Undervolted CPU causing my crashes

I'm not really understanding both your replies.

My vcore was badly undervolted due to an issue with a bios update that actually lowered the vcore below spec. Before the bios update the vcore was 1.34v, after it was 1.2v. I didn't "up" the voltage but set the voltage to the i7 9700k stock voltage.

It's not bad optimisation if you "fixed it the same way" by removing an overclock. Thats running your PC over spec and the system crashing.

Comparing BF5 and Apex is like comparing apples and oranges. Both use a different game engines and have different levels of CPU/GPU usage.

Regardless, making sure everything was running to spec in the bios was how I fixed my issue. Might help someone else.

Well the problem is that you obviously have little experience with overclocking. The ~1.2v is actually a common stock voltage for 6th to 9th Intel mainstream CPU's, the BIOS that's pumping you ridiculous 1.34v stock voltage is the one with an issue...

Ad no, it's not "running the system over the spec". If everything else, including various stress tests, applications and a ton of old/new games are running with no issue at all then the problem is obviously in Apex optimization.

Were you at a weird frequency when you dropped 200mhz? Did you touch your RAM at all?

The frequency was exactly 200mhz lower, from 4.9ghz to 4.7ghz. However the game is using AVX instructions and if you set an AVX offset in the bios the frequency will jump up and down each time an AVX instruction activates. I tried out setting frequency to 4.9ghz with an -2 AVX offset and the frequency was jumping from 4.7-4.9ghz. This is also a workaround, you can try to set an AVX offset, this way you will keep your old overclock frequency and it will be lowered only in games/applications that use AVX instructions.

My RAM and GPU are overclocked and as long as I keep my frequency at 4.7ghz there are 0 crashes and I'm talking about weeks of playing.
