Hello,
Well, taking into accout the information and advices from Komponent and by reading the mod that the Italian dude did it ( on forumzone.it) , I decided to try myself this mod.
Because a Skt.939 board and a Venice 3500+ CPU were layng around, I decided to try the mod on this platform.
Test System:
Athlon 64 3500+ - Skt.939
Mobo: MSI K8T Neo2-F V2.0
Voodoo5 5500 AGP
512 DDR RAM ( only 266 MHz FSB )
40Gb HDD
Enermax PSU
So, I decided not to Modifiy the AGP Slot on the Motherboard – Reason: if the Mobo get burned, i can change it any time on warranty 8)
So that the next step was to cut the noch on the Voodoo5 card.
After a closer look an the AGP pinout, the pins from 42 to 44 came into discussion.
Pin Side A Side B
42 Reserved 3.3Vaux
43 Ground Ground
44 Reserved Reserved
After a closer look at the voodoo5 card, at these pins, I found out that:
Pins 42 ( both sides ) and 44 are not connected. :P
Pins 43 are connected to ground – this was confirmed by measuring them !
Well for the pin 43 there is a soldering point, witch is for every situation available. ( I thought that in the worst case when the card don't start in the skt.939 Mobo, remains the possibility to rescue the voodoo board by sodering this points to ground – luckely this step was not necessary )
The cutting operation mus be done with very much attention and patience !
Don't hurry up ! Take care to eliminate every metal pieces and any rest that can later cause a electrical shortcut.
You will need the following Tools:

In the Foto you can see the modified card:
(http://img50.imageshack.us/img50/1581/p1010019xi7.jpg)
The area for Pins 42,43 and 44 was cuted. Unfortunately I was afraid to cut deeper in the card, in order not to damage some traces.
This lead to the following problem: the card did not stay very well in the AGP Slot.
This is a problem that should be fixed . ( The AGP Slot on the Mobo can be slightly modifyed....)
So, after this operation, I tried to start the card in my old Epox 8K5A2 board with universal slot. The card started without problems... it was a very happy moment for me ;D . my voodoo card was alive !
Then, the Skt 939 Board must be prepare for the voodoo5.
I started the Mobo with an agp4x card. Then the AGP Voltage in Bios was modified to 1.85 Volts, and the AGP to AGP4x. ( This settings remains available with the moded Voodoo5 card ;D! )

(http://img265.imageshack.us/img265/6071/p1010003yq7.jpg)
Then I pluged the voodoo5 card into the Mobo and .....
The card started !!!!
It was for me a glorios moment.
See the pictures.

(http://img405.imageshack.us/img405/2876/dovada1be8.jpg)
The board is running from about 24 hours – continuously. No freeze, no BSOD...
The K8T800Pro is not hot; no components on the Voodoo board or on the Mobo are excessively hot...everything seems to work fine.
But...
3dmark2001 is hangig up in dual mode.
In single mode there is o problem !
(http://img339.imageshack.us/img339/5100/singelchipsl9.jpg)
I manage to start some games:
Call of Duty – no problems.
Start Treck Armadia – no problems. Even 4xFSAA is working well.
Edie Hard – Nakatomi Platza – no Problems.
Flatout2 – no Problems.
The Benchmark "Final Reality" also run without Problems.
Two Remarks:
1. I did not supply the Pin A34 with 3.3Volts like the italian dude did it – I don't agreed with this. Even the card is not rock stable in all application, I'm sure that Komponent will come with a solution.
I now, that the VSA100 must now operate with 1.5Volt signals.( the AVR Pins Problems..) Now they are probably working still with 3.3V signalling.
2.I did not connect the Pin2 from the Voodoo card on ground. ( TYPEDET ).
Many thanks to Komponent for his advices / informations and to the Italian dude ( ciacara ).
With theyr support / ideas / advices this Projekt was possible.
Please, fell free to comment my experiment.
Regards.
Radu.
Wow, nice. But the card still doesn't get AGP4x bandwidth, I assume. Is it really necessary to set 1,85 VAGP? It's far out of spec, so maybe something may burn after a couple of weeks ...

