It's just infuriating trying to figure out if the sticks can't do the timings/speed, or CPU IMC can't handle it, especially with all the voltages you have to tweak (VCCSA, VCCIOA, VCCIOD, VDIMM, VCORE, VRING, VRIN)!!
Asus M6F and Asrock OCF. Then again I've never had much success with PSC or BBSE on any boards, even stuff like 2133C8 Ripjaws X. This is using multiple CPUs too.
I think something is wrong with the board itself, takes a long time to boot, simple settings fail (even cmos reset).
EDIT stupid H100i usb header cable was the problem.
Testing with Flares, this is how the RTLs are set when booting at 2400. The next divider, 2600, isn't stable enough to make a screenshot to show the settings.
