My motherboard min vcore is 2.8V, so I can't install a K6-2, but really I want use an old pentium, for nostalgic. I can't find a period correct card with my budget, and voodoo are very expensive, so I think that my options are geforce4 mx4000 or fx5500, that cost around $30. On ebay I have to pay shipping cost, so these period correct cards are even more expensive...
Sorry for the rez, but I wanted to mention that it really helps if you give us partnumbers. Many boards of that era have undocumented jumper settings and may actually support lower voltages, especially since you mentioned your board is a 430TX.
Whether or not any particular board will work in practice with a lower voltage chip like the K6-2 is another matter as the lower CPU voltages may strain the board beyond what it is build for.
Personally I'd probably just leave it as is (if I were in your position). A working retro PC is already a valuable item as is, especially if it's running perfectly stable right now.
If you really want to change things, you could opt for to add something like a Voodoo 1 or TNT2 M64 or something else contemporary like those, or upgrade mobo and CPU and the whole lot using a more recent board. Perhaps your CPU can be overclocked a bit to 233MHz at least. Many 200MMX CPUs were multiplier locked though with all higher multipliers disabled. There's probably also the FSB overclock (if only to add Cyrix compatibility and because the chipset is often simply capable enough to be overclocked to 75MHz FSB or even 83MHz FSB).
I'm not sure though how much a CPU overclock will help with the Virge though.
Thank you very much. The mobo is a KM-T5-T1 v1.32 . Perhaps a small overclock (233MHz, but I want a Pentium I/MMX, in a future probably I will prepare a powerfull computer, socketA, super socket 7...).
Saddy the chinese graphics card has arrived, computer doesn´t boot, 430tx pci's are 2.1, perhaps this card is 2.2 or 2.3, it doesn't work 🙁. I have buy a gf4 mx4000 that seems PCI 2.1 (not chinise, it is a Jaton).
Voodoo 1 or TNT2 M64 are too expensive for this project. Now I have a p120 (430fx), 16MB, trident9440 (after some time upgrade to a S3 Virge 😮), and a SB that it is really like my computer in 95..98, this the computer that I would have liked to have, a p200 with more RAM and with a "real" 3D card, at the moment is a GF4 because others are to expensive, I like riva tnt2 M64, but at the moment too expensive...(Spain, shipping...)
