if you want 5GHz operation.
Turn off the HT and decreasing the voltage less than 1.38V.
In the case, the following setting may be your reference.

I'd still give the core cache ratio a try
Sometimes those have a noticeable impact

And as seen from the chart
Some had to lower the value to get stable

Because if you don't lower it manually it has the same multiplier as the cores

LLC Setting: No option " i have it on mode 4 "

you can find it in DigitalALL Power

when i test it on Cpu-z stress never crash and temp aboute 74c

when i test it on ROG Realbench it crash after 3 sec

i raise the voltage to 1.424v and it give me 30 sec and crash again

if i use 1.410v and play games never crash on me

so whats the problem ?

What is your stock voltage?

Are you delidded?

Kaby Lake gets much more stable the colder you can make the chip. To the point you might not even need 1.41V to do 5ghz.

Guys I seem to have gotten quite a poor clocker. Im needing 1.4v in bios with LLC mode 2 which brings it to 1.430v at load for 5ghz. Need to do some more testing and tweaking however it is stable.

Ive delidded and used conductonaut under ihs and gelid extreme ontop of ihs but my load temps seem high for triple rad custom loop. Under prime 95 I get 88/82/86/88 but with occt it max temp was 78°C.

I think above 5ghz is not feasible for my chip.

also there is post talk about CPU PLL , i lower that to 1.18 and give me lower temp
maybe cuz my crash ?
http://www.overclock.net/t/1621111/i7-7700k-temps-vs-ram-speed-on-z270-mainboard
CPU PLL can affect the DTS (temperature) signal alignment skewing the temp to a false low(er) value. I wouldn't lower this much at all.

msi afterburner i use it bcuz fan not work at 50 c
its work on 80c
i will try without it today
IDK - I've been running AB (exclusively) with the last 3 versions of realbench - never an ABeta related problem. Sometimes, SLI can cause RB to hang. AB and RB are "mutex aware" and should not clash. Throw HWi or another monitoring software into the mix, and yeah, a polling clash is more likely. But this should not cause a crash, just a bad sensor reading.

Good to know
Don't know what afterburner these days is good for
Still good to know
Btw
When stesstesting you can just uncheck the box for GPU testing

Where is that box? I'm using 2.54 Realbench and didn't find where to uncheck in the Stress Test section.

when the openCL window opens, uncheck the box(es) for gpus.

If left on auto it can ramp up and give you higher temps

That being said

A not de-lidded chip with 1.4v+ at 5ghz is not going to run overly cool

Still
Lowering you're CPU core cache ratio is the thing I would recommend first

It's like the multiplier for the caches in the CPU
Lowering those has negliable effect on performance

But maybe it's holding you back

I would start at 45 for core cache ratio (or uncore depending on the manufacturer of you're board)

Turn off the HT and decreasing the voltage less than 1.38V.

Http://www.overclock.net/t/1621347/kaby-lake-overclocking-guide-with-statistics/680#post_25878530

I disable any software for monitoring that gives me 180sec and crash with "irql not less or equal "

so I back to 49 with 1.360v seems stable but with high temp after 8min goes to 90c

when I play games temp not goes above 60c so do I need those testing if I only play games?

I would not worry about testing just use the PC for playing games so you can have fun with it.
