squeeze some more performance out of it rather than having to invest in a new CPU, motherboard, and memory.

Looks alot like my setup. Benq xl2420t, 4790k, maximus hero vii, trying to find a stable 24/7 oc on my chip. Temps are good with my h100, but im still scratching my head about what clock, what voltage and which things i need to change other then just enabling xmp, and changing multiplier and manual voltagrle. Llc is on auto.

+CMDR Cmdr its very overkill. I settled with 47 multiplier, 101 on the bclk and 1.335 volts. On water, does not go above 73 degrees gaming or 93 on aida 64. Prbly lower if i repasted too . 4747mhz

I have the same mobo and CPU as you, and the bios automatically set 4.4GHz turbo clock by loading optimised defaults. You can try the level up presets and see where you can get to and then make a note of the voltages and manually over ride them, and maybe try tweaking them down as i'm pretty sure the auto voltage is a bit overkill.

I have all these 3 components, same mobo, evga gtx 1080, and I7 4770K and I used the auto turbo set up and the PC crashed afterwards so I had to manual set it up, guess 4.2 was too much for the CPU or there wasn't enough voltage going to the CPU but 4.0 is very stable.

Manual voltage doesn't have any disadvantages. C States and EIST work with manual voltage, CPU is at 0.0**V at idle. Adaptive is the worse thing ever, it will give you spikes to 1.3 or 1.4 just by opening a web browser.

I know this is an old post on overclocking but, hopefully you're still checking your youtube acquirances on this particular post. I am totally new to overclocking and for a while now I've being learning on youtube videos here, I like your input on this matter and this particular video. I have a 4690K cpu, recently replaced the stock fan to a Hyper 212 EVO. I want to overclock this cpu but, not too heavily....I want to go max 4.2 Ghz which in my opinion will be enough speed for the games I'm planning on playing and this and that. My question to you is: Do I really have to play around with the "DRAM" settings? I have two G.Skill Ripjaws X Series 8GB DDR3-2133 currently installed in my system...does that mean that I should set the DRAM at 2133 Mhz right off the top or leave it at "Auto" ? That's what I want to know.

You're going to be reducing the life of your CPU at those temps and voltages so upto you whether it's worth the performance. Could always try 4.3 or something might be able to do it at a much lower voltage.

That's a very high voltage. I really doubt you need that much and it will be causing that instability in hot weather. I'd reset to defaults and run the OC tuner to see what happens. I'd imagine it'll get you there or close at a much lower voltage. I don't have a great CPU for OC and I managed to get it to 4.2 no bother at 1.2V with a bit of fiddling it now does 4.3 at 1.25V. I'd 1000% be reducing that voltage. I'd rather run at stock boost than stick my voltage that high unless you've got some very good cooling.

All ROG boards are designed to run overclocked, just use the level up feature in the AI suite software for normal use then go manual for benchmarks. If your using an i5 4.2ghz is enough to make a difference and the voltage will be kept low although you will need to bump up the memory cache speed yourself in the bios. For an i7 go with the 4.6ghz setting as that chip turbo's to 4.4ghz stock, the software finds the best base clock setting and fan settings too.