EXCELLENT WORK!! i really hope u can get SLI mode (dual)
i guess u should supply the Pin A34 with 3.3Volts.....
but i would connect
pin A43 and B43 to Ground Ground
and B42 to 3.3Vaux
BYE!
well he did get SLI working otherwise FSAA x4 wouldn't work in the games he tested ;)
Nice Work... but what about you actually carefully remove the AGP slot's notch instead of cutting the video card? There would still be nothing connecting those pins....
You have tree possibility to use the V5 card into an AGP4x/8x board.
1 - by cutting the noch on the AGP Mobo Slot.
2 - by cutting the V5 card.
3 - by using an AGP riser
The second possibility allow you to use the card also in other Mobo's.
I choose the first solution becouse of the above mentionated reason.
But the most ellegant solution remain of course an AGP riser.
Br.
Radu.
P.S. Fell free to start your own experiment, and please keep us informed about the result.
hmm interesting Mod
you voodoo now used only one chipset for all aplications 3d ??
like Voodoo 4500 ??
if you got balls of steel :) can do RAIL mod
connect from line 3,3v to Agp pin (backside mobo) and hapying agp 3,3v
But ... this mod is only for Card 3,3v like voodoo 5k
hehe,
i think that for putting 3.3V on the AGP pin, just like that, balls of stell are not enough :D
I know that the italian dude did like that, but..i'm a little bit sceptical about this...
That's IMHO pure suicide !
Card and Mobo can easly get burned......
For the moment, the projekt status is the same..no news more about..i hope that Hank will came with the salvaging solution !
[:p]
Hello there cool mod, do you know how you can increase the volt to the cpu with the current mb?? I have the same board, since i burned my last one,lol, and now i found only this board for 939 and agp and i cant find the cpu volt setting.Does it need a mod or something???
Well, i did not pay attention to this issue.
The above system is not working anymore ( i give the memory to a frined ), but i will check this as soon as i get it running.
Hi M14radu,
I wanted to get my Compliments for the change you made on the Voodoo5, works very well! ;)
I have a beautiful new, direct power to do Voodoo5 5500 with 3.3 v! :D

Come into my Thread, you can speak English ;)
We expect all. :)
Bye. :D
Hi Ciacara,
Compliments to u too !
It was your idea and i just copy and try the mod !
Nice to see that you are making good Progress.
It's a great Projekt, and the result seems to be very nice !
Can u pls post a guide about the entyre mod procedure ?
You provided directly to the VDDQ Lines 3.3V. It's not to dangerous for the card and Mobo ?
It's the dual mode ( SLI ) working properly ?
In the video is to see only the 3dmark2001 demo !

P.S. Topic on Falconfly Forum: http://www.falconfly-central.de/cgi-bin/yabb/YaBB.pl?board=general;action=display;num=1185303152
Many thanks m14radu :D
I am preparing the English translation in my thread, I wrote a part ;)
I believe that the mainboard AN7 has an internal system of protection, v 3.3 are limited slot Agp
I tried on a voodoo Asrock 4CoreDual-Sata2 chipset Via PT880 Pro but does not work ....... momentarily ;)
I can not prove voodoo in sli because I have only two 5500 Agp 2x [:(]
The video shows the bios settings, you should see the screen
We see that the agp is set to 1.55 v while the screen voltages
Agp Vdqq and 3.37 v ;)

However tell me what you want to see, games, Benchmarck, test, Overclock .... I see what you want! ;)
Thanks for the link on Falconfly Topic of Forum :)
Hi Ciacara,
I saw the movies and pictures...
To check if the SLI is working properly, you should install the 3dfx utilities.( Or V-Control )
After that you have the possibility to choose between single chip and dual chip function.
Your 3DMark2001 Benchmark result is low, indicating that you are using the voodoo5 card in single chip mode. ( like a Voodoo4 ).
My modded voodoo5 works also well in single chip mode, but when switching to dual mode ( when both VSA are used ) the sistem freeze after short time.
Can u please try this benchmark im dual chip mode ?
The score should be around 2800 points, for a regular voodoo5.
Do u know if the VIA K8T800 has also such a 3.3V protection ? This modding is dangerous, because you exceed the customer specifications....
The best ans safe way will be to force the VSA chip to work with 1.5V signaling - then no additional 3.3V supply will be needed.
Unfortunately, i was not able yet to get the card working with 1.5V signaling.
A Datasheet for the VSA chip is also avalable, and may be useful.
I have to search the link....
Radu.

