DDR333 and AGP 8x capable chipset, drops support for PC100/133 SDRAM and 3.3v AGP. Some PCChips/ECS/Matsonic boards uses relabels of the VIA P4X266/P4X266A/P4X266E as P4X333, thus false advertsing.

Like it's predecesor, the P4X333 was still an "ilegal" Pentium 4 chipset.

Key features are:

• 400/533 MHz FSB speed, supports Pentium 4/Celeron processors with the Willamette and Northwood cores
• Up to 4 GB of DDR 200/266/333
• AGP 8x Support
• 533 MB/s VIA V-Link interconnect
• Paried with the VT8235 southbridge
