Long time lurker, first time poster.
Please could someone let me know if this card will work on 1.5v? I can't tell if it's co-incidence or a sorry tale that the motherboard I tried this in no longer powers up.
IBM FRU:10K2111. On the card is written: PCB#01-868602-00 REV 00 M64 4Mx16/2Mx32 SDRAM AGP DVI-I

Screw period correct; I wanted a faster system back then. I choose no dropped frames, super fast loading, fully compatible and quiet operation.

The agp connector has 2 slots which means it should support both 1.5V and 3.3V signaling voltages.

In theory. in practice, not so much. I have 2 M64 cards, one works on both one is fixed to 3.3V (guess how I found out). Both have "universal" notches. Unfortunately up to the Geforce 2 generation you can't tell by looking at the connector if the voltages are supported accordingly.

BTW, the inverse is also true, There are motherboards that have universal slot but only support 1 voltage, usually 1.5V.
