Help! Question about agp 3.3 volt and 1.5 volt

[thefly]

Okay,

I think i might have screwed up here. I've got an mx440 Se card which appears to look like 3# in the picture at the following website...

So, the card has both 3.3 volt and 1.5 volt keys on the card.

I think i might of screwed up here because I put it into a board that says Do not use a 3.3 volt agp card in it. The board is (was) at asrock p4i65g.

The card fit fine, but the system won't start and I think the agp card might have killed it.

I thought because the card had 1.5 key it would be okay. ??? Can someone confirm that i screwed up big here??

Figure 4. looks like what i just did. I thought i was okay doing this but the board seems to have a burn mark on the underside near agp slot.

okay. after looking at this a bit i don't think i made a mistake. The mx440se should be fine in this motherboard. After looking at the bottom of the board it looks like one of the voltage regulators caused the burn.
