Re: 3dfx Voodoo5 glitches
I did find something with Q1-Q4 (IR IRF7811A = MOSFET N-CH 28V 11.4A 8-SOIC)
Bad card Q1-Q4 to gnd
Q1 0.5v 1 side 3.0v other side
Q2 1.75v to 3.0v
Q3 3.5v to 3.0v
Q4 12v to 3.0v
Good card Q1-Q4 to gnd
Q1 0.5v to 2.8v
Q2 1.9v to 2.8v
Q3 3.5 to 2.8v
Q4 12v to 2.8v
No idea if that tells anything, what do you think? I've very little experience with this stuff. Learned a lot from the guy at vogons.
I would like to try your option, can you tell me how I would accomplish it?
I hope not, but the card works fine without guardband clipping, checked in 3Dmark2000 against the good card with single chip and dual chip performance. Single chip and dual chip had the same scores with both cards (double with dual chip mode that is).

It is possible that you could have a bad gpu BGA issue. I think the front chip runs all the time and the rear chip only kicks in during 3D detection rendering.
