In one of the everest pics it shows 32mbs, but what about the bios post?

kk, how do we continue? i have no idea how to solve that sli problem....

i've got an other idea.
what do u think about plugging a v5 pci in a modern pci 2.3 motherboard and trying to enable 66 mhz transfer mode?

in an other thread on the 3dfxzone.it forum, i've read about pin b49 and disconnect it from the card (with clear type or st. like that).
the other thing that has to be modified are the pci registers - theres is an id that shows capability of 66 mhz transfer mode - that would result in agp1x-speed & for me, this is fast enough for the use in modern pc systems.

Yes, you only need a motherboard with PCI-X. The V5 PCI will work to 66MHz bus pci.

Yes, I am fully sure!

You don't need masked pin49 because it already is disconnected. You only need plug the card and voila...

Only is necessary masked pin49 if you are using an AGP2PCI adapter and It must be done on the pci adapter. Wink

Check it:

3DMark2001SE
V5 5500 PCI - PCI-X 66MHz - 3700Points
V5 5500 PCI - PCI 33Mhz - 3000Points
V5 5500 AGP (AGP2PCI modded) - PCI-X 66MHz - 3700Points.

So the PCI-X is the way for Voodoo cards. PCI-X = AGP1x (66MHz).

that is not a bad ideea with PCI-X !
Grin

But i stiil remain to my Projekt; there must be a way to achieve this !
Unfortunately i was very busy last weeks, and the Projekt did not advance anymore... but i hope that next week i will have more time for it.

I still don't find a Datasheet for the missing IC on the V5 AGP4x boards.
I also need a AGP4x Bios, duno where to get it !

I can only rise the VAGP via BIOS to 1.85V. It's a program that allow me to rise it higher ? I think that at around 2V the VSA will be stable im dualchip mode... @IceFire: you have PM !

@IceFire,

In a prevoius post, you mention that your damaged Voodoo5 card, with only one VSA, is able to run at AGP4x.
Please do the following experiment, in order to be sure of that: Connect the A2 AGP Pin of your damaged Voodoo5 board to the Ground.
Please keep us informed about the result.

P.S. I have a reason for that.
I modify my voodoo5, and cut the supply to one VSA. ( the same that is damaged on your board ). Unfortunately i was not able to start the board at AGP4x !
I connect the A2 pin to ground, to be sure that the card will get only 1.5V.
Please do the same.
My card don't start if the molex connector is not pluged. But your did this......

yes, a2 is connected& is working with no probs. but i also need the molex connector to power up the board.

i'll make a video soon... witch lanes did u disconnect?

my card did only once powered up when i caused some shorts on the voodoo5 by adding a new vsa-100 over the socked... but many of the pins where damaged and might caused shorts, so i think the power was somehow taken over the agp bus... after i removed the vsa-100, the card still required a connected molex connector.
