Will a 512MB AGP video card work in a 256MB AGP slot?

I bought a 512 MB ATI card but I think my slot only goes to 256 because of the bios settings, but I can't see that anywehere on the motherboard specs. I have an Elitegroup 848P-A Motherboard and the ATI Radeon 2400PRO video card. The computer won't boot up and only beeps. The bios is up to date, the power supply is more than needed, and the slot works with another AGO card. Thanks in advance for any help!|||BIOS settings are for "AGP aperture", which only concerns MAIN RAM, NOT what's on the video card (I'll explain what it is later).



You'll have to tell us what the beep patterns are, then we can tell you what the problem is. Yes, those beeps have a pattern to them, and tells you what the error is. It's part of POST beep codes.



NOTE: ECS mainboards are very picky about memory, and beep codes often result from bad memory installation. Check your BIOS version and beep codes here:

(AGP aperture is a portion of your main memory reserved for graphics. As you already noticed, your video card has 512 MB, that's more than some PC's have IN TOTAL, and thus, you should NEVER have to worry about AGP Aperture settings)|||install the driver before ading the video card|||the BIOS option you see is the AGP aperture size, which means the amount of system RAM you age giving to the AGP card, not how much RAM the card has on board, to trouble shoot, take out all other option cards or possibly yo are an AGP v1 and your card is AGPv2 (version)

or like AGP 2x, 4x, 8x,

the slots are pretty snug so make sure it's in all the way also|||ATI's newer AGP cards are really made for newer AGP machines. Most people assume they are made to revive older agp machines. These new ATI AGP card require specific bios updates to support them, and since older machines don't get Bios updates for newer cards, most end up not working. The best thing to do is to check the motherboard manufacturer's website and download the latest Bios firmware (check the revisions as this may give you the needed information)|||I can't see why your AGP slot wouldn't accept a 512 Video card. It is more likely that it is not securely in its slot. Make sure the RAM is also pushed in properly, especially if you have touched this at all.



Take out the card and reinsert it firmly in. If the card has both Analog and DVI plugs, you could try both.
