Seems like you have kind of a lame i7-3820 that needs a bit more Vcore than most do at that frequency..You can check out the
i7 3820 - 4820 Overclock Club (and other places) to see what Vcore others are needing at various frequencies.
The
VID Voltage Range has a maximum of 1.350V which can be what some of those need just to run at stock frequency.
The TjMax (throttling temperature) temperature is 100C for that CPU.
I wouldn't worry about the motherboard, it'll probably let you apply way more Vcore than you have now and be fine..The CPU is of more concern..You should also be running the latest BIOS for your motherboard which may include stability and other enhancements..VREG and System temps are usually rated up into the 90C neighborhood.
I would run the
Intel Processor Diagnostic Tool stress test or a pass of
IntelBurnTest for quick stability testing and adjust your Vcore down until it fails, then bump it up a notch or two..Roll from there.
Nobody can say how long your CPU will last at that Vcore..
Is overclocking safe? What you can do to reduce wear and tear and increase the CPU life is to enable C-States and Intel SpeedStep (especially) in the BIOS, which they should be by default..And use the 'Power saver' plan in the Windows Power Options..No sense in running your CPU at full blast all the time when it's not neccessary.
You should be sure that Temperature Monitoring for the CPU is enabled in BIOS too, which it should be by default, otherwise it won't throttle at TjMax.
