Don't really know why it's happening. Phone manufacturers like apple and Samsung etc have stupidly had demands so it's like less computer ram is being manufactured to make up for the increased demand of mobile companies.
Really shitty thing is I just bought a new z370 board expecting to buy the ram and cpu for it next. Now I can't try my board until ram drops in price. I hope to god it is not DOA as by the time I get the ram it will be next year.
