AGP running at 2x instead of 4x

Recommended Posts

I've got a Geforce 3 ti200 some crappy spacewalker MB and i'm running XP

 

I installed the latest drivers off Nvida's website and was tweeking then when I notice it tells me it's running at 2x.

Since there is no option to change this with the nivida software I check my Bios. It's set to be running at 4x/

 

I had this problem before with at Geforce 2 and I got a patch that would fix this. Prob is I'm pretty sure that was for my old mother board (the one i broke......don't ask)

 

What this patch tells me to do is open device manager and Click on the PCI-to-PCI bridge. and update the driver to what they gave me.

Problem is there is no PCI-PCI bridge. I do searchers and eveything I can think of but I can't find this thing.

 

Here is what it said

"Go to device manager, right-click on the PCI-PCI bridge

which represents your AGP bridge and select "Properties".

2. Select the "Driver" page and push the "Update Driver"

button. Go through the update driver wizard and on the

"Locate Driver Files" page select "Specify a location"

3. Enter the location of your new INF and driver."

 

 

Ok any idea's on what the problem is here. Anyone had problems with a Nvidia card running at 2x when it should be 4?

I might be wrong here, but I doubt you are going to run into the ceiling on 2x AGP with your setup. I might have a different opinion if you had a 2+ghz system with a GF4 or ATi 9700 Pro series card. The 4x/8x AGP stuff has largely been a marketing move by card manufacturers to provide something 'new'. The cards bottleneck way before they max out the AGP capacity, especially a Ti200 card. If you are not noticing any performance hit from your previous setup I'd just leave it alone.

 

Just looked it up and Spacewalker is a Shuttle series. Not sure if they are good or not, the mobo might be limited to 2x AGP. If you want get the model of the mobo and look it up on the Shuttle site and see 4x is supported.

Hey slap, I replied again to your post in the VI forum.

 

Looked something like this

 

I find my AGP drivers like this. (XP Pro should be similar in all though)

 

Go to view -> Devices by connection Then, it looks something like this:

Thanks rooster. Unfortaly that patch thingy I had didn't work....I did however force to me reformat. Anyway now with Windows installed again i'm back to the same problem. It's running at 2x when it should be running at 4x.

 

Homer, It's not an issue of if my mb supports 4x agp or not. I know it does and I have it enable in the bios

 

Ok anyone have any ideas. Anyone else ever had probls with card with Nvidia drivers running at the wrong bus speed?

ya someone posted about it on goop before....might have even been sim. Anyway I downloaded the newest drivers for my motherboard but the self installer dosn't work.

 

When I go update the sis Graphics port and point it too the drivers i downloaded it dosn't think they are the right drivers...When I install them with the Have disk option It trys to install then restarts my comptuer every time.

I found it based on your description. Oddly enough, I was looking for the info to be buried somewhere instead of right there on the first "tab".

 

Sadly, mine says 4xAGP. Sorry man, but I will keep looking for you.

I'm really starting to wonder If the drivers for my MB are compatable with XP....on the CD there is a folder for win 2k and eveything down but there is no XP. and it looks like the drivers online are the same as the ones on my cd

Question:

My VIA chipset and my GeForce video card support 4X AGP. I have 4X AGP set in BIOS but will only run at 2X AGP. Help!

 

Answer:

 

2 things may cause this.

 

1)If you are using an ApolloPro133A chipset the BIOS may be providing the wrong chipset information to the operating system and identifying it as an ApolloPro133. Nvidia drivers automatically set 4X AGP to off. This registry patch will correct this.

 

2) If you have used a tweaking program for your GeForce card it may have set your VIA chipset 4X AGP to off in the registry. Download and run this patch to correct it.

 

I'm using the ApolloPro133A chipset......I downloaded the patch, restarted still 2x

For good mesure i DL the other patch, restarted.....still 2x
