不能開AGP 4X?
 

我的主機板是華碩TUSL2-C,ATI R7500,bios中打開了4X Mode但為何還顯示2X,該如何開啟,那有沒有開啟的軟體呢?

主機板上之內建顯示晶片功能是否已關閉??又主機板所附之驅動程式光
碟是否也已安裝??系統為何呢?:confused:

已關閉了,驅動也灌了,是Win XP

TUSL2-C是via的嗎，如果是的話via的預設是2x，bios開是沒用的。

2x 4x是沒差多少的~~只是數字上比較好看而已~SO~不要太在意...

是Intel 815EP

如果沒記錯的話﹐ 是要改 registry 。

那是什麼請說明一下好嗎,謝謝...

那又要如何改呢?

是從BIOS改嗎??

I get the following information from http://www.leadtek.com/faq.htm and I hope it will help you. But the *.reg files are applied for Nvidia display card. I not sure whether it can be used on ATI Display card.

For users with VIA 4X AGP support chipset motherboards, if you can only run at AGP 2X mode, please check the followings
1.) Check your motherboard BIOS, make sure you have enable the AGP 4X support.
2.) Install the latest Drivers for your Leadtek Graphics card
3.) If the system is still running at AGP 2X mode. the following registry can force the GeForce driver to turn on 4X mode support. The 4X off registry will turn off the AGP support back to 2X mode. (after download the files, double click to install, restart to take effect)
For Win 9X/ME:
4XAGP on registry
ftp://ftp.leadtek.com/usa/via/w9x-viaagp4xon.reg
4XAGP off registry
ftp://ftp.leadtek.com/usa/via/win9x-viaagp4xoff.reg
For Win 2K:
4XAGP on registry
ftp://ftp.leadtek.com/usa/via/w2k-viaagp4xon.reg
4XAGP off registry
ftp://ftp.leadtek.com/usa/via/w2k-viaagp4xoff.reg
4.) Most VIA chipset motherboard BIOS included a function call "AGP driving value". Find this function and try setting this value to DA or EA or E7. This function is related to AGP timing. Tuning the value will help improve the stability.
