Help! Am building new system for my mother and she wants to limit cost so would lkie to use her old grapics card listed in title. Can anyone please tell me if this card will work on Epox 8KDA3J mb? Thought I saw when I ordered board that requires 1.5v graphics card, yet I can't seem to find anywhere that tells me the voltage of this card. Any help is apprecated!

Short answer: the TNT2 Vanta LT 8MB is unlikely to be a safe match for an EPoX EP‑8KDA3J. The EPoX board implements an AGP 8× (1.5V) interface, while many Vanta/Vanta‑LT cards were produced as older AGP 2× / 3.3V devices (and a surprising number were even mis‑keyed), so voltage/slot mismatch is a real risk. Because the card you describe does not physically seat in the EP‑8KDA3J slot, it’s already a clear sign of incompatibility — do not force it. EP‑8KDA3J spec. (hardwareluxx.de)

How to verify without guessing: (1) read the card’s PCB/label for a vendor model/part number and look that up — the vendor/OEM datasheet is definitive; (2) inspect the edge connector/keying — a card that won’t insert cleanly is incompatible, and a card that fits may still be the “wrong” voltage on some older models; (3) beware that the slot/key is only a mechanical safety — motherboard voltage detection (TYPEDET / A2) and the card’s actual wiring determine electrical compatibility. Do not file notches or force insertion. See the AGP keying/compatibility notes and why some old cards (Vanta/Vanta LT included) cause problems. AGP keying guide · AGP compatibility details. (playtool.com)

Practical recommendation: since the Vanta won’t seat, replace it with a card explicitly specified for 1.5V / AGP 4×–8× or use a low‑cost PCI video card if the system needs only basic display output. That is the safest, lowest‑risk and lowest‑cost route — forcing mismatched AGP cards can permanently damage the motherboard and the card. The earlier replies from and point in the right direction: physical mismatch + vintage Vanta behaviour are exactly why this setup should be avoided. (flylib.com)

Chances are that TNT2 will be limited to AGP2X, which means a voltage of 3.3V. I wouldn't use the card!

thanks for the reply. On closer inspection, AGP slot is different on mb vs. old card and won't fit anyway. If looking at pins/slot on mb, the "key" is closer to left (from back of computer). AGP slot looks like this:
---------ll---------------------- on mb, and opposite on video card like this: ---------------------------ll---------. Is this how I can tell, for instance without knowing anything about card specs, that it is the new standard of 1.5v?
