I am brand new to the forum and to overclocking and I am hoping some experienced forum members might be able to spare a few minutes to help me out with my first baby steps into the world of overclocking. Many thanks in advance and also apologies for the level of detail set out below. A few things have got me stumped at the moment and. as I am not entirely sure what might be relevant, I thought it best to err on the side of too much detail rather than too little.
Maximus VIII Hero Bios version 3504
16 GB Corsair Vengeance LPX DDR4 3000 MHz (2 x 8GB)
GPU - GTX 1070 Strix Gaming OC 8GB
Noctua NH-U12S CPU Cooler
EVGA Supernova 750W G2 PSU
Samsung 850 Evo 500GB for OS, utility programs and games
Western Digital Blue 2TB for storage
Fractal Design R5 case with 3 X 140mm case fans (2 intake at front and 1 exhaust at rear)
Windows 10 Home 64 bit
Up to date Windows drivers and current Bios for the motherboard. Running reasonably cool, pretty much silent and stable at default settings.
What I am trying to do and where I am at currently:
I am looking to set up a relatively conservative "everyday" overclock at around the 4.4GHz mark for gaming - BL2, Fallout 4, Dying Light and the like at 2k resolution. I have been familiarising myself with the Bios, reading/watching a number of "how to" guides on the internet and have been through Chino and der8auer's guides on the forum here several times.
Where I am at currently is a CPU core ratio of 44 with the base clock left at 100 and a manual voltage setting of 1.265 volts with a load line calibration setting of 5 (8 being the maximum). According to CPU-Z/HW I am getting the 4.4Ghz on all four cores and the memory is running at the advertised frequency. (I have set out the Bios settings I am using detail at the end of the post.) This set up is passing Realbench and aida64 stress tests, giving me a good performance bump over stock on Cinebench R15 runs and appears to be completely stable during normal use. I know the Noctua NH-U12S is not exactly "heavy duty" but CPU temperatures seem pretty good - at around 22 degrees ambient, stress tests are topping out at 70 degrees, the system idles a bit over 30 degrees with maximums in everyday use topping out in the mid 60s with mid 50s being a typical average for "heavy" gaming. GPU max temps during heavy gaming are mid 60s.
So far so good (I think) but I did have a few questions and (potential) issues:
1. With the CPU core voltage manually set at 1.265 volts, HW is from time to time showing maximum volts at 1.280. Is this a function of the line load calibration or is something else going on here?
2. Similarly, I have manually set both the CPU VCCIO voltage and the CPU system agent voltage at 1.1 volts but when looking at these values in the Bios they are both showing up to 1.136 volts. What is going on there? If I leave these two on the auto settings with the XMP profile enabled, the Bios is showing me (what I understand to be) quite high voltages for these - around the 1.33 volt mark. The XMP profile sets the DRAM voltage at 1.35.
3. Benchmarking using Realbench 2.56 is throwing up some results that are a bit confusing for a novice like me. The GIMP image Editing test is showing a score of around 200K and I understand this test focuses on single threaded and memory performance. On the other hand the Handbrake video compression test (which I understand looks at multi-threaded performance) is giving me numbers around 92K. Is this just a function of the numerical scale used for the two different tests or is something going wrong with my multi-thread performance? At this stage, I am not too fussed about the absolute scores. I am just wondering if the disparity between the two scores is pointing to a problem. I have run the benchmark test dozens of times and in each case I have set realbench.exe to realtime priority in task manager for the sake of consistency. Any advice gratefully received.
4 Finally, just a very nooby question regarding setting the voltage to adaptive at the end of this process in the current Bios. When I select the "adaptive setting" it gives me the box to plug in a voltage (the manual setting plus 0.01 or 0.02 volts right?) but that option also leaves up an option to plug in an offset value. Do I leave this on "auto" or should I be plugging in a minimum value of 0.01v here?

Many thanks to anybody who waded through the wall of text above and I would be very grateful for any advice or insights.
Wishing everyone a safe and prosperous 2018.
