Hi there, first time posting in the site, I think you might be able to help me

I have this motherboard lying aorund and I was planning to put it in use very soon, specifically because of its seemingly universal AGP slot.

The thing is, I bought a bunch of old video cards that I really want to test, one of them being a Creative Banshee which needs 3.3v AGP, so I thought it was perfect for the job.
I dont have a "legit" 3.3v notched AGP Slot motherboard to use at the moment, and my other motherboards are 1.5v notched.

I know this is a delicate matter so I did a bit of research in the Gigabyte website: https://www.gigabyte.com/Motherboard/GA-7VM266-rev-10#ov
The manual specifies very clearly "1 universal AGP slot (1X/2X/4X) device support", which leads me to believe it should take a 3.3v card
On the other hand, the "Specification" section in the Gigabyte website states "AGP slot (4X/2X, Support 1.5V display card only)"

So... what is the truth?
1) Is there a way to confirm this more than risking a video card? (it would be a cheaper 3.3v one)
2) If I do that, is there any risk for the Motherboard? that would be a no-go

My hope is that someone here owns this same motherboard and has already tried 3.3v cards on it, if that's the case please let me know

Thanks in advance
