AGP 8X Volatage Question

[crazyhandpuppet]

I have an MSI FX5600-VTDR VC in a DFI LanParty NForce2 Ultra 400 (Something like that). Anyway, recently I've been reading and I guess AGP 8x runs at .8V and agp 4x runs at 1.5V. When I look at the Voltage for my AGP in speedfan, it also shows 1.5V. Shouldn't the card be running at .8V? It is an AGP 8x Card. I know 8x is compatible with 4x and so 1.5V isn't damaging the card (been running like this for a couple of years now) but shouldn't the card be at .8V? Wouldn't it run cooler at .8V than 1.5V like a CPU at a lower Voltage?

AGP 8x runs at 1.5volts minimum. And btw it's the slot bandwidth. This does not affect the voltage of the GPU's...

at least, that is what I know... but I'm far from an expert.