I believe that the Via Chipset (400/600/800/880) does not have this protection, I tried all the mainboard freezes...[:(]

Without Vdqq 3.3 v ram the works?
However, I can say that I have solved the problems of stability with the power to 3.3 v, before I had your same problem ...;)

Ok, I try to look for the link ;)
Maybe the nforce series ( Nforce2 and Nforce3 ) have this protection.
did u read this somwhere ?
I wait your SLI result !!!
Br.
Radu.
P.S. Here is the databook : http://3dfx.rule.lv/downloads/DATABOOK.PDF
I think that it will be easyer to find only one common soldering pin that lead to all VDDQ pins, and then to supply him with 3.3V.
One soldering point instead of 5 !
Can u switch to AGP4x in Bios ?

One point instead of 5 is excellent, the problem is that I have to test it on many Mainboard, Sis, Via, Intel ...;)
If you want to use only PinOut Mainboard of the A34, not Mod. The Voodoo ;)
Quote

You can go from a 4x bios, but the Voodoo was not activated as Agp4x only 2x ...
I have good news for you, I turned on the bus Agp4x with Voodoo in sli, to do this, I built an adapter with potentiometer from 50k ;)

Starting with the Mainboard Vddq 1.95 v / v 2.00, Windows 3.35 Vddq increase the v, the Voodoo is Stable!

Good Job ciacara !
Well, i must admit that i'm impressed about that.:D :D :D
You really did it !
And it's working at full potential !
[:p]
Please run the benchmark with AGP2x setting and with AGP4x setting ( via BIOS ) and tell us the difference..if they exist.
Thgeoreticaly, u have now a AGP4x compatible voodoo5 !
It must, also theoreticaly, work in every AGP4x Motherboard !
The next step will be to find out witch chipset agree this overvoltage ! ( i bet that nforce3 chipset will agree this )
This is the biggest risk, to test the modded voodoo on different platforms.....
I must admit that i'm a little bit affraid to do this mod on my Mobo !
The other possible risk is that after a while, the voodoo will die because of this modding.
But it's only my presumption.
Please do the translation on intalian forum, so that everybody could copy and test this mod. I'm sure, that this will be very helpful !
Once again, good Work !:)
Br.
Radu.
Thanks m14radu :)
Just can, prepare the translation of Thred and I will be testing bios you asked ;)
We made a big step forward with this Mod ;)
bye :)
Translation completed ;)
Good Night :)
how do u connect the potentiometer ?
You mean that 1.95V / 2V it's enough to get the voodoo stable ?
Bios voltage VAGP is 2.0V ?
My Motherboard only alow me to rise the VAGP to 1.85V...if the VAGP is 2V it's enought ????
do u have any other platform available to test the voodoo5 ?
Br.
Radu.

The adapter / potentiometer connect this:
5 v ---> adapter ---> Voodoo modded
Or:
5 v ---> adapter ---> modded Mainboard

In three weeks I can try five Mainboard, then you know I will ;)
Now try to overclock the voodoo5 !
Last time you managed to run it stable at 192 MHz.
You should gain more points in 3dMark2001 !

am i missing something or would the easiest way to make this mod be to desolder the keyed agp connector from the motherboard and resolder a non keyed connector from an older motherboard???
thanks, and GREAT work to keep the voodoos on modern platforms.
This topic is now sticky.
Thank you ciacara :)

Hello princess,
You can use an old agp slots, you need to remove the Pinout not use ;)

