Hopefully this helps someone. I mostly followed this guide: http://rog.asus.com/46212011/rampage-iv-motherboards/rampage-iv-extreme-uefi-bios-guide-for-overclocking-2/
These are my settings with BIOS 1404. Keep in mind, these are high overclock settings with my CPU, Motherboard, and Graphics cards cooled using a custom watercooling solution.Do not attempt these overclock settings with air cooling.Extreme Tweaker settings:
CPU Clock Gen Filter can be on auto, and 10UF would be okay with my settings. I don't know why I left it at 20UF.
My Samsung memory are great overclockers, and since I prefer faster timings, I just keep it at 1866MHz.
CPU VCORE at 1.350 during load using Prime95 will report in CPU-Z 1.392 - 1.400V's with my Load Line Calibration set to Ultra High. It idles as low as 1.376V's in CPU-Z. You don't want to chance anything higher than 1.4V's for supposed degradation.
VTT CPU Voltage needed to be increased to 1.16250V's for better stability to my memory and graphics cards.
2nd VTTCPU Voltage doesn't need as much of an increase.
CPU VCCSA Manual Voltage at 1.1V's is enough for 4x4GB's memory at 1866MHz.
DRAM Voltage at 1.5V's allows full stability at my DRAM overclock and 8-9-9-24-1T timings.
CPU PLL Voltage while I could go as far down to 1.55V's on my SB system, it's probably more reliable to keep it at 1.8V's.
PCH 1.1v Voltage doesn't need to be raised unless you have multiple high-end graphics cards and also overclocking them. If I kept them at 1.1V's, I would have some lock ups and BSOD's of the 0x09 variety.
I disable CPU and PCIE Spread Spectrum.
I don't mess with any of the Tweakers' Paradise settings.
I manually set CPU Ratio to 48 and disable Enhanced Intel SpeedStep Technology since I want to be at 4.8GHz even when idle. It's just my personal preference.
I just set my DRAM timings to 8-9-9-24-1T since I know that's stable.
I prefer my CPU Load-line at Ultra High rather than Extreme.
CPU Current Capability for high overclocks usually don't need to be set higher than 120%.
CPU Fixed Frequency Manual default at 300.
CPU Power Duty Cycle set at Extreme.
Vcore MOS volt. Control at 7V.
VCCSA Load-Line Calibration set at Extreme.
VCCSA Current Capability set to 120%.
VCCSA Fixed Frequency Manual default at 300.
DRAM-AB Current Capability would be fine at 100%, but since I'm overclocking, I set it at 120%.
DRAM-AB Power Phase Control to Optimized.
DRAM-CD Current Capability is also set at 120%.
DRAM-CD Power Phase Control to Optimized.
I believe the only thing I turn on is Intel Virtualization Technology. If you don't have a need for it, you can leave it disabled.
I use Virtualization Technology, so I keep the Intel (R) VT-d setting Enabled.
If you have an SSD, then use ACHI Mode. If you don't, then IDE Mode is fine. If you want to eventually setup a RAID array, then choose RAID Mode.
Just my personal preferences for Boot-up settings.
Anyone have any questions or suggestions for improved settings, let me know.Edited by El_Capitan - 6/28/12 at 7:37pm
