My English is now worse than I remembered by the look of my posts... Even I when I read now what I did write this morning, even I find this difficult to understand all. Allthough I have a clear picture in my mind, even in my native language, Romanian, it is not easy to make a clean exposure...
I also had the ideea of piggy-back soldering of simmilar 8MB 32bit TSOP2-86 chips ontop of the orriginal ones, pin-by-pin and pin-to-pin solder, except of the chip-select one; to invert the signal from the first chip-select pin from it's PCB trace and to connect it to the piggy-back-modules, but talking only on my behalf, I would exclude working with this type of RAM chips because the pins are each one too close to the neighbors (the nearest pins are in risc of shorts), plus that the pins are too thin and small; I might not be able to solder them by hand (not even using external coonectors, wires from PCB to RAM pins); and I see no point for TSOP86 to try a hot-air soldering with my heat-gun for a piggy-back style. That does not mean that it is a generality; they might even be many members on this board able to do just that, with the right skills and tools given.
The only reason for I considered composing 16bit memory modules is because TSOP5x chips have more space between the pins, and also the pins are larger; I simply find them easyer to work with (especialy by hand). To invert the signaling from the first virtual memory chip from the trace of the chip-select to get a signal for the second one, if this is possible, could also be applied for the composed 16bit modules; this would get us realy close to the first Voodoo5 5500 with 128Mb dream. It would also be necesary to modify the bios to "fool" the VSA100 that it has a connection, but it will empty fire. How to get a CS1 signal from CS0 one, I'm not sure yet.
I say again: I found no ball on the back side of the PCB under the VSA100 that we could use to take chip-select for the second memory bank. I could very well be wrong, so search for it anyone who can, please. With this ball found it would be much, much more easy!
Quote:Hi Komponent,
Nice to see that people like you are still interessting for the V5 Memory Modding.
You have all my Respect
In Order to help you on this "Trying", please tell us what exactly do u need ?
Maybe I or somebody else can help providing you the needed cards.
Geforce2 cards are not very expensive nowadays, so if you could specify exactly the card model, i will search for it!
Radu.
Thanks Radu; but I see nothing special on what I expose here; I feel it is only very old news and the 3DFX fans have been very much aware of those simple facts for a very long time... Please excuse me, friends, if I bother you with my talk; even better, just say if so. I had no computer for a long time so I had no chance to compare what I researched with my old-style methodes with all the previous public facts.
The thing is that I don't like working for other guys with pieces that belong to them, especialy on never tested before mods, because there is allways an important risc of permanent hardware failure. Last year a friend of mine also a member on this forum had a Voodoo4 AGP send to me to add more RAM to it; I did this mod before with succes, yet I killed his video-card while working with it and still now I feel bad because I failed his expectations. I like to work with my stuff for myself because if there is a failure, it is only me feeling sad.
