Problemer med AGP 4x

[TomRon]

Når jeg kjører på AGP 4x får jeg flimmer i grafikken. Dette blir borte når jeg kjører 2x. Jeg kjørte 4x i en periode, men så oppstod dette problemet helt plutselig. Jeg har et Creative GeForce4 Ti4600 128Mb skjermkort, og bruker PIII 800MHz. En kamerat av meg har akkurat samme problemet med en helt annen maskin. Skjermkortet hans er et Daytona GeForce3 Ti200 128Mb.

 

Noen som vet hva AGP apperture size bør stå på i bios med mitt kort? Er litt usikker på dette...

Tror du kan sette den til 256.

[MrGod]

Mener at den skal stå på det samme som antall MB ram du har på sjermkortet... altså 128 MB.. Visst ikke jeg blander det med texture-size da...

[Bisarre]

Jeg mener at den skal stå på max halvparten av systemminnet ditt.

Before we even enter Windows, a few small tweaks can be carried out to improve your graphical performance. Even though they won't give the performance increases that overclocking will give, they are worthwhile and very easy to carry out.

 

 

AGP Aperture Size

 

This number, measured in MB, represents how much of your system memory is available to the video card. This allows the video card to use data in the system memory instead of its own memory, and it allows textures to be stored in the system memory when they cannot fit in the video cards own memory. Obviously you need to set this effectively, or you will lose graphics performance, or even general system performance. Try one of the following settings, and then set it on whichever gives you the best performance.

 

If you have 256MB of RAM or less, set the AGP aperture size to either 1/4 or 1/2 of your system memory, i.e. 256MB computers should set it at 64MB or 128MB. If you have more than 256MB of RAM, you should try and set it at 1/3 or 1/4.

 

 

AGP Mode

 

The PCI bus speed is 33MHz which allows for a maximum data throughput of 133MB/s. While that seems like an impressive number, it actually doesn't give anywhere near the bandwidth needed for applications like 3D games. The AGP bus went some way to change this. The original AGP (1x) had a 66MHz bus speed, which gave maximum bandwidth of 266MB/s. This was then updated to AGP 2x, which gave 533MB/s, and AGP 4x, which gives 1GB/s. The faster bus your video card can handle the better, as more data can be moved in the time period. All new video cards are AGP 4x, but older cards are 2x and even 1x. Set your card to its maximum setting. You should have no stability issues, and you will allow the video card its maximum bandwidth possible. Owners of GeForce 256 card may find they have problems running AGP 2x on VIA chipsets and are thus forced to run it at 1x. If you look around, you can find programs to overcome this problem.
