I have issues with my memory when I use the XMP profile for DDR4 @ 3200 mhz. Even when I manually setup the memory. With all the timings filled in manually and also the voltage @ 1.35v. The problem is that my PC doesn't do a normal warm reboot with the memory in 3200mhz. If I cold boot and then restart the system, the system shuts off for 2 seconds, and boots normally, the memory also works stable @ 3200 mhz. It is just that the boot isn't normal. The system doesn't perform a nice warm boot where everything stays on. All HDDs and LEDs shut off. It's like the system goes off/on very quickly when the memory is @ 3200 mhz. But if I set it to 2666mhz default with default timings. It boots normally. I even tried the memory in 1.4v but I don't want to go any further then that.
I'm sorry, but I found it out, was the BIOS, the newest one has this issue. Downgraded to F4 now it's good.
