Larger ram is the more important thing for us, I don't think that faster is going to be worth the effort for the same size, but while we are at it, I definately want to go faster too on top of LARGER. I will start looking at datasheets again and let you know what to look for in the numbering........ the more peeps we have searching the better.......

DenisF, is there any chance that you will make available for the 3Dfx comunity the bios you moded for the 64Mb Voodoo 4500? I understand the amount of work you invested in tweacking and hacking the original Voodoo 4 bios in order to accept double the size of initial RAM and effectively make use of it, but the majority of us don't have the skills to replicate your steps starting like you did, from "zero", but still we are enthusiastic about the ideea. As for the hardware mod, we might handle it (is only about soldering chips in the empty spaces, right?), but without your compatible bios, well ..., it's useless ...
I respect your decision, DenisF, whatever will it be, to share or not to the comunity the moded bios.
PS. Please excuse my poor english ... Although I frequently read the forum at Falconfly's for quite some time, this is my first post here

The only thing to do is add some more RAM, the rest will be determined by the drivers since it has no BIOS There are board level IC's that report the card ID to the drivers. Been there, tried it.

Well this thread is old but the project is quite interesting, so since I felt capable of performing sucht thig I'm heading for it...
I recently got a card off ebay just for the ram (exactly matching with the one of mine 4500)

Since SMD tools are very expensive I'm going to "manufacture" custom tools just for the soldering to fit into one cheap soldering iron, modded for the sole purpouse of SMD ram soldering

Too bad DenisF did not give away a bios dump, It's going to be some hard work on the software point of view.

i was thinking about this again myself since a AMD64 3700 was the last board ive found with agp4x the only way to get more umpf is to mod the v4 agp, so im wondering if it all doesnt lead right to Gary's 4800 or whatever it is called, really a v4 with 64ram and it works, so any extra parts needed or bio's problems might be solved with a look at that card.

Any hint (or even direct instruction) comes handy @BFG3dfx Well first thing I checked... Santo hasen't got a 4800 bios image

Am I miss reading this? "AMD64 3700" Is this an AMD Motherboard with a 4 X AGP that can handle a 3700+ chip?

ya as far as i have been able to find the agp 4x stops at the AMD64 3700 i think its the 754 pin after 3700 they went to i believe the 939 pin(guessing on these pin #'s)

some guy beat my damn 4500 score, he got like 4500 in 2001se, from the speed of his cpu(wasnt all that fast) im pretty sure it was the 3700

so its pretty much the end of the line unless someone can come up with a adapter to use the 66mhz pci to agp, instead of the 33mhz pci to agp

and i know there are those of us that love using the pci v5 or v4 but with the faster cpu's they dont hold up, 33mhz was fast enough for the tbird 1200 or p3 but its time is over, been over

and as some of you will not like to hear if you use the 2001se test and are testing just 3dfx cards against 3dfx cards it is a fair test, in top end systems(2800 barton and up) the agp is much better than the pci, all i can think is the pci 33mhz is a bottle neck between the 3dfx card and the cpu that the agp doesnt have, or to that extent(or i had 2 bad v5 pci cards and 1 bad pci v4 card)

in my nvidia nforce2 board my v4agp card beat my pci v5 card easy, cpu was running at 3200 400fsb

sorry to rattle on gamma, here's the board im looking at because im getting a new micro case that i wanna rock this board has a ton of modern features also
http://www.newegg.com/Product/Product.asp?Item=N82E16813123240&CMP=OTC-pr1c3watc...

ok and this(below) is the shuttle i just picked up, and shuttle tested it with the v5 5500 agp so all is cool, up to a 3.06 p4 at 533fsb, gonna give it a try even though im not a huge intel fan and see how it compares with the EPOX board for AMD, one thing that is nice is its small form factor and i couldnt even find a AMD micro board with 333fsb suport

Anyone know any details on that resistor...
also other details are welcome regarding this project
I really wouldn't wanto to end up with a burnt 4500 and 64MB of matching ram chips
