i5 7600k cache overclock help

[klaudmjj]

I never overclocked the cache on a CPU. Before I do, does anyone have any advice?
Does it make a difference? Does it increase temps and if so how much?
I have overclocked my i5 to 4.7ghz at 1.175v (still testing as 1.15v bluescreened)
I have a be quiet pure rock slim and my idle temps are around 38-43c. (4.5ghz at 1.1v is 35-40c)
Also, I have a Asrock Z170 Extreme 4

The max I've seen it go on a benchmark was 68c and gaming (usually rust) is around 48c
I do care about temps as I have my computer on 8+ hours daily and is used strictly for gaming and some light editing on sony vegas.

In rust which is the game I play most, I get a lot of stutters when the game is loading the map. I have a HDD and I know getting an SSD will fix this, however , after I overclocked my CPU to 4.7ghz the stuttering decreased a lot and I'm wondering if I overclock the Cache if it will decrease it even more. Any advice will be greatly appreciated.

You are doing well with what you have done already.
Try upping the multiplier a notch or two.
The thing to monitor is vcore. 1.4v should be the max and you have some room left.
I suspect you got a very well binned chip.
For a stress test, 85c is about the target.
You are likely to run out of safe vcore before you run into thermal limits.

So Should I up the voltage when I'm increasing the cache clock? Or should I increase both cache and clock speed along with voltage.

You can just leave the cache as is and up the multiplier and volts.

Try to up the multiplier, I have my i5-7600k running at 4.9 with Dark Rock Pro 3.

I suppose if you really knew how all these knobs interacted, you could do better; I don't.
Just leave the voltages on auto and gradually raise the multiplier and see how you do.
When you reach your limit, back off a notch or two.

And... Implement speedstep and adaptive voltage.
That will reduce the multiplier and vcore when the cpu is not busy.

I have a question, if the Speedstep and Adaptive Voltage is turned on, the multiplier is set to 4.9ghz, is there a lag experience when the clocks suddenly turn up or down?

Not that I notice.

Thanks Geo, if that is the case its better to have it enabled.

I based my overclock on this graph here and then turned down the voltage a little bit on each overclock. On 4.5ghzi used a 1.1v core and on 4.7ghz i used a 1.175 and it worked.

That graph shows a very good chip, and I think you have a similar one.
But... not all chips OC as well. You hear about the good ones, but those with dogs are silent.

Ok so here is what I have done.
I tried 5ghz at 1.375v, it worked, however, the max temps were at like 95c.
I turned the voltage down to 1.35 and the temps went down to 91c
I then turned down the clock to 4.9ghz and turned the voltage down to 1.3 and max temps were 85c.
I turned the voltage down to 1.22 and my max temps now are 74c. https://gyazo.com/1a5f37fe82b27352e9b5ab51814428cf
I didn't know how good of a chip I had, now all I need is a better cooler and maybe I could do a 5.4ghz oc?
