New world's first: Voodoo4 PCI 64Mb -little dragon
10.10.08 at 00:29:54
 
Another mod has been completed: standard 8Mb chips were replaced with 16Mb modules on a Voodoo4 PCI with the extra memory adresses hardwired. After that, strapping configuration for the memory initialisation was modded on the PCB (and finding the right setup was harder than expected). No BIOS mod was required. The card works with no problems in Windows 9x and 2000/XP/2003. Have a look at some pics:

...

...

When the computer starts, it displays 64Mb video RAM:

...

Ofcourse, it was time to test the modded 64Mb card against the regular 32Mb Voodoo4 PCI.

3DMark 2001SE Voodoo4 32Mb No AA: 1563 points

...

3DMark 2001SE Voodoo4 64Mb No AA: 1686 points

...

3DMark 2001SE Voodoo4 32Mb 2x AA: 690 points

...

3DMark 2001SE Voodoo4 64Mb 2x AA: 867 points

...

To summarise: we have 123 3DMarks in No AA mode and 177 3DMarks in 2x AA mode counting as the performance gain by adding 32Mb video memory.
As always, I will soon provide detailed instructions about how to replicate yourself this mod.
My thanks go to G1nX/RaverX for offering me the chance to work on theyr card and especialy to Rolo01 for the over the years help and support.

Thank you Komponent for making all these premiers possible. It's great that the V4 PCI works without issues on win98/2k/XP. Hope that the driver issues with the v5 agp will be solved with a new driver pack so that we can really appreciate the dual gpu + extra memory.
Great work thank you once again.

Not so much enthusiasm about this mod, I see... Oh well... anyway, I want to provide the details about the steps to be taken to do it yourself, but I failed to borrow a digital camera, so if one of you could please provide a high-res picture of the back of a Voodoo4 PCI it would be of great help. Thanks.

Fairly cool stuff, good job indeed Smiley

Now if there was only a way to avoid those wires (basically make it look more sleek)... I'm thinking of a custom Cooler with a 3dfx Logo that just sits over all the hard-modded wires and such, for example Wink

Thanks alot, Rottentrearts! In the picture bellow I have marked the mods to be performed on the Voodoo4 PCI to have a fully functional 64Mb device:

The little Dragon all grown up:
...

And some comparison tests:
System used Tyan S2466MPX with 2xMP2800+ and 2Gb ECC Reg.

V4 32Mb @166Mhz NoAA PCI33
...
V4 32Mb @166 NoAA PCI66
...

V4 64Mb @166 NoAA PCI66
...

And a little OC with no artifacts present and perfectly stable:
V4 64Mb @183 NoAA PCI66
...

When using the PCI-X slot the performance in near to that of a v4 agp.

Thank you Komponent for making this possible.

As always, congrats on another great mod Komponent!  (of course this latest edition probably means a bit more to me than anyone else)  It really is great to see these cards being modded by you.  It is just crazy to think what the reaction would have been back in the day if this was being done.  Hell, its 2009 and I am still shocked  Shocked

Keep up the great work!  Wink

Wow!

And how ?

Nice work, I'm sure if I tried that it would be an epic fail.

My friend Gino sent me a V4-4500 pci MAC version. Idea is adding extra mem, tv-out and upgrade vsa-100 chip.

Here the nice card.

...

All was great but I had a lot of troubles with TV-OUT. Once I added all the components. I used a V3 3000 as donant . I found problems since I would need an original V4 proto TV/DVI out to unsolder / re-solder smd components and check values for Resistor, Condenstor and Inductors.

With all the smd components installed card does not want boots up. Card was detected via PCI.EXE but not sign in the monitor. When I tried update bios, program detected it as UKNOWN 3Dfx board. Once I removed all the smd compoents card booted up ok. At the moment project is stoped, but card works smoothly with extra memory but NOT TV-OUT funtion though.

...

...

Regards,
Oscar.

must be very expensive to ask you for modding a card like that.

For example, making a V5500AGP a 128mb instead of 64mb.

But then again, it must be worth it more if you have a MAC edition flash to PCI so you get the much better DVI connector.
