Hey everybody, I built my PC in March. I decided I wanted to overclock today, after it has been running smoothly for all these months.
Specs:
Today, I messed around with an overclock. I changed the CPU to 47 (so 4.7GHZ) and it ran pretty nice. I benchmarked and it was pretty stable. Then I upped it to 50 (so 5.0GHZ). I had my voltage at 1.35 at first, but that was getting very hot (90C'+ with AIDA64 Extreme Stress Test). So now, my current overclock is 5.0GHZ with a 1.33 voltage. Any lower and I got BSODS.
Anyways, I used AIDA64 to stress test it, and after 15 minutes it only had 1% thermal throttling. It hit like 96C though I think.
I tried using Prime95 to stress test it tonight and when I use the Small FFTS option, the test does not even work:
I am wondering why it is saying hardware failure instantly after beginning the test. My PC was running pretty stable. I played GTA 5 for like two hours and the CPU wouldn't go over ~70ishC'.

My CPU just gets kind of hot when I first boot for some reason, probably the spike in CPU usage.
Please help me, thanks
UPDATE: I just ran another stress test with AIDA64. 5GHZ / 1.33 volts. Went downstairs to make a nutella sandwhich, and when I came back up after eating my PC screen was black. My liquid cooler was flashing the default rainbow color, so I guess that means my PC just completely froze? My keyboard and mouse were both frozen. They are usually fading through colors, but it was stuck in some middle sequence. Had to hold down the power button on my PC, and it completely shut off. But the lights were still on on my peripherals... I had to completely turn off my rig from the power button on the PSU, and 3 seconds later my peripherals turned off too (finally).

I am wondering why it is saying hardware failure instantly after beginning the test. My PC was running pretty stable. I played GTA 5 for like two hours and the CPU wouldn't go over ~70ishC'. Also, I was playing Overwatch for hours and the CPU wouldn't get very hot either. As of right now, while typing this, the CPU is 40'C and my GPU is 40'C as well.
Why is Prime95 doing this? Is my 5.0GHZ/1.33V overclock stable? I really want to get the most out of my system, so hopefully you guys can help me get a stable 5.0GHZ overclock.
P.S. When my PC was getting very hot, the AIO was having an issue where it would flash red. I am assuming that the red flashing indicates that it is too hot, so that's why I dropped my 1.35 voltage to 1.33. Also, I tried 4.9Ghz with 1.32 and it was semi-stable. My CPU just gets kind of hot when I first boot for some reason, probably the spike in CPU usage.
Please help me, thanks
UPDATE: I just ran another stress test with AIDA64. 5GHZ / 1.33 volts. Went downstairs to make a nutella sandwhich, and when I came back up after eating my PC screen was black. My liquid cooler was flashing the default rainbow color, so I guess that means my PC just completely froze? My keyboard and mouse were both frozen. They are usually fading through colors, but it was stuck in some middle sequence. Had to hold down the power button on my PC, and it completely shut off. But the lights were still on on my peripherals... I had to completely turn off my rig from the power button on the PSU, and 3 seconds later my peripherals turned off too (finally). Anyways, when I reopened AIDA64 it said that it was terminated unsuccessfully, and the maximum reported temperature was 98C (wow...). So does this mean my chip is not capable of hitting 5.0GHz?
