@Loeschzwerg
AFAIK there are documented strapping configurations up to 16Mb chips for VSA100 but there are some combinations unassigned so if you have the chips you could try them. Stacking on the other hand should work in theory, but soldering would be a nightmare; I admit I don't believe I could solder piggybacked TSOP86 chips but if anyone can, it would be you.

Was there ever an instance when I did not share the informations on how to replicate the mods I've discovered?
Was trying to borrow a camera better than that on my phone, yet no luck here, so if one could help by uploading hi-res pics of the front and back of a V5 pci I'll do my part. No BIOS hack is required and the mod is fairly similar to that of a V5 agp.

I wonder what to do next; I like the challenge of venturing into unknown but, though I have some ideas, I have not chosen a new mod to tackle, so I'm opened to suggestions...


As long as you could provide diagrams and resistor values images are not strictly necessary although still useful (they can be added in any time) Wink

So would be nice summarize your whole work, V4 and V5 projects too, in order to preserve informations.

I just had this idea, but it depends on something.  I know Voodoo 's can be used in SLI, but can Voodoo 4's or 5's?  If yes, then what about a 128mb or even a suggested 256mb Voodoo 5500 in SLI?

Now my other idea was, could two cards be made into one?  Hear me out. 
This might need the  mentioned PCI-X slot but anyways, if they could be used in SLI, could they me hardwired together, or soldered at the pins instead of using a cable, then via some sort of dongle, maybe even pcisagp or if possible pci2pci-E, be made to use one slot?  I know it sounds odd, but hey, if I am wrong I am wrong but it's just an idea.  2 cards working together.  Would be neat, especially if you could extend the SLI to be able to link more than 2 cards, say 4 in SLI?  I mean, how did they do the  mercury brink right?  It worked somehow.

@Komponent: Thx Smiley

@bucksavage: You might find the following thread interesting: http://www.falconfly.de/cgi-bin/yabb2/YaBB.pl?num=1355402726/0

A hardware SLI setup is clearly the better solution, cause it doesn't stress the primary PCI bus, like a software solution will/would do. The problem, we would need to build a secondary PCI bus like used on Voodoo 5 6000 or the AAlchemy and this simply isn't possible, at least not without some very difficult and heavy modifications Sad (rebuild a 6000 would be easier if you ask me)

So I would go for the software SLI solution, but my skills in driver development are rather bad to none existent...

@Komponent: Ok.  Was just a random thought I had. 

I wonder though.....has anyone tried to make a brick module out of more modern voodoo cards, say V4k or V5k?  And how exactly would you hook it into a pc?

@Komponent,
Excellent work mate!

About V5 @256Mb:
Same work as Komponent showed plus strapping ball A24 of both VSA-100  to enable second chiptset. Bios must recognize the card with double ram once added 32Mb per TSOP.

Regards,
Oscar.

Not sure about that, I think that A24 will only be needed if piggyback two 16MB. Cause this would result in two chipsets, using 32MB is only one.

A V4-4500 agp only with A24 modification went 32 @64MB once soldered 8 tsops.

You are right and I will tell you why, the VSA100 on the V4 AGP does have wired CS0 and CS1 to all memory spots. To make use of the 4 free tsops you need A24 to activate "chip select".

But the V5 does only have 4 tsops per VSA100 and not 8, so it addresses only one memory chipset per VSA100.
If we go for memory with 32MB per chip we don't need A24, because we don't need to select between two memory chipsets.

If we are forced to go for the piggyback method, we need to wire CS0/CS1 (they aren't connected to both VSA100) and A24.

Ok, understood.

So, V4 128Mb mod is done via A24? I did not know it. I checked the Komponent's V4 mod and there was not nothing about A24 strapping but now I remember in such mod there was a file  bios mod. Possibly there is enabled second chipset.

Oscar.

Thanks Komponent.

If we go for 32Mb per chip. We must play via strapping with:

MD10/11/12/13/14 & AAD11/10/9/8/7

Trying to find the right set?

Oscar.
