Zen 3 memory voltage question

I just got a 5900X and pretty much everything else needed to build my next system bar a graphics card in a few orders over the last couple of months. I just put everything into part picker for reference more than anything else, and I spotted a compatibility warning for the memory kit I picked (Team Group 8Pack RIPPED Edition 16GB (2x8GB) DDR4 PC4-28800C14 3600MHz, 1.40-1.50v VDIMM) :

"Memory operating voltage of 1.5 V exceeds the AMD Zen 3 CPU recommended maximum of 1350 mv+7% (1444.5 mv). This memory module may run at a reduced clock rate to meet the 1350 mv voltage recommendation, or may require running at a voltage greater than the AMD recommended maximum."

My question; should I swap kits to something with lower voltage or is the warning in part picker not warranted?

Dont worry about it, you need those voltage if you wish to overclock to max of that ram or have super tight timings (cl14 3600 be 1.45v probably). Get a standard cl16 kit if you don't like those high voltages and just want to run at 1.35v@3600mhz

What board you got?

Thanks, that is what I was hoping, but as I havnt actually powered everything up yet I figured it would be good to ask here.

The motherboard is a ROG STRIX B550-A.
