Resizable BAR support for X299

Hi.

I would like to request an updated BIOS for adding Resizable BAR support (or C.A.M.) to the X299 motherboard lineup.

Currently, ASUS, EVGA, MSI, and Gigabyte have recently begun adding support to their X299 boards, and it would be a welcome addition to see Asrock do the same for their X299 motherboards, and would go a long way in keeping the HEDT platform current.

For reference, my motherboard is: Fatal1ty X299 Gaming K6


Thanks.

Hi Gamer313,

Thank you for your post.

Please update the BIOS P2.00B for the CAM function. The BIOS file's download link is as below.

After updating BIOS, please follow the instructions below to enable "CAM".

1.boot into BIOS and go to the "boot" page, then go to "CSM"
2.Disabled "CSM"
3.Go to Advanced\chipset configuration, then enable "Above 4G" and "CAM"

Please make sure you are using the AMD RX6000 series or the NVIDIA 30 series with the vBIOS which supports Resizable BAR.

I linked the instant flash SOP as below.

All the best,

Never mind.

The bit after the last '/' needed to be removed.

Link works fine.

The C.A.M. option doesn't show up if 'Fast Boot' is enabled.

My understanding was that 'Fast Boot' didn't use CSM, and since 'Fast Boot' hides the CSM option, it cannot be disabled.

Otherwise, C.A.M. works as expected.

I do not have the same motherboard as you. However, I'd like to know Asrock's stance on the subject, juste like you, since I own an X299 board as well, the X299 Killer sli/ac. Please Asrock? Could you tell us what your plans are for the other X299 cards for which there is no Resizablebar enabled BIOS available yet?
