One quick comment if anyone want to switch from DDR to DDR2 go for at last 677 or 800 RAM even when you will run it in 533 mode(for better speed eg. 1:1 ratio).
Actually we have two reason not to buy 533 RAM
1st you can have better settings eg. 3-3-3-9 1T
2nd many new boards for example...
Well I run here DDR2-667 CL 3-3-3-9 1T in bios set as 533 for 1:1 performance.
1T setting is rock solid here for several weeks so it must depend of RAM you use and not mobo.

Ok here it come

Here is Sneak preview of ASRock 4CoreDual-SATA2: new board from asrock

Why I post it here is page 3 with memory benchmark at (1:1 ratio) and (4:5 ratio) for 4CoreDual-VSTA with 1.80 bios.
They claim that ASRock has tuned the PT880 Ultra...
I' understand this is old post but have to made one comment.
Look here you say
PCI-E 109 (Async) <-actually PCI-E at 109 is in Sync mode as well when you set FSB to 290.
So guess this board don't care if you set it to Async mode and run it in Sync mode when you set it to speed as it...
I know this message is bit old but didn?t have PCI-E card before to test. Today upgraded my system from AGP to XFX 7900GS PCI-E card and had huge problems with stability just as you said here ?CPU/PCI-E ASync Boots fine to XP and XP Locks up (Graphics stop responding and screen flashes from time...
I also got this board just some days ago and use it with E6420. This CPU is not as good to OC on this board as E4300 or E4400 because max FSB speed you can get is in range from 280 - 310 Mhz. In my case 300 Mhz is rock stable. System won't boot on any faster FSB setting even 301 seems to much...
