Posted - 25/07/2007 : 07:58:15 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:

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! )


Then I pluged the voodoo5 card into the Mobo and ….. The card started !!!!
It was for me a glorios moment. See the pictures.



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 !

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.

Posted - 18/08/2008 : 21:50:24 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. |

Posted - 18/08/2008 : 19:06:09 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 |

Posted - 18/08/2008 : 18:58:39 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... |

Posted - 18/08/2008 : 13:19:59 when you get this BSOD ? when starting 3D application, or ?
try single chip man ! |

Posted - 18/08/2008 : 08:31:20 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. |

Posted - 17/08/2008 : 20:48:04 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. |

Posted - 17/08/2008 : 09:46:16 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 ) |

Posted - 17/08/2008 : 08:15:38 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. |

Posted - 17/08/2008 : 07:53:18 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...

Posted - 17/08/2008 : 07:19:50 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... |

Posted - 17/08/2008 : 06:52:40 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 |

Posted - 17/08/2008 : 04:28:11 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). |

Posted - 26/06/2008 : 12:23:41 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 |

Posted - 15/04/2008 : 22:13:02 Any updates to this mod?? Whats the outcome? |
