Resizable BAR support for X299

Hi badaz,

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.

Hello,

I tried again today, having previously flashed the 2.00B BIOS you sent me, but I cannot find a set of parameters that does not result in the 5 beeps when C.A.M. is enabled in BIOS.

Here is my config :
- Intel 7740X (Kaby Lake X)
- Asrock X299 Killer SLI/ac (BIOS v2.00B, the one you linked)
- MSI RTX 3080 Ventus 10GB OC (VBIOS 94.02.42.00.2B with ResizableBar capability - see GPU-Z screenshot)

BIOS settings :
- CSM : disabled
- Above 4G : enabled
- C.A.M. : enabled

I still get the 5 beeps and no display. I also have to clear CMOS in order to get my display back.

I tried plugging my monitor into every GPU outputs in turn (DP 1, DP 2, DP 3, hdmi) but the machine still emits 5 beeps and nothing more happens.

Is there any known bugs with this beta BIOS?

The system can boot up and working fine with C.A.M enabled. Here is our test config: 7820K X299 Killer SLI/ac 2.00B MSI RTX 3070 Ventus 8GB OC with resizable-bar vBIOS We recommend contacting MSI to check if they have any advice about this question.

Hello, I just got an answer from MSI support who told me that this GPU (MSI RTX 3080 Ventus 10GB OC) with this VBIOS (94.02.42.00.2B) was fully compatible with ResizableBar, and that I should ask Asrock support... Well, if you do not have an MSI RTX 3080 Ventus for testing then I guess I'm screwed until you have one?
