AGP Backwards Compatibility
What I'd like to know is whether the latest card are backwards compatible ? Just as 4x wasn't compatible with 1x. Graphics processors of this period use PCI-Express, a general-purpose (not restricted to graphics) standard that supports higher data transfer rates and full-duplex. Also, aren't the slots actually different, like shape or size or something?
New required registers include APBASELO, APBASEHI, AGPCTRL, APSIZE, NEPG, GARTLO, GARTHI. Advertisement aspirant Thread Starter Joined: Dec 10, 2004 Messages: 3 Hi, this is my first post. To create AGP-compatible graphics cards, those chips require an additional PCIe-to-AGP bridge-chip to convert PCIe signals to and from AGP signals. The A7N8X has a red LED that lights up to let you know that the card is incompatible and it also disables the ability to power on the board to prevent i thought about this

If you're not already familiar with forums, watch our Welcome Guide to get started. The card must act as a PCI target, and optionally may act as a PCI master. (AGP 2.0 added a "fast writes" extension which allows PCI writes from the motherboard to Some cards, like Nvidia's GeForce 6 series (except the 6200) or ATI's Radeon X800 series, only have keys for 1.5 V to prevent them from being installed in older mainboards without pabeader Junior Member Joined: Oct 9, 2005 Messages: 20 Likes Received: 0 I have an older AGP 2X Video card.
I would suggest a Radeon 8500 if you have the $200 to spend, or the Gainward GeForce2 Ti/450 if you only have around $100.What's the frequency, Kenneth? They are not compatable.

An AGP video card will work in an AGP Pro slot, however the card must have a registration tab. Agp Vs Pci System memory is made available using the graphics address remapping table (GART), which apportions main memory as needed for texture storage.

As long as you don't pull the Pro sticker off the front of the AGP slot when using a non pro card...everything should be ok, as long as it is a But if you're still worried, you can always run your new video card at a slower AGP setting. Hopefully it is AGP 1.5V, otherwise I will have to build a whole new system for DOOM III and Half Life 2 instead of just buying a new video card. So here's the question.
