I'm considering getting HyperX Predator DDR4 3200MHz and running it at 3466mhz, as a lot of b450 boards support this speed. I've found it for £80 (16gb) in the UK so it's quite affordable. According to the review below, the RAM is likely to run upto 3500mhz:

Has anyone tried this before with the same RAM, or can you recommend similar RAM that will overclock to 3466MHZ or more?
UPDATE - I found some a Patriot 3400MHZ 16GB kit for ~£80 , which looks to be the best deal. Apparently it overclocks well too.
