1.5v video card?

[homestarmy]

Hey, I have a K7VME board in my cube PC and it says it will only support 1.5v video cards. How do I know the voltage of a video card? How can I know if my existing Radeon 9000 is 1.5v or not? What other voltages are there etc?

Thanks in advance!

As a general rule of thumb:

2X AGP = 3.3v
4X AGP = 1.5v
8X AGP = 0.8v

But I think there were a few cards (maybe 3DFX Voodoo 4 or 5) that did not conform. Someone a little more knowledgeable could help there.

9000 should be 2x and 4x compatible

So do you think that means that the board will ONLY support 4x? Or will it support 2x and 4x or...? Thanks!

8x AGP uses 1.5V signalling too - only the voltage _swing_ (the delta between a valid High and a valid Low) has been lowered to 0.8V. This is _not_ "0.8V signalling".

Radeon 9000 does 3.3V and 1.5V signalling (2x, 4x modes); the 9200 adds 8x support.

So it's the signaling that's important?

Your Radeon 9000 should run fine in any system as long as its AGP 2x, 4x, or 8x

I have this same mobo, and it smoked my 8500DV. I thought I had a bad AGP slot, but that's not the case? Just call me stupid.
