Dear Maurine,
It’s your fault. You should have bought a RAM kit that it’s actually listed on your motherboard’s QVL. Anything bought off the QVL especially on a AM4 platform has a high chance of not working on advertised speeds or don’t work at all.
I kindly advise you to either return your ram sticks to your seller and get a ram kit that is listed on the QVL of ASUS X470-F.
If you don’t have the ability to return your memory, please take the time to contact CORSAIR’S SUPPORT, ask for the memory comparability of the RAM you got with your motherboard and also inform them for your issue. They might actually replace your ram kit with an actual working one. Corsair got an incredible support and they’ll be more than happy to assist you, trust me
One last suggestion: Go to your BIOS, set VSIO and VCCSA at 1.1V manually. Then go set your ram frequency at 3200MHz and manually put your 16-18-18-38 timings and then set the DRAM Voltage to 1.37V and 1.4V and check if it works outs for you.
Last but not least, please run a memtest86 or windows memtest on stock speeds. If on stock speeds any error occurs then you should RMA the ram either way
