3DFX Voodoo5 5500 works on PCI-Express !!

[m14radu]

We can try: isolate pin 49, on adapter or on the voodoo, or both !

Let's wait for a confirmation from Koolsmokey

BTW: I am interested why the voodoo is working in a PCI-X slot....the pin 49 is also conected to the ground, and therefore the voodoo should work @33MHz.

GOOD NEWS!

Adapter works to 66MHz if you isolate the PIN49 directly on V5-5500 PCI.

I tested it and now I got 3700 points using pcie2pci adapter!

Good Work Osckhar !

Good Work Osckhar !

You gave me interesting info. So, good work you as well!

Isolating directly the V5-5500 PCI forces  pcie2pci adapter to work to 66MHz.

If we don't want to isolate the V5. Then we should mod the pcie2pci directly in the PIN49 to force it works 66MHz.

Finally, we have managed to get the adapter works for our loved 3Dfx cards.

Finally we get it

You isolated Pin 49 A and B ?

now is interesting what performance increase is to achieve with the v56k, using both adapters running @66MHz

Damn...i need an agp2pci adapter

Only isolate PIN49B.

Did you test it?

What drives do you use?

[m14radu]

Like this, yes ?



I'm using SFFT 1.6 under Win7 32 bits.
i use PCI-E 16x, i isolate this pin but is not working

Your adapter is the same as mine ?

[osckhar]

Yes, isolate only that PIN.

Nope, I have other version the adapter but try it with beta Kool driver with agp2pci adapter bug fixed and let me know but this driver only  works under WinXP/2K.

[m14radu]

you have a link for the driver ?

this one ? https://www.3dfxzone.it/news/reader.php?objid=5280

Ok, i install it under win7.
And it's work ...but very very slow ! i got only 1470 points....

Yupe!

[m14radu]

i will try to unsolder the pin....
i have no other ideea....

[goriath]

Well done radu;)

Have you tried the adapter into 1x pci-e? Does it work @66MHz into a 16x (8x/4x) lane too?

Remove the welding on the PCB where the pin is soldered; then lift it up slightly.

[m14radu]

done, pin is unsolder.
now i test again

L.E. the same results. Card still operates @33MHz.

@Radu,

Install WinXP and uses Beta Kool driver with agp2pci adapter bug fixed and let me know. I am sure your adapter will work ok.

Remember- Core used on SFFT driver has a bug when your are using any chip bridge. This bug were fixed by Kool in such realease driver. Without any adapter chip bridge SFFT works ok but when adapter is used then the card is penalized in the performance.

Next step would be if SFFT wants to fix such bug in his amazing driver. He only needs to talk with Kool.
