Btw. What's the difference between 400/800 and 333/667? Aren't they both 1:1 ?
You are quite correct 400/800 & 333/667 are both 1:1 but they use different straps. The 400 strap should be easier to run than the 333 strap but I haven't actually tested it on this board. It wont cost you anything but time to play/try the 333 strap so IMO its worth a go.

My ram should do 533 on 1:1 without timings slackening. It's DDR2-1100MHz cl5-5-5-15 by default. Moreover I've tested 1000MHz and 1100MHz without rising FSB (on other DRAM:FSB dividers) and it fact RAM is stable not to mention about problems with bios-post (C1 on post-led).
I was referring to slackening the timings off from my 2gb setting if you were trying my exact timings as posted. My 4GB kits would not even run tRFC at 28~30 they need to be 46 + to get any joy out of them.
