Seems like the thermal results vary from one review to another so I think we will need to read more reviews to compare. Different review sites used different CPUs and software to stress the coolers.

Mainstream Intel CPUs from Ivy Bridge till the newest Coffee Lake themselves have inefficient stock thermal paste and excessive gap underneath the IHS so these factors also need to be taken into the account. The thermal results won't be as accurate as the ones tested on the enthusiast-class CPUs (ie. 3930K etc) with soldered thermal interface. Furthermore, bigger chips like the 3930K have larger contact surface than the smaller CPUs.

G3D: performs similarly compared to Kraken X62 (based on 4790K)

Vortez: beats Kraken X62 by 13C (based on 3930K)

OC3D: outperforms Kraken X62 by 14.5C (7700K @ 5.0GHz)

Thanks for your kind words... ehh without support from you guys this thread will be dead.
Regarding the low vcore 5GHz OC, I think I am just lucky to have found a nice chip.
No need to resell and buy another chip just to bin for better one like the old days.

https://www.overclock.net/forum/attachment....achmentid=99753 you can get some ideas here

heh it isn't the best board out there but it was the only decent one available when the 8700k launched

i've had several bumps maintaining 5ghz and the biggest one is the fact i didn't delid the cpu

I feel like doing it now tho

Finally I'm able to get my 4x8GB TridentZ RGB (B-die) passed HCl Memtest 300% (~ 4 hours) at DDR4-4400 CL19-19-19-39-2T at 1.50v after relaxing all the tRDWR subtimings to 19 from ASUS's default of 16.

Z390 dah keluar any specialty?

Z390 is just like the Z370 but now comes with native support for up 6x USB 3.1 Gen2 (10Gbps) ports and CNVi (Integrated Wifi-AC) support.

Key features of 9th Core CPUs:

- First performance Intel Core i9 desktop S-series processor Up to 8 cores
- Intel Z390 chipset compatible
- Solder Thermal Interface Material (STIM)
- Integrated USB 3.1 gen 2 and Integrated Intel Wireless-AC
- Up to 16 threads, 5.0 GHz, 16 MB cache, and 40 platform PCIe lanes (16 CPU + 24 PCH)
- Compatible with all Intel 300 series chipsets
- Intel Optane memory and Intel Optane SSD support
- Thunderbolt 3 support

Congratulations! 5GHz at 1.28v, it's a good chip if you managed to stabilize it through stress tests such as RB v2.56.

## to be listed in Post #2, you must post at least a screenshot of CPU-Z consisted of CPU & motherboard/RAM tabs, as well as at least one stable run of Cinebench R15. All in a single screenshot

Nicely done bro. Just remember to set the Power Management in OS to High Performance to kill the CPU speed fluctuations.
Regarding CPU-Z validity, I will include it as an option of requirement. 

Well, ITX doesn't have much space for beefier VRM and the cost must be kept as low as possible hence generally lower quality compared to regular ATX boards.

The only thing I like about ITX is that it has excellent RAM OC thanks to shorter signal path to CPU socket. I'm thinking to get myself the MPG Z390I EDGE AC right now as the Apex will likely not going to be available locally anytime soon.

does using better psu help on the volt stability?

Stock clock and no OC? 

Other than Prime95, you can also stress with LinX, OCCT, Realbench v2.56, AIDA64 etc. All this is listed in the Post #1.

For testing AVX stability, P95 (with AVX/FMA enabled) Custom Blend 1344K min/1344K max for 3hours+ is sufficient enough.
Small FFT will give you unrealistic load, so avoid using it unless your cooling is able to handle the heat output.

Also, watch out for the VRM temp (read via HWiNFO64 if your mobo has VRM temp sensor) as it will get hot very fast without active cooling facing toward the VRM heatsink.

1.23v-1.216 = +0.02v vDrop.
This ITX mobo seems not bad in voltage/LLC control with minimal voltage fluctuation between load and idle.

ASUS Z370 LLC7 max (lowest vDroop is LLC6)
ASUS Z390 LLC8 max (lowest vDroop is LLC8)

Anyone tried the new Cinebench R20 already? 
Here are my results on two PCs...
