On his Maximus we used the following settings for a quick stability test (1h of Orthos blend priority 5): all timmings on AUTO, only 5-5-3-15 entered manually. 333 strap, 5:6 divider with 460FSB resulting in ~1104Mhz. BIOS 907 if I can remember correctly. Voltage set to 2.0v in BIOS, around 2.05v in Windows. With those settings the kit passes at least 1h, and they can do it with less voltage, I'm sure. That was just a quick test.

Anyway in a few days I'll have my own kit, will post results
