Just done my Z390M. Had a slight oddity with the driver, but otherwise went OK.

Updated motherboard BIOS, reconfigured BIOS and enabled new PCIe feature

Installed 465.89 drivers

System Info shows Resizable BAR No (as expected)

Updated GPU firmware and rebooted

System Info no longer lists Resizable BAR at all (rather weird)

Re-ran GPU firmware tool which confirms update has applied OK

Re-installed 465.89 drivers

System Info now shows Resizable BAR Yes (nice)

Thanks

I take it you flashed the beta bios?
If I turn on the re-size. It won't boot

Confirmed that everything seems ok for me.

Aorus X570 Elite (BIOS UPDATED to F33g)
Changed required settings in BIOS (4g etc etc)
Updated to nvidia 465.89
Flash VBIOS on Gigabyte 3080 Gaming OC from F1 to F3
resize BAR = enabled

Literally did it this morning, so I haven't had time to check on any of the advertised FPS gains.

@LtMatt will surely be pleased! *rubs chin*

I don't use a Nvidia GPU Thot, so whether it's a 1% or 10% increase makes no difference to my gaming experience.

As i mentioned though, I see 8.5% at improvement at 4K and 10.9% at 1080P with SAM in this title.

I don't think that user has even posted a score in the thread (which would be required) but it wouldn't be enough to take 1st place with a 5% increase.

My Gigabyte Aorus Elite X570 MB bios has had resizable bar support for a while. Turned it on last night, updated the graphics drivers and ran the Nvidia bios patch for my 3090FE.

All seemed to go fine. Now shows up as enabled in the Nvidia control panel. Haven't noticed much of a difference, but my 2D gaming is at 1440p. It's VR where I really stress the 3090 and I don't see any VR games supporting it yet.

If you have no display, after flashing DISABLE CSM in Bios

Compatibility Support Module probably was enabled, you need to disabled it.

So this is safe right, nobody has bricked yet?

yeah no brick on my end with b450 and 2700x. though i feared for the worst, since i enabled it with an unofficial unsupported processor :eek:

Toothy1911 · 31 Mar 2021 at 09:33

Always a chance to brick if the flash doesn't go well...

Yes, beta BIOS. System is configured for UEFI only with Secure Boot enabled (no CSM).

Your may run into issues if your main drive is MBR rather than GPT and you disable CSM.

Always the same, must have a latest greatest product (mobo & CPU) for it to be compatible with

. So no joy with a 9900K

Working fine on my 9900 and 300-series board. Check you MB manufacturer for BIOS updates.

You may be out of luck if it is Asus though. They are being ducks.

Okay, will keep an eye out but nothing there yet (Asus Z390 Hero Xi). Also didn't see Z390 or 9th Gen CPU's in NVidia's list of supporting products but maybe the list is just not complete.

Probably more to do with marketing current hardware and making it all sound new when it's really not and has been around a long time but never utilized.
