Hello.
I am receiving a lot of help from Vogons. I would like to thank the various members.
I have two questions.

1. I recently purchased a Voodoo 3 3000 AGP from a used goods market.

However, upon receiving the item, I noticed that two of the gold finger pins appear to be broken.
Looking up the AGP pin map online, it seems they are SBA0 and the VCC 3.3V pin(B15, B16 pin).
I understand that Side Band Addressing is not very meaningful on the Voodoo 3, but the 3.3V power supply pins are a concern.

Will there be any major issues if I use it as is?
(I asked AI, and they said that the remaining voltage supply pins might be overloaded by 8.4%, causing the card to overheat. Is this true?)

For the voltage supply pins and overheat thing, well I think that LLM hallucinated that, even if somehow the other supply pins were "overloaded" by 8.4%(How does that LLM calculated that, does it knows the exact PCB layout? The Voodoo 3 3000 generally use around 15 watts(https://www.techpowerup.com/gpu-specs/voodoo3-3000-agp.c3555) and the AGP standard says that the slot should be able to provide about 48 watts and almost 20 watts on the 3.3 Volt pins alone? 😁), that would not make the card itself overheat.
About the Side Band Addressing thing, while I'm not experienced with the Voodoo 3 itself as I stopped using Voodoo cards after the Voodoo 2 and went to NVIDIA cards, so I cannot be 100% sure, but few graphics cards actually use the Side Band, and most of those that use it only gain a small extra performance from it.

Also these pins according to the pictures seem to be far away enough from components to be easy to jump if they are required, my guess would be no, but someone more experienced with Voodoo 3 cards can confirm that.

2. I am currently using a Tualatin Celeron 1.4GHz on Tyan S1846(FSB 100mhz is max).

Which Tualatin-S (512k) model would have similar performance to this CPU?
My goal is a gaming machine running Windows 98 and DOS; do I really need to switch to the 512k Tualatin model?
(Of course, to do that, I would need to purchase a later BX motherboard that supports FSB 133.)

The difference between the different Tualatin variants are mostly the FSB and the cache:

• Tualatin Celeron - 100Mhz FSB and 256Kb cache, higher latency than the normal, slightly worse prefetching method
• "Normal" non "S" Tualatin - 133Mhz FSB and 256Kb, normal latency
• Tualatin-S - 133Mhz FSB and 512Kb cache

The core performance is the same, the size of the data the program works with decides the performance difference. For DOS games I don't think there will be any difference in felt performance by upgrading to the non Celeron variants, for Win98 I would give a "maybe" for some of the later games.

Hello kneiver,

It seems the damage is not just mechanical but was due to current arcing between B15 and B16. If so then the Avenger GPU might have been damaged too.
Also, since trace to B15 is broken side band addressing with the chipset is not going to work correctly or work at all (If the gpu is not dead, of course).
If you have tools like a multimeter/ohm meter you should measure resistance between gpu vcc and ground.
The 3dfx gurus here can give you more tips and info hopefully.
