What's the trick to doing it? I have a F4-4000C18D-16GTZKW kit. I have learned that G.Skill's official response is that with the XMP profile, that simply allows you to boot into Windows and does NOT mean it's stable. I am a little confused why I paid so much extra for this RAM.

With that, how am I supposed to get what I paid for? I kind of feel cheated right now. Not nessarily by G.Skill directly, but all companies that produce high mhz RAM and do not blantantly say, you'll have to overclock the RAM with additional settings in the BIOS. In retrospect, I think I would have rather gone with a recommended 2666mhz kit.
I have a 24/7 stable 4.9ghz overclock on my 8700k. My motherboard is a z370That is when all RAM settings are set to Auto. Presently, I am going for a lower voltage on my OC and stress testing is happening as I type this, but I will work on the RAM next.
What I have tried is using the XMP profile with VCCIO @ 1.225 and VCCSA @ 1.25. That failed after 20 minutes of testing. I called G.Skill personally yesterday and they said try to move the RAM voltage from 1.35 to 1.45. I have not yet tried this.
What should I do to achieve my goal of 4000mhz with this RAM?
We do not have that motherboard rated capable of 4133, only 3733. Note that motherboard manufacturer QVLs do not imply the motherboard is fully capable of the full specs of a memory kit. Typically, it only means the RAM can boot up. The G.Skill QVL shows which combinations we have tested to be fully capable of the RAM specifications, so in the future, it is best to follow the G.Skill QVL.
