Being a new to this and your ram is new as well, yes you should. It will teach if the ram is good even at low speeds or needs to be returned. I have gotten bad new ram on more then one occasion. Anyways once you know it works when you "over clock" it and test it you know a settings is right, wrong or the speed is too fast for the CPU's memory controller or the ram itself should you overclock past 3200mhz ( you can do that
the 3200mhz is just the guaranteed speed the ram will operate at). As stated hitting 3200mhz on an Intel 8th/9th Gen CPU should be zero problem. If you can hit a CMD rate of T1 that is ideal for system responsiveness, assuming it is stable. So short story long memtest86 will is a great tool to ensure your OC's ram is running properly.
