AGP card in PCI mode... Help!

By slowbiz ·
Ok, I just got a new system and a new video card.

Intel Pentium 4 2.0 GHz
Asrock P4i65GV Motherboard - Bios ver. 1.7
512 Mb of some PC3200 Ram (I don't know what the timings are)
Nvidia GeForce FX 5900XT 128MB
sub-par generic case with a 350 watt power supply
80 GB WD HDD

My problem is this. My Geforce card says it's running in PCI mode, and on anything high end, it lags like a trident 256 color card. The motherboard's bios won't let me disable the onboard video card. I disabled the card from windows, and installed the new card. Still, it says it's in PCI mode. The only video card options the bios gives me is the video priority (agi/pci/onboard), and I've tried all the options there. On the asrock website, it says the board has a special 'AGI' vga upgrade slot that is agp compatable. There's a list of 'agi' compatable cards, and mine's not on there. I don't think that should matter in terms of getting some 8x AGP support for the geforce card. Anyways, this is driving me nuts. Please help me, as Doom 3 is coming in the mail tomorrow. Thanks so much.

I think the onboard video is causing the problem. Go to BIOS and disable it. See BIOS, Advanced BIOS, Chipset Configuration and set OnBoard VGA Share Memory to [None].
BTW, the 5900XT is not listed as a supported card on the Asrock website.

Like I said above, the bios will not let me disable the onboard or even change the vga share memory of it. I can only change the priority of the video devices. I think the supported cards for that board are in regards to the special 'agi' feature. It shouldn't matter if I just want to use agp.

can you see if there is a BIOS update you can try for your motherboard? sounds like you are stuck with what mb supports...

I have worked a lot with this Mainboard. The AGI is crap. Its a half assed want to be AGP port. If the card is not listed as AGI compatible then dont even use it, you can run the risk of damaging the VC. Your best bet is to get a different Mainboard, and one that has the 8x AGP. The ASROCK board is a great system if you dont need graphics, and use the machine for web browsing and that sort of thing. A word of caution with Intel chipsets and mainboards, they like pulling this crap. MSI did it on a few boards about a year ago. The port looks like AGP, the AGP card fits but will not work.
