Video Card W/DVI Out For A KT133 Chipset MB?
I've seen plenty of video cards listed as "AGP 3.0 cards" when in fact they are actually universal 1.5V AGP 3.0 cards. The 2x multiplier is optional.

Universal AGP 3.0 Card Double slotted Supports AGP 3.3v, 1.5V, and 0.8V signaling. http://hcsprogramming.com/video-card/video-card-for-multimedia-home-video-editing-and-authoring.php
AGP 3.0 added support for 0.8 volt signaling but it did not add a new kind of slot. AGP 3.0 Card 1.5V slot Supports only 0.8V signaling. There are some rare exceptions where motherboard and video card manufacturers don't obey the rules. Consumer-oriented video cards which need to draw lots of power usually require you to plug in a disk drive power supply cable.
Each new version added new speeds and signaling voltages. Available speeds 1x, 2x, 4x. An AGP universal motherboard connector has no keys and therefore can accept any kind of AGP card. Help with configuring a Monitor / TV setup How do I remove my video card?
If you try to insert a card without a 3.3V slot into an AGP 3.3V motherboard connector, the card will bump into the connector key and cannot be inserted. Is this a graphics card issue? I've also seen cards listed as "AGP 8X,4X 1.5 volt only" when there is really no such thing. That way they can be compatible with all motherboards and still use lots of power.
AC97 and MC97 - What are they? The table above gives Intel's official names for the various kinds of AGP motherboards allowed by the AGP specifications. There is often an option in the BIOS which allows you to limit the speed to 1x if 2x is not reliable. Will Capture Video but not Audio Standards for Front panel connectors?

The 3.0 specification isn't as clear as the 1.0 and 2.0 specifications on the subject of requiring the lower multiplier but all AGP 3.0 implementations that I've seen support both 8x Cool DVD file can't save as an MPEG Dell Display problems iPod battery issues Sound Card Problem Screen Freeze, Ahhhh!!!!

AGP 1.5V Card 1.5V slot Supports only 1.5V signaling.
High-end motherboards are often actually AGP Pro motherboards because they can accept both AGP cards and AGP Pro cards. get redirected here AGP compatibility for sticklers: The Long Version AGP Basics In 1996, Intel introduced AGP 1.0. Available speeds 1x, 2x at 3.3V and 1x, 2x, 4x at 1.5V. Available speeds 1x, 2x at 3.3V and 1x, 2x, 4x at 1.5V and 4x, 8x at 0.8V.
The AGP 2.0 specification has a similar requirement. 2x and 1x support at 1.5 volts are required and 4x support is optional. Motherboard Types (table 15 from the AGP 3.0 specification) Motherboard Types Connector Type Description AGP 3.3V Motherboard 3.3V keyed Supports only 3.3V signaling. Available speeds 4x, 8x. navigate to this website AGP 3.0 Motherboard 1.5V keyed Supports only 0.8V signaling.
AGP was a modified version of PCI designed to speed up transfers to video cards. Otherwise they run at 1x which is always implemented by all AGP 1.0 video cards and motherboards. You can download the final AGP 3.0 specification from here.
But AGP Pro video cards are rarely seen outside the workstation market because they aren't compatible with AGP motherboards.

By default, when the AGP 1.0 machine powers up it selects the fastest speed multiplier supported by both the video card and the motherboard. What they are trying to tell you is that it's a universal 1.5V AGP 3.0 card and doesn't support 3.3 volts. Available speeds 1x, 2x at 3.3V and 1x, 2x, 4x at 1.5V. new music format.
Available speeds 4x, 8x. AGP motherboards are not compatible with AGP Pro video cards. You only need to make sure that the video card and motherboard have at least one signaling voltage in common. my review here Video Format No Sounds from Win98se New Graphics Card, When Gaming Monitor Goes Dead!
Likewise an AGP 1.5V motherboard connector can only accept AGP cards with the 1.5V slot. Best burning software? AGP Version Signaling Voltage Peak Speeds AGP 1.0 3.3 volts 1x at 267MB/s, 2x at 533MB/s AGP 2.0 1.5 volts 1x at 267MB/s, 2x at 533MB/s, 4x at 1067MB/s AGP 3.0 The table above gives Intel's official names for the various kinds of AGP cards allowed by the AGP specifications.
Available speeds 1x, 2x. Available speeds 1x, 2x, 4x at 1.5V and 4x, 8x at 0.8V. Looking at the various possible signaling voltages and speed multipliers, you might think that there are a large number of different kinds of video cards and motherboards supporting various combinations of Available speeds 1x, 2x, 4x at 1.5V and 4x, 8x at 0.8V.
The AGP 1.0 specification requires that all implementations support the 1x speed multiplier at 3.3 volts. As a result, you can completely ignore speed multipliers when you're checking for compatibility between an AGP video card and an AGP motherboard. If the card has both slots then it can use both signaling voltages. You may also want to look at the AGP 1.0 specification, the AGP 2.0 specification, and the AGP Pro 1.1a specification.
But it's actually much simpler than that. If they both support 2x then they will run at 2x. The technical specifications for motherboards tend to be just as sloppy as they are for video cards. AGP 1.5V Motherboard 1.5V keyed Supports only 1.5V signaling.
The AGP 3.0 specification requires support for 8x.

Additional electrical ID to prevent 1.5V operation.
There's no such thing as a 3.3 volt video card or motherboard which only supports 2x. From that information and the voltage slots on a picture of the video card, you can often figure out exactly what it is. Universal 1.5V AGP 3.0 Motherboard 1.5V keyed Supports 1.5V and 0.8V signaling.
