Currently attempting to find the best GPU for my system, an Aiwa PC MT-601 - motherboard pic here : https://i.imgur.com/yIsyOr9.jpg
I've tried a range of cards to limited success, these are:
Riva 128 4mb - works but card is failing, crashes a lot.
Matrox Millennium II 4mb+4mb expansion - works
GeForce 2 MX200 32mb - Black screen but pc activity suggests it's at least somewhat booting
Radeon R7000 64mb - Black screen same as GF2MX
Radeon 9200 128mb - Black screen same as GF2MX
Now, this is a pre-AGP 586 system with a Pentium i200 processor, so I can completely understand the R7000 and 9200 not working, but the GeForce 2 MX200 I would have thought would work?, I don't actually know what PCI revision the board is using but it seems keyed for 5V 32bit, I've probed around and the pins on the PCI that are marked as "3.3v/5v" measure as if they should be 5v, but any pin marked as 5v or 3.3/5v, are reading as 4.83v but testing on another motherboard that the cards do work on, I'm measuring 5.07v on the same pins, I don't know if that 0.17v from 5v (or 0.25v difference to the other board) is a large enough drop to make it only work with some cards, I'd imagine if the voltage was too low none of the cards would work?
Is there something I'm missing here?, is there a PCI revision difference between the Matrox millennium II and the GeForce 2 MX200?