i've got an epox 8kda3+ board with the nforce3 250GB chipset running my v4 and i do not see this voltage available, though there may be a modded bios that provides it.
try using the Motherboard monitor ( MBM ) Tool.
hey duys
Your on some insane mods. Im too scared ill fry my card.
i have some weird little thingy built up, Still needs some old parts but i whant to
know how it runs when completed.
I'm running :
duel Slot one p3 server mainboard with intel chipset
2x p3 500mhz psu's - im looking for the old coppermine 1.0ghz cpu's
my ram sucks , 4x 128 pc 133
ide 100 hdd but my board has scsi , still looking for the hdd
vsa100 voodoo 5500
it runs well is there any sugesstions?
shuko :)
I think you don't need to mod your v5 to run in this pc
Any updates to this mod?? Whats the outcome?
There are AGP Riser cards. They can be easily undertaken this mod I think. So V5 will work in AGP4x Mobo with it. I will try this. Were can i see the exact steps ?
Thanks
You are in the right topic.
Read it from the start, and you will see all the needed stepts.
Please put your result here.
I've got an MSI KT3 Ultra2-R motherboard, and I'm thinking about doing something like this. I have a PSU that supports SATA and I'm thinking about trying to hook up an adapter to the back of my motherboard on the AGP slot to go directly to the 3.3v on the SATA plug.
Do I even have to do this with this motherboard, and would it work if I did? What about the signaling voltage? I ask because my setup is very unstable when I have the voodoo in it, and the bios says it's only at 1.85v even though it's supposed to be a universal AGP 2.0 slot (I think).
Well, the MSI KT3 Ultra2-R features the VIA KT333 chipset, witch is able to handle 3.3V ( AGP1X/2X ) - fully vompatible with voodoo !
You don't need to supply the card via SATA connector.
Just plug and play.
Here you can find the card specifications: http://global.msi.com.tw/index.php?func=proddesc&prod_no=497&maincat_no=1
Yeah, that's what I thought, but in the bios it still says 1.5v unless I raise it to 1.85v. I don't know why, and it is unstable. =/ I've read on various sites that this board isn't supposed to be compatible with the voodoo 5 series without modification...
Afaik there were more KT333 releases ( i think KT333A ), and not all are AGP1x/2x compatible.
Sometimes the BIOS version is the problem. If it's too new/old , it could create problems. Check this issue also and picjk the right version for your need.
This AGP Voltage value 1.5V i have also at my SKT939 AGP board on witch i made the Projekt V5 AGP4x.
But in this board the voodoo is working stable only in single mode.
In dual mode sistem hangs, and only in 3D applications.
How is the voodoo behave on your board ? You say in your previous post that is unstable ( in single mode ? dual mode ? BSOD ? ). More details pls...
I currently have the latest BIOS version from MSI. I've looked into this, but I can't seem to find any information on this specific problem.
I think I should note that I'm also using a 35w XP-M 2400+ and am having issues with setting the voltage higher, so it barely boots into windows with the L5 mod I made. It defaults to 100mhz x24 and I have to knock it down to 23x from within windows before I run and applications or it will reboot. After that I can get it to run SuperPi through all 32 million digits with no problem. I'm trying to find a bios version that'll let me change the voltage on an XP-M...
I've not tried using it in single mode, but it occasionally has 2d artifacts on the desktop, crashes when opening Half-Life, gets the BSOD shortly after opening Garry's Mod, randomly reboots, etc... When I plug my x1600 in everything works fine though.
Check if the card is stable in single mode.
Did u test the voodoo card in other sistems ?
Maybe the card itself has a problem.
Let us know :)
Try also a clean 3dfx driver install. ( remove the Ati driver complete )
I've tried a clean driver install (removed everything with Driver Cleaner), and tried it in a different system. If works fine in my dad's old PIII with an AGP Pro slot, and fresh drivers don't help either. I'm going to try it in single mode later today; I have to swap it with the Rage 128 I have in here now.
Just put it in and installed the 1.08.04 3dfx Community XP drivers, and I keep getting the 0x0000008E STOP code on the BSOD... trying one chip now.
when you get this BSOD ?
when starting 3D application, or ?
try single chip man !
I always get it when running a 3D application, and sometimes just randomly. I can't for the life of me figure out how to disable the second chip though...
you must choose into the 3dfx Hub between single chip or dual chip.
or use the V-Control from Koolsmoky.
here is the link:
http://www.3dfxzone.it/koolsmoky/vctrl.html
I have V.Control, but I can't remember where you turn off the chip... I think it's on the first tab, but I don't see an option for it.
EDIT: Nvm, found it.
EDIT EDIT: It looks like disabling one chip doesn't change anything either.
Erm... more edit: I tried some different drivers, and it looks like it's just the drivers I was using. It seems to be fine with the newest AmigaMerlin version.
