i7 7700k overclock
The voltage you're using is within a typical range for your i7 7700k, but the high temperatures under load suggest it might not be ideal for daily use without proper cooling.
The Kaby Lake CPUs are far more overclockable than Skylake and at lower temps.... here's what we are seeing so far:
Average OC = 5.07
Median OC = 5.10
Average Vcore = 1.36
Median Vcore = 1.37
So you are just a teeny bit higher than the mean / average
Be aware, depending on your setup, you may be hitting Vcores of 1.50 or higher. Just because you set it at 1.395, doesn't mean it stays under 1.395. I have my CPU at 1.385 and it can and breaks 1.50 for short mini-bursts whenever AVX is present. When AVX instructions are present the system will spike voltage up as much as +0.13 volts So 1.395 might hit 1.525 if you didn't curb this activity with other BIOS settings.
if you want to test for this, download RoG Real Bench and HWiNFO...
it leans towards the higher range, but with a good cooler it's fine, as you have. the 7700k is a hot chip and you handle it well. i wouldn't suggest going above 1.4v; most people would advise staying under 1.35. it seems acceptable, but why do you require such a high OC after all?

Run the 8 minute benchmark and during the 3rd test, you should see Corev oltage spike when AVX instructions are present. Again, this will only be for short spikes because you are using a "real application" so this represents what your PC might see under actual usage. if you used an AVX equipped version of P95, you could hammer that CPU for long periods and potentially cause long term damage.
BTW, what is cache multiplier ?
I've lowered my OC back to [email protected] which works fine, another issue I face is having a 16gb kit for 4000mhz Trident Z memory. When I apply the XMP profile the computer fails to boot and manual frequency settings work but are unstable except above 3733mhz. I experience very inconsistent performance in Battlefield 1. Are there any steps I can take to help my memory run at its rated speed?
I've also attempted to boost the System agent and IO voltage but encountered no success.
the memory relies on the CPU. certain processors lack full compatibility with the faster RAM due to variations in silicon manufacturing. simply keep the RAM at its maximum stable frequency. For instance, my 920 uses a ddr3 1600 module with XMP settings, but it only achieves 1066 MHz. it stabilizes at 1500 MHz only when I boost the bus speed for OC to 190.
Depending on your motherboard, there is a setting for reducing core multiplier by a specific number value when AVX instructions are being processed.
It might reduce overall clock speed when hit with avx, but it would allow you to run standard instructions at your overclocked value.
I own an MSI z270 xpower titanium board. I was using 5GHz with a -4 setting and having AVX instructions available. So far, I haven't succeeded in overclocking the RAM, which seems to be the main issue. I'm not very familiar with memory overclocking since I've never managed to run the XMP profile from the motherboard before. Do you have any suggestions or steps I could try to increase my stable memory speed? I'm using 16GB of Trident Z 4000MHz RAM (19-18-18-39).
