Please elaborate on this FSB wall issue when using quad on the Rampage Extreme. The RE is the only motherboard that I could clock my QX9650 to 490Mhz FSB, and 100% stable at 470Mhz, all voltages manual input. My other boards are in my sig, and are limited to under 460Mhz. The BlackOps was a no-go above 430Mhz on quads, so you arn't missing out rob2k

Mezzro, you mention FSB wall, then you say it happens only after clocking 4.2Ghz. What sort of figures were you expecting from this motherboard? Curious as I can't seem to find where this FSB wall happened for you and what settings you've tried from your previous posts. Please link some numbers on what you've tried or your posts seems pointless... as we have no idea what the problem is and cannot duplicate it and come back with suggestions... no offence :/
