While I was scout'n around I came acros this:
http://www.3dfxzone.it/enboard/topic.asp?TOPIC_ID=248&whichpage=1

heh Hank maybe you remember it hehe, here the things you wanted to try out:

1) V5 AGP 4X slot support
2) V5 more memory
3) 2x V5 SLI
4) 2x V5 6000 SLI

Okay a few pages on I read this:

Originally posted by hanksemenec Hi Guys, VSA 100 is capable of supporting 1.5V signalling required for AGP4X slot. The IO voltage ring on the chip is isolated from 3.3V supply. There is voltage refference on V5 that will support 1.5V, but it is disabled through a pin called Sense. The mechanical problem of plugging V5 into AGP4x/8x slot can be gotten arround by using a riser. The MB will not burn since the IO voltage is isolated (AGP VDDQ Plane). You will be limmited to PCI 66 speed, there will not be DMA! You can afford to send more virtex info and do texture paging upto the bandwidth limit of pci 66. Hail to the king.....Baby (I think this one is better from Ash :-P)

that was made on page 4

So there by AGP x4 and x8 should be possible for VSA-100 well AGP x4 is anyways if we look at 3dfx's Voodoo4 4500 AGP card, but was there a way to enable 1.5 Volt supposrt by removing that pin called Sense?

Or was the whole AGP x4 not possible because of the SLI bridge?
Oh well @ least the extra Ram idea is theoreticly possible:

I know that 100%, I pinned out Daytona. To make Daytona run fast you have to adjust DQS line, my black magic. I have a programmable delay line on PCB for that. About a year ago I have posted rework for V5 5500 to expand the ram, looks like I'll have to find it again. The same can be done to 6k, but the ammount of solderring, sheesh :-P. Hank

that was made on page 10

but dunno about the SLI idea for both cards 5500 and 6000 not missing 4500 and 5000 heh. You'l need to remap the whole cards for that I guess.

but on the other hand then the SLI idea would be possible since Alienware did it with 2 Voodoo3 2000 PCI's with Metabyte's Wicked3D Parallel Graphics Configuration aka PGC, so if we could get that working with like 6 Voodoo5 5500 PCI's instead we would have the speed of 3 Voodoo5 6000's instead.

here is what BFG3dfx said back then:

Originally posted by BFG3dfx wow you posting mad man lol, ok in my post i stated the v3's ALIENWARE had running together lol, let the post begin. Quietly tucked away inside the massive Eidos booth were three Alienware Area 51 high-end machines. While they didn't get as much attention as the games they were running (ION Storm's much-hyped Daikatana seemed to be attracting a crowd), each of these machines was being powered by dual Voodoo3 2000s, made possible by Wicked3D's Parallel Graphics Configuration (PGC) technology. Prior to the showing, naysayers were quick to list possible flaws that included visual artifacts, images that weren't synced properly, or even a dividing line cutting across the monitor. That wasn't the case here - in fact, all three machines were running flawlessly, and although there was no benchmarking utility on hand, using the ol eye-balling technique, the manufacturer's claim of a frame rate between 50 and 60fps wouldn't be too far from the truth. And while a single 143MHz-clocked Voodoo3 2000 doesn't stand a chance against the likes of a TNT2, a pair does - especially considering how easily each overclocks to 166MHz. In fact, Alienware (currently the exclusive proprietors of PGC-enhanced video cards) has claimed to attain frame rates above and beyond 70fps while running Quake II at a blinding 1600x1200 resolution.

and indeed there was more with the same SLiéd V3 2K PCI idea:)

Originally posted by BFG3dfx another, Alienware Delivers the World's First Wicked3D PGC-Enabled Gaming System On May 7, 1999, Wicked3D, a division of Megabyte, Inc., announced that Alienware was going to be the first company to license its Parallel Graphics Configuration (PGC) Technology. This allowed two 3dfx Interactive Voodoo3 2000 PCI cards to be combined in one system and delivered 55 frames per second without overclocking. so anyways the reason i brought up the v3's BloodWorm was because they didnt use a speacial mobo unlike thses pci-e boards now. also i thought maybe someone had some insight since they were 3dfx cards and they asked 3dfx to help out at first. somewhere was the article on them doing the hardwasre mod to the cards, ill look for that one.

those 2 posts were made on page 18 ;)

So with this info still in mind why didn't this idea get any further? Was it too complicated, were there things missing like the needed software to make this idea work?

Anyways I thought it was interesting to get this idea back to life because I have a feeling that there is hope that this might work one day.

I would love to hear what you people think, but one thing is certain this is all very well possible in theorie ;)
