ASUS Maximus II Formula - new P45 king?

[Codeman05]

Up PL to 10 for now. 10 is lowest you can go 1:1. Maybe some more vNB will help. Also set DRAM CLK Skew to advance 250

Thanks, that was it, I'm now able to use the 1:1.
I'm booting a 1:1 with 453x9.5 = 4.3GHZ & 906DDR2 as I know this was stable on my prior board.

I can boot but I now fail Prime blend in under 5 minutes on one thread, 10ish on the second.
Looks like I'm hitting another FSB wall. 477x9 w/ 1:1 fails in about 3 seconds.

Bios Settings

How high can I go "safely" on the FSB Term & vNB?
Or do I need to loosen up the memory even though it is running slower?

Thanks guys, sorry for the questions, my first Intel chipset since the NF2
