[GPU-Z Test Build] New Kernel Driver, Everyone: Please Test

[bobbybluz]

Tested on my 24/7 daily driver: Asus X79 Sabertooth, E5 1680 V2 @ 4.5GHz, 64GB Corsair Dominator Platinum DDR3 2133, EVGA GTX 1080 Ti FTW3 w/ iCX cooler, Win 10 Iot Enterprise LTSC 2021. Works perfectly on this older rig.

Tested on a laptop, 8845hs, 780m, and Nvidia 4070 laptop.
It seems to load a-bit slower but it loads.

HD 2900 XT 1GB GDDR4, WinXP SP3 (32-bit), Core 2 Extreme X6800 :

^No memory capacity detected, wrong Core clocks, wrong memory clocks, Resizable bar enabled (I like that last one most )

That was extremely helpful, problem found. Preparing new build

 

[Wumyg]

Windows Server 2022 21H2, 64-bit, 4790k, 980ti

Everything but the BIOS info seems to be identical

Everything but the BIOS info seems to be identical

Can confirm the same issue with Windows XP SP3 32bit, 8800GTX 512MB with driver version 175.19

 

[GreiverBlade]

everything's fine on my side
same same as with previous version


Win 11 64bit
R7 5800X3D with RX 7900 XTX


as for oldie
Win XP 32bit
Athlon MP1600 with Xpertvision Radeon X1950 GT Super AGP/Radeon 9700/Radeon 9800 Pro and GeForce 2 GTS/GeForce 2 MX 400

Testbuild 2.66.2 works perfectly fine and identical to 2.66.0 on:

Win11 24H2 64bit, R7 9800X3D @ ASUS B650E, RTX 3090
Win11 24H2 64bit, R7 5800X3D @ ASRock X570, GTX 1060
Server Insider build 26433 64bit, R5 5600G @ ASRock B450, Arc 310 LP (iGPU disabled)
Win11 24H2 64-bit, R3 3200G @ Shuttle A320, Vega 8 iGPU

Testbuild 2.66.2 shows different behaviour than 2.66.0, or both show the same error:

Win11 24H2 64-bit, i5 4590 @ Gigabyte B85, GTX 970 => Bios Info Error + "UEFI Checkbox" missing
Win11 24H2 64-bit, Xeon W3680 @ ASUS X58, Quadro K2200 => Bios Info Error + "CSM disabled = Yes"+ "UEFI Checkbox" missing
Win11 24H2, Win8.1, Win7 64-bit, Xeon X3470 @ Intel 3420, GTX 745 => Bios Info Error + "UEFI Checkbox" missing
Win10 22H2, Win8.1, Win7, WinVista, WinXP 64-bit, Xeon E3110 @ ASUS P45, GTX 660 => Bios Info Error + "CSM disabled = Yes" + "UEFI Checkbox" missing (*)
Win11 Insider build 27881, i3 10110U @ Dell CML-U, Intel UHD iGPU => No VRAM, No GPU Temp

Explanation:

Bios Info Error: the already reported error
"UEFI Checkbox" missing: self-explenatory, the UEFI checkbox is missing, see attached screenshots
No VRAM, No GPU Temp: no memory bus width and memory clock, and no GPU temp in sensors panel, see attached screenshots
"CSM disabled = Yes": this should read "No" on legacy BIOS systems, as the information boils down to "are we running UEFI or BIOS code?", and CSM=disabled means UEFI=enabled (*)

(*)
The GTX 745 shows a corner case caused by the Intel Server Mainboard. It apparently features EFI, but not UEFI support, which HWiNFO incorrectly reads as UEFI-enabled. I think it's because of that very circumstance that GPU-Z correctly reports "CSM disabled = No".
The Quadro K2200 sits on a consumer ASUS X58 board, where HWiNFO correctly detects UEFI=disabled, and GPU-Z incorrectly detects "CSM disabled = Yes"

Windows 11 24H2, 32GB, 5900x, 9070XT. Working well.

@W1zzard Thanks for continuing to update and keep this utility secure!

 

[rethcirE]

Win 11 Pro 22H2 22621.4317
12900K
MSi 4070 OC

Working well here

Win7 Ultimate 64-bit, FX8300 and HD7970

UEFI support and VRAM vendor undetected, wrong memory bus width and thus bandwidth:



ASIC quality missing from the drop-down menu of the Advanced tab:

Hi W1zz, there are no issues on any pane or window in GPU-Z on my primary system, 13900KS, Z790 Apex Encore, RTX 5090 Palit GameRock, W10 22H2. Everything reads correctly and the sensors are working OK. I noticed it loads a lot faster, though, so that's nice. Hopefully I get the chance to try on another setup soon.

 

[Dr. Dro]

Looks to be mostly fine on Windows XP/mid-2010 Mac mini. The only thing that it does is report Resizable BAR as being enabled, but 2.66.0 does the same. It's unable to read the BIOS data, but this is also the same on 2.66.0.

 

[Onasi]

Is it the GPU perhaps doesn't support rebar?

It indeed does not, it’s a Turing-based Quadro. Re-bar is Ampere (via a GPU BIOS update) and later. Both your motherboard and GPU work correctly, the feature just isn’t supported.

 

[W1zzard]

Build in first post updated with 2.66.3, which should fix the issues on older hardware.

Please reboot before testing and don't start the old GPU-Z test build (or it will reuse its older kernel driver)

@agent_x007, @Wumyg, @3x0, @SonicAndSmoke, @QuietBob please test

 

[Sabotaged_Enigma]

It works perfectly.
win10 21H2 LTSC, RX 9060 XT / 6600 XT, Ryzen 7 5700X, B550

still, couldn't show OC frequency of RDNA 4

 

[DarkDreams]

W10 22H2, 64-bit, i5 9400F, GTX 1660 Super
All working flawlessly

NVIDIA BIOS from Advanced Tab still missing info. FYI, main page at least shows correct BIOS version on both test builds.

Ah I forgot, please reboot before testing and don't start the old GPU-Z test build (or it will reuse its kernel driver)

or in a command prompt
sc stop gpu-z-v3 and sc delete gpu-z-v3, to ensure the driver is really uninstalled before starting

 

[Stemmi]

2.66.3
W11 24H2, 64-bit, laptop, i9-13950HX, NVIDIA RTX 3500 Ada
First startup was so slow that I had to check if process was even running.

While comparing to 2.64 I noticed calculation or data source error on monitor link rate values.

Is this event viewer entry from the new build? this just appeared when I tried the new one..

yeah thats log output, change the view mode and you can see the text

Tried it after removing the driver and rebooting, still the same

i9 10850k, MSI Z490 MB, 32GB DDR4 3200 RAM, RTX 4080 FE, Win 11 Pro 64bit. Works as it should

@W1zzard: I have those errors in the event viewer too. Version 2.66.3.
