i7 8700k Did i loose?

[ah.mhanna1987]

literally i did everything to overclock my cpu! i watched a lot of tutorials, followed exactly what on youtube, not sure what going wrong or my chip is that bad!!

cant even be stable on 4.4 Ghz 1.25v !
tried on 5ghz from 1.350v till 1.412v it just cant be stable always freeze on windows or while benchmark.

My specs are:
i7 8700k
Mobo: Asus Maximus x Formula
1 TB SSD
kraken x62 water cooling
850w silverstone gold
G.skill 2x8, 16 GB can reach up to 3000mhz

i heard Ram plays a big role .. should i remove 1 8gb ram and try? would that help?
i see people stable 4.4ghz on 1.1v and me cant even be stable on 1.25v!
and some 5ghz are stable on 1.3v and me i reached 1.412 and still my chip doesnt want to be stable.

should i return the chip to intel?

have you tried letting Asus help you? whats unique about Asus board is the digi+vrm chip tech they have on it. its basically its own OC slash power state stabilizer to allow you to clock higher. you can try resetting your BIOS to its optimized defaults. save & reset. then open the Dual Intelligent Processors 5. you can try manual OC thru that software. starting with its TPU, then the DIGI+VRM. but if you are not yet familiar with it. yo can do the 5-way optimization tool. start from asus optimal ratio. set to TPU 2 since youre using an AIO. and set your preferred values and let it run. 30mins should be enough to calibrate your system. it will give 3 to 4 restarts. once that is all done. you can go to BIOS and check what voltages were set and manually adjust from there. after a couple of retries with the 5way optimization, you can get the hang of what your board can do. then you can uninstall the Ai Suite if you want. and do full manual.

You don't mention your temps anywhere, as i'm you know based on the tutorials etc. it is vital to monitor temps.

i didnt mention i had Asus z370-f and changed to maximus x formula thinking my mobo is the issue but still with the same problem.

Temperature was always high around 80 degress before it freezes .. dont forget im using kraken x62 with very good airflow! i did clear cmos for bios .. formatted my windows and did a clean installation again.

me and my friend have the same exact specs still he is hitting 5ghz on 1.34v and me i cant even hit on 1.412v .. i didnt try to go higher.

ill be trying the Ai Suite on Dual Intelligent Processors 5 and see how it goes, ill get back to you

thats the wrong mindset tho. even if you have the exact same specs. they are not the same. so you shouldnt fret too much about that kinda stuff. and just focus on what stable freqs+volts+temps is limited to what you have rn. if all hardware were built exactly the same, then there wouldve been something on the internet to post OC tweak settings where everybody copies it exactly the same to their own build. but there isnt, is there.

well good luck and always do very little increments. especially on voltages.

80C with good airflow, is still 80c, and that's too hot in my opinion. You may have gotten unlucky.

You may have not done well in the binning lottery.
The key statistic is what multiplier you can run at a reasonably high vcore of 1.4v.
as of 12/01/2017
What % of I7-8700k chips can oc
at a aggressive vcore near 1.4 or so and delidded
4.9 99%
5.0 72%
5.1 43%
5.2 16%
5.3 3%



Note that these stats are for delidded chips sold by silicon lottery.
Intel does not warrant performance past the advertised specs.
That is why they make K suffix processors.

When stress testing, I think 85c. is a reasonable cut off point.
That is what OCCT uses as a default.
Under normal heavy loads, you will not see stress test temperatures.

What is your idle temperature?
If it is more than 10-15c. over ambient, your cooler is not mounted well or has a problem.

Many benchmark programs use AVX instructions which increase the heat generated out of proportion to the instructions typical usage.
There is an option for AVX offset which lowers the multiplier when such instructions are present.

Look to see if ASUS has a motherboard bios update. Often, they include overclocking or ram improvements.

Ram faster than 2400 needs more voltage.
That can interact with your overclocking efforts.
I suggest you run the ram at the best speed 1.2v will allow.
Later, you can try higher numbers using the XMP settings.
Real app performance is not improved much by higher ram speeds as a rule.
I7-8700K is a beast of a chip, so consider anything you can get over stock as a bonus.

When you are all done, implement speedstep.
That will lower the multiplier and Vcore when the processor has little to do.

Should always stress test new build with default settings first. Certainly In the case of 8700k with MCE disabled.

I do this for two reasons, first to eliminate any bad hardware. Second you will be able to see what your particular chips vcore is set at. If for instance you're chip at stock shows vcore of 1.2 then you may have a good overclocking chip, if however you see 1.3 then its very likely you will not get a high OC unless you are willing to pump a lot of core voltage through chip, if at all.

These chips that need high core voltage, will need a delid. No standard cooling solution will get a high over clock without it, period.

For right now this guide is the best we have to work with, http://edgeup.asus.com/2017/kaby-lake-overclocking-guide/

There are some differences and some early bugs that need to be taken into consideration also.

So return bios to defaults, disable MCE check what vcore is set to. If it is high then you may want to roll the dice again, if not then begin your OC from there. Leave XMP off until you stabilize CPU.

When stressing use Prime 95 with AVX disabled, Realbench. Or use an AVX OFFSET, you can dial AVX in later. Real bench will use some AVX, but not at the level at the level prime95 will.

Man you helped a lot and thanks for everyone who replied to me, you guys rock.

i did a stress test on my default settings, i got on 1.32v which is bad as you said for high OC later, but i dont mind as long as mim going to delid it soon.

here is the interesting part, I disabled MCE as you told me and left XMP on Auto i didnt even touch it as default .. i tried 1.35v on 5ghz but windows failed to boot, i reduced to 4.9ghz on same voltage 1.35v and did a stress test on prime95 blind was on 55 degrees and torture on 93 degrees! which i was expecting without being delid yet, even benchmark got a score of 1550 .. everything was stable.

so what i understand is when XMP is on OC is not stable and when Off its stable, then there is a problem with my Rams i guess.
i Have 2x8 gb ram G.skill they are expensive to be honest.
should i remove 1 and try XMP on 1 only see which of them is not stable?

Remember to do one thing at a time and test!

What is cache multipier? May need to lower this, Try 42. If this doesn't stabilize with xmp enabled then, Then try bumping dram voltage some.

XMP dosen't always work right, note the xmp settings from package and input them manually. Take note of vccio and vccsa, write these down for reference.

Test RAM with HCI memtest, divide available ram by cpu threads(12) and input this number into each of twelve instances of HCI. 2000% coverage min.

If you don't have this already, get it. Sensors only. Look for Windows hardware errors heading, I've found this to be invaluable. If your not crashing, no bsod's but there is a value here then you are not really stable. Great for dialing in OC.
