MSI x470 + Corsair Dominator cannot post over 2133Mhz

System Specs:
MSI x470 Gaming Pro Carbon/Corsair Dominator 2x8GB(CMD16GX4M2B3000C15)/XFX RX 590 FATBOY/Ryzen 2600X/Corsair Hydro 100x AIO/Corsair RM650x/Samsung 970 Evo 250GB/Seagate Barracuda 2TB HDD

I am having issues with my RAM kit not being able to post above 2133Mhz, I've tried both XMP settings available (2800/2933) and manually altered voltages (SOC/DRAM) + Timings and have not yet even been able to get to 2400Mhz. My kit is on MSI's QVL list listed as supported at 2933Mhz. I apologise if I missed anything out and for the formatting but any help/direction would be appreciated.

Thanks.

Are you on the latest BIOS update for your motherboard? Try manually inputting the frequency, timings and voltage in BIOS without enabling D.O.C.P/X.M.P and set the timings to be lax. See if that helps.

Yes, I flashed the latest motherboard UEFI, tried everything again. I have tried turning xmp off and setting everything manually a few times but that didn't work. I haven't yet tried making the timings lax so will try that as soon as I can and edit this post with an update.
Thanks.

EDIT: I'm having no luck making the timings lax so far

I've still not been able to post upon tweaking the voltages further and making the timings more lax. I also tried manually entering SPD info to no avail. I've only been tweaking the main timing config as well as NB/SOC + DRAM voltage. Are there any other voltages/sub-timing options I should try to change?
Thanks.
