Just a quick post for anyone that has this kit and is looking for overclocked settings. These should give you a starting point. No guarantees these will work on every CPU and memory as no two processors or memory modules are exactly the same.
Test ComponentsMaximus IV Extreme - BIOS 1485
Corsair AX1200 PSU
OCZ 120GB Vertex SSD
GSkill Flare 8GB f3-16000CL8D-8GBFLS Memory Kit
Noctua NH-U12P CPU Cooler + 2x120MM fans (push-pull)
You may ignore my CPU overclock settings and choose to substitute your own as parts and cooling allow
BIOS Settings:
tRRD, tRTP, tWTR are all set as tight as DDR3 timing constraints allow at the chipset level.
tRAS can go one clock tighter to 23 if desired (minimum tRAS is tRCD+CAS+tRTP), though some modules might need a touch more VDIMM.
I have set BCLK skew to +100 as it helps with stability on my CPU - you may wish to experiment with this.
