Sugestions for VooDoo based projects

[benna]

with 3.5ns rams you can easily overclock the vsa100 to 200mhz AND lower memory timings

Only very few VSA-100s reach 200 MHz. My Voodoo4 4500 PCI already freezed at 180 MHz, my 5500 PCI (2x Titan CUV2AB) and 4500 AGP freeze above 190 MHz ...

Well that is the idea precisely. As far as I know, Voodoos are limited to 166Mhz or little above it, due to the 6ns memories.(6ns memories work at 1/6*10at the power-9=166Mhz). The 4ns ram is clocked at 250Mhz, so that is not going to limit the VSA100. In this case (at least under 250Mhz) if something will freeze, it will surely be the GPU.

Yes, the RAM is the limiting factor in our speed attempts.  the VSA-100 chip is speced at 200Mhz in the tech documentation.  the RAM they used back then was the fastest at the price they paid, so we are stuck with craptastic speeds in the present.......  the board should easily surpass 200Mhz with 3.5ns ram.

I have a suspition. With the original cooling I have benchmarked my Voodoo5 with 3dmark 2001se. I achieved 2522 points if i did the benchmark rigt after i started the computer. After I left my computer running for a half an hour (only listening to music) my score was around 2450. Then I raised the frequency to 181Mhz and I got 2470 points. This all leads me to believe that the GPU't got "tired" and in the end the overclocked card had lower performance than at stock frequency when it was still "cold".
So I changed the cooling. Now my Voodoo has the best cooling that it can get. This way I managed to keep my benchmark result little over 2520 even after extended use. The bad news is that if I overclocked the card to 181Mhz my 3dmark results dropped under 2500 after a few minutes of use at 181Mhz.
Conclusion: The best performance that I have reached with the Voodoo5 5500 is at 166Mhz with the improoved cooling. So probably 3dfx used 6ns memories because they knew that VSA-100 gave the best performance at 166Mhz and that at higher frequencies it would overheat and give lower performances.
Question:Am I wrong? I wouldn't want to solder off 16 memory chips (8 from voodoo, 8 from geforce)and than to solder 8 chips back on the Voodoo just to find out that it was useless, because the VSA-100 cannot handle more Mhz. Anyone has some usefull advice?

Hi! Bloodworm, I have seen one of your posts, where you said, you had some pics about the jumper wires and maybe about the resistor changes for the 128mb voodoo5. Can you plese post them here?

Hi All,

I am going to start working on VSA 100 based projects (mods).

I would like to get some feedback, what you would like to see first.

1) V5 AGP 4X slot support
2) V5 more memory
3) 2x V5 SLI
4) 2x V5 6000 SLI

If you have any ideas your self, please post them. I will take a look at the feasibility.

And ? since you're quoting Hanksemenec ...

I just want... to 3dfx live!!!

Greetings from Russia... :-)

So I don't understand... Where I can read the full "step-by-step" instruction of upgrade voodoo4 32Mb -> 64Mb and voodoo5 64mb -> 128mb??? Add the extra RAM is enough? Or any hardware tricks are needed too? Tell me, please... The army of russian 3dfx card owners and fans are waiting... :-)

[Obi-Wan Kenobi]

I was thinking like Woosh

Yeah theoreticly it's possible but has it been proven yet? I have seen the project from Dennis_F with the 64 meg Voodoo4 4500, by Soldering the extra ram worked but if the card worked with the full 64 MB that would be alot better, since the Bios didn't cope with that, still a shame, but a good idea hehe norries there.

Maybe the Bios is a problem as well. About the SLi idea if we could try out that Metabyte Wicked 3D Parallel Graphics Configuration (PGC) Technology maybe it might get up and running , but I suppose getting that may have been a problem as well, it worked with 2 V3 2KPCI's so why not 6 V5K5 PCI's instead

Anyways the idea's are great, but can they be made a reallity? I hope so would be wonderfull

Hi!
Bloodworm, you said that you own ( from Hank ) some pics/schematics about the jumper wires and maybe about the resistor changes for the 128mb voodoo5.
Can you plese post them here?
We all want them !!!!
On witch video card or Brand SDRAM SIMM was used the HYNIX HY57V283220T (5ns) memory, the only one that should work for the 128 Mb voodoo5 ?
There must be some vendors that use this memory also !

Find this:

Fake ? or ??
BTW: somebody from Germany should try to get in touch with him ...
( Wenn jemmand ihm eine email schreiben wurde konnte sein das wir einige wertvolle informationen kriegen !!! )

This screenshot IS Fake !
It was from x3dfxgamers, a group that stole and inf-modded the amigamerlin drivers.
They once claimed they added 64 MB to a V5-5500, making it a 5800 with 128 MB Ram. No other proof, just this screen.
That was a piece of bullsh!t, like everything else they did.
IMHO the only person that can help adding ram to a 3dfx card is Hank.

Hi,
The memory that is needed for the upgrade, HY57V283220T, is used here :

It's a router called "Draytek Vigor 2900V".
Not cheap at all ( and we need 2 ! ):
