Sugestions for VooDoo based projects

Hi all. Hank, that v5 rework instructions would be great. I have one humble request for you. Is it possible to do a voltage mod on a v5 pci? I have sufficient cooling, would like to try. I know someone posted a voltage mod for v5 agp, but pics were crapy, and wouldn't tell a thing. I need the v5 maker's help.

Same here

I have a PCI V5 so AGP does not interest me so I would say more RAM and SLI.

[osckhar]

We need to get a mod for the v5k and v6k, or in 2 year more  our cards will be totally obsolete!

We need more RAM (128mb), And support agp4x!

But is possible to get memory for to work for above 200mhz (memory 5ns)? the v5k could  be compatible with it? And if is yes, who will be  the magic man capable to solder the memory? I thing that manually is not possible, no?

Hank could to do this mod?
He is the king, the god of the 3dfx cards. If he can't to do this, the voodoo will say to us good bye.
Is my modest opinion!


Thanks
Regards

AGP 4x support does not bring any increase in performance, the difference between 2x and 4x is pretty slow, and the voodoos dont support AGP texturing anyway.
Overclocking the VSA-100 gives you an increase in fillrate, but the overall performance goes not gain much.
A member of the german voodooalert forum did some tests with a V5-6000 on a modern system, but the results of the overclocked V5-6000 showed almost no difference. If you are interested I can search for the diagramms...

I think that the most important, is not the performance under agp4x or else can to place (v5k or v6k) in the modern motherboard!;)

Overclocking the VSA-100 gives you an increase in fillrate, but the overall performance goes not gain much.

I have seen that, when I am trying overclocking, the performance is better when I work to 166mhz (v6k), If I try to up the mhz, the performance down (3dmark2001)!
For me the best overclock is across the FSB, then the performance is a lot better!

Yeeeeees, I want to see it!

Thanks Rolo01!

Yes Osckhar, you are right, it would be great if we could use our voodoos in every modern motherboard.

Anyway, here is a graphic of that V5-6000 overclocking :


Image Insert:

28.28 KB

The system was : Athlon 2400+, 8K5A3+, Voodoo5 6000, Audigy2, 1GB DDR
I am not sure, but I guess the benchmark was Quake3 timedemo 1.
The headline means : effectiveness when overclocking

Another graph about scaling :

DAMN, Why the performance is the same, working to 166 that to 195mhz?
Then, is useless to do overcloking, no? I think is better to do overcklocking across of the fsb... The performance is more high!

Thanks Rolo01,  diagram very interesting!!!

back to the topic

Is it possible to activate/to build  by a AGP4x/8x motherboards a AGP 2x slot and also use it like AGP2x ? So it will be possible for all of us to use voodoo's( inks Banshee  etc.) in newer motherboards. I know,it isn't just a slotplastic change , but maybe it is easier to make a Voodoo5 5500 AGP an AGP 4x card..

[bloodworm]

sloomy,
the Intel specification on the AGP 3.0 "universal" slot calls out that it CAN be capable of distiguishing between the different cards that may be placed in it and setting the AGP voltage/speed accordingly.  The motherboard manufacturer must choose this when designing the board.  I am afraid that there is no converting a 4x/8x only motherboard to accept these different voltages after the fact.

hi my first post on this site so dont grill me plz
i have read the thread so far and was just wondering is it possible to fabricate or if it is a standard part to attach a agp controller to the voodoo 5 bcause from what i saw early on in the thread it said that the reason voodoo 5's only worked at pci66 was the fact that there was no agp controller on the card because 3dfx never put one on.
..(if that is irrelevant ignore it)

as for the extra ram i too would be interested in getting together with whoever else wants to and putting in money to buy a batch of the correct type ram if no small quantities could be found

voodoo 5 sli would be very fun if it is possible but i shall leave it upto hank to find if it is

and lastly i have always been curious but could never find out what it was for....what is the connector on the top edge of the voodoo 5 actually for? its labelled p3 but that doesnt really tell you much about it..oh well...

i appreciate any and all feedback..

Voodoo 3 2000
2x Voodoo 2 (12 mb)
Voodoo 5 5500 (agp)

no, this is because in order to create accellerated transfer (i.e. 2x/4x/8x), one chip must be assigned as the master chip, which cannot be done with dual VSA-100s. I wonder how QDI worked around this...

awesome

Some have said that it is, but I have my doubts...

It's a feature connector, for adding something like a TV tuner, I believe.

[Nightbird]

This is a digital video in connector for connecting video capture, tv tuners, dvd decoders... cards
The problem : is this connector standard ?

DAMN, Why the performance is the same, working to 166 that to 195mhz?

I know this sounds pretty silly, but I honestly think the v5 6k hasn't reached it's max fillrate yet, thus why there is no difference with the higher mhz.  
I experienced the same when I used to have my v5 with an athlon 750.

Onto the main topic here, I have the v5 reworked image Hank was talking about. I downloaded the picture a while back when Hank posted it on the X3dfX forum. Gimme a lil bit of time and I'll try find it and post it.  

[bloodworm]

Hank,
    I have the .jpg's of the address line reworks, but I don't have the memory "jumper" resistor changes.

[Dan]

as far as I have seen the "accessory" connector is standard to all 5500 cards, but then the problem is still has anyone figured out the pinout of the port, if so, the DVI connection area on the PCI 5500 might be used to loop video into a second 5500 for an SLI setup.
