2 voodoo 2s

[digio]

im trying 2 get 2 voodoos runnin side by side with no luck.i have the sli cable for them .the mobo is a pc chips tx pro ii with four meg shared mem.the first card is 12 meg and works fine, the second is 8 meg they both work fine on there own ,and they load everything (windows that is)when they r slid ,but if i go to display properties and select the voodoo tab the usual flicker happens with the first card but the second card freezes the machine but i can end task it,also when it freezes the hdd goes mad for ages as if its lookin for it.then win 98se and win me comes back to normal after end task ,it plays age of empires no probs but quake iii switches the monitor of just before the id intro ,all seems 2 b tickin away becaaaause i can visualise al the screens i goes threw and i can quit back 2 windows then the monitor comes back on,i read in the manual that they have 2 b identical voodoos does that mean the ram 2,,,,,12mb/8mb, hope u understand let alone help ,,,,,,,,,,,,,,,,so plz help ,,,,,,,,,,,

For SLI to work, the cards must be identical.
Same manufacturer.
Same model.
Same amount of RAM.

There is no way you will get an 8 meg to SLI with a 12 meg.

Kruzin is right here, 12 MB version will never work with 8 MB one, yet, I has once Creative's V2 12 MB and original V2 1000 12 MB from 3Dfx and they worked fine together with reference drivers installed.

thanks u guys i thought so 2 the manual did say they had 2 be identical but no mention of ram sizes THATS 3DFX FOR YA.

I thought there was a way to get two Voodoo 2s with different ram counts to SLI. I could be mistaken though, I have never owned a V2 myself.

[Kruzin]

ND was one of the few to come across a non-matched set of cards that would SLI together. I have heard of several people who have gotten 2 different manufacturers cards to SLI (maybe 5% who have tried). But ND's cards at least had the same amount of RAM (and since CL used reference designs, they worked fine with 3dfx ref. drivers).
But I have never heard of anyone SLI'ing 2 cards with different amounts of RAM.

I remeber my Voodoo2 had what looked like extra memory slots. Can you add memory to get it to work in SLI?

[Eli]

I also remember reading that cards from different manufacturers could be SLI'ed if you use the reference drivers. Now that I think about it I'm probably wrong on the different memory count issue.

I got a good one for you - I have two Creative V2/12megs in SLI configuration. DX8 is installed and the latest drivers from 3DFX (since CL have'nt released any new ones)
I would have thought this would have given me 24megs of video memory! but when I checked the Display Control Panel Applet - It says 16meg total memory!!!! also I check the DirectX Diagnostics - It said 16meg as well! - Any ideas where the missing 8meg is?!

A very puzzled Mac!

Several designs for V2 are available, there're cards with 12 memory modules, or 24 double sided (12 on both sides of the card, linked together). I had both cards with 12 modules, and 12 MB total for each other. And I used reference drivers, CLs' just didn't work, coz CLs' soft will never work on something other then original Creative (had CL TNT2 ULTRA, CL SAVAGE4), they just install for Creative card and ignore the other from 3Dfx. But, as I said, 3Dfxs' reference drivers worked flawlessly.
As for your question, LeBigMac (cool name, Pulp Fiction fan ?), your utility probably reports only Texture Memory, thus giving you 8*2 cards = 16 MB, and ignoring the Frame Buffer (4*2=8 MB total) ... piece of cake http://www.sysopt.com/forum/smile.gif

You can get two different cards from different manuacturers to work in SLI but you need special drivers for it to work. I'm not sure about memory differences but I think they must be the same. Get the mis-matched SLI drivers here:
