Hi everyone. I have a bit challenging thing.
We need to identify this videocard. This is the maximum resolution that we have.

Screenshot010166.png

What we have:
- SiS
- Dual VGA
- AGP 2x
- Maybe a SiS 301 additional chip?

It could be an exibition item or a kind of one-off prototype. Any idea?
My ideas are Sis 300, 305, 336 or any other prototype numbers

Dual-VGA? It looks like VGA + TV-out

That memory arrangement suggests to me 128-bit bus. Along with the old AGP connector I would dare to guess it is a SiS300. Can you acquire her?

Memory chips are located as on Xabre board:

https://www.vgamuseum.info/images/zaatharen/s … bre400_fhq2.jpg

but on Xabre, there is no "SIS" marking on the chip. So, my best guess is that it's "Sis 315" with less (or higher density) memory chips:

and "Sis301" chip soldered as well:

[EDIT] but it really looks so much like Xabre, apart from the "SIS" marking on the main chip:

Yes - It has Dual VGA plus TV-Out

And it has an AGP 2x which is insane for Xabre as well as for 128-bit memory

Unfortunately not.
This is a photo from ixbt magazine. Their editor's room got looot of prototypes. Such as Sapphere 9800 Pro MAXX or Kyro 4800.

SO for me this SiS looks very special with all these mismatched features.

SiS 6215 or 6326. There are numerous different types of PCB's using the 6215 and 6326, with no set standard. It's showing an MPEG-2 decoder chip as well, so I'm leaning more toward the 6326.

Agree, Sis300 seems to me physically smaller. Now I think it is some 6326.

It wouldn't be a 30x, as they were AGP 2x/4x. 6326 only came in AGP 2x.

Yes - It has Dual VGA plus TV-Out

Hmmm… i can see only one VGA. Maybe there some kind of splitter?

Probably SIS 3xx prototype. Hence why larger chip (bigger fabrication process) and AGP 2x.

i can see only one VGA

Second VGA is connected through ribbon cable.

Thank you. The problem with "6326" is that on the picture we have something like
3 digits below SiS logo on a chip.

For me it can't be "6326" because this text will be longer:

Also it has a BGA chip like SiS 300
not a 63xx series.

So I am definitely goes with SiS 3xx

I agree. Large BGA chip made with large fab process.
More chances it is SiS 300 or 305 prototype made between 1999 and 2000.

As I stated, the 3xx is an AGP 2x/4x card. Yours does not have the 4x pin layout. The picture is so blurred out that we'll never make out what it is.

Many 305 cards have a jumper for AGP configuration. Maybe a prototype could have been on a AGP 1.0 card.

...when you zoom the original picture, there is a slightly different shadow under the AGP connector - so it is possibly AGP4x. None of 6326 (or earlier chip) has not 301 chip and also was not dual VGA.
It must be SiS 300.
SiS 305 was not dual VGA and later cards was with DVI...
