GPU-z shows wrong graphics card

[Coogar]

Hello to all and each of you,

I do not have a problem (well, I do have a small situation, but that is not why I post).

How does GPU-z work? Where does it retrieve the data from?

GPU-z (ver 0.5.4, the latest) is showing the wrong videocard. No, it is most likely not GPU-z's fault.

I wanted to replace a 64-bit Radeon HD 3650 with a 128-bit Radeon HD 3650 from Sapphire in an old AGP-based computer that I have (the PC doesn't boot, by the way: lots of beeps and a black screen - but nevermind that).

In another computer, the Sapphire works fine (so, the card is not defective - could it be a PSU issue?), and there GPU-z says it is a VisionTek Radeon HD 2600XT. So does Windows (XP Home) Device manager.

SIW ("System Information for Windows") too says that it's a VisionTek Radeon HD 2600XT.
However, a little lower at "PCI ID" SIW says that that it's a "RV635 Pro AGP / [Radeon HD 3650].
The PCI Sub ID, then, shows "Hightech Information System Ltd" (aka HIS).

The card definitely is (looks like) a Radeon HD 3650 from Sapphire. So, why the different information? Sapphire? VisionTek? HIS?

Consider this as a technical question. I like to know a lot about my computers, so I like GPU-z very much

Here is a picture of the 64-bit Radeon and of the Sapphire:

It definitely is a Sapphire.

Here is the "SIW" screen:

Peculiar, isn't it?

Such problems happen to AGP cards. For example HIS 4670 didn't even want to "take" the latest drivers, it only works fine with 10.7 version.

(the PC doesn't boot, by the way: lots of beeps and a black screen - but nevermind that). In another computer, the Sapphire works fine (so, the card is not defective - could it be a PSU issue?)

maybe the problem lies in mobo.
