X299 Big Sur Support

Yeah ResizableBar should work. I have it enabled on my 7900X in my Rampage Encore build

Obviously you mean in Windows, right mate?

Yup only works in Windows for now. My Rampage isn't hacked anymore

Make sure you update your BIOS/vBIOS/and video drivers for Resizable Bar support.

Hey Everybody, I saw this in the BIOS Setup list:

5.) /Advanced/System Agent Configuration/
a.) Intel VT for Directed I/O (VT-d): Disabled/Enabled

So, am I supposed to pick Disabled or Enabled? I just left it on Enabled.

Any help would be appreciated. Thanks again, guys!

Hi all,

I have a question about X299 motherboards.
As of today which is the best option as X299 motherboard?
Is the Gigabyte x299x Designare 10g rev 1 a viable option or not?

Thanks a lot.

Intel VT-d can be enabled in the bios if the OC quirk DisableIoMapper is set to True.

I changed my board to a Asus Sage x299 10G because it had NVRAM support. I'd look for a board that has this ... just makes life so much easier.

I did use once the Asus Sage x299 NON 10G model. Great board.
BUT it has one ridiculous flaw. No USB 2.0 internal header for the broadcom native bluetooth. I had to connect it through some funny internal hub or routing external USB 2.0 ports.
Does the 2 x 10G Ethernet works well?
It also doesn't have integrated Thunderbolt 3.

How about the PRIME X299-DELUXE II?
- Does Thunderbolt 3 work well?
- Does the Aquantia 5Gbps LAN work well?
- Does the integrated Intel WiFi work well replacing the broadcom?

Thank you. Forgive my ignorance, where would I find the "OC quirk DisableIoMapper" to change it to "True?"

Well, After installing the 6900 XT, I'm experiencing issues with startup as it's constantly giving me:

CODE: 20 Detect Memory

Now I know I don't have any issues with my memory, as it's been working fine before. So does anybody know what the issue might be? Could it be a BIOS setting that isn't set correctly? I've tested out each stick of memory on my identical backup system and every stick of RAM is working just fine.

In the meantime, I have to force shut it down and restart and then exit BIOS without saving to get it to start up properly each and every time. I hope there is a way around this. Any help would be appreciated. Thanks

set: Kernel -> Quirks -> DisableIoMapper to True in your OpenCore config.plist.
