Shponglefan wrote on 2024-04-24, 15:31: Voodoo2 is a 1998 card anyway... 😉 Most of them were manufactured in 1998 or later, sure... but V2 was anounced in November 1997, so for me it would be good fit for 1997 PC, along with PII 300.

I was talking about the unreleased hardware STG4800, a higher clocked refresh of the Kyro2 that was sampled but never put into production in 2002, as part of the progression towards hardware T&L. I know the drivers had it for the released hardware, as it was a purely software solution implemented …

I'll have to see if I can drag it back up but it sounds like the information you're referencing was from the work around 2012 or so when a few people figured out the dongle needed to get proper output (the levels were inverted) on the A0 boards and the very very basic drivers that didn't really …

Mostly true there. The Spectre line was setup with a separate geometry chip (I vaguely remember Sage as the codename) with everything else on a separate chip (Rampage). The entry level line was 1 Sage and 1 Rampage and the high end was 1 Sage and 2 Rampage chips. From the benchmarks that have come …

I think replacing the capacitors in the VRM circuit is a good place to start. They can be dead, even if they are not bulged. I had few boards that did not POST initially and ran perfectly fine after capacitor replacement.

TnT2 m64 can use two GPUs - one is regular NV5 like full 128-bit TNT2 uses. And then there is cost reduced version that physically has only 64-bit bus. Either way, the PCB always has only 64 bits routed as a maximum. 16MB m64 will be always 64-bit. Either using two 32-bit chips or four 16-bit chips …

Photo would help. But 32 MB with only two memory chips is very unlikely. I would bet on 16MB 64-bit. Like this one http://hw-museum.cz/vga/159/nvidia-riva-tnt2-m64-vanta

Hello and welcome :) 250 MHz SDRAM is pretty much impossible on GF2 MX. Most likely this is wrong detection by the software - it thinks you have GF2 MX DDR, happened to me as well. The real clock could be 125 MHz, albeit it is very low, even no-name MX400 should have at least 143 MHz memory clock. …

Indeed, it is weird. But easy problem to fix 😀 Without the cover the pins could be damaged easily, even shorted, so be careful. But it will work without... well, maybe there could be problem with shielding the cable as it won't be grounded on the card side. Might show some interference on the …

It seems the metal "cover" of the connector (I can't find a better expression) on the Voodoo is from a female dsub instead of male dsub. Most likely the previous owner switched it by accident. Remove the screws on both dsubs, then remove the cards metal bracket and then when you have all this done, …

Actually - some Pentium MMX are locked. I have 166MMX and I couldn't set multiplier higher than 2.5x. And another 166MMX ran happily at 3.5x. Anyway, regarding PPro - 3.5x is definitely possible, I used that myself many times on several boards. 4x is also possible but most CPUs won't run at 266 MHz, …

I did some testing few years ago. PPro 1M is on average 10% faster than 256k version. These tests were performed using 32-bit SW only. And some power figures. When fully loades, the CPU alone consumes: PPro 200/256 -> 36W PPro 200/1M -> 48W PPro 233/1M -> 55W And few more, for context: P233 MMX -> …

Consider using some sort of mechanical support, these coolers are heavy - especially copper variants. Also I think they won't cool that much better than original ones - VSA 100 plastic package heat conductivity it very poor, so no matter how big the heatsink is, the chips will always run hot... But …
