Which Ram set DDR4 2933MHZ or DDR4 3000mhz is compatible : razer 15.6" 2020 i7 10750 RTX2060

Anyone tell me which ram upgrade to buy for my new laptop? Model stated above: 15.6" razer blade i7 10750 RTX 2060 Don't have serial number as have to wait 2 weeks for new laptop to arrive. Want to order Ram in advance so I'm good to go day my computer arrives. It ships with 16gb but looking to purchase the full 2 x32gb possible. Are both DDR4 2933MHZ & DDR4 3000MHZ Compatible? I have better pricing & Manufacturer options for 3000mhz so would buy that if it's compatible. Razer have been unhelpful via live chat, email or phone. They refuse to help w/o serial number (but they must be able to identify model from specs as only one laptop matched that?!). An agent suggested my model had a reference if RZ09 - 0328 & that I needed X2 2933mhz but it's a lot to spend with little reassurance. Anyone out there that can help me?
