ASUS Maximus II Formula - new P45 king?

[CryptiK]

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

I know these settings were easily stable on the 780i, 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.

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

Your ram should be ok as it is, and your vNB shouldnt need to go higher for chipset stability.

Try +60/+10/+60/+10 on the GTL refs, and enable load line calibration. I'd also drop that vFSB to ~1.3v you shouldnt need 1.4v.

Hello what's the highest Fsb anyone has run with 2x2Gb Bloks???

FSB is not really relevant regarding memory module size, if your 2 x 2GB ram does 550 MHz, your could run 550 FSB.
