3090 Strix OC White Mobo Light on Cold Start (even though it runs fine)

[martine-dee]

Ok because on my PC I had a problem, I was getting this white led when I tried to put the re size BAR in bios, I disabled the CSM module in the BIOS and every time I had this problem of led, with an update of the Vbios this has been resolved, but it does not seem to be your case here.


EDIT: however you can see if a Vbios is newer than yours here : https://www.techpowerup.com/vgabios/

Or ASUS: https://rog.asus.com/fr/graphics-car.../helpdesk_bios

Handy site!

The VBIOS I have is 94.02.42.00.A9. Alphabetically, it seems to be the highest one for Strix OC as well.
And, yeah, I got it from Asus' support page for my card.

I get this white light on my motherboard Dark Hero and strix 3090 OC . It happens when you boot the system up before the monitor is available. On my Asus PG35VQ if I wait for the displayport no signal light before I turn on the pc no light system boots fine. Turn the system on then monitor and white light. Deep sleep being enabled on display will cause this as well.

Magic!

This works. If I make sure that the monitor is awake before I start the PC, the white light doesn't stick.

Goly!

Cheers, it annoyed me for a short while as well. Harmless indication but really annoying if you have a glass side panel and use your pc in the dark.

Finally solved. Happy for you.

Yes, it is eye-searing. And also worrying without the knowledge of what is causing it.

Tyty! ^^

Next update.

On the monitor side (PG259QN) this is down to the DP deep sleep option. I might have selected it to save energy, but instead, it made me double-start my PC every time I start it before this topic. Probably not worth the cost. I switched that off and things just work now.

Another solution, which I wouldn't do is either tape or remove that painful white led.

What ASUS could do is add an option to make the motherboard not react to that.
