顯卡裡BIOS的設定
 

我的顯卡是ATI AIW 9800 PRO 128MB...想調BIOS讓我顯卡發揮到極限..
以下是我BIOS裡的設定:
SDRAM CAS Latency = 2.5T(DDR) <-要調到3.0T嗎?
AGP Performance Control = Disable
AGP Fast Write Control = Disable
Video Memory Cache Mode = UC
DRAM Burst Length 8QW = Disable

請各位大大看有哪些設定要開啟,謝謝!

如何優化主板BIOS以提昇顯示效率Omega Drivers有寫過一篇參考守則,
有興趣的話可以參考看看..... :yeah:

PERFORMANCE BIOS SETTINGS
(this settings are not avaiable in all motherboards, use only the ones that fit your BIOS)

Fast Gate A20 Option : ENABLED
Video BIOS shadowing : DISABLED
Video BIOS cacheable : DISABLED
xxxxx - xxxxx Shadow : ALL DISABLED
IDE prefetch mode : ENABLED
Init Display First : AGP or PCI (SELECT YOUR CARD TYPE)
IDE HDD Block Mode : ENABLED
IDE 32-bit transfer mode : ENABLED
Assign IRQ for USB : DISABLED (UNLESS YOU USE USB DEVICES)
Assign IRQ for VGA : ENABLED
PCI/VGA palette snoop : DISABLED
PNP OS Installed : ENABLED (WINDOWS XP CAN HANDLE PNP BETTER THAN BIOS)
Resource Controlled By : AUTO (UNLESS YOU WANT TO MANUALLY ASSIGN IRQs AND DMAs)
AGP aperture size : 256 (USE LOWER VALUE IF YOU HAVE TEXTURE PROBLEMS)
AGP master 1 WS write : DISABLED ***
AGP master 1 WS read : DISABLED***
Bank 0/1, 2/3 DRAM timing : TURBO ***
CPU to PCI write buffer : ENABLED
Delayed Transaction : DISABLED ****
DRAM speculative leadoff : ENABLED ***
DRAM Data Integrity Mode : NON-ECC (UNLESS YOU HAVE ECC MEMORY)
Delay DRAM read latch : (THE LOWER, THE FASTER) ***
Fast Writes : DISABLED (ENABLED FOR RADEON 9600 OR ATHLON64 SYSTEMS)
Memory parity/ECC check : DISABLED ***
Passive Release : DISABLED
PCI Concurrency : ENABLED
PCI master 0 WS write : ENABLED ***
RAS active time : (THE LOWER, THE FASTER) ***
RAS to CAS delay : (THE LOWER, THE FASTER) **
Read around write : ENABLED
SDRAM Bank Interleave : 4-bank/way
SDRAM CAS Latency Time : 2 **
SDRAM cycle length : 2 **
SDRAM Precharge control : ENABLED
Spread spectrum (modulation): DISABLED
System BIOS cacheable : DISABLED
Video RAM cacheable : DISABLED
8 bit I/O Recovery Time : 1
16 bit I/O Recovery Time : 1
Turbo frequency : ENABLED


** = ONLY IF YOUR MEMORY SUPPORT IT, OTHERWISE USE THE NEXT HIGHER VALUE

*** = WILL IMPROVE SPEED BUT DECREASES STABILITY, IF YOU HAVE PROBLEMS, CHANGE IT

**** = ENABLE IF YOU EXPERIENCE PROBLEMS WITH CREATIVE SOUND CARDS
