Unstable overclock? (i7 4790k)
Unstable overclock? (i7 4790k)
I don't understand the problem with my overclock (4.6 @1.26v).
It passes stress tests like prime95 (I know prime95 past 26.6 isn't that impressive for such tests) and realbench, but I experience random crashes when browsing things like YouTube or Twitch. It's not a BSOD just a complete crash.
After stress testing yesterday, I decided to play games on it to check for issues and didn't have any problems. I played CSGO, Fortnite, GTA5, and Arma3 without any issues. It seems the crashes are completely random. What might be causing this?
I'm very new to overclocking, so maybe there are other BIOS settings I missed. From what I know, I only changed the core voltage and clock speed, setting it to override instead of auto.

My computer just crashed again (no BSOD). I increased the voltage twice more—from 1.265 to 1.27—and did a stress test. It passed, but I still experience random crashes even when the system is under minimal load. I only had Chrome open while checking my email. I’m not sure what’s going on and need some help. At this stage, should I keep adjusting the voltage? My PC was stable at 100% load with 1.26, but now every time I get these random crashes, I raise it by 0.05, hoping it will fix things.
You mention it simply stops functioning without any error screen, and does this consistently each time you launch crome or twitch.
OCD Tweaker:
you mention it works well, just stopping the BSOD without any issues. This doesn’t occur every time I open Chrome or do anything else—it’s random. It’s happened around four times so far. Twice when I was idle on my PC and twice while using Chrome. It just causes the screen to go black and restarts my computer.
I also ran a one-hour stress test with these settings, which resulted in a black screen, but it passed.
It's happening because your system is running on a 2-core processor at 80°C, and core 1 is also reaching that temperature. The computer will shut down if it gets too hot unless you disable this feature. This isn't the issue I described—it was completely random crashes. I tested for an hour without any problems. When crashes did occur, system load stayed below 0. My idle temperatures range from 24 to 30°C, depending on outdoor conditions. The CPU never approaches 80°C unless I deliberately stress test it.
