the best deal on b-die is $179 for gskill flarex ddr4 3200 at newegg(guaranteed ryzen compatibility). if your just looking for decent memory and arent worried about the timings, especially if your on an intel rig. its almost harder to find memory that wont work with it lol. there are a ton of solid deals on ddr4 2800- 3200 you just have to drill down to the stuff in the $100-$130 range at newegg. almost all of it is 16-18-18 which if its on the qvl for your mb your gtg. if your on intel pretty much anything will work. the rgb stuff is where you pay out of the ear. there are some really slick looking rgb modules out there,
corsair vengeance rgb(solid bar) is the baddest of them all imo. https://www.newegg.com/Product/Product.aspx?Item=N82E16820236426
then gskill of course then the corsair slotted bar stuff. the gskill rgb 3200 and 3600 usually go on sale for sub $150 a couple times a month but maybe not during the holidays. alot of rgb stuff is over priced right now.
if you want b-die and rgb your going to pay $200-$225 manufacturer doesnt matter. its all expensive.
