XP333-R 在 PCI/5 的效能一直受到爭議
小弟特別再做一次測試
供大家參考

測試平台:
1. iWill XP333-R (Rev 2.1 BIOS 11/29)
2. AMD XP1600+ (@1.775V)
3. TwinMOS pc2100 cl2 256 MB (@2.7V)
4. Radeon 64MB VIVO
5. 3COM 3C905C-TX
6. Quantum Fireballp AS40.0
7. Pioneer DVD-116
8. Liteon LTR-12101B
9. Teac 1.44MB FDD
10. Delta 300W PSU
11. CoolJag JAC352A
12. ADI G910
13. Microsoft Windows XP Professional

注:
1.CPU 實際時脈皆設定在 1.66G(XP2000+) 左右
但還是是有些微差距

2.FSB=166 PCI=CPU/4 無法完成所有測試
所以改測 FSB=159 PCI=CPU/4

測試結果:
