Hello there. I attempted to optimize my memory settings for G.Skill Ripjaws 4 2666C15D. The specs indicate it should run at 2666 15-15-15-35 with 1.2V. When using XMP profile 2, it matches the spec at 16-15-15-35 and 1.36V. CL is set to 16 even when manually adjusted to 15, which works well. I also tried setting all parameters exactly to the spec, including RAM voltage, but the PC wouldn't POST. Could this be related to the RAM or BIOS version on my motherboard? Additionally, I achieved 2993 at 1.36V, though the CPU fan reported 1500rpm idle to maintain those temperatures. Please help clarify.

Are you using the most recent BIOS update compatible with the AGESA code? Please adjust your RAM settings in BIOS to 1.35v manually and enter the required timings. It would be helpful if we could obtain a link to your RAM kit.
