Undervolted CPU causing my crashes

Hi Blueberry,

Can absolutely confirm this was the root cause of my crashes.

Under constant load using Cinebench and Prime95 there was no crashing but when there was a sudden call on the CPU in game the voltage on the CPU was actually dipping below 1.2v on the vcore to around 1.17v.

After putting it back up to 1.3v(stock is 1.34v) in the bios haven't had any dip in voltage or a single crash in game since.

are you crashing to desktop or is your entire PC crashing?

This is still not a problem with your system, the problem is their bad optimization. The game is using AVX instructions and they probably messed up something in that department.

I have the same issues and I "fixed" the problem the same way. Actually I didn't bump up my vcore, instead I lowered my overclock by 200mhz, the end effect is the same.

If a system s 100% stable in numerous stress tests and all other games (including BF5 which also uses AVX instructions) then it should also run Apex with ease. I really hope they fix this so people can revert their rock solid overclocks once again.

I completely agree with you. I have a 7700k running stable on 1.344v, I don't feel comfortable enabling AVX or bumping up the voltage, I have an MSI board and this CPU was a hard one to get stable on this board. I would say that my system is 99% stable (sometimes when the PC is not in use for a few days the OC resets and then is automatically backed up) but it never failed when active. 
We should have not supposed to tweak our builds to play the game, this needs to be fixed asap.

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.

THIS RIGHT HERE! It doesnt make any sense that other applications, benchmarks, tests, games, and services perform flawlessly. It is 100% Apex that is the problem. I also don't see how voltage is a problem because if it were then wouldnt it blue screen from being undervolted? 

I am going to try to run an "Apex specific" OC to see if I can narrow down what it likes and what it doesnt like. It could be the frequency on  the CPU or RAM but idk... you shouldnt have to nuke your OC just to run the game. That is stupid. 

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

EDIT: 

Also, this was a non-issue for me prior to the most recent patch. I would very rarely drop a game. Maybe 1-2x a week (if that)  till season 1 came out. Can anyone else relate to not having issues prior to the most recent update?

Would'nt necessarily BSOD if the undervolt was causing the CPU to have issues with the instructions from the game (from memory to CPU to GPU transfers). Would only BSOD if it could'nt handle instructions from the OS.

(Hence why BSOD can still operate by backing up memory).

As for running an Apex specific OC, exactly how much speed are you gaining from your OC that not OC'ing your PC is a problem. What 3-10fps from your overclock?

I'll risk losing 3-10 fps for a stable game any day. (the 2080ti is giving me good fps so .... meh)

But I will say it one more time. Undervolted the game kept crashing, stock voltage the game runs like a dream.

i edit video and audio. my rig isnt solely for gaming. so the * of losing my OC just to game is meh
