I'm encountering a weird situation with my mobo regarding memory clock & timing settings.
I'm using an i7-6700K (4.5Ghz Core & Ring) on a MSI Z270 Gaming Plus mobo, with Kingston HyperX Savage DDR4 (KHX2133C13D4/8GX).
I've always had the RAM's XMP profile enabled which work totally fine at the specified clock & timings (2133Mhz, 13, 13, 13, 36, 278). However, since the XMP profile is rated at only 1.2 volts, I came to think there might be some performance left on the table. (Yes I know that the CPU's mem controller only supports up to 2133Mhz, but getting the overal true latency of the RAM down could benefit performance quite well, especially in games.)
TL;DR I'm trying to OC memory.
But here's the thing; no matter what settings I set in the bios, when I boot into Windows the memory is always running at it's XMP specifications.
Even when I have XMP turned off in the BIOS and manually put in a slower JEDEC profile which are supported according to the RAM sticks itself.
It just doesn't matter how high or low I set any value, it just doesn't set any clock or timing setting...
For example: If I set the memory settings to 2400Mhz @ 1.35v and reboot into BIOS, my BIOS shows that the DDR voltage is set to 1.35v, but that the memory clock speed is still set to 2133Mhz.
However in Windows the memory is always just running at 1.2v regardless of the DDR voltage I manually put in.
Does anyone have a clue as to what I'm doing wrong? Is there perhaps some setting which I need to enable in order to make custom settings work at all?
I've tinkered with settings and been googling my ass off for about 6 hours now. Kinda hope I'm just being stupid and overlooking some obvious thing.
Really hope anyone can help me out!
(P.S. I've reset CMOS by taking out the battery for about 10 minutes, didn't solve it.)
