Hello
There is no native memory divider that will allow for 4266MHz memory speed which is why BCLK was increased when XMP was enabled. With such a a high memory overclock manual tuning should be expected instead of plug n' play.

Try Maximus Tweak mode 2, SA/IO voltage tuning, and/or the single sided 2x8GB Samsung profile for 4133 (which is tuned for performance). 4266 is actually slower than the tuned 4133 profile and should be easier to achieve for most CPUs.

Just tried 4266 tweak mode 2 and SA/IO on auto which shoots their voltage to over 1.3v and the system booted fine but crashed In the first minutes when running
Real Bench with DPC-Watchdog bsod 0x133. I guess It requires a vcore over 1.4v which I don't feel comfortable enough to use for a 24/7 build. However when I set the memory at 4133 CL19 @ 5.1GHz adaptive 1.380v bios/1.392v cpuz my system passed an hour long test of Real Bench and Prime95 with SA/IO 1.225v/1.2v. Unfortunately the single sided 2x8GB Samsung profile for 4133 didn't boot for me at 5.1GHz the timings are pretty Impressive though. Those were my findings I hope you could share some Insight on what's better to push for.
Thanks.

At 5.1Ghz you are likely going to deal with trade offs. You can try the 24/7 Samsung profile again, but with a command rate of 2 to start with. If that doesnt work, increase CAS and tRCD by +1 and see if that helps. After that, you can focus on getting CR1.

Command rate 2 did the trick for me the profile worked thanks. Is CR1 much faster than CR2?
