hi guys,

I have a Intergraph Intense 3D rev.D .....Voodoo Rush based card.
It has a special silk screen "SH" on the 3dfx chip

What can it mean?  :-?

Furthermore, this card does not work well in 3D; color images look altered on glide and direct3d mode

normal is it not

9732 is not an early one. maybe it was the preowner

not the previous and single owner has not written anything on the card.

I add... it is not hand-written and not written with simple blank trasfer, also you can not erase it with rubber.

I have similar markings on another Intergraph card namely the Intense3D100 see here:

As to what they mean I'm not sure but it could be some internal classification of chips and pcbs (they also have stamp marks) that were added after QA testing.
Cheers,

yes is possible G1nx!

in 2d mode no problem.

Artifacts, bad memory.
