Testing please: GPU-Z Resizable BAR Support Report

W1zzard · May 16, 2021

I added a detailed PCIe Resizable BAR report to GPU-Z -> Advanced Tab, or just click on the Resizable BAR readout on main screen.

Beta build is attached to this thread. Not 100% sure yet if I got all these detections implemented correctly.

Could you guys test this on your systems (with and without BAR enabled/support) and let me know your thoughts?

I've removed the attached test build from this post. Use public GPU-Z 2.40.0 instead, please.

I've got an RTX 2080 SUPER and get this:

See specs for the rest of the system.

Does that list look accurate?

95Viper · May 16, 2021

It works for me... the Motherboard manufacturer on my z490 board has not put out the Bar BIOS... supposed to be in the works.
So I wait.

Well, I don't know what every setting means, so here goes:

GPU hardware support - correct
Above 4G enabled - no idea what this means
Resizable bar enabled in bios - correct. Neither the mobo nor the GPU support it
CSM disabled - no idea what this means
boot from gpt - correct
64-bit OS - correct
Windows running in UEFI mode - not sure. The mobo's got a UEFI BIOS, but it's a 2011 product running a 2700K, so maybe W10 has switched to pre UEFI mode. The UEFI is not in legacy mode and doesn't have one
Graphics driver support - not sure. I have the latest driver installed, so it depends on the context, ie it won't support it on this hardware, but will on the right hardware

Hope this helps.

run msinfo32, look for "BIOS Mode", that shows "Legacy"?

Right now the logic is to show "driver: no", if the currently installed driver has no resizable bar support for your GPU (2080 Super).
The driver does have support for Resizable BAR on Ampere GPUs.

Better to show "yes" in this case? Not sure

Mussels · May 17, 2021

First screen says enabled, second screen says disabled in BIOS?
I also have CSM disabled
For clarity, all these should say YES

hardware as in specs, BIOS is:
ROG STRIX X570-F GAMING BIOS 3801
AMD AM4 AGESA V2 PI 1.2.0.2

AsRock · May 17, 2021

shows up for me how it should do, as i do not have a card that supports it so, but it's there.

And back off

What is Above 4G Decoding – your BIOS's dark horse. Should it be enabled?

In modern motherboards BIOS, you can find the Above 4G Decoding checkbox, and now the Resizable Bar has appeared next to it. And the Resizable Bar was already well explained by AMD – the processor can directly communicate with the card through a couple of big steps, instead of a million tiny...

im on Z590 mobo and bar enabled in bios with bar enabled drivers.

qubit · May 17, 2021

@W1zzard I'll get back to you this evening re that command.

EDIT: re the driver, I'd show it as "Yes (disabled)" on hardware that doesn't support it, like mine. Waddya think?

W1zzard · May 17, 2021

"disabled" doesn't mean "not supported", even "not supported" doesn't mean "supported by this driver version for other GPUs, but not yours"

X800 · May 17, 2021

I have the same issue that Mussels have.
Bar enabled and CSM disabled they should be yes.

w1zz got some info from my system, he's working on that issue

Shou Miko · May 17, 2021

I will test this with my AMD setup when I get home and see if it still works :peace:

W1zzard · May 17, 2021

Build in first post updated with fixes for CSM and BAR detection

@X800, @Dorek can you test the new build?

Dr. Dro · May 17, 2021

ayy, it's also misreporting for me. Running driver 470.25 on Windows 21382.1.

BIOS settings are:
Above 4G Decoding: Enabled
Resizable BAR support: Enabled
CSM: disabled

GPU is updated/flashed with Resizable BAR capable BIOS

Edit: Ninja fixed with the build you just posted, nice one w1zz! Just need to take care of the CSM disabled thing now

Solaris17 · May 17, 2021

Resizable BAR in the BIOS is enabled, but its a beta feature for this board currently, so that might be par for the course.

Everything else looks correct, I always enable above 4G.

Well, it's the context, isn't it. I think it's clear enough that the driver supports the feature, but not on this hardware, without resorting to a long sentence. Perhaps you could have a little question mark next to it which brings a popup with a verbose explanation of what's meant by that? If you can think of a better way to put it, then I'm all ears.

I mean, is "disabled" and "not supported" literally not clear enough?

The context is different, isn't it? He was wondering how it should be phrased so I've made a suggestion. He can put it anyway he likes and if he, or anyone else has a better suggestion, then I'm all ears.

I somehow get your point, I suppose adding a row stating the reason Resizable BAR support cannot be enabled would solve this standoff and make it more accessible for people that don't know what these settings mean, and then adjust the other entries to be as accurate as possible (for example, Graphics Driver Support: "Yes").

For example, if Pascal or Turing are detected, the row would say "Not supported by GPU architecture", and if system requirements for the feature aren't met, it could say "Not supported by current hardware configuration, please ensure the Compatibility Support Module (CSM) is disabled and that Above 4G Decoding, Resizable BAR support are present and enabled in the system BIOS" or something.

Yes, nicely put, especially your second paragraph. Two heads are definitely better than one when it comes to things like this. :toast:

Nice idea, but every single item of the "Yes" list must be "Yes", or no resizable bar. so if multiple are "no", that would complicate the text a lot

Like on my work system:

Works like a fine on my system and thanks @W1zzard

looks the same except CSM disabled is yes, which i think is correct actually.
