Should I stress test with LinX / IBT?

I've been overclocking my 6700K in the last few days. I came to the conclusion that trying to overclock over 4.6GHz will demand extremely high voltages to be stable. I tested it with 4.6GHz and 1.385V for 2 hours with OCCT – and it is stable with 65-75c. However, when moving to IBT or LinX, it reaches to 95c in the first 2 minutes and starts throttling. Gaming, however, seems to be pretty smooth. Should I consider my OC unstable or try another stress testing programs apart from OCCT?

BTW sorry for my bad English.

Thanks for answering!

It probably makes sense that the best way to check your OC is by testing it with every day use, problem is I don't always have time for long gaming sessions – which makes stress tests very useful to test stability. I often stress test for around 2-4 hours with several programs (like OCCT, Real Bench and x264), and when I get to a reasonable result I test it overnight. If it passes this along with my gaming sessions – I consider it stable.
What is the point of LinX and IBT if they almost never indicate real-time usage? Not that those stress tests either, but they are still reasonable.
Do you have any recommendation for another stress test?

Test, test, test, these people who dont bother to test there overclocks are the ones that post about games crashing, or having to re-format windows every few months, not realising that an unstable CPU overclock leads to an unstable memory controller, which leads to bad reads and writes to you ram and hard drives, errors and bad code written all over the hard drives.

I initially do some quick tests before I do the long tests, and im not happy until all are done.

so a quick run of Cinebench gives me initial stability, if it cant pass that, its not going to pass anything else.
50 passes of IBT standard settings, only takes 10 mins to run, gets the stress and heat right up.
50 passes of IBT Max settings for testing all of my RAM, takes quite a while to run, but 2.5 hours of this I find equivalent to running 16 hours of prime95.
Realbench benchmark test, is good for everyday use tests.

Overnight tests, I run AIDA64 stress test to start with, quite an easy one to pass to be honest, if you cant pass this, you wont pass anything else, you're very unstable and need more voltage or need to dial back on the speed.

Overnight, 8 hours max stress test of realbench.

Overnight 8-9 hours of Prime95 blend

Here's my test results so far, but only started overclocking yesterday, im running a Ryzen R7 1700 at 3.9ghz, on an MSI B350m Mortar Motherboard, with 16gb (2x8gb) G.Skill Trident Z RGB 3200mhz at its full speed.

The motherboard temp read outs in AIDA64 by the way is the MOSFET's

i prefer asus realbench its a much more real life usage tool
