Hello,
Potent Build Parts:
- CPU: Intel i7 6700k
- Cooling: Corsair H100i v2
- Memory: 16GB G.Skill Ripjaws 2133
- Motherboard: MSI XPOWER Titanium Edition
- Power Supply: Corsair HX1000i ATX Modular Platinum
- SSD: PNY 480GB 2.5" SATA 6.0Gb/s
- Video Card: XFX AMD R9 390 8GB DDR5
After assembling the build and maintaining stability for about a week, I’ve chosen to begin overclocking the 6700k. The maximum setting I achieved was 4.8GHz. I kept adaptive CPU ratio enabled because testing with CineBench showed it reaches the 48x multiplier and registers a 1035 on the CPU test.

The only concern is the voltage multiplier. These automatic BIOS options are a bit confusing, so I decided to keep them active, given the excellent overclocking reviews for my motherboard. During a Prime95 blend test, my CPU core stabilized at 70°C with H100i v2 running at full speed (around 2700rpm). The voltage increased to 1.51V. Is this acceptable? Should I allow the automated settings or lock the voltage? Or is it too high for my system overall?

TLDR
: My 6700k hits 1.51V on adaptive CPU voltage during Prime95 blend at 4.8GHz. Is this safe?

yes it's too high,
and it's not just prime95 doing that (and for heaven's sake STOP testing with prime95 on Skylake!), it can/have/will happen in normal use too, (happened to me personally until I tweaked that naughty BIOS), and other users too
Max recommended Vcore is 1.35volt, and i wouldn't risk going above 1.4 nor would I suggest it, better stick with what's "safe"
