I purchased new Corsair Vengeance LPX 16 GB (2 x 8 GB) DDR4-3200 RAM and installed it on an existing ASRock Z170 Pro4S ATX LGA1151 motherboard with an existing Intel i7-7700k processor. After enabling the XMP, I found that the system failed to boot (even with stock BIOS). The ASrock website states that the motherboard is compatible with up to 3600Mhz RAM, but I didn't know anything about the QVL list.
I found that the system boots if I set the speed to 2800mhz. I also found that the Corsair Vengeance LPX 16 GB (2 x 8 GB) DDR4-2800 has better timings but is no longer sold locally.
So my questions are: should I just try to make my 3200mhz run like a 2800mhz with better timings? Does this make technical sense? Or should I just try to stick to the QVL list (which is also hard to find locally).
I've never overclocked memory before. CPU and GPU I'm fine with but the 'timings' factor is new to me.
