Hi,

Here a V5 MAC versión with ISSI 32Mb per chip TSOP and updated last rev. chip VSA-100.  The TSOP memory has been soldered pin by pin with a soldering iron since I prefer it than using an IR system with solder paste.
It takes me more time but even so I prefer it. Clean work.

Here some pictures.
...
...

@komponent,
A23, A15 and B15. Strapping is 4.7kohm to GND. Does it is same setting than used to 128Mb, right? I mean I must to follow same steps that you used for modding 128Mb and see what happens.

Best regards,
Oscar.

Nice  Smiley
To be honest, I also solder RAM chips by hand.
I would first fully replicate the 128Mb mod, then try only B15 (or next only A15) with 4.7k to GND.

Hello,

I have tried to  modify little bit the mod using the VIAS for connecting the wires  and so not solder the wires directly on the pin chip ram and only using wires on the back of the card.

So, looks the card once done the reworks.

...

...
...

Sadly the card oes not work well. It has some artifacts. Sad

Card is showed with 128Mb bios.
...

...

I thought the card would work ok even soldering the wires on the VIAS but perhaps those vias are interconnected with others points and for such reason card does not work well.

What do you think?

Regards,
Oscar.

Shocked It should really be quick to have it fixed that "oops".
After, if you find the strapping for 256mbit chips the start screen might not show 256Mb, but you will see this in Windows.
The RAM is 6ns (166mhz)? I wonder how will it be  overclocking as you took the effort to replace the GPUs.
Can't wait for you to post more news on how this one goes!

I got the two 128mb moded Vodoo5 cards, the agp and PCI version from Komponent.
Thanks a lot Komponent for the great modding !

So here they are:

Voodoo5 Agp

...

...

Voodoo5 Pci

...

...


The cards were testd in differents sistems, with differents OS.

Used Hardware
Tyan S2640 - tested the agp & Pci versions
Epox 8K5A2 - tested the agp & Pci versions
MSI KT3 - tested the agp & Pci versions
ECS K7VTA3 - tested the agp & Pci versions 
Gigabyte M750SLI-DS4 - tested the Pci versinos under XP and Win7, and i also test my both pci2pcix adapters that i own - same behaviour, just black screen when entering windows


Used OS:
Win 98
- Original 3dfx driver
- Amigamerlin 2.9
- x3dfx_V5_Win9X_1.08.04
- Raziel64 Evolution Driver - Expert Edition V1.01.16 (Lite)

With all drivers & boards: entering in the OS wihout problems, colours & Icons sometimes are not displayed corectly ( white icons ) and under applications the sistem freeze.
( 3dmark2001, return to castle wolfesntein, 3dmark2000, UT GOTY, 3dfx donnut demo )


Win XP
- SFFT Alpha 48
- SFFT 1.5
- SFFT 1.6
- SFFT 1.7
- SFFT 1.8
- SFFT 1.9
- Koolsmokey
- Amigamerlin R3.11

With all drivers and boards: When entering in the OS the screen is black.
- Only with the original XP driver - is entering the OS, but the driver does not allow to start any application.


Win7
- SFFT 1.9 - black screen when entering windows
- Only with the original win7 driver - is entering the OS, but the driver does not allow to start any application.


BUT.... there is a board witch surprises me :

The Gigabyte 7VKML -chipset KT266

...

With this board the both cards are running excelent ! No problems in win98 & XP, with all the above mentioned drivers.
I had only a xp1800+ CPU, so don't be amazed about the low scores Smiley


Here some screenshots, using the SFFT 1.9 driver:

No AA

V5 AGP-64mb

...

V5-AGP - 128mb

...

V5-PCI - 64mb

...

V5-PCI - 128mb

...


2xAA

V5 AGP-64mb

...

V5-AGP - 128mb

...

V5-PCI - 64mb

...

V5-PCI - 128mb

...


4xAA

V5 AGP-64mb

...

V5-AGP - 128mb

...

V5-PCI - 64mb

...

V5-PCI - 128mb

...


Some nice shoots @4xAA :

...

...


Btw - overclocking the cards with the VSA overclocking tool goes up to 188Mhz, after that display errors appear.

Fantastic work, M14Radu! Thank you for taking alot of your time to do these tests and sorry you had the bad luck of having that number of incompatible motherboards. I only tested a few and had the chance that all of them worked just fine with modded cards at least under Win ME and with the two I have now perfect function with XP too. One day we should do a list with the other owners of modded cards.
The only missing thing to make your massive work complete would have been if you had at hand a 64Mb Voodoo5 PCI to benchmark that one too in the same configuration. Funny that the 33Mhz speed is such a bottleneck and it takes 4x FSAA for the Mac Voodoo5 to really show its teeth and overpass the 64Mb Voodoo5  Angry

@komponent,

This afternoon I will start again in the mod. I keep you informed. Yes, memory is 6ns, so I dont expect too much O/C with this memory.

@Radu,

Excellent work. Once I end Gino's card I will test it on my epox boards and I will let you know.

Regards,
Oscar.

@osckhar: The card pictured above being modded to 256Mb are you doing it for G1nx? Where do you stand so far? Does it work configured to 128Mb?
