Sugestions for VooDoo based projects

[ps47]

I dont think multi chip card (such as voodoo5) would cause more trouble than single chip solution (voodoo3),its all about the special drivers.but I could be wrong,of course..

[Caravel]

The AGP bridge controller chip is reqired for AGP not PCI.  Even AGP cards can still run without a bridge chip in PCI66 mode.

The bridge chip is required by any multi chipped card (2+) in order for it to function as a true AGP device, without the bridge it will default to PCI66 operation as does the Voodoo5 5500AGP.

I think it should work with the V5's as well as the V3's?  I think they dropped the idea only because the AGP bus being only ONE in a motherboard kind of killed the PCI dual cards thingy with a resounding CRUNCH.  the only reason it is coming back now as an Idea is that the PCIE bus will have motherboards with two or more slots, and this makes for some interesting speed boosting eh?  Intel archtecture is the only one right now that will allow more than one PCIE slot in a motherboard, so that is why they are saying it requires an intel for the new stuff..... FYI.  anyone here now anyone at alienware that we could chat up for these V3 prototypes???

well i emailed em 2 months bak about these cards and they gave me a link to the new sli set-up, if we new who the top man of metabyte was we could try that, i heard alienware got him too. to tell you the truth i had no idea alienware even had real techies till i read about there hardware mod on the v3's, i think ill hit up alienware chatrooms for a few days to see if i can dig anything up, hank you ever here of this, from what i read metabyte asked 3dfx for help but 3dfx wasnt interested and then after there daul v2's running without there cable to connect them alienware got interested, see that is also interesting, because the v2's were already set-up for sli they worked, so i think that shows that the v3 hardware mod was for each card not a conection between the two?

Hey bloodworm here's a good litle article, look at bottom where he states in house mod, im wondering how many v3's they modded before they gave up on the idea? -->http://www.tweak3d.net/articles/alienware/

hey i know this is just a little off topic here but im from california. wish it said under everyones name where they were from, be fun to know, wanna get a 3dfx lan party up this summer

now to work, how about this voltage mod ive heard about, can it give an incress over just o/cing?

Hello I'm new here
I was told to come here.. to solve my "problem"
I'd like to get my Voodoo 4 AGP a memory expansion.
So far I got:
means and skills for SMD soldering...
a Voodoo 4 AGP (obviously)
a set of 4 sdram chips identical to those on mine V4
I can get any eventual passive electronic components if needed (heard a rumor about some resistor to be fitted to enable the extra ram)

since I'm not familiar with V4 architecture:
what I need is no rumors, but some info I can succesfully use on my V4

I was also told Hank is the man for the yob
(I chose posting here instead of an email or a PM to him so all interested 3Dfx fans can benefit from such an info)

You just need to solder on the chips and flash the card with a modified BIOS. DenisF is the only one with this BIOS but won't share it (as far as I know). No need for anything else. The resistor was for the V5 if I'm not mistaking.

[st4r4m4m4]

Well if that's all I belive I can handle it in a month or so
1 day for soldering + 29days for bios
I'm not very handy with such stuff but I'll do my best.

Not true.

The second bank of SDRAM will NOT be seen by the board unless the strapping resistor is installed regardless of bios.

Are there any benchmarks of a 64 MiB Voodoo4? :-)

@GDonovan;
Okay, haven't read the post on FF's forum in a while, my apologies for the confusion.

@Raff3DC: The poerson who did this mod, said it got him about 300 extra points in 3DMark2001se.

[st4r4m4m4]

So there is such resistor...
No specific info on that one?

Hi! I have good news for you, people. I found 3.5ns 128bit 86pin sdram's that migt work with our Voodoos.It would not increase the amount of memory, but it could certainly increase the operating frequency. It is called EtronTech "EM638325TS-3.5".(etron.com). This type of memory can still be bought but only in larger amounts. You can find rarely the 4ns version "EM638325TS-4"(wich still is 250Mhz) on some Asus GF2 Mx400 64Mbyte. I will try to put them on my Voodoo5 5500AGP. If I succeed, I will post my results. Regards.

But what would it be good for? GPU and RAM work synchronously on every 3dfx card (except Banshee), so it would clock @ 166 MHz. But you could try to lower timings via BIOS ... and there should be better OC with a nice chip on board.
