I'm trying to overclock my friend's 3960x in the build I made for him (see sig), and the UEFI of the Rampage IV is killing me. I can increase and decrease clock speeds easy enough, but for whatever reason the DRAM speed is going up with it, and we only have RAM rated for DDR3 1600, every time its speed goes above that the overclock fails and it cant boot. Is there a way to decouple the DRAM speed from the BClk frequency? Manual doesn't say anything about it. On a related note, how do I use the clear CMOS button? I've never had a motherboard with one that I've needed to use before. The system is acting a little bit unstable and resetting to safe defaults in the UEFI doesn't change anything. The manual doesn't mention the clear CMOS button at all, so I'm asking here. Thanks in advance for any help.
