Computer randomly crashes after undervolting CPU

I undervolted my stock 8700k by -.105v.

 

Now my computer crashes occasionally. I understand that this is caused by the CPU not having enough power, but I saw a lot of people online under volting their 8700k alot more than .105v. Does that sound like it would be substantial enough to cause crashes?

 

Anyway, I changed it to .9v. So we will see if I get another crash. Let me know what you guys think about this.

Silicon lottery winners and losers, not every CPU has the same behavior at a given voltage.

I WILL find your ITX build thread, and I WILL recommend the SIlverstone Sugo SG13B

 

Primary PC:

i7 8086k - EVGA Z370 Classified K - G.Skill Trident Z RGB - WD SN750 - Jedi Order Titan Xp - Hyper 212 Black (with RGB Riing flair) - EVGA G3 650W - dual booting Windows 11 and Fedora Linux - Black and green theme, Razer brainwashed me.

Draws 400 watts under max load, for reference.

 

PSU tier list

How many watts do I need?

I don't have a 8700K, but what has helped me with undervolting my 2700X is using load line calibration in conjunction with my undervoltage.  That might be worth looking into to see if it helps stabilize your undervoltage by preventing droops below your goal undervolt.

My computer just crashed again after having it at -.09

Did you try using load line calibration?
