Thank you. How can I check that I'm in gearmode 2? Would you assume that would have been enabled in the XMP profile?
just enable XMP in bios, leave rest memory settings to auto, and motherboard will take care of rest.
when you boot to windows, run cpu-z https://www.cpuid.com/softwares/cpu-z.html and click on the memory tab. It will detail the current operation mode of memory installed.
Don't be alarmed DRAM frequency displaying 1600mhz. It is correct as it's Double data rate memory so effective speed is 3200 (for the sake of simplicity).
Furthermore if you click on SPD tab, supported modes for the memory installed will be listed there, along with current operating mode of memory in each slot.

Top man. Thank you very much. That's exactly what I did earlier but will download cpu-z and check it all looks good.

I actually had two XMP options in my BIOS. XMP I and XMP II. No idea what the difference is so just went with the first option.

XMP I - Board optimised timings
(timings optimized by motherboard manufacturer)
XMP II - Default XMP timings
(adhere to timing specified by ram module manufacturer's XMP profile )

Is there a better option or will they essentially do the same thing?
