CSM (Compatibility Support Module) resets to enable / can't disable it

[Fdrph]

I have windows installed on my SSD in UEFI mode but I can't disable my CSM.
When I reboot it goes back to enabled automatically and this is driving me insane.
I also have an external HDD (USB) that takes time to initialize and makes my POST last a long time and I want to tell the bios to ignore it and let windows handle it, but i dunno how to do this.

thanks in advance ;3

Hi!

Have your read this manual: (?)
http://rog.asus.com/220572013/rampage-motherboards/rampage-iv-uefi-boot-installation-guide-on-window...

Hope this helps.

yes I have and I dont see how it could solve my problem. In that guide it is said to disable it. I do it, it enables itself again.
and I also followed it while installing

Hmm - I did some search - Maybe this forum thread can help you out!

reading that I can deduce that the problem could be the GPU.
I have a sapphire 7970 reference but there is the possibility that it is not native to UEFI which is weird.
I also have a soundcard... dunno if that could also be the cause.

Anyway I'm not sure there are UEFI bios flashes available for the 7970

seems asus is aware of this...
but my card isn't asus it's sapphire what should I do?

#FIXED CSM NOT STAYING DISABLED
Ok so I ended up flashing my 7970 reference sapphire bios to an ASUS bios with UEFI support

asus bios acquired from this user on overclock.net http://www.overclock.net/t/1389206/do-you-want-uefi-gop-on-your-7950-7970-i-can-add-it-to-your-bios/...

CSM keeps itself disabled and fast boot with UEFI works much better now 😉
However I think sapphire is really behind since i had to flash my GPU with a bios of a different manufacturer! Guess i should've bought ASUS haha


so yeah to anyone having problems it's probably your GPU if you have UEFI windows 8 installation already!! check your manufacturer for UEFI bios updates!!

Awesome that it worked to fix the GPU Bios! Thnx for the update and information 🙂

I've always gone with the Asus cards because they keep their stuff up to date and have a good warranty!
Also it seems like they have the most "silent" cards right now 🙂
