ASUS Rampage Extreme IV Asus Fury Strix UEFI Problem

[LongBanana]

Hello Asus,

i have buy two ASUS Fury Strix last week, I'am very happy with this Cards.
My Problem ist that i can't boot in UEFI Mode, BIOS shows on boot that the Cards not Support UEFI.

Newest BIOS on Both Fury Strix:
7300HB.15.49.0.4.AS02
Newest BIOS on RE4:
4901

I test UEFI with this Cards on other Mainboards like RE5 and MSI Krait, UEFI works fine.

Please make a new BIOS for RE4, that Support UEFI with Fury Strix.

Thanks

Andy

Do you have CSM completely off in BIOS?

[LongBanana]

That's the Problem, with CSM deaktivate shows the BIOS your Cards not Support UEFI.
CSM anable and legacy boot, all works fine. No other PCI Cards in my PC.
With my old two 7970DC2T works UEFI CSM disable, like a charm.
I find other user with Fury Cards on Asrock boards with the same Problem, Asrock fix this with a new BIOS.

I think it is on the time for a new W10 ready BIOS for RE4, last BIOS is older than one Year:

newest EFI Intel ROM
newest iROG
newest CPU Codes
And Support for new UEFI Cards like Fury and GTX

Is the drive that Windows is installed on a GPT formatted partition?

This is not the Problem, i would like to make a clean install with W10. (newest build TH2)
It doesn't matter for a clean install.

With my old Cards 7970DC2T no problem, it is the mainborad BIOS.
On my other testet Bords i have no problems.

Ok, i have tested again:
No devices connect to the Mainborad. (SSD HDD USB PCI Cards)
CSM deaktivatet 7970DC2T boot fine, Strix Fury BIOS fail. (Video Card not support UEFI)

Additional test with other BIOS versions same problem. (older ASUS Versions)

Try my modded BIOS located here:. http://1drv.ms/1AwAvXz

ok, boot with second BIOS Version 4901
Your BIOS on a USB Stick, ASUS Flashtool says:

security verification fail

[BOLTS4BREKFAST]

Do not rename the BIOS file.. Leave it R4E.cap
Your BIOS settings will be reset after this.. So write them down if you need to.

Ok, thanks you for this BIOS.
but nothing Change, disable CSM beep four times reboot than BIOS say, VIDEO Card not Support UEFI.

what ever this Problem, with my 7970DC2T disable CSM works. ????????
