HWiNFO v7.01-4410 Beta released

[Martin]

HWiNFO v7.01-4410 Beta available.

Changes:

• Enhanced sensor monitoring on ASRock Z590 OC Formula and Z590 Phantom Gaming-ITX.
• Fixed unintentional waking up of some NVIDIA dGPUs disabled by Optimus technology.
• Added reporting of PCI Express Resizable BAR capability and status for all devices.
• Enhanced sensor monitoring on MSI Z590 PLUS, MEG Z590 UNIFY and B560M PRO WIFI.

A note regarding the new Resizable BAR information.
This is available for all PCI Express devices (not only GPUs) in the main window - Bus under each device node:

This feature supports individual settings for multiple BARs (Base Address Registers). For AMD BAR0, for NVIDIA BAR1 is of most interest as for GPUs this is the framebuffer memory space that will see a performance improvement when this feature is enabled and properly handled.
The first item (Supported Size) specifies the device capability and is independent from BIOS or drivers. Each device can support different sizes.
The second item (Current Size) specifies the actual setting. This depends on whether the BIOS is supporting this feature and enables it.
On the above GPU example, the 8 GB (maximum) current size means this feature is enabled as it extends the BAR size from legacy 256 MB to 8 GB. When the BIOS doesn't support or enable this feature, the current size would be 256 MB.

This information is also shown for each GPU with a simplified format (BAR0 only):

This shows whether the capability is supported by device and actual state set by BIOS (>256MB is treated as supported).

Hi Martin. My apologies for resurrecting something so ancient. I am very late to the party, and am only just investigating this now.
I know how to verify whether Resizable BAR is supported and enabled, although I'm still in the process of understanding how to verify actual functionality. Until then however; I am very curious about this feature lookup. While GPU ReBAR support is clear; what isn't clear is Motherboard and CPU support. Now for both my desktop and laptop; I get this "Resizable BAR Support: Not Supported" for the PCI Express Graphics/Root Port. I understand that you cannot divulge how you do this lookup, but is there any chance you would be willing to suggest how one could try to understand why these are saying "Not Supported?"
Both my PCs are apparently fully ReBAR compliant, but I have doubts.
Would appreciate any feedback, even if it's to go take a hike.
Thank you.

EDIT: HWiNFO Version In Use:

Spoiler: Desktop PCI-Express Controller

Spoiler: Laptop PCI-Express Controller

Spoiler: Desktop GPU-Z

Spoiler: Laptop GPU-Z

EDIT: Interestingly the PCI-to-PCI bridge devices do show that they use Large Memory in Windows device manager. #Freaky.

Spoiler: Desktop DevMgr vs HWiNFO

v7.01-4410 Beta (Mar 16, 2021) and RTX 4060 announced at 2023 ??? Try update to v8.17-5625 Beta or never. Any diagnostic program has the right not to be able to work with equipment created much later than the moment of its creation.

Nice one. Added/updated screenshots for you. Fortunately/unfortunately I'm crazy but not that crazy.

You need to check ReBAR support for the respective GPU device not the PCI Express Port.

Everything is simpler - I am an engineer, and therefore I look at things differently - whether the program earlier in time can read the program correctly and interpret the state of the state of more new time development and is it possible when its state codes changed its meaning and the program deciphered them incorrectly?
