overclocking Unstable OC, pls help. 1800x

[HypeTrains]

I set my voltage to 1.375 and the clock to 3900.  (also happens at 3800).  I'll run cinebench once, then I'll run it again and my screen goes black and my peripherals disconnect.  I hit the reset button when this happens.  I am trying a higher voltage but it still crashes like this so far.  I don't want to go to 1.4volts.  I am pretty sure it's not thermal crashing because I don't get any throttling.  Also, after the first crash, the crash will happen early in the benchmark every time.  The reason I am writing this is because my pc crashed out of nowhere while I was chatting on discord.

 

I have tried 1.4v on 3800Mhz and it's still crashing.

 

UPDATE: anything other than stock is crashing in cinebench.

1.4v is still fairly safe for Ryzen. You might not be able to get much further if it crashes at 1.4v at those clocks.

I boosted it to 1.3975 and so far on 3800mhz it's doing good.  I'm gonna keep experimenting.

Edit: I have done 2 successful benchmarks on that volt&clock! yay!

Nice, that's not too bad. 3.7-4.0GHz is the usual average for most Ryzen chips; anything higher, especially under 1.4v is a golden chip.

nvm it crashed on 3rd time.  I'm trying 1.4v now.

 

EDIT: crashed second time on 1.4v 3800Mhz

your motherboard vrm is probably limiting your oc, the 1700/1800x starts drawing exponentially more power after 3.7 (hence a possible wall after 3.8 depending on mobo), if you can lower it to 3.75, it's probably very smooth and efficient.

so I just finished testing, literally everything other than stock crashes.  Is this a mobo issue or could I have hurt my processor?
