[GPU-Z Test Build] Resizable BAR shows as "Yes" when Supported but Disabled

W1zzard · Apr 6, 2024

Please test and feedback

R-T-B · Apr 6, 2024

No diff on my egpu box, sorry to say:

StefanM · Apr 6, 2024

Changed from enabled to disabled on my laptop GPU (HWiNFO64 claims enabled).

EDIT:
after a second launch 2.58.1 reads enabled again :confused:

Can you check if 2.56 always shows the correct status?

2.56 looks OK

I can reproduce the issue with 2.58.1 when i switch to the iGPU (which is always disabled/unsupported) and quit.
Next start shows dGPU disabled again.
Quit 2nd time and run again and dGPU shows enabled.

Im not sure if its appropriate but it does show as enabled on my test system with eGPU but eGPUs dont support rebar so it isnt working.

Tried it with both 2.58 and 2.58.1. Disabled resizable bar, and it reports disabled on both, with a 2M BAR1.

2.58.0

2.258.1

2.58.1 shows Disabled for me when disabled in BIOS.

2.58.0 shows Resizable BAR as YES when disabled in BIOS. (same configuration as above)

I'm away from that machine until evening but will get back to you.

Rebar Off in Bios:

Thanks! This means 2.58.1 works correctly on your system, right?

:D:D · Apr 9, 2024

Well...
I will have to make some assumptions with 2.58.1 so could be wrong here especially as I easily get confused these days.

1. "Resizable BAR Enabled/Disabled". Seems dependent on BAR address size, but actual BAR size can be smaller and the definition of enabled with GPU-Z seems to be if the address size is above 512MiB it's enabled. Example with actual BAR size 64MiB but addressing greater than 512MiB.

2. "Above 4G Decode enabled in BIOS". Can be disabled in BIOS and addresses reallocated after POST. (Semantics?)
3. "Resizable BAR enabled in BIOS" may be no option in BIOS but again can be done after POST (Semantics?). This function seems dependent on actual BAR size being greater than 512MiB.
4. "Graphics Driver Support" don't know where this comes from, hard coded or not?

These observations not really relevant for possibly millions of people but FYI.

works fine with my xtx hellhould

New build attached, please test

No improvements yet for Optimus (StefanM) and eGPU (Solaris, R-T-B, still waiting for those resource screenshots)

Solaris17 · Apr 13, 2024

This is through a GPU enclosure. So no rebar.

Sure thing, the scroll bar makes it looks like there is more, but there are only the 3 entries shown.

W1zzard · Apr 15, 2024

New build which should work correctly on eGPUs, too. Still no solution for Optimus

W1zzard · Apr 18, 2024

New build, please test and feedback asap so I can push out a new release this week.

This should work correctly on all setups, including sleeping Optimus GPUs and eGPUs

StefanM · Apr 18, 2024

Looks OK now on my Optimus rig.

Have you tried a couple of times? just to make sure the GPU is really sleeping when GPU-Z checks?

Very sorry, that whole PC had to undergo a reinstall after a malware incident courtesy letting a younger member of society use my PC (Free minecraft lessa go! /s)

I'll grab you it in a few seconds here.
