Status Not open for further replies. Previous Next. AGP also supports two optional faster modes, with a throughput of MBps and 1.

It also allows 3-D textures to be stored in main memory rather than video memory. AGP 2. Not all operating systems support AGP because of limited or no driver support. If you plugged it into the wrong motherboard, it would be destroyed.

The "wrong slots" case used to be extremely rare and any manufacturer which made that mistake quickly acquired a very bad reputation. Unfortunately building AGP video cards with the wrong voltage slots is becoming more common. It pays to stick with competent manufacturers. As long as they obey the AGP spec, you cannot damage anything by plugging a video card into a motherboard. There are a few motherboards which do not use the correct AGP connector.

Fortunately, it also has circuitry which prevents damage when a 3. I think they built the motherboard this way as a defense against video cards with incorrect voltage slots.

You can't damage the motherboard or video card even if the video card has the wrong voltage slots with this kind of design. You may also come across the occasional motherboard which has an AGP universal connector covered by a sticker which says "do not insert 3. According to the specification, they shouldn't do that. Perhaps they didn't want to go to the trouble of keeping 1. It's a shame users have to be careful about this because if manufacturers obeyed the specification, it wouldn't be possible to make a mistake.

I also found a picture of a motherboard from one obscure manufacturer which had a universal AGP connector rather than the 1. I doubt it had any circuitry to prevent damage if you inserted a 3.

There isn't a single "AGP 3. Also remember that even if a chipset supports AGP, it doesn't mean that a motherboard using that chipset will always have an AGP slot. The information given above just tells you about their signaling voltage and speed multiplier compatibility. If they're not compatible as described above then they definitely will not work together. But even if the signaling voltages are compatible, there are other things which can occasionally go wrong when you plug the card into the motherboard.

The most common is a motherboard BIOS incompatibility which prevents the motherboard from fully recognizing the video card. The only way to solve that problem is by installing an updated motherboard BIOS. There are other more obscure problems like AGP signal strength and AGP timing issues which can make communications between the motherboard and video card unreliable. Those are very rare but they happen. There's no way to know ahead of time whether you'll have that kind of problem unless you can find other people who have tried the exact same video and motherboard hardware with the exact same BIOS versions.
