1.4v is passing beyond Intel's recommended maximums, if you want this chip to last, I strongly recommend you back down. If it needs this, its way out of the comfort zone in every way.
Folks have been overstaing what Intel says for many geneations now... not only for CPUs but for RAM also. Since Sandy bridge folks have been overstating Intel's recommended maximums. And since SB, for RAM those are for non XMP situations. The fact is back w/ Sandy Bridge, there were 100s of RAM kits on Intel's certified compatible lists that were > 1.5v (1.70 even) when everyone was pushing FUD about 1.5v. it was 1.5 v because the JEDEC spec stipulated 1.5v ... but XMP is by definition, not part of the JEDEC spec... same as saying don't go past Intel's boost clocks cause 50 multiplier is above their stated maximums. So when we talk about Intel's stated maximums, we should limit that to what Intel has actually stated publicly.

Legit Reviews contacted Intel about the safe voltage range on DDR4 memory and we received this response.
“1.5v is the absolute max we allow for XMP certifications. However, good DDR4 memory will run at 1.35v up to 3200. Technically, no “safe” (guaranteed) OC over-voltage but 1.35v or lower is best.” – Intel
- 1.2V or lower = Best for DDR4
- 1.35V = okay voltage for overclocking kits
- 1.5V =absolute max voltage allowed for Intel XMP 2.0 profiles and max suggested voltage
As was said in previous post, to my knowledge Intel's max CPU voltage is 1.52. But ya have to identify what voltage you are talking about. This is on a 4 year old 4770k under 24/7 usage
BIOS Vcore = 1.3825
Average Stress test Vcore = 1.391 - 1.423
Peak Instantaneous Vcore = 1.506
In Realbench I try Heavy multitasking 10 times. Is that wrong?
Asus Rog Kaby lake Recommend to use Adaptive mode.
So Can u tell me Adaptive Mode or Manual or is better for this?
If i use 4.9Ghz what do i have to put for this two?
Min. Cache ratio
and Max. Cache ratio
10 Times ?... what's the point ? The RB Stress utility has two functions:
1. Benchmark Button - When you overclock, what are you after ? Best OC for bragging rights ?... best performance ? Sometimes, a higher OC (on CPUs and GPUs) can drop performance. So if ya use the 8 minute benchmark, you get scores which can be used for comparison. For example, I used the graphics benchmark to set my cache ratio.
a. Cache Multiplier = CPU multiplier = reference score
b. Cache Multiplier = CPU multiplier - 1 = reference score
c. Cache Multiplier = CPU multiplier - 2 = reference score
d. Cache Multiplier = CPU multiplier - 3 = reference score
e. Cache Multiplier = CPU multiplier - 4 = less than reference score
So if you use graphics programs, then it's a good idea to drop the cache multiplier to 3 less than CPU multiplier as it has no impact on performance. If you are gaming, there is no impact and you can leave it at default.
2. Stress Testing Button - This **is** what you wanted to do right ? You wanted to stress test the OC so the stress test would be what you want to do. This allows you to see if your OC is stable with ***all*** of your 32 GB of memory. And you don't have to sit at your PC and run the same thing 10 times.... a) this only gives you 80 minutes, b) you should at least get 4 hours in and c) you should want to use all the RAM.
3. Outside of bragging rights, i see no reason why you want to run tour CPU at full throttle when it's sitting there doing nothing. Adaptive Mode recommended to only supply the voltage in accordance with what is needed for the task / load at hand.
4. Cache ratio = default for gaming / typical consumer uses. If using workstation apps, graphics editiing , I'd recommend CPU Ratio -3 (Asus also recommends same) ... so ...
If CPU Ratio / Multiplier = 50 (5.0 Ghz)
Then Cache ration / Multiplier = 50 - 3 or 47 (4.7 Ghz)
