[/i]That's what I've been wondering. I've got the P4s333 and I've got the FSB set to 133. Isn't that the exact same as if I had that board[/i]
No, you have ATA100 onboard while the new one is ATA133. Other than that it's the same, the older one supports 533 but the new one makes it Officially Supports 533. Hope this helps.
