X40 rtx4090 - white screen crashes.

Hi,

Having issues with white screen crashes during gaming. updated the BIOS to the latest version on the website to 1.23. How do i update the EC? 

I'm not sure if the crashes are CPU related, when i monitor i am at 30%load during gaming and it runs at 91c. Anyone experienced this?

If it is the Intel CPU issue then I'd recommend putting the laptop in office or quiet mode, keep pushing the button next to the power one. 

Then hope that the CPU hasn't been cooked by too much wattage. 

Open up the command center app, I think power. Performance tab, create a new power profile.

There is a CPU temperature slider, I think mine was set at 95°c put it down, 75 was the lowest for me, the 4090 don't run as hot a the CPU. I scrolled down and clicked turbo fan which put them at 100%. While playing cyberpunk maxed out it was a much better experience. 

Do that, play some more of what ever your doing keeping an eye out for white screen crashes, hope they've stopped & permanent damage hasn't set in. 

I'm investigating the pl1 pl2 & pl4 power settings, the command center app doesn't seem to be documented so I'm trial & erroring it. 

I'm pre the Intel CPU issues & trying to keep it that way.  Don't let the CPU tun hot.

Hi Thomas,

I've done what you recommended. Hopefully that's worked around the issue! I tried to manage the cpu power but in Windows initially but it had not worked. 

Many thanks.

Unfortunately the issue wasn't resolved with above. I checked windows event viewer and this was the only warning that was generated prior to the crashes which always seemed to occur just before the crash.

Found a possible issue that others have had and turned the below 'off' to test. I lasted 2 hours in metro exodus on performance mode.

Its worked for other people, but yet to confirm if it is a permanent fix.

I hope you've found a fix, I really want to see those screen shots I'm proper intrigued.

[brad87]

It looks like the screen shots are not going to be approved anytime soon.

If you go to System > Display > Graphics > Default Graphic Settings.

There is a setting for hardware accelerated GPU Scheduling. I just turned this off and rebooted the laptop.

How's the stability holding up?

I've tested that to, turning it off also stops nvidia's frame gen from working in cyberpunk, it flips over to amd's version not allowing nvidia's. 

So I've turned it back on.

Unfortunately after around 6-7 hours I had a crash. I think I'm going to contact support regarding the issue now as laptop still in warranty. 

I've read a post where the xmg bios was super stable for this laptop. If your laptop out of warranty.
