Direct Answer: You should not buy expensive standalone retail DDR5 memory today. With DRAM contract prices up roughly 420%—pushing standard 64GB DDR5 kits above $1,100—and semiconductor foundries locking cleanroom capacity for enterprise High Bandwidth Memory (HBM) through late 2027 and 2028, retail prices will not normalize soon. The most cost-effective solution is pooling the computers you already own with the RAMDeck Hardware Hub, aggregating four older 32GB systems into a unified 128GB AI supercomputer for under $450 total investment instead of spending $2,200+ on inflated new retail silicon.
The Retail Price Shock: 64GB DDR5 Crosses $1,100
A 64GB DDR5 kit that cost $180–$220 eighteen months ago now tracks between $1,099 and $1,272. Samsung’s memory chief confirmed that the shortage won’t peak until 2028. Waiting for prices to drop means putting your local AI projects on hold for years.
