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!

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

Follow your dreams !

Only isolate PIN49B.

Did you test it?

What drives do you use?

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 ?


Follow your dreams !

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.

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.

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.

ok, so i had here an old hard drive, and i install on it the winXP - special to test if the adapter is working or not @66MHz.

The answer is no.
I install the Koolsmokey driver, the SFFT, and Amigamerlin: with every of this drivers, i get around 2900 points....so it's working @33MHz.
Aida64 still detects that the pci2pciecard doesn't support 66MHz !

I tested the adapter in PCIe 1x and 16x. - same result
I used two V5 5500 PCI with different bioses. - same result.
I used sell tape to isolate the pin49B on the V5 and to be sure i unsolder the pin on the pci2pcie adapter. - same result.

Btw. i install Koolsmokey and Amigamerlin R3.11 driver under Win7 too, to test them. The performance is low, they are wrking but the 3dmark result is around 1400 points - i belive that the card is working in single chip mode.

@Osckhar: Please post some pictures with your moded card, and with the adapter.
Did Aida64 detect now your pci2pciecard with 66Mhz support ?
Please check if the Pin49B on your pci2pcie adapter is conected to the ground. If not, where is conected ? ( to VDD )

If somebody has other ideeas please coment

Follow your dreams !
