Need 9700k Overclocking Input

[JB780]

I've got my 9700k on a Aorus Z390 Pro being cooled by a Corsair H100i PRO.

 

I decided to shoot for the stars and started my OC at 5.1 Ghz, initial voltage of 1.3. I used Cinebench 15 as a quick stability check, I got a BSOD until I increased the voltage to 1.33. At 1.33 I was able to run Cinbench & Time Spy with pretty solid results, but when I moved onto Prime 95 my first few attempts failed almost immediately.

 

In Prime I ran the smallest FFT test and disabled AVX, I have an AVX offset of -3 set in my bios. After increasing the voltage by .01 after every failure I got up to 1.35 volts and failed again. At this point I decided to run a Prime test with AVX on, it started running fine as my CPU went to 4.8Ghz but the temperatures were starting to touch 100C so I stopped the test. I then ran another test with AVX disabled and for some reason this time it ran for 20 minutes at 5.1 Ghz and 1.35 volts before BSOD, the temps were fluctuating from the mid 80's to mid 90's. 

 

From what I can see, keeping the 9700k under 1.4 volts and 85C is ideal, should I keep pushing forward on the voltage to see if I can get it stable in Prime or just accept that I didn't win on this chip and dial back the clock?

I know it's not stable if I'm crashing in Prime95 but if I only use this PC for gaming and I can get great results in bench marks, should I worry less about crashing in Prime?

If this is going to be your everyday overclock, I would recommend trying to make it as stable as possible.
