 |
|
I just upgraded my gfx card to a nice GeForce 4 TI 4400, (got it for free off a friend) and the performance is great. The only problem is when I
| Code: | | cat /proc/driver/nvidia/agp/status |
It tells me that it is running in AGP 4x. The card supports 8x. Right now, I'm using the agpgart AGP driver. Will I get AGP 8x if I switch to NvAgp? |

One thing you might want to consider is if your motherboard supports it.
You didn't state if you already checked that, just thought I'd throw it out for consideration.

Does your mobo support 8x?
Do a | Code: | | cat /proc/driver/nvidia/agp/host-bridge |
to find out.
Did you add the module (assuming you're loading agpgart as a module) for your mobo chipset e.g. via-agp for via boards?
I've always had best results with the nvidia-kernel ebuild driver. Re-compile your kernel without any agpgart stuff, emerge nvidia-kernel, and use the nvidia module it provides instead.

| I have an nForce2 ultra-400 mobo, but you are right. When I did the checked, it said it didn't support 8x. Is there a way to force support? Stupid me compiled the module directly into the kernel (d'oh!). |

Like I said, recompile your kernel without agpgart, emerge nvidia-kernel, and load the nvidia module it provides instead.

You might check if your bios has the agp 8x setting on  |

This
| Code: | | cat /proc/driver/nvidia/agp/host-bridge |
Will report whether 8x is enabled in the bios anyway.
